Order
I just start the experiment, other people how to say how I do, every day bench next to the dry into the night, thinking that this is a scientific research. Over the past two months, suddenly found they were still marking time. That feeling can only be \I began to question their own behavior and perceptions. Feel the power of a kind used in binding me. Accustomed to others, and used to follow orders, used to busy. I'm not a graduate, but is a cheap and hardworking technicians Bale. Later, students see around repeating the same mistakes, I was surprised at the universality of these issues. So I decided to sum up the experience of scientific research, and our discussion. Approximation of the true sense of hope to the scientific research; hope that these experiences become a graduate student in the group after experiencing tempered accumulation, so then people can learn from and avoid detours to reach the essence of the problem.
would like to thank lilac garden, where I can get in-depth thinking.

I Experience of doing research (a)
I did some research experience
1. half the time to do experiments, half of the time to read the literature.
must not consume all their time in the experimental stage. Read the literature, reading, watching other people's operations, to listen to other people's experiences, research other people's ideas, thinking by doing. To learn to compare, do not follow blindly. Otherwise, it will be some minor problems for a long time.
2. for the more fully, the more successful experiments.
old saying, may quicken work. Pre-knowledge base,
上海团购网, literature reserves, material preparation, method of preparation to avoid running around in circles, full pre-test to make you believe. Step by step, do not have to \The most intolerable is lazy in the first few steps, resulting in the back there are always some obstacles can not be excluded.
3. recorded true and complete.
always a little vanity. Only the successful result of steps or a beautiful mind to experimental records, the practice of many people. As everyone knows, a lot of valuable experience and unexpected discovery that pass you by. Objective, true and detailed records are a valuable asset.
4. Do not save money for the boss.
efficiency first. Calculating the money all day, once with the unreliable things will only waste time, hit the end, and save not a penny.
5. seize the psychological advantage.
done in the experiment have experienced failure and frustration. Some failure should occur in the pre-experimental stage, you then can readily accept. If not do pre-test, encountered in the formal experiment, your frustration is very obvious. If you hurry and because of misuse, you will be depressed. If you can air dry because the current Xin Fu and decisively put off to avoid the tragedy. If you did not know until the morning of the lab to do today, you'd think it over again. The biggest mistake is to repeat the same mistakes. Remember, incorrigible are not suitable for experiments.

5.
hands ready to order to clarify design issues, namely whether the result is positive or negative, can write articles. What positive results indicate that the negative result to what.
positive results obtained if the requirements of the subject, you may want to pre-designed parts, the first part of the event was not the expected results, partially offset by other losses.
I did some research experience (c)
1. Most of the article to see a summary of the article to see a few full text search
mastered a bit of skill, often in order to get full-text for the music, so there is no time to read the contents of the article, even bother to read summary. The full text is not much really useful, too much text is a waste of pursuit, can not go to extremes. Summary of course it is wrong to look at.
2. centralized read Association of Document
forgotten. See more scattered literature of the time, wasting more time. Concentrated time to read more easily,
团购网站大全, to form an overall impression.
3. make a record and marking
copying or printing of documents, direct pen marks or comments. pdf or html format documents, you can use the editor on or change the text color scale. This is to avoid waste of time is another important means. Otherwise, did not mean to see.
4. prepared to personally read the referenced article.
quoted incorrectly relay an erroneous result of too numerous to mention.
5. Note that the reference value of the article.
publication impact factor, the article cited a reference number to reflect the value of the article. But pay attention to the other articles cited in this article is how to evaluate this article: support or oppose the supplement or correction.
I did some research experience (d)
1.
experimental course can not learn to experiment before the experiment class teacher had done the previous steps, to all the problems are resolved, when the class is perfect to let everyone see the final step of the performance. This is the real experiment? At that time we naively asked the teacher: we can go? When is the lab report? For most people, the experimental skills in the laboratory can only \
2. Communication is the best teacher
experiment difficulties of the day. Your first reaction? Try again? Give up? Reading? These practices are reasonable, but should first think of the exchange. The identity of a person, private consult reflect your respect for him; of the same year, who financed and open discussion so that we can speak freely, but cautious about. Do not be behind closed doors. Toss half of an experiment, then they tell you it is a dead end, would it not taken advantage of?
3. the highest level of ability is no better expression
ultimately depend on someone else's work recognized. Skills, reflected in the ability to write and speak, the quality of long-term culture is required. Example, found a rare case of a treatise written fat; write well can only send a case report. Such as making a topic,
团购导航, written a fat one or a few of the articles; not only send a written summary or on the shot. In one picture, a table, no not the expression of competence. Few hundreds of thousands of words on the tender, can win large sums of funds; although the relationship is important, but do not write bad line. Some people say, I do not learn PCR, not study spss, as long as the Society of ppt (powerpoint) on it. These words have little reason, on the surface of the lab boss who is walking by a string of lakes ppt. Graduate Yin Siwei often clear and awe-inspiring agility regulations. Often have graduate students do not understand \
4. to learn English, not to learn a second foreign.
now whether to go to Japan or Europe, academic exchange has long been dominated by English. You do not have to read a French article and regret, to write the article in English and people are anxious for the Mo Xuehao. If you have not yet proficient in English, for the time being not to learn a second foreign.
5.SCI is a trap.
luck! It was not made an effortless SCI article. Do not envy him. As far as I know someone else design issues, is another hands-on experiments to do with him, the article is to help him find a foreign teacher who rewrite, but he is not good at doing research. Because of an article he has since SCI research that can have a go in the world. So to go abroad, to do experiments, to continue to send SCI, to earn dollars. Since then embarked on a road does not belong to him. (Components may be sour grapes.) But look around to see if they really do research for it? Really do not do research for you?
I did some research experience (e)
research on the fraud I do not know to what extent can tolerate, research, and that counterfeiting is not a twins.
but people are talking on stage - not fraud.
1. appropriate fraud: innocuous, little deviation.
paper made for age, ###### matched normal DNA control adults, the actual use of cord blood DNA as control; paper made 200 cases of normal controls, 150 cases actually done; paper are significant differences, there are significant practical difference, but the difference did not mean so much paper; thesis randomized, in fact, free group; thesis to the Animal line of sterile surgical procedures, is actually only the part of the equipment in the disinfectant bubble a bubble.
2. Passive fraud: bite the bullet, the victims. Brother
published papers, tutor to Iraq and then do not repeat them in Iraq, but Iraq can not say that Brother's thesis there is a problem in Iraq did conceal the fact that on the basis of a more \result, Iran will be able to make any findings; a few months before graduation, many people became very successful experiment, the out are out.
3. objectively false: has no intention and is, the lack of common sense.
paper reports a new deletion mutation, is said to pick only one Iraqi cloning and sequencing; a repeated several times in this experiment that did not repeat the article was sent to take it.
4. Active fraud: instant success, rain or shine.
paper electrophoresis in the picture too late to redo a piece, by someone else replace a similar picture; digestion time, there is a band should be completely cut off, but the total cut is not clean, Iraq obliterate it with PHOTOSHOP a; paper in the heavy workload PCR, but PCR instrument using only one of the records of registration; paper, p = 0.041, the actual p = 0.055, the positive control group observed in the case of a remove to be 0.041.
5. positive fraud: chasing fame and fortune, a crazy year Iran signed the papers published in the first 50; first, paper records after the experiment.

English essay writing
1. read the 10 documents, summary of 100 sentence patterns and commonly used phrases . Regular review.
note must be based on the literature of the English native speakers, literature content to your profession.
This is usually a byproduct of Document.
2. to find 3-5 articles and statistical methods and technical routes subject close to your article, intensive reading.
to write a draft paper. In accordance with title, author, abstract, background, objectives, materials, methods, results, discussion, thanks, references, legends, maps, tables, photographs and descriptions of the uniform format for writing. This has the advantage that it can be easily changed from any of the magazine format.

3. for each part of the paper, in particular, is a specific method, to discuss a particular aspect, and find 5-8 articles
reading, enrich and perfect.
discussed here involves only the English expression, they can only recommend to the lack of English writing experience.
4. to find the magazine you want to vote for contributors, find 2-3 articles to the magazine article, according to its format rewritten.
attention must first save each adapted to a different file name, so that a problem can not be restored.
5. to find the English master of change. Can not find the right person to look for papers in English editing services (English correction and improvement, not translation) of the company, this time to the rich people who do not strongly recommended.

Document management
1. Download the electronic version of the document when the (caj, pdf, html), paste the article title as the file name.
Note that the file name can not have special symbols, should \ /: *? | and newlines deleted. Habits of each set in the same file name, you can prevent duplicate downloads. Lilac Garden
electronic journal in October 2003 the first issue of the first phase of
2. different topics into different folders. Folder title should be brief, such as: PD, LTP, PKC, NO.
3. read the literature included in sub-folders, at least should separate the useful and useless.
4. an important document in the file name under the importance of front of 001,002,003 numbers, and then arrange icons by name, the most important literature on the row in front of.
5. copy or print the documents, with the punch (¥ 10-15) drilling,
团购网, hard into the folder (¥ 10-20 / a).
I did some research experience (eight)
we often refer to the references on playing some small smart, not knowing that these will reduce the paper quality.
1. to know without causing
clearly draws on similar work colleagues, but deliberately does not refer to similar work colleagues, to make their work look \In fact is probably the peer reviewers.
2.
deliberately out of context part of the Interception of trying to express a negative view of their own.
3.
argument does not take a good look but not the original, citation errors and omissions.
4. source of false
unreliable source of certain words (such as informal or non-academic publications), and does not indicate the source. Common in the statistics.
5.
blind self-citation is not to explain their work and the relationship between the preliminary work, but simply to improve their articles and citations from the lead.
I did some research experience (nine)
low level of domestic articles of several reasons:
1. reviewers knowledge of the older reviewers old
people search and access documents and the capacity is limited, the study could not verify whether it is meaningful, innovative point where the method is reliable, the results are credible. But the bizarre is that they often mention the reviewers opinion is \
2.
wrong though reviewers generally designates two reviewers, but the editorial department often let people who do not know molecular biology molecular biology review articles, so that people do not understand statistics, Statistical review more complex article. For face-saving, very few people that \
3.
With relations between the article, what is simple.
4.
honestly do not recognize the negative results of the negative results are considered meaningless. No wonder people cry \
5. false
anyone not want to become a victim of the system. Could not get the expected result can not cross. Account for survival, as scheduled graduation
dollars, making it.

dynamic research
1. Research by the accumulation. Roentgen discovered X-ray
like that with a simple observation of the Nobel Prize would have fewer opportunities. More long-term accumulation of research from the laboratory. Ultimately deserved. Do not expect to do research and asking for the moon. Design issues do not aim too high. Fund review as well. No pre-accumulation, potential for funding small. To choose a good instructor: you have to start from scratch, or to Weirenzuojia?
2. documents to be tracked.
Open title when the understanding of the situation by checking the literature, to the end when the question may be very different. During the experiment should pay attention to tracking. Good luck, you can get more clues; bad luck and found someone else first to the. Be amended accordingly to your experiment. Before writing a paper document must be re-check again.
3. records to review.
previous experimental record to regular review. With experience and awareness-raising, you will find the original judge may not be correct.
4. materials to deterioration.
Over time, some reagent will degrade, and some equipment will be aging, which leads you to the previous method is in full accordance with previous results of the lack of. PCR is the devil! Many people feel this way. This is just a simple example.
If a reagent is effective to reduce the amount you need to increase the dosage. If the deterioration after the harmful substances produced, I am afraid of the change agent has. If the device is reading a drift, you have to correction. In short, a problem to find reasons for each step, \Otherwise disregard the changing circumstances.
5. boss to see.
boss is across the river by feeling the stones. Changed his mind at any time. That is bad, he would turn. You want to keep their eyes open to see signs, otherwise they will be transferred halo. Can properly guide it. Interactive Well.

I have the experience to some people than I have to ask \five for example.
1. Scientific research is what pop songs
what, what fashion do. Mouth biochips, closed nanotechnology. Boss is Zhuixingyizu, pop is the best.
2. Scientific research is merely a redirection of
design issues? How is the subject of design come from? Is the spell out. Materials A, B method, C index, D meaning.
3.
shoot cameras is the principle of scientific research do not understand? I am afraid I decrepit, no time to read the principles of the. I can toss, toss a few more came out.
Why do this step? Knew the boss on the line! His family on a week for what I have piling up.
4. Summary of research is to copy or imitate
not write? Copy ah. Papers will not write? Sets ah. Anyway, no one held accountable.无知者无畏!
5.
experimental research is complete rubbish, papers published, the respondent adopted. The boss said in earnest: \
halo! Down! Struggle! Then down!
they did not lie to me, pragmatism has its own reason. But I no longer casually criticize China's scientific research level, because at some point I have to repeat the same story.
I did some research experience (xii)
writing his thesis
1.
not listed first, outlining the outline, up to write, is bad habits. No problem a few hundred words, barely a few thousand words, Jiwan Zi difficult. Writing the outline must be listed, and then fleshed out to ensure the continuity of ideas and words of the balance.
2. to spend more time writing
summary stage work, and writing articles and more contributors. The final stage, the organic combination of these words together, that is a good thesis.
3. Do not list all of the data
order to ensure the thesis component, students are more often observed indicators. But the thesis is not the data the better. We must discard those that have little data on the subject. Otherwise, loose or become a burden, or a flaw.
4. print directly on the computer to modify
changes will be missing a lot of mistakes. To minimize any errors, be sure to print out the changes.
5. let others pointed out that the error
own changes are still subject to the limitations of personal habits. Errors out there, but turn a blind eye. Let someone else pointed out that the error bar, no matter you are not the same profession.

how to read literature
1. Target:
aimlessly then cents inefficiency of focus was inefficient. There may be some time before the topic in a confused state, I do not know where to start. Casually reading a lot of literature, but I do not know why. Under the guidance of instructors, peers, inspired, some people can quickly clear objectives, targeted, entry to start here. Even if the teachers did not lead, no set questions, they would first look to set a specific problem literature. Whatever you do in the future do not do these things much better than no goal to ensure a harvest. The general rules of scientific research are common.
2. level:
for a specific topic, the relevant literature belonging to three levels: research, research, research topic.
For example, some of stem cells for Parkinson's disease, for him, research is Parkinson's disease, Parkinson's disease research is stem cell therapy research is a substance inducing stem cells to secrete dopamine nerve cells. Hand look at the literature to distinguish between when the literature are that level, this decision you have to grasp to what extent it.
research-level literature: general involved, basic knowledge, academic standards, understand the current trend of significant progress and achieve professional level; research-level literature: To focus and hot spots, has been / is / will be subject to expert level; research-level literature: To fully understand the history, current situation, outlook, the main methods, means, to achieve No1 expert level.
correctly identify the level of the article can be used to concentrate the point.
3. Forms:
broad can read all the literature, including published form. Textbooks, monographs, conference abstracts,
北京团购网, journals, web pages, or ppt file. To understand the immune response such as the basic form, is best textbook; to make reference to stereotaxic rat brain atlas, is best monographs; to know the latest progress, it is better access to journals; to understand other people's research trends, the best is a compilation of participants or to see Conference Papers. Do not look for the wrong source of information.
4. Level:
different degrees of familiarity with the literature, reading literature was very different. Novice-learning to read, word for word, to find out the details, grasp the basic knowledge points. The first dozen, dozens to intensive reading, the essence of several or even recite. Veteran search-type reading, various studies have been familiar with the common mode and general routine that can quickly extract key information,
qq团购, and grasp ideas, often do not follow the normal order of reading. Some plug-speak, the number of people identified literacy. Master of critical reading, sharply, pointing the problem. Virtually no paper is impeccable. Novice to steady, veteran to be accurate, hard to master. Novice, veteran, master's representatives are graduate students, tutors and reviewers, but careful study of the graduate students can achieve in 3 years of evolution from novice to expert. Have a clear positioning of their own in order to choose the right way of reading.
5. contradiction:
read more literature, his mind full of information. Public that reasonable, rational woman and she said, but at a loss? To solve this problem, evidence-based medicine clinical trials by the level of evidence; the same token, we have to seriously look at the literature the strength of experimental evidence. Found contradictions, is the first step; to find similarities and differences, is the second step; of solving, is the third step. Derived from the conflicting conclusions found in the root causes of conflict, this time as to jump out of the loop, do not walk mindset, starting from the original scientific problem, \Translation overview of why foreigners lied own review? Why repeat what others did
experimental pretended to be thinking?
thought to write, is not mature enough! How are you opinions.
