Requirements for writing an experimental report
1. The experimental report and the experimental preview report use the same experimental report paper. It can be completed by continuing to add relevant content on the basis of the preview report. Repeated work, so the preview report needs to be standardized and comprehensive first.
2. According to the experimental requirements, when conducting experiments in the laboratory during the experimental time, record the experimental data while measuring. However, in order to make the report accurate and beautiful, the experimental measurement data should be recorded on scratch paper at this time. Wait until you are sorting out the report before copying it onto the lab report paper to avoid filling in the wrong data, causing modifications, and making the report messy.
3. During the experiment, if the experimental measurement data does not match the pre-calculated values, or even differs too much, you should find out the reason at this time, whether it is the original calculation error or there is a problem in the measurement. Let it go, this can only be regarded as an incomplete experiment.
4. The experimental report is not a simple experimental data recording paper. It should have an analysis of the experimental situation. The data measured through the experiment should be compared with the calculated values. If the error is very small (generally less than 5%), then It can be considered to be basically consistent. If the error is large, there should be an error analysis to find out the reasons.
5. The experimental report should have the experimental conclusion of each item, and the conclusion should be drawn through the specific experimental content and specific experimental data analysis (it cannot be said in general that a certain theorem has been verified).
6. Design and comprehensive experiments should draw the designed circuit diagram and mark the selected and determined circuit parameters. There must be a verification process and necessary design instructions.
7. When necessary, a curve needs to be drawn. The curve should have complete scales and units, the proportion of the curve should be appropriate and beautiful, and corresponding explanation and analysis should be made for the curve.
8. At the end of the report, you must complete the thinking questions required in the instruction book.
9. When the experimental report is handed in, it should have the preview scores and operational scores given by the experimental instructor during the experiment, and should have the signature of the instructor, otherwise the report will be invalid.
10. I hope that every student will carefully complete the experimental report. This is an important step in cultivating and exercising comprehensive and summary abilities. It lays a foundation for course design and writing of graduation thesis, and is helpful for future work. and scientific research are also of great benefit.
