Experimental graduation thesis refers to a thesis in which graduates majoring in science and engineering observe, analyze, synthesize and judge the data or phenomena obtained in scientific experiments, and truthfully summarize the experimental process and innovative achievements. Experiments are the basis of writing experimental papers. As an independent form of practice, scientific experiment consists of experimenters, experimental objects and experimental means. The purpose of scientific experiment is to test a scientific theory or hypothesis and deepen the understanding of an objective thing. Therefore, scientific experiment is the foundation and forerunner of establishing scientific theory. The history of world scientific development has proved and will continue to prove that all major scientific discoveries and technological inventions are developed and refined from experiments; Scientific hypothesis can only be verified and tested through scientific experiments. Therefore, the discovery of scientific truth depends on experiments, and the test of scientific truth cannot be separated from experiments.
