Technicians often have to do experiments, and each experiment may not be able to achieve the desired effect. Many technicians simply divide the experiment into success and failure, when achieving the effect is regarded as success, but not to achieve the effect is regarded as failure.

In fact, there is no difference between success and failure, and every experimental phenomenon reflects a causal relationship. It is a waste of resources to obtain the experimental data without performing effective analysis.

Whether the experimental result is "good" or "bad", try to use theory to analyze the causal relationship, thorough analysis, nature is a good result, can let you get a case (later must use); and when you find the known theory, cannot explain the results, the process, in fact, is the process of enriching knowledge. In the long run, knowledge will continue to grow, and the ability to analyze with theory will continue to improve.

Instead, in the face of an experimental results, just judge success or not, not to think about why, not to make in-depth theoretical analysis, so you get only fragmentary experience, even in an industry soak for a long time, also cannot get through meridians, at best is "many years of daughter-in-law boil into", in an industry, in a product, will be unable to adapt to.‍
