Study On The Simple Of The Science Theory System

In the science history, the theory about natural science is reflection that human being understand the natural world. Not only the theory describe the natural world's things and phenomena, but also see through the appearance to the essence. Along with the increase of nature's knowledge, the level of science theory are developing and improving. The most common theory and fundamentals about science are the simplest in form. Because they have summary and simple forms, the science theory are able to effect science's creating and developing in a long time. Before all others, the dissertation analyzed the meaning of "simple", and put forward that "simple"is depend on the subject's understanding, it is appraisal concept, but not a truth concept, so it has subject. Analyzing the origin of "simple", we know that "simple"accompany with the expanding of science and knowledge's growing. But it brings some limits. We must investigate the advantage and disadvantage of "simple", and exactly understand the meaning of "simple". On these bases, the dissertation analyzed the criterion about the science theory system. Linking with model cases analysis on astronomy, we will bring up the overall meaning of "simple"in science theory system, which includes three aspects: the harmony that exists in natural world exactly is the base; the premise is the simple form about theory system; the assurance is the economical thinking during the theory's creating process. And put forward that how to judge the simple of science theory system is depend on not only subjective and objective principles, but also logical and history principles. Only combining with these, we can judge the simple of science theory system. Last, in the light of criteria, and linking with the process, we studied the reality affect in deeply, and put forward the simple is very important for the science theory system.
