在实验科学高度发展的今天,人们对各类实验及其设计技巧进行了大量的研究,得到了不少有益的启示。然而,从整体上探讨实验设计的原则,至今却没有一致的结论。实验的成败如何,固然由许多因素决定,但人们普遍认为,实验设计必须在一定的原则下进行,因此,认识并把握实验设计的原则,对于正确地进行实验设计,保证实验的成功,有着重要的意义。本文就实验设计一般原则进行一些探讨。 In today’s highly developed experimental science, people conducted a great deal of research on various experiments and their design skills, and obtained many useful enlightenments. However, there is no consistent conclusion so far on the principles of experimental design as a whole. Although the success or failure of an experiment is determined by many factors, it is generally accepted that the experimental design must be conducted under certain principles. Therefore, understanding and grasping the principles of experimental design is very important for the correct experimental design and the successful experimentation Meaning. This article discusses some general principles of experimental design.
