(一) 二十多年来,国际上设计方法学的研究十分活跃,研究报告和专门著述,可谓洋洋大观。归纳起来,可分为下列几个主要流派。 1.注重程序的设计方法派。这一流派的主要特点是:首先根据任务的总要求,将总功能分解成基本动作和单元功能,然后将每个单元功能找出物理效应和解法,根据功能之间的逻辑关系构成功能矩阵,从而得出多种解。随后,再根据总功能和经济 (I) For more than 20 years, the research on design methodology in the world has been very active. The research reports and specialized writings are very impressive. To sum up, can be divided into the following major schools. 1. Focus on the design method of the program. The main features of this genre are: First, according to the general requirements of the task, the general function is decomposed into basic actions and unit functions, and then the physical functions and solutions of each unit function are found out, and the function matrix is ​​formed according to the logical relationship between functions. Which leads to a variety of solutions. Then, based on the total function and economy
