本文首先叙述了交叉活节的含义,并将其分为三类:(1)弹性交叉活节;(2)-1交叉活节;(3)几何交叉活节。并简略介绍了前人存交叉活节理论方百的成果。但是从目前资料未发现-1活节的计祘式,我国各研制单位都俈实验解决。本文在第三部分推导出了-1活节的一般计祘式。根据所导出的公式进行-1活节的设计,不仅可解决目前俈实验获得-1摆的麻烦,可缩短设计时间,又可少花钱;而且对于分析生产中的问题有理论指导意义。本文所导出的公式对于发展我国自动安平水准仪是有现实意义的。
This paper first describes the meaning of cross-section, and is divided into three categories: (1) flexible cross-section; (2) -1 cross-joint; (3) geometric cross-joint. And briefly introduced the achievements of the former theory of cross-living theory. However, from the current information is not found -1 live count formula, our research units are all 俈 experimental solution. In the third part of the paper, we deduce the general formula of -1 activity. According to the derived formula-1 activity design, not only can solve the problem of the current-1 pendulum experiment, shorten the design time, but also less expensive; but also for the analysis of production problems have theoretical significance. The formula derived in this paper is of practical significance for the development of our country’s automatic Anping level.
