Type I-3 and Ⅱ-6 dynamic compliant wrists have been designed and made. Prblems in the production of compliant elements and the connection between compliant elements and wrists were also solved. A study on the results of tests of the function of two kinds of dynamic compliant wrists shows that the dynamic compliant wrist's compliancy function can be improved by adding metallic materials having higher longitudinal and transverse rigidity into the softer elstomer. And the design Principle is proved to be feasible and practicable. It can be expected that the use of dynamic compliant wrist will greatly lower the technical requirements of the shaft-hole assembly and the requirements in the resetting accuracy.展开更多

So instead of Carnap, in this paper, I devote myself to its necessary and sufficient commentary. In the beginning part （Sections 2-5）, I explain why Carnap began the study of inductive logic and bow he related it with our thought on probability （Sections 2-4）. Therein, I trace Carnap＇s thought back to Wittgenstein＇s Tractatus as well （Section 5）. In the succeeding sections, I attempt the simplest exhibition of Carnap＇s earlier system, where his original thought was thoroughly provided. For this purpose, minor concepts to which researchers have not paid attention are highlighted, for example, m-function （Section 8）, in-correlation （Section 10）, C-correlate （Section 10）, statistical distribution （Section 12）, and fitting sequence （Section 17）. The climax of this paper is the proof of theorem （56）. Through this theorem, we will be able to overview Carnap＇s whole system.展开更多
