This paper put forward a new type backstop that transfer the backstop moment by the meshing components , and completed the design of the backstop 本文提出了一种新型的由啮合元件传递逆止力矩的啮合式非接触逆止器，并完成了逆止器的设计。
The paper analyzed the external forces of the backstop , established the dynamics model of the backstop being run , and analyzed the dynamic load of the backstop 分析了逆止器的受力情况，建立了逆止器工作的动力学模型并对逆止器进行动载荷分析。
This is a significant change from the . net framework versions 1 . 0 and 1 . 1 , which provide a backstop for many unhandled exceptions for example , unhandled exceptions in thread pool threads 这是对. net framework 1 . 0和1 . 1版的重要更改，这两个版本对许多未处理异常（例如，线程池线程中的未处理异常）提供支撑。
And the paper analyzed the relations between the errors of the components and load distribution among the backstop piece , and put forward a method of translating the errors into a equivalent error . for the occasion of several backstops being used at the same time , the paper put forward a project of uniform load among the backstops 分析了误差对逆止器内部逆止块的载荷分布的影响，并提出各种误差转化为等效误差的方法；对多个逆止器同时使用的场合，提出了均载方案。
