危急的

Upon completion of this course, the student should be able to: distinguish between reliability and safety and critically read accident reports, perform a hazard analysis on a computer-based system, write requirements for a safety-critical system and trace safety constraints to design, work with human factors experts in the design of safe human-computer interaction, apply the principles of safe design to both systems and software, critique and evaluate a system design for safety, and design a process for building a safety-critical system.

通过完成这门课程，学生能够：区别可靠性和安全性，精读意外事件报告，运行一个以电脑为基础的系统的危险分析，写出一个安全危急系统的必备条件，并通过追踪安全限制，与人类因素专家合作设计安全的人机交互，在系统和软体中应用安全设计理论，评估一个设计系统的安全性和设计一个建立安全危急系统的步骤。

At the end of today's proceedings, the adjournment of the House will be proposed until May 2l with provision for e

在这危急存亡之际，如果我今天没有向下院做长篇演说，我希望能够得到你们的宽恕。

Firstly, this thesis presented the theory of overspeed protection system. And pointed out the reason why the emergency stop system is often fails in stroke. And then use the theory of hydrodynamics and fluidics jet to solve the problem. The conclusions can be used to analyze the status of emergency stop system, which often acts early.

本文首先分析了该型超速保护的动作原理，指出该型危急保安器注油试验拒动的原因；首次利用流体力学的相关理论引入射流的概念，提出了改造方案，同时对该型危急保安器注油试验装置改造后飞环提前动作作出了理论分析。
