Finally, according to the rule of investigation of injury and death accident, we bring forward correspond measure by methods of artificial intelligence and Fault Tree Analysis, which make it an important and necessary part of MIS of injury and death accident.

最后，根据伤亡事故调查处理规则，利用人工智能技术的特点、方法，运用事故树的方法对具体的实例进行分析，通过对各个子事件重要度大小的不同，提出相应的预防措施，把它作为伤亡事故管理信息系统的一个重要的子模块和一个必不可少的有机组成部分。

Comparing radiocarbon readings with the natural time clock of the tree's year by year rings, showed the radiocarbon dating system to be inaccurate.

放射性污染与自然相的时钟树的逐年戒指、该系统将放射性碳测年结果不准确。

Thus, all the processes in the whole system belong to a single tree, with init at the root.

然而，在系统中的所有进程属于一个信号树，而init进程在最根部。

Using abstract programming language, such as Apia, the specification and derivation of the algorithmic program in six typical trees, graph problem is described. The standard proof and formal derivation is implemented by two above new strategies for developing loop invariants. The algorithm in Apia is transformed into corresponding program in Delphi and C++ by the automated algorithmic transformation system that Partition-and-Recur method provided and correct result is received. These improve reliability and developing efficiency of the kind of complex algorithm.

利用抽象程序设计语言Apla精确描述了6个典型树、图等问题的程序规约和求解算法程序，用上述提出的两种新策略开发了循环不变式，实现了严格的形式化推导或证明，并用PAR方法提供的算法程序自动转换系统将得到的Apla算法程序转换成对应的Delphi和C~程序，均得到了正确的运行结果，大幅度地提高了这类复杂算法程序的可靠性和开发效率。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
