In a caesium clock, the optimum frequency corresponds to 9,192,631,770 oscillations of the microwave per second (just over 9 GHz in frequency), so dividing the output electronically by this number provides one-second 'ticks' of the atomic clock.

对于铯原子钟，其最佳频率是微波每秒振动9，192，631，770次(频率略高于9 GHz)，而用电路把输出的信号除以这个数字就提供了原子钟的一声"滴答"。

In this paper, from two aspects of the total potential method and abnormal potential, three types of boundary conditions which affect calculating results in the finite element method are analyzed, and this provides a foundation for using the appropriate boundary conditions and selecting the best distance to enhance its accuracy.

本文从总电位法和异常电位法两个方面，分别就直流电法有限元中所采用的三类边界条件对计算结果的影响进行了分析，为采用合适的边界条件及选取最佳边界距离来提高正演精度提供了基础。

Systematically analysing the method on the failure approach of patten recognition of the flood control hydro-project system, combining the social economical efficiency of the flood control system"s invalidation losses, the paper provides the concept "flood disaster risk " and constitutes the failure analysis approach of patten recognition system on the base of the flood progress. Combining with the subsystem functions and the failure probabilistic analysis of the hydro structure, the paper discusses the main failure approach of patten recognition and calculus of failure probability, calculates flood control hydro-project"s total risk.
