Ground parts: an overhead-type indicator by sampling ground capacitance transient current in the first half-wave and ground transient voltage in the first half-wave, to compare their phase, when the sampling ground capacitance transient current mutation and more than a certain value, and the instantaneous voltage and grounding The first-phase half-wave, while wire-to-ground voltage is reduced, then the judge circuit grounding occurred.

接地部分：架空型指示器通过采样接地瞬间的电容电流首半波与接地瞬间的电压首半波，比较其相位，当采样接地瞬间的电容电流突变且大于一定数值，并且与接地瞬间的电压首半波同相，同时导线对地电压降低，则判断线路发生接地。

Gravity wave and ozone are two interesting topics in the middle and upper atmosphere. In this dissertation, they are studied by numerical simulation and instrument development respectively.In section one, by using FICE scheme and TIME-GCM, a model of trace gases and OH airglow affected by gravity wave is set up, then the propagation of nonlinear gravity wave and the effect on trace gases and OH airglow are analyzed. The result shows gravity wave excited by tropospause forcing can propagate stably to the mesosphere through the stratosphere so that energy and momentum can be transferred from one region to another. In this process, gravity wave undergoes growth, overturning, convection and breaking. And the no-isothermal structure can accelerate the breaking of gravity wave in mesospause, and the breaking of gravity wave is an important source of convection and small-scale waves.

By means of relevant methods and theorems in the qualitative theory of differential equations, traveling wave solution of a compound Burgers-Korteweg-de Vries equation is studied.

利用微分方程定性理论的相关方法和定理，对一类复合Burgers-Korteweg-de Vries方程进行研究，获得了方程行波解的存在性和唯一性，并给出了方程行波解的表达式，与此同时，研究了行波解的动力学行为和它们不同解的分岔。

Brian Pritchard plausibly suggests that Caldara's 1712 commission of Vaticini di Pace 12 for Ruspoli which was performed in the Palazzo Bonelli in imitation of papal tradition assisted Caldara in securing the 1713 commission and that additionally Ruspoli in choosing Paolo Gini's text for Vaticini di Pace was attempting to heal the longstanding rift between Pope Clement XI and Charles VI, the Pope having withheld papal recognition of Charles VI as Holy Roman Emperor and Defender of the Faith.

There is a clear correlation between seismic activity and Pn velocity variation. Most earthquakes are concentrated in the northcentral Tien Shan with high Pn velocities, while almost no earthquakes located in the southcentral Tien Shan with very low Pn velocities.

Pn波速度的变化与地震分布有着密切的对应关系：地震大都发生在中天山北部Pn波高速区上方，而南部的Pn波低速区上方几乎没有地震。

He was therefore unpopular in mainly Calvinist Bohemia, whose rejection of Ferdinand launched the Thirty Years' War, which can be divided into four major phases: the Bohemian Revolt, Danish intervention, Swedish intervention, and the French intervention.

他由此在以开尔文教派为主的波西米亚极不受欢迎。而波西米亚人拒绝斐迪南二世成为其国王导致了德意志三十年战争。这场战争可以分为四个主要时期：波西米亚人的起义，丹麦的介入，瑞典的介入，和法国的介入。
