查询词典 kilometer wave

There are four types of waveforms, increased sawtooth, square wave, triangle wave, sine wave.

Some one disagree our viewpoint, so at last we clarified that why this term vanishes identically when one rigorously studies the intrinsic magnetic moment of a particle, either fundamental or composite even we have chosen wave packets instead of plane wave, i.e. a superposition of physical plane-wave states, because they are strictly physical and practical.

因此我们的工作就是澄清了为什么当我们粗略研究一个粒子(不管这个粒子是基本的，还是复合的)的内禀磁矩的时候，我们是可以忽略掉这一项的，即使我们考虑波包而不是平面波，因为实际世界中我们遇到的更多是波包。

The result shows that gravity wave excited by the tropopause forcing can propagate stably to the mesosphere through the stratosphere so that the energy and momentum can be transferred from a region to another. In the propagation, gravity wave undergoes growth, overturning, convection and breaking. The breaking of gravity wave is the important source of convection and smallscale waves, and convective instability and overturn are the character of nonlinear phenomenon.

分析结果表明，从对流层顶激发的重力波能稳定地经平流层传到中层顶，从而将能量和动量从一个区域带到另一个区域；在向上传播过程中，重力波经历了发展、位温翻转、对流直至最终破碎的演变；重力波的破碎是对流和小尺度波动的重要的源，对流不稳定和翻转是非线性现象的一个基本特征。

According to the features of traveling-wave fault location,this paper describes the double terminal traveling-wave fault location method which based on the wavelet modulus maxima theory and application and realization of HVDC transmission line traveling-wave fault location.

根据行波定位的特点，介绍了一种基于小波模极大值理论的双端行波故障定位的方法，以及这种方法在HVDC输电线路行波故障定位中的应用和实现方案。

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。

4Until now, the best images of the surface derived from mapping missions have spotted objects as small as 1 kilometer across. This map picks up objects as small as 20 meters across or about the size of a large yacht.

迄今为止月球表面最好的图像能够分辨清直径大于1公里的物体，而这个图片能够分辨清20米的物体-仅相当于一个游艇的大小。

Basing on the mechanism of errors in levelling, a rigorous formula is first de- rived for calculating the mean accidental error per kilometer η.

由于σ在目前的一般水准测量作业中还是不能确定的，所以研究j在各种不同情况下略去σ定权，对平差质量所产生的影响。
