wave-number vector

A three-dimensional vector, which consists of the β of bispectrum, Shannon entropy, and wave crest factor is the sensitive eigenvector for faulty insulator.

双谱幅值特征量β、波峰因子、Shannon熵组成的三维向量是绝缘子劣化的敏感特征向量。

The measurements of the radio spikes with high time and frequency resolution by the spectrometer in Beijing Observatory may provide a self consistent diagnosis for the ambient plasma parameters ( magnetic field, density, temperature, wave vector, and the properties of nonthermal electrons).

利用北京天文台高时间和高频率分辨率的射电频谱仪对射电尖峰的测量，可以对背景等离子体参数进行的自洽诊断（磁场，密度，温度，波矢，及非热电子的性质）。

By means of the dyadic Green's function technique and the principle of scattering superposition, the EM fields wre expressed in terms of spheroidal vector wave functios.

运用并矢格林函数和散射叠加原理，求解的电磁场表示为椭球矢波函数。

The results show that when the wave vector with parallel to the interface exceeds the damping constant and the field strength exceeds a certain threshold, the population of interfacial optical phonons grows with time.

研究结果表明：当平行于界面的波矢超过衰减常数，场强超过某一阈值时，界面光学声子数随时间指数增加。

The space scale of this nonlinear force which is called as binding force is determined by the imaginary part of the perturbed wave vector.

这个被称之为结合力的空间尺度是由扰动波矢的虚部决定的。
