The power spectrum adopted in this paper, which covers not only the travelling wave effect, but also the spatial coherence of the seismic ground motion, has general representation. 采用的非平稳随机地震动功率谱模型是根据多次地震动记录提出的,既考虑了多点激励的行波效应,又考虑了地震动的空间相干性,具有广泛的代表意义。
Quantum ground state approximation theory in determinant representation 量子基态行列式表示的逼近理论
The vibration spectra of two special patterns for H2S ground electronic state were studied by using discrete variable representation ( DVR ) scheme. 用离散变量表示(DVR)方案研究了H2S基电子态两种特殊振动模式的振动谱。
In order to validate the feasibility of the coordinate algorithm, the vibrational spectra of two special patterns for H2O ground electronic state were investigated in using discrete variable representation ( DVR ) scheme in mass-weighted coordinates and received the similar results in using other arithmetics. 为了验证质量加权坐标系算法的可行性,用离散变量表示(DVR)方法研究了H2O基电子态两种特殊振动模式的振动光谱,得到了与其他计算方法相近的结果。
