计算表明这些频谱中存在一个与湍流外尺度、横截风速有确定关系的峰值频率。
Caleulation shows that there is a peak frequency in these spectrums and the frequency depends on turbulent outer scale and transversal wind.
北西向断裂规模较小，一般为一些横截北东向断裂的扭性断裂(马杏垣，1989)。
Antitheticly, the NW striking faults are smaller and commonly wrench faults to cut the NE striking faults (ma X y, 1989).
非双曲线型非线性系统同宿切面点和同宿横截点的存在，使得其时间序列的去噪或轨迹重影变得十分困难。
The presence of homoclinic tangencies and homoclinic intersection makes it difficult if not impossible, to denoise or shadow the trajectory of a non-hyperbolic nonlinear system.
环境也存在危险因素，不仅仅简单地以危险工的作这样明显的形式存在，同样也以被称为“新奇”的具有横截特征的形式存在。
Situations also present risk factors, not simply in the obvious form of dangerous jobs but also in the form of a cross-cutting feature described as "newness."
文中还证明了这一非横截交点恰好对应于静态分岔点即电压崩溃的临界点。文中结果对于防止电压崩溃、保证系统安全运行具有重要意义。
In the meantime, it is also proven that the non transversal intersection mentioned above exactly corresponds to the static bifurcation point, i. e. the critical point of voltage collapse.
