The investigation shows that data of tipper and apparent tipper obviously reflect the inhomogeneity of horizontal direction of medium-electric resistivity, particularly the fault. So the data of frequency range apparent tipper calculated by high-quality four-component observation data can be used in identifying the position, inclination and scale of fault.

研究结果表明：倾子和视倾子资料对介质电阻率水平方向的不均匀性，特别是对断裂反映明显；应用质量较好的四分量观测数据计算出高频段（频率大于1Hz）的视倾子资料，可以用来判断断裂的位置、倾向和规模。

You have had more than your share of this apple-pie.

Exemplified by northern Tarim area of Xinjiang,the paper has also illustrated the achievements gained in layering ,calculation of argillaceous material conten.

本文概述了主分量分析法PCA的基本原理和自编的分析程序流程，并以新疆塔北地区为例，说明了分层、计算泥质含量及孔隙度的成果。

Then, the sequence voltages of the slack bus is replaced, and finding the positive sequence power flow several times until convergence comes off. Compared with the three-phase Newton-Raphson method, the Jacobian matrix with the proposed algorithm is of much lower order. The computation of finding the negative sequence component from the coupling power is only division arithmetic.

本文算法中修正方程式的雅可比矩阵阶数同单相潮流算法相同，是传统三相潮流算法的1/3，而通过耦合功率求解负序分量的计算，仅仅是简单的除法运算，计算量远远小于高阶矩阵的处理，因而总体上，与传统方法相比，大大降低了计算量。

Even the infantrymen were exhausted to the limit. However, for us artillerymen, it was necessary to roll, carry, and drag our not-so-light guns by hand too, but nobody grumbled or whined.

甚至步兵在这样的行军过后也会疲惫不堪，更别说我们是炮兵了，要用双手推拉拖拽分量不轻的大炮，但是没有一个战士抱怨或者发牢骚。

First,the distance ratio between within-class and between-class of each column of mixing matrix is computed by using a distance measurement.Then,for each class,the mixing matrix and independent components are re aligned by sort ascending according to the distance rate,and the columns of the weight matrix with smaller distance ratio and the corresponding features are reserved.Finally,the best feature set is selected by genetic algorithm from these foregoing feature vectors.

首先，使用一种距离度量来计算混合矩阵每一类的类内类间距离比；然后对每一类按该比值由小到大重新排列混合矩阵和独立分量，保留权重矩阵中类间类内距离比大的列，及其对应的特征向量；最后对这些特征向量使用遗传算法选择最优特征组。

It is also continuously and augmentative for the own pressure and weight.
