In chapter 1, based on the technology of block matrices and the properties of block diagonal dominances, new results are obtained for the lower bounds of the smallest singular value.

第一章主要通过矩阵的分块和块对角占优性来讨论了最小奇异值的下界。

The work is to be carried out with the least-possible burden on production operations and will be performed during customary maintenance downtimes.

这项工作将被以生产运作最小负担值运行并且将在习惯性的维修停机时间工作运转。

Firstly, aiming at the problems existed in former models, with isotropic elastic damage exampled, based on strain equivalent principle, a novel failure process model is developed and formula for calculating rock failure critical value is also presented.

首先，针对前人模型存在的题目，以岩石的各向同性弹性损伤为例，根据最小耗能原理在应变等效原理条件下提出了一种新的损伤演变模型，克服以上模型存在的题目，同时也给出了岩石损伤临界值的计算公式，并对三向应力作用下做了简单的探讨。

After 10h ball milling, the alloy of carbonyl iron and carbonyl nickel began to form, and the sample kept its original bcc and fcc structure; after 100h ball milling, the sample became a solid solution with bcc structure; after 200h ball milling, the diffraction peak of Ni almost disappeared and the isotropic grains with D achieved, which was mainly attributed to the dislocations and disclinations of the nanocrystalline bcc FeNi suffering from severe plastic deformation by ball milling.

球磨10h时，羰基铁和羰基镍开始形成合金，但大部分Fe、Ni原子仍分别以bcc结构和fcc结构存在。球磨100h时，样品以bcc结构的FeNi合金为主，球磨200h后，样品中fcc结构Ni特征峰几乎消失，FeNi纳米晶达到最小粒径的平衡值，~8nm。高能球磨过程中，晶界区域的层错缺陷是合金化和纳米晶形成的重要因素。

The minimum ground clearance of bundle conductors for 1 000 kV AC UHV transmission lines is one of the key factors in UHV transmission line design.

导线最小对地距离的取值是特高压输电线路设计过程中需要考虑的关键因素之一。

The ground side of the capacitor should be connected into the ground plane with minimal lead- or trace length.

最好从0.01mF最小电容值开始放置，并且靠近放置一个2.2mF的具有低等效串联电阻的电解电容器。

First index system for evaluation of electricity customers' credit is established. The index and the subjective experience value of valuators are given in the form of triangular fuzzy number. Then expected values were resulted by fuzzy decision making method based on expected value. Finally, structure risk minimization principle modifies the expected values.

建立了电力客户信用评价指标体系，并以三角模糊数的形式给出指标值和评价者的主观经验值，利用模糊期望值决策法得到信用期望值，最后通过SVM基于结构风险最小化原则修正该期望值。

That there exists a fixed number I such that for any , there exists a such that if the length of the longest diameter of those subregions in a partition of D is less than , then

假设存在一个确定的数满足：任给，存在，使得当各小区域的直径中的最大值小于时，就有

N algorithm for close approach determination was developed by Alfano and Negron （1993） based on polynomial splining techniques.

lfano—Negron（1993）提出的空间目标接近分析算法将最小相对距离及其对应时刻和进出误差椭球时刻的求解问题均转化为插值多项式求根问题。A—N算法在判断三次多项式根的存在性、筛选合理实根时存在缺陷，可能导致多余计算。

The allele E of ADL252 had a significantly positive correlation with EW,and the allele C of ADL252 had a significantly negative correlation with egg weight at first egg in Silkies.

标记G01672基因型为EE、AE所对应开产蛋重最小二乘均值与基因型为CE、CC的对应值间差异显著；等位基因E与开产蛋重有显著正相关，等位基因C与开产蛋重有显著负相关。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
