The cheapest way to get one is to invoke the spectral theorem and to conclude that normal operators always have non-trivial invariant subspaces.

取得这样结果的最省力的尝试是引用光谱定理而得到正规算子恒有非平凡不变子空间的结论。

The acceptability of blue jeans and denim cloth clothing varies — some businesses disallow them as sloppy, not casual, yet tolerate men wearing blue jeans with a sports coat .

蓝色牛仔裤和牛仔布料的衣服可接受的程度不一样－有些商业场合认为这是不正规的穿着，不是休闲类的服装，然而许可男士穿蓝色牛仔裤配运动类上衣。

Aimed at the problem of choosing the initial value when the Newton method is used to compute the controlling unstable equilibrium point, a practical and rigorous solving scheme was presented: by identifying the controlling load bus of the given fault, and using the Thevenin equivalent circuit to represent the rest of the system at the state of the post disturbance stable equilibrium point, using the steady equivalent circuit to represent the induction motor in composite load, and then using the torque characteristics of induction motor, a point near the CUEP is gained to be the initial value. The second order normal forms was used to approximate the stable manifold of CUEP, and the local approximating boundary of the region of attraction of the post disturbance stable equilibrium point was gained. Then just by simulating the state of the system at the fault clearing time, the transient voltage stability of the system could be determined.

针对采用牛顿法求取故障后系统主导不稳定平衡点(controlling unstable equilibrium point，CUEP)存在的初值选取难题，提出一种实用但不失严谨的解决方案：通过识别给定故障的主导负荷母线，对主导负荷母线以外系统由故障后稳定平衡点处的状态进行戴维南等值，对负荷中感应电动机部分采用其稳态等值电路，再由感应电动机的转矩特性求得CUEP附近的一个点作为近似的CUEP，以此为迭代初值可靠求得CUEP；采用二阶正规型来近似CUEP的稳定流形的方法求得近似的局部吸引域边界；由仿真得到故障清除时刻系统的状态并根据该状态是否位于吸引域内判断系统的暂态电压稳定性。

The integration time at normal state is determined by value of pull-up register and stray capacitance on the port and electrode.

Now the third stage began with the concentration of regulars into larger groups with the intention of building up a sizable striking force .

当前的第三阶段，则是以正规部队化零为整开始，旨在建立一支强大的战斗部队。

In this paper we try to use c-normal condition on minimal subgroups to to characterizethe structure of G.

在本文中，我们用极小子群的c-正规的条件刻划群G的结构。

The fourth chapter points out at first five defects in Chinese legislative practice, i.e., the form of legal validity is not standard; terms of effective date are confused; the clause stipulating effective date is missing; the form of immediately effective is used too much; the subheading of law is inconsistent with the terms of effective date in the main body of law.

正文第四章首先提出了在我国立法实践中出现的五个问题：法的生效形式不正规；法的生效日用语混乱；法的生效日条款的缺失；即时生效形式使用过多；法的副标题与正文法的生效日用词不一致。

Where HSG is the maximal subnormal subgroup of G which is contained in H.

其中HSG表示G包含在H中的最大的次正规子群。

In this paper, we replace the N normality with N subnormality in c-normal concept to get the weak c-concept.

推广了[1]中的定理3.5得到一个有限群G可解当且仅当每个在F~中的极大子群弱c-正规。

Process expression of a Petri net is a regular expression with the basic subprocess set of the net system as alphabet.

要把进程表达式的概念推广到无界Petri网，会遇到两方面的困难。一方面，由于正规表达式的字母表必须是一个有限字符集，是否可以把一个无界Petri网的各种可能的运行情况都归结为有限个基本子进程的组装？
