查询词典 linear switching

In chapter two, we first consider the linear system WAWx=b, where A is an m*n rank-deficient matrix. Then we consider the weighted Frobenius norm on data, and get the formula of W-weighted Drazin inverse solution of the linear system.

第二章的前半部分介绍了线性系统 WAWx=b 的加 W 权的 Drazin 逆解在范数带参数的 Frobenius 范数意义下的条件数，这里矩阵 A 为一个 m*n 的秩亏阵。

In the case that there is no a priori knowledge of the upper bound and lower bound of the unknown parameters, the switching adaptive control design approach is presented.

The basicflows are computed by a low-dimensional Galerkin method.The results confirm thattwo times global mode switching occur with increasing Re up to which the Hopf bifur-cation occurs when the absolutely unstable region cover the whole reversed flow region,and the first explanation of this phenomenon with absolute/convective instability theoryis given.

结果证实了只有当绝对不稳定性区域完全覆盖了回流区才会形成整体的Hopf分叉，此前随着Re数的增加整体模态经历了两次跳跃；并首次用绝对/对流不稳定性理论解释了这一现象。

The empirical study on the "state-share paradox" finds evidence in two dimensions. First, a regime-switching model with an absorbing state suggests that government policy switches the regime to liquidity black holes.

一个具有吸收态的状态转化模型表明国有股减持政策诱使股市状态转向所谓的"流动性黑洞"；同时，在股市行情大跌时追逐流动性的假说没有足够证据支持，因而股市大跌是整个市场的宏观现象。

Taking into account the absorption of Cr 4+∶YAG in excitaion state,the Q switching rate equations are given and the equations are solved numerically by using computer.

在考虑Cr4＋∶YAG激发态吸收的情况下，给出调Q 速率方程组，并且利用计算机对该方程组进行数值求解。

Once ISDN is fully implemented,however,today's disparate transmission and switching services will be accessible internationally via a single set of interface standards.

不过，一旦ISDN完全实现，则通过一组单一接口标准可以实现当今国际间异类传输和交换业务。

To ensure the continuity of the states of the SLS systems,for a given switching sequence an admissible control set is introduced.

对给定的切换序列定义了容许控制集合，以保证在该容许控制集合中的任意控制律的作用下，相应切换系统的状态都是连续的。

Taking the autobus of city as the researchable object,for the characteristic of run and power,the basic design parameter of the hydraulic system was studied.Based on much aspect of factor,for example,the cost and benefit,the power and security,hydraulic switching system of inertia as being used the pump/motor and the container of air sac type as the representative characteristic was designed.And the e...

以城市公交汽车为研究对象，根据其运行特点及动力特性拟定液压系统的基础设计参数，在综合分析了成本与效益，动力性与安全性等多方面因素的前提下，设计了以气囊式蓄能器及泵/马达一体部件应用为典型特征的惯性能量液压转换系统，实验证明该系统具有结构紧凑、反应迅速、节油效果显著的特点。

After switching the air-con on for about 1hr and a half, my work was done and I immediately came back to embrace my small fan again.

吹了一个多小时，把工作也赶完了。

This thesis discusses mainly the hardware design and development of a simulator for airborn phase array radar. The long period of the simulator is implemented by SDRAM MODULES used in Personal Computer, the broadband is implemented by D/A with internal double-data-channel switching architecture, and the control is implemented by a single CPLD.

本文主要探讨了一种机载相控阵雷达回波模拟器的硬件设计和工程实现，采用了PC机内存常用的超大容量高速缓存SDRAM MODULES来实现输出信号的长周期，采用内部具有双路数据分时切换结构的D/A实现输出信号的宽带，采用一片CPLD完成整个系统的时序逻辑控制。
