In order to investigate the variation of controllability and observability affected by network scheduling,the model of scheduling for Networked Control System is established,which has communication constraint on its input and output channel.Utilizing communication sequence to express the scheduling of channel,the model can be transformed into discrete-time switch system.Under static scheduling,using the theory of recursive invariant subspace and its character,a necessary and sufficient condition of NC...

为了研究网络调度对能控性与能观性的影响，对输入、输出通道都存在通信约束的网络控制系统的调度进行建模；利用通信序列表示通道的调度情况，最终将模型转化为离散切换系统；在静态调度下，利用循环不变子空间理论及其相关的性质，给出了网络控制系统能控性、能观性成立的充要条件，并给出了原有控制系统与经网络静态调度后的系统之间能控性、能观性的关系；最后用仿真实例说明了所提结论的正确性。

In the system of high precision and low speed, Because of the existence of the nonlinear friction, the static and dynamic performance of the servo system is very bad, such as stick slip, hunting, large error and so on, Because the traditional control of PID is hard to solve the nonlinear problem of the servo system, so this paper begins to introduce a new control method which is named adaptive fuzzy PID, It utilizes the rule of the fuzzy control to adjust the parameter of proportion, integral and differential on line, So this control method has some intelligence to improve the static and dynamic performance of the servo system.

在高精度、超低速伺服系统中，由于非线性摩擦环节的存在，使系统的动态及静态性能受到很大程度的影响，主要表现为低速时出现爬行现象，稳态时有较大的静差或出现极限环振荡；由于传统的PID 控制很难解决伺服系统中的非线性问题，因而不能适用于高精度、超低速伺服系统；本文通过引入模糊自适应整定PID控制，利用模糊规则在线调整比例、积分、微分环节，使系统具有一定的智能，从而非常明显的改善伺服系统的静态及动态性能。

It is shown that deformation temperature is the main factor that influences the static recrystallization behavior. Carbonitride precipitation inhibits recrystallization and causes a plateau in the softening ratio curve. The static recrystallization activation energy of X80 pipeline steel was regressed and calculated to be 380 kJmol^(-1), and its rationality was also discussed according to previous references and investigations.

结果表明：变形温度是影响奥氏体静态再结晶行为的主要因素；微合金碳氮化物的析出抑制了再结晶的进行，使软化率曲线出现了平台；利用实验结果回归计算出了X80管线钢的静态再结晶激活能为380kJmol^(-1)，并根据文献研究讨论了结果的合理性。

Looking like discovers that many friends can not also peg out static state and false static state very accurately.

貌似发现不少朋友还不能很准确的分清静态和伪静态。

The test results were analyzed and compared with results of other researchers. The different responses between tantalum plate and tantalum bar were analyzed. A simple discuss of plastic deformation mechanism for tantalum was given too.

最后一章利用常温下的动态、准静态应力-应变实验数据和准静态下的高低温实验数据分别确定了钽的Johnson-Cook和Zerilli-Armstrong形式的本构关系，发现拟合结果与实验值并不能得到较好的吻合。

The study and comprehensive analysis of static high-pressure quenching experiments and laboratory dynamic high-pressure experiments on chondrites,as well as the study of shock-induced phase transition of minerals in the Suizhou meteorite revealed that the P-T conditions for phase transition of minerals during natural impact events,such as collision of cosmic bodies or impact of meteorites on the Earth′s surface,are not consistent with those obtained by shock experiments on chondrites or rocks in laboratory,...

通过对球粒陨石的静态高压淬火实验和人工动态高压实验的研究和综合分析，以及对在太空中经受过撞击的随州陨石中矿物发生高压相变的研究，查明了自然界的冲击事件，如星体的相互碰撞和陨石对地球表面的撞击中，矿物发生相变的P-T条件与人工冲击波实验的结果并不一致，而与静态高压淬火实验的结果相似，即前者类似静态高压淬火实验，保压时间较长，能产生高压矿物，后者保压时间极短，无高压矿物形成。

The exchange and adsorption properties of LA, FA and glu on six anion exchange resins were investigated, and the influence of the temperature was also researched, among them weakly basic ion-exchange resin 335 can provide the highest uptake capacity of LA The Freundlich equation can explain the adsorption equilibrium curves of LA on the anion resins better than the Langmuir equation.

Based on the analyses and research for the CO〓 welding system with constant wire feed rate, a unified mathematics model, which not only describes the dynamic process around the static operating point but also describes the static relations, is set up.

通过对CO〓焊等速送丝系统进行分析和研究，建立了一种在静态工作点附近既能描述CO〓焊等速送丝系统动态变化过程，又能描述静态关系的统一模型。

There can be no static members of a local class. Local class members may not access the local variables defined in the enclosing function. They may use type names, static variables, or enumerators defined in the enclosing function.

局部类不能有静态成员，局部类成员不能访问外围函数中定义的局部变量，它们可以使用外围函数中定义的类型名、静态变量和枚举成员。

Plunder melds and run with this jewel!
