查询词典 switched

These Lorenz systems are built, which are relevant and can be switched each other via the choicer. Chaotic synchronization of these systems is realized using same nonlinear feedback control method. The transmitter can be switched discretionarily among several chaotic systems, bring on ceaseless changing of the chaotic carriers in transport channel. In the receiver, the chaotic carriers are retrieved from the received signals, then the information signals are recovered.

构建了有一定关联的两个Lorenz混沌系统，并通过选择器在系统间随机切换；用同一种控制方法既能实现不同Lorenz系统的混沌同步，又能实现相同Lorenz系统的混沌同步；发送系统可以在Lorenz混沌系统间随机转换，传输信道中混沌调制信号也随之不断变化；接收系统将混沌调制信号解调后，即可获取有用信号。

When compensating devices are switched by vacuum switches, if they are switched on group, the inrush current can be controlled by inserting suitable current-restrained reactance in-series. Since the restriking overvoltage is pertinent to the capacity of compensating devices and the time of restriking and igniting, the overvoltage can be restrained by arresters with asterism connection at the entrance of the capacitors. Although switching capacitance devices will bring up high interception cross overvoltage, the metal-oxide arrester can limit this overvoltage in the system designed in the thesis, and naturally the compensating devices can operate normally.

使用真空开关投切并联无功补偿装置，在分组投入并联电容器时，串联合适的限流电抗，合闸涌流可以得到控制；重燃时的过电压值与并补装置补偿容量，重燃发生时刻和燃弧时间有关，电容器进线端的三星接法避雷器可以抑制其过电压；切并联电抗器时会产生较高的截流过电压，金属氧化物避雷器可以使本文中所建系统的截流过电压得到限制，并联无功补偿装置可以正常切合。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
