直接切换

特别是大功率电机，直接切换会产生极大的危险性，对电机、电控设备和电网都会产生很大的冲击和破坏。

Especially for high-power motor , direct switching would create a great impact even danger on motor , electrical control equipment , power network .

如果要对数字电视信号进行直接切换，将涉及到信号的包完整性、复用流中包识别和不同编码帧的处理等一系列问题。

DTV signal can be switched directly , which is related to the integrity of packets , the definition of packets in multiplex streams and measures among different frames .

基于变结构控制的气动力/直接力切换控制设计

Aerodynamic / Reaction-jet Switching-controller Design Based on Variable Structure Control

它既可以具有直接的切换功能，也可以具有自锁切换功能。

It can not only be of direct switching function , but self-locking switching function .

与传统的动态定价模型以价格集合作为模型变量不同，本文所建立的模型直接以不同价格切换的时间点作为决策变量，使期望收益与价格决策的函数关系更加清晰。

Different from the traditional dynamic pricing models which take price set as decision variables , this model directly take time threshold point of price change as a decision-making variables to express the relationship of price decision and value function more clearly .
