5.Each time the command processor loads an external command into memory, it places the contents of the file with an EXE or COM extension into the transient portion of the command processor and available memory.
每当命令处理程序把一个命令装入存储器时,它就把带有扩展名EXE或COM的文件的内容装入命令处理程序的暂驻部分。 Each time you invoke a command, DOS first examines its list of internal commands, if the command is found in memory, DOS executes it, Otherwise, DOS assumes it is an external command.收藏指正
6.Since DISKCOPY is an external DOS command, the search will fail, so the command processor must search the current working directory for an EXE, COM, or BAT file with the file name DISKCOPY.
由于DISKCOPY是一个部DOS命令,查找将会失败。所以,命令处理程序必须在当前工作目录中找到具有文件名DISKCOPY的EXE、COM、或BAT文件。收藏指正

9.Abstract: The synchronization control scheme of mechanical sy stem with multi-motor drives is proposed,in which every induction motor is controlled to trace the same speed command by speed sensorless field-oriented control respectively.For every induction motor,a full-order estimator is established to identify rotor speed,stator and rotor resistance,and external load.The torque current of induction motor is calculated by using the estimated external load and PID speed controller.Computer simulations show the effectiveness of the proposed scheme.
文摘:本文提出通过磁场定向控制分别控制多个感应电动机跟踪同一个指令性速度的多机驱动机械系统的同步控制方案.通过建立全维转子状态估计器,辨识感应电动机的转子速度、定子和转子电阻、瞬时负载,根据负载辨识结果与速度PID控制器确定感应电动机的转矩电流,实现感应电动机的无速度传感器控制.计算机仿真结果表明了该控制方案的有效性.收藏指正
10.Forehand attack is a non-habitual action in table tennis playing.it is the most important skill of quick attack players and the key of table tennis teaching to the students majoring in higher physical education.To have a good command of forehand attack in very short time is an important subject in table tennis teaching and coaching.Compared with different results of teaching and coaching experiments,it is proved that the alternate teaching and coaching method combined with external factors in practice can help the students form the dynamic finalization,that the teaching and coaching method is very effective and can be used in table tennis theoretical teaching and practical coaching.
