一、 场的概念、标量场和矢量场 1。数学上引入场的概念，用于描述物理量在 空间的分布和变化规律。如果空间的每一点 都对应着某个物理量的确定值，就说在着空 间里确定了该物理量的场。 若该物理量是数量（标量）——标量场，如 温度场、密度场、电位场；若是矢量，这个 场为矢量场，如力场、速度场、电场、磁场、 引力场等

液压动力元件起着向系统提供动力源的作用,是系统不可缺少的核心元件。液压系统 是以液压泵作为系统提供一定的流量和压力的动力元件,液压泵将原动机(电动机或内燃机) 输出的机械能转换为工作液体的压力能,是一种能量转换装置

一、液压传动的定义 一部完整的机器由原动机部分、传动机构及控制部分、工作机部分(含辅助装置) 组成。原动机包括电动机、内燃机等。工作机即完成该机器之工作任务的直接工作部分, 如剪床的剪刀、车床的刀架等。由于原动机的功率和转速变化范围有限,为了适应工作 机的工作力和工作速度变化范围变化较宽,以及性能的要求,在原动机和工作机之间设 置了传动机构,其作用是把原动机输出功率经过变换后传递给工作机

一、判断下列说法是否正确,用“√”和“”表示判断结果填入空内。 (1)在N型半导体中如果掺入足够量的三价元素,可将其改型为P型半导体。()
