精神分裂症 详细释义 词典释义 abbr. 分组交换数据业务(Packet-Switched Data Service);（从服役单位）退伍;高级服务提供系统(premium services delivery system) 双语例句 1. Lateral-Effect PSDs are preferred in applications where continuous or fine displacements must be measured in real time. 侧向效应灵敏探测器最好应用在必须对连续或细微位移进行实时测量的情况下。 2. In contrast to segmented PSDs, Lateral-Effect PSDs are composed of a single active element in which the photodiode surface resistance is used to determine position. 与分段灵敏探测器相比，侧向效应灵敏探测器是由一个单一的活性元素构成，其中使用光电二极管的表面电阻来判断的位置。 3. The influences of load resistance on tetra-lateral position sensitive detectors ( PSDs) are studied by experiment. 通过实验研究了负载电阻对四边形PSD的影响规律。
