网页第二、对开关电路的影响： 以上所有时间参数都会对开关电路的响应速度、最大工作频率造成影响，所有的参数都是要求尽可能小。. 如果是工作频率在MHz以下的电子电路，基本不需要讨论这些参数问题，时间参数主要是针对如计算机等高频电路（频率一般在百 ...
关于三极管的存储时间(storage time) 的讨论 - 电源网
网页2003年9月19日 · 存储时间对应三极管接收到关断信号到集电极电流下降到90%的时间间隔,也是饱和导通时基区的超量存储电荷的消散时间.因此和导通时的饱和深度大有关系,同时也跟关断电压、dv/dt有关. 一时不能说的很全,建议看看有关器件的书籍. 0. 回复. LV.1. 3. 2003-09-20 16:36. 认真看一看浙大出版的晶体管原理. 此书详细论述了三极管的存储时间的构成. 0. 回复. gwwater. LV.6. 4. 2003-09-22 00:44. @ 认真看一看浙大出版的晶体管原理此书详细论述 …

What is an Average Storage Time? - DHL Freight Connections
网页2024年9月13日 · What is an Average Storage Time? The average duration of storage provides information about the storage situation. In concrete terms, it describes the period that inventories and capital are tied up in the warehouse on average. At the same time, the average storage period also shows how many consumption periods an average stock cover.
网页The storage time of an optical cavity is defined as the time taken for the cavity field to decay by 1=e. For a cavity of length L cavity and finesse F (see (6)), the storage time can be written as t storage = 2L cavity F pc = p f FSR; (1) where f FSR = c=(2L cavity) is the cavity free-spectral-range. The storage time is therefore di-
