Accidence discuss of water hunting by using half decay time method on island tundra 冻土带上半衰时找水初探
Tone pulse decay time 单音脉冲下降时间
Chapter two introduces the theory of optical cavity decay time method 第二章介绍了时间衰减法测量无源谐振腔总损耗的原理。
Absorption decay time 吸收衰减时间
Pulse decay time 脉冲衰减时间
The decay time of the crystal grown in our lab reaches advanced international level 衰减时间及快慢成分比例达到国际先进水平,在国内属于首次报道。
The luminous intensity of phosphor - powder synthesized by this method is 32mcd / m2 after the sample was excitated 300s , and the decay time of the sample is 350min 该法制备出的发光粉激发后300s时的余辉强度32mcd m ~ 2 ,测量余辉时间为350min 。
The presumably arise from small changes in either of the two processes , which give the dynamo action , or both , decay time for the main dipole part of the geomagnetic 这种变化当是起因于能产生发电机活动的这两个过程之一。或者是两个过程中的小变化。
A fitting curve between the decay time constant and the film thickness of ybco was obtained , and the film thickness can be obtained from the fitting 另外还作出了ybco薄膜的薄膜厚度与衰减时间常量之间的关系曲线,提出了测量ybco薄膜厚度的一种新方法。
