脈沖衰減率 的英文怎麼說
中文拼音 [màichōngshuāijiǎnlǜ]
脈沖衰減率
英文
rate of pulse decay-
Measurement of the tissue thermal conductivity by thermal pulse - decay method
生物組織熱導率的脈沖衰減法測量When the energy converters and the thickness of the steel plate are settled, the attenuation speed of the repetitious pulse reflected wave from the underside is only related to the reflectivity of the reinforced concrete interface
在鋼板厚度和換能器確定的情況下，多次脈沖底面反射波的衰減速度只與鋼-混凝土界面的反射率有關。The compensator was h ( s ) = 2370s. the results of simulation showed that attenuation factor of the first order of the third control system was as much as ten times of the value of the system without controller
通過模擬表明，採用速率傳感器，在前三塊帆板上布置壓電驅動器時，一階最大衰減因子為無控時的10倍，可以使脈沖衰減時間縮短15倍。It was the result from that the width of spectrum of the input em pulse packet was too wide, the spectrum included rather strong frequencies being above the cut - off frequency which have not been decayed
分析認為，這是由於輸入電磁波包脈沖的頻譜太寬，存在較強的高於截止頻率的頻率，這部分頻率未被衰減而直接傳輸所致。Practical implementations of quantum key distribution systems use attenuated laser pulses as the signal source rather than single photons. the channels used to transmit are lossy. on the basis of above two points, a combining eavesdropping strategy of intercept - resend and beam - splitting is discussed in terms of eavesdropper ' s technology requirement and detection efficiency and dark count of single - photon counter
主要工作包括以下三部分：一、基於實際量子密鑰分配（ qkd ）系統中所使用的強衰減的激光脈沖不是單光子，量子密鑰分配的通道不是無損耗的，光子計數器存在探測效率和暗計數以及竊聽者的技術能力也不是無限的這些具體問題。分享友人
