暗电流特性 meaning in English

dark current characteristic

In this thesis we have analyzed some kinds of single photon detector and their advantage and disadvantage firstly . then , the key apparatus ( ingaas - apd ) and its characteristics have been studied . we have tested the apds of perkinelmer , oki and photon company , and got some useful parameters
其次，主要对量子通信用单光子探测器的核心器件? ? ingaas雪崩光电二极管( ingaas - apd )的暗电流特性、光电流、温度特性、雪崩特性等进行了研究，同时把飞通公司、 oki公司、 perkinelmer公司的apd进行了比较，分别得出了它们的特性参数，为研制实用的红外单光子探测器提供了重要的依据。
