Hans , whose primary responsibility as interrogator was to make a positive identification , knew them by heart : his height and weight , head circumference and shoe size , scars , detal work , a tattoo under his left arm listing blood type 汉斯作为问讯人，首要责任是确定他的身份，把他的所有特征都牢记在心：身高、体重、头围、鞋码、伤疤、牙医记录，以及左臂上表明血型的文身。
Did the young man recognize that face by the light of the lantern in his tilbury , or was he merely struck with the horrible appearance of his interrogator ? we cannot say ; but only relate the fact that he shuddered and stepped back suddenly 究竟是那青年人借着车灯的光已认出了那张脸呢，还是他只不过被那种可怕的样子吓了一跳，这一点，我们无法确认，我们只能把事实讲出来，只见他打了一个寒颤，突然退后了一步。
A retrodirective array can transmit a signal back to the interrogator ’ s position without any a priori knowledge of the incoming angle or relying on sophisticated digital signal processing algorithms . this merit makes it have good applied possibilities in modern military , especially digital commercial communication systems 方向回溯天线能够自动跟踪来波方向,而不需要来波方向的先验知识和复杂的数字信号处理算法,这一特点使其在现代军用、尤其民用数字移动通信系统中有很好的应用前景。
Based on an analysis on the present situation and development of three kinds of signal systems ( the point system based on interrogator responsor , the quasi - moving block system based on digital track circuit and the moving block system based on wireless data transmission ) in urban rail transit , some suggestions on the localization of signal system of urban rail transit are put forward 摘要在分析三种城市轨道交通信号系统制式（基于查询应答器的点式系统、基于数字轨道电路的?移动闭塞和基于无线数据传输的移动闭塞）的现状和发展基础上，对实现我国城市轨道交通信号系统国产化提出建议。
