As a part of the project, this paper is mainly focused on the application study of ultrasonic life detector after disaster.
作为项目的一部分，本论文的侧重点主要是对超声波在灾害现场生命搜救中的应用进行研究。
Firstly, the paper studied the basic transmit properties of ultrasonic, and then a mathematical model of ultrasonic life detector was founded.
本文首先从超声波的基本性质入手，对超声波的各项传播特性进行了全面深入的研究，构建了超声波生命探测数理模型。
If that happened to a detector, its useful life would be short.
如果这样的话，那这个检测装置的寿命就会很短。
Lightman is inspired by real-life lie detector, APS Charter Member and Fellow Paul Ekman, who has spent 50 years researching and characterizing facial expressions and body movements.
Lightman博士这个任务的创造灵感来自现实生活中的谎言侦查员，美国心理科学协会的特别会员Ekman，他花了50年的时间研究面部表情和身体动作语言。
Because decision-making detectors is used to judge the request, so the text describe the generation and the life cycle of the decision detector.
由于要使用决策检测器对请求进行判断，所以文中对决策检测器的生成以及生命周期也进行了说明。
Unless auto-detect, user also can control ON/OFF by hand. No one activities for a while, Radar Detector will automatic turn off power to reduce power bill amount and extended product life.
除自动侦测外，使用者亦可手动控制开关，当一段时间侦测无人员活动时，雷达灯控即会自动关闭电源，节费电费并延长产品使用寿命。
The principle of cable-type temperature detector is introduced. The fault mechanism of the device is analysed. A bodily example of life testing is given also.
介绍了电缆型温度探测器的工作原理，分析了损坏性的和漂移性的失效机理，并举例介绍了寿命试验。
So far, the team has only tested its lie detector on willing volunteers rather than in a real-life, high stakes situation.
到目前为止，研究团队只在乐意做的自愿者身上测试其测谎仪，而不是在现实生活、高风险的情况下进行。
