Thirdly , according to the conservation of energy principle , this paper analyzes the relationship between the hot ? ire and the airflow rate , establishes primary model of the hot ? ire . in this paper the simple mathematical model of pfras were given out （ 3 ）利用能量守衡的原理，分析了传感器敏感元件中的热线与气流速度之间的关系，建立了热线的基本模型，从而给出压电射流角速度传感器的数学模型。
In the eddy - current testing , testing coil is the sensitive component connecting the specimen and the instrument , so it is called transducer . the information of the test specimen is reflected by the variation of the coil impedance ( or induced voltage ) 在涡流检测中，检测线圈是用来连接测试仪器和被测试件的敏感元件，它是涡流检测中的传感器，被检试件的信息是通过线圈阻抗(或感应电压)的变化反映出来的。
Vision sensor system is an integration of optics , mechanics and electronics mainly based on ccd image sensor . this system is relational with mechanics , optics , electronics , computer vision , digital image processing and software engineering 视觉传感器系统是以ccd图像传感器为主要敏感元件构造而成的一个集现代光、机、电技术为一体的集成系统，涉及机械、光学、电子、计算机视觉、数字图像处理、软件工程等方面的技术。
Since the symbolic series are digital values themselves , it is very convenient to be acquired by logic judgment and processed by computer . in the part of weak signal detection , a new method of signal detection based on all parameters sensitivity of chaotic systems is proposed 在信号检测的应用方面，提出了利用混沌系统的整体参数敏感性进行信号检测的新思路，与传统的测量方法有很大的差别，测量过程中把所有的敏感元件都考虑在内。
With its minimized structure , the path provides an optimal light - amplifying ratio ; ( iii ) the position sensitive detector ( psd ) is just located in front of the visual sight of operator , this makes the observation and operation more easily 该系统设计有特殊的光路，结构简洁，体积小，通过多次反射提高反射臂的光程，保证了最佳的光杠杆放大比；同时，检测系统中的位置敏感元件( psd )光敏面位于正对视线的方向，易于afm系统的操作和观察。
In the early stage of experiment , an in - material thin film manganin gauge was studied . this in situ gauge was manufactured by single - step thin film processing , namely , manganin piezoresistance element was prepared on inorganic substrates such as ceramic , microcrystalline glass , etc by sputtering 在实验的初期，本文还研究了“在位式”的锰铜薄膜传感器，即首先在陶瓷或微晶玻璃基板上沉积锰铜敏感元件，然后用粘贴ptfe薄膜的方法完成传感器的封装。
