这样，安装在红外光焦点运动轨迹上的热释电敏感元件被红外光焦点不断扫描而产生自主采样的热释电信号。
So, the pyroelectric sensor that is located on the moving track of the infrared focus is scanned by the infrared focus signal continuously and generates the autonomous sampling pyroelectric signal.
深入研究了近钻头空间姿态测量系统的结构、原理及安装等问题。对比分析了两种坐标系下测量和计算井眼轨迹参数的优缺点。
An intensively research on the structure, installation and working mechanism of the bit attitudes surveying system is given in this paper.
