The study of spatial configuration and characteristics of pulsed-wire velocity probe shows that: the yaw-and pitch-response characteristics have a good behavior due to the asymmetrical arrangement of the prongs. Because the amplitude of sensor wire response signal changes with the flow velocity, the differentiated signal is selected to trigger a voltage comparator. The pulsing frequency is restricted to about 100Hz to allow the wire to cool between pulses. The first velocity probe with big acceptance cone has been developed in China, and the way of measuring the Reynolds normal and shear stress and application have been given in this dissertation.

对脉冲热线空间速度探针的空间结构及特性的分析表明：三根长支架平行且安置于同一平面的探针结构可以获得大的测量角和好的测量性能；由于传感丝的响应信号幅值随流速变化较大，故应采用微分法进行信号处理；对于5μm的传感丝由于散热时间基本不变，约为10ms，故脉冲发射的最高频率为100Hz；本文在国内首次研制成功了一种大测量窗的脉冲热线空间速度探针，并给出了测量雷诺应力的方法和实例。

Query signal is used to start motor. Interrupt signal is used to warm start motor.

设置了一个查询口作为步进电机的开关设置了一个中断口用来热复位电机。

This instrument generated the sine wave signal which frequency could change in three situations. The sine wave signal inputted to the buffer amplifier, then divided into two groups, a group connected with oscilloscope to survey the peak-to-peak value of fundamental wave, another group connected with wave trap to filter out the fundamental wave, then the oscilloscope was used to survey the various sub-harmonics amplitude of the output.

该仪器是通过设计可变三种频率的正弦波信号发生器产生的正弦波信号，其输出信号经过缓冲放大器，输入放大器后分为两路，一路接入示波器，测量基波幅值；另一路接入陷波器将基波滤去，再用示波器测量其输出各次谐波幅值。
