这种方法利用一光学系统和电路，把线值差转换为时间差来测量。
This method was changed from measuring the dimension difference to the time difference measurement by using an optical system and circuitry.
该方法通过对原始声源运动轨迹的分析，对声源信号进行多普勒调频，并根据耳间时间差对双耳信号进行调相。
The sound signal is Doppler FM modulated based on the analysis of the moving track of the original source, and then phase modulated according to the interaural time difference.
激光-超声方法是通过测量由流动引起的超声脉冲信号在两束或更多来激光之间传递的时间差实现旋涡场测量的。
Our laser - ultrasonic method is better than existing laser methods for measuring flows. So we use our laser - ultrasonic method to measure the vortex field of the flow.
