针对淹没在噪声中的弱信号测量，利用随机共振技术进行了信号检测的研究。

In order to detect weak signals overwhelmed in noise, the method of signal detection is investigated using the principle of stochastic resonance.

为了满足地震勘探高精度、高分辨力的需要，进一步研究了多普勒测量技术和弱信号检测技术。

To meet the seism detections require of high accuracy, high resolving power, the measurement technique of Laser Doppler and detection technique of faint signal are further researched.

同时测量周期越长，仪器对弱信号的识别能力越强，测量误差越小。

It is the longer to measure cycles, the stronger the capability of instrument recognition to the weak signal is, it is the less to measure the error.
