Low-Noise Increasing & Decreasing

Low resolution and low signal noise ratio are big obstacles in the way of increasing the accuracy and level of deep strata exploration.

深层地震反射资料分辨率、信噪比低是制约进一步提高深层勘探精度，加大深层勘探力度的重要因素。

Wavelet breadths of edges and noise display different identities with increasing of the scale, so edges and noise can be respectively detected from the signals of low signal-noise ratio.

随尺度增加，边缘和噪声的小波幅值表现出不同变化特性，从而在低信噪比的信号中检测出噪声和边缘。

With the increasing use of optical coherence tomography, the study of the signal-to-noise ratio in low-coherence interferometry has been of increasing concern.

光纤低相干干涉技术已经被广泛用于高灵敏度的测量技术当中。
