说明: :在深海采矿环境中超声波传输介质里存在着大量气泡、扰动沉积物、机械噪声等背景噪声与混响,导致有用信号与高
噪声信号迭加在一起,严重影响了测距精度。采用小波分析方法将超声回波信号进行3层小波分解,适当设置门限阈值对小波
系数进行处理,然后对信号进行重构,有效地抑制了信号中噪声对测量精度的影响。研究结果表明:小波方法有很好的降低回
波信号中噪声的效果,其测距精度高于自适应滤波去噪后的测距精度。(There are much background and mixture noise in the course of ultrasonic wave transmission under deep
sea mining environment,such as air bubbles and disturbed sediment and mechanical noise.Because of these factors,
the useful signals and the high noise signals are combined together,which seriously affects the distance measurement
precision.Ultrasonic echo signals are decomposed into three layer wavelets,and a threshold is set to process the
wavelet coeficients.Then the signals are reconstructed.Accordingly the influence of environment noise on distance
measurement precision is effectively restrained.Research resuhs indicate that wavelet transform method is very useful
for noise reduction in signals.Its precision is higher than that of the adaptive filtering method.)

越厚越好.
(the multi-asperity sphere-shape model for surface contact between sulphurized layer and unsulphurized
layer is established.in which the height of sphere-shape asperities follows the Gaussian distribution.1he
frictional coeficients of sulphurized layers are analyzed by using plastic flown line theory.1he results show that
the frictional coeficient increases with the load.the frictional coeficient of ground surface is higher than that
of tumed surface in case of the same roughness.1he thicker the sulphuri[ed layer is.the higher the frictional
coeficient is.From the viewpoint of reducing frictional coeficient,the thickness of sulphurized layer should
be smaller.)

对模糊图像进行复原(代码中样例)后,进行ISNR值的计算。由于复原后图像和原图像可能存在对齐问题,而该对齐问题不影响复原结果的主观效果,因此该代码首次考虑这一问题并给出相应的图像对齐及ISNR计算方法。(Restoration of blurred images (sample code), the calculation ISNR values. Due to possible alignment problems and the restored image after the original image, and the alignment problem does not affect the results of the subjective effects of recovery, so the code for the first time to consider this issue and the corresponding image alignment and ISNR calculation.)
