噪声发生的英文
noise generation
例句与用法
- The result displays that there is always a dynamic friction component in the presence of squeal
结果发现，在摩擦噪声发生的区域，摩擦力总是有动态成分。 - Experimental results show that the filter gives superior performance compared with conventional filters and other fuzzy filter , especially , the superiority will more obvious when noise probability exceeds 0 . 3
实验结果表明，该滤波器滤波效果优于传统的滤波器和其它模糊滤波器，特别是当噪声发生概率超过0 . 3时，其滤波效果更加明显。 - This phenomenon shows that stick - slip motion and negative friction - velocity slope are not responsible for the present squeal . it is because these two generation mechanisms of squeal only govern the tangential vibrations
这个现象否定摩擦噪声发生的两个机理：粘着-滑动机理和摩擦力-相对滑动速度负斜率机理，因为这两个机理描述的是切向发生的摩擦振动。 - In the paper , through measurements of interior noise of existing railway vehicles in china , studies propagation routes and distributing characteristics , puts forward to the distributing rules of interior noise in different statuses and speeds , gets the main frequency band , it benefits to noise abatement and reduction design of existing and high - speed railway vehicles
