Web基于MCKD-Teager能量算子的滚动轴承故障特征增强. 式(6)是针对连续时间信号的Teager能量算子的定义,而对于离散时间信号x(n),其Teager能量算子将变换为. 由式(10)可知对于离散时间信号而言,每个时刻的Teager能量算子的计算只需要3个采样点,因 … WebThe Python mock object library is unittest.mock. It provides an easy way to introduce mocks into your tests. Note: The standard library includes unittest.mock in Python 3.3 and later. If you’re using an older version of Python, you’ll need to install the official backport of the library. To do so, install mock from PyPI: $ pip install mock
