幅度调制是用调制信号去控制载波的振幅，使其随调制信号线性变化，而保持载波的频率不变。
Amplitude modulation is to control the amplitude of signal carrier and make it change linearly with modulation signals and maintain its frequency.

And the extent of difference amplitude caused by impedance decrease is more than equivalent impedance increase.
当脉动幅度与平均磁场强度之比为有限值时，在一般情况下，控制方程中的非线性项不能略去，因而不能用WKB解来描述有限振幅脉动幅度的径向变化。
When the amplitude of the fluctuation is finite with respect to the average magnetic field intensity, the nonlinear terms in the garvening equations can not be droped and the WKB aproxima-tion fails.
