平均磁场

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 .

全群的平均磁场强度约为2000高斯，在几个主黑子中测量到最大磁场为3300高斯。

The average magnetic field intensity of the total group was about 2000 gauss and the maximum magnetic field intensity measured in some main spots was 3300 gauss .
