此线的东北与西南，地磁湾扰、磁暴急始等短周期事件垂直分量的变化△z呈现反号。

△ Z ( Changes in the Vertical field ) for the sudden storm commencements and geomagnetic bays to the northeast and southwest of this line appear opposite in signs .

由于中子和正电子的磁矩恰好和质子和电子的磁矩反号，故减弱了太阳内部的固有磁场，从而减弱了太阳的活动。

The inner magnetic fields of the sun is then weakened and solar activities are slowed down because magnetic moments of neutron and positron are opposite to that of proton and electron .

利用定性分析和数值试验的方法证实这类三时间层格式有时容易出现非线性计算不稳定，尤其是两步计算初值反号和耗散系数过小的时候是如此。

By means of qualitative analysis and numerical experiments , it is shown that nonlinear computational instability is prone to occur for three ( time ) level schemes , especially when two-step computational initial values have opposite signs and the dissipation coefficient is very small .

因为子Shell有许多用途，所以与组合或者反勾号操作符相比，您可能更喜欢使用它。

Because the subshell has so many uses , you might prefer to use it always instead of a combination or the back tick operators .

在Shell对命令行进行解释时，将执行反勾号之间的命令，并在最终的扩展结果中使用该命令的输出。

A command between back ticks runs as the shell interprets the command line , and the output of the command is used in the final expansion .

尽管通常运行子Shell将聚合的输出通过管道传递给单个命令，但您还可以使用子Shell对命令进行扩展，就像反勾号那样。

While it 's common to run a subshell to pipe aggregated output to a single command , you can also use a subshell to expand a command in place , just like back ticks .
