The giants and their carts of nuggets traveling through the field looked like shadows, moving through the dancing plants without disturbing them or even noticing them.
The intensity of traveling wave field averaged in a time period demonstrates that the characteristics of doubly localized traveling wave can be well described by the averaged wave field.
最后对一个时间周期上行进波场进行平均后说明，场的平均值可以很好的表征双局部行进波特性。

Traveling-wave interaction and secondary magnetic field is generated electromagnetic force, which is a straight line to run the basic principles of electric motors.
