Short wave is good for broadcasting very long distances. The short wave signals bounce off the ionosphere that surrounds the Earth, back to the ground and then back to the ionosphere.
短波有利于长距离传输广播节目，短波信号被围绕地球的电离层反射，能在大地和电离层间来回反射。
Comparing with the flux of turbulent exchange of latent heat and the flux of upward long-wave radiation the flux of sensible heat exchange is very small.
与潜热的湍流输送及海表面向上的长波辐射通量相比，感热的湍流输送量很小。
Vector acoustic field is a very important part of sound wave, but the vector information of acoustic wave has been unwitnessed for a long time.
矢量声场时声波场的重要组成部分，但在相当长的一段时间内没有受到重视，声波的矢量信息却被忽略了。
Traders who are short should be careful here as a long turning point may follow very quickly if wave c is already completed.
短期的空方需要者应小心了，因为这里作为一项长期的转折点可能会很快出现反转，假如波c浪已经完成了的话。
