所以天气预报并不擅长捕捉即将到来的气流阻滞事件或静止的高压脊。
So weather forecasts are not very good at capturing the imminent arrival of a blocking event or a stationary ridge.
它将会在这种气流上升如果想要，它能在空气中保持绝对静止很长的时间，即使在风中。
It will ascend in such currents if desired. It can remain absolutely stationary in the air, even in a wind, for great length of time.
在实际操作过程中，选择合理的床层静止高度和气流脉动频率对提高传热系数有利。
In practice, choosing the static height of the bed layer and the frequency of the gas pulsation properly can increase the heat transfer coefficient.
