upper bed

At upper flow regime, the total stream power gradually deviate the effective stream power from movable plane bed to existence of sand wave.

在高能态区，从动平整床面到沙浪的出现，总水流功率又逐渐背离有效水流功率。

When a thin interbed is thicker than 0. 2m, the upper and down interfaces generate two groups of reflection waves, by which both the bed thickness and reservoir characteristic may be known.

当薄层厚度大于0.2m时，在上、下层界面处会出现两组反射液，利用反射波信息可分辨出薄层厚度，评价其储集特性；

On the upper part of the bed there are special ways upon which the carriage and the tailstock slide.

在床身的上部有支架和尾架滑板的特别结构。

Upper incipient lethal temperature of short term thermal shock of two species of copepods ( 2) Initial temperature of catalyst bed is wholly too high.
