high-pressure gradient的意思|示意

The high head produced by the impeller means high adverse pressure gradient within blade passage and because of this the flow often separates from the blade surfaces even at the design point.

低比转速泵的高扬程决定了叶片流道内逆压梯度比较高，这种压力分布使得水流易于在叶片表面脱流分离，这一现象甚至在泵的设计点也难以避免。

The technology of monitoring well bottom while drilling has high precision, which can control borehole pressure more precise, but also the scope of the pressure gradient is well established.

井下随钻流量监测技术具有很高的监测精度，能够对井眼压力进行更加精细的控制，还能够对压力梯度范围很好的确定。

In high speed drawing process, the pressure gradient of coating in die determines the magnitude of centering force and the concentricity of coating layers.

高速拉丝过程中，模具中涂料的压力梯度决定了对中作用力和光纤涂层同心度的大小。

Experiments show that a low permeable reservoir has a starting pressure gradient, and therefore different seepage rule from that of middle and high permeable reservoirs.

实验表明，低渗透油藏具有启动压力梯度，因此其渗流规律与中、高渗透油藏不同。

The south warm-wet airflow caused by the strong pressure gradient force between typhoon and Subtropical High supplies the abundant water vapor for the heavy rainstorm area.

在台风和副热带高压外围之间强气压梯度力产生的偏南暖湿气流为暴雨区带来了丰沛的水汽。

Dual linear gradient elution can be performed with two specially made glass container and a high pressure constant flow pump.

用两个特制的玻璃容器及一台平流泵即可实现二元线性梯度洗提。
