external boundary meaning in English
外边界
Examples
- There are two crucial boundaries in administrative power : internal boundary and external boundary
行政权力有两条重要边界：内边界和外边界。 - According to actual situation of production wells , external boundary conditions and coupled inner boundary conditions between welibore and adjacent rocks , welibore and production zones , adjacent rocks and production zones are constructed , and an alternate direction implicit finite difference algorithm ( adi ) is used to solve temperature models
根据生产井的实际情况，构建起外边界条件以及井筒与围岩、井筒与产层、围岩与产层之间的耦合内边界条件，采用交替方向半隐式有限差分方法( adi方法)求解所建立的井下温度场模型。 - Due to the existence of the eddy and the abrupt bend of the stream line , the pressure on the four faces has the distribution as follow : the lowest pressure appears at several centimeters after the angle point along the top boundary , the highest pressure appears near the center line of the vertical shaft on the bottom boundary , near the angle point , the pressure on the inner boundary decreases with the decreasing height , the pressure on the external boundary decreases slightly in the right - angle region , and increases obviously near the corner
回流漩涡的存在，以及直弯处流线的急剧弯曲，导致壁面压力分布在上表面距弯点一定距离后出现压力最小值，下表面上，在竖井中心线略偏下游的位置出现压力最大值，竖井内表面接近弯点处出现压力沿程降低的现象，竖井外表面压力在进入直弯后先是沿程略有降低，在直弯角落处又明显升高。
