查询词典 shear stress

The induction periods and particulate fouling asymptotic resistances of arc line tube were obtained by comparative experiment under various particulate concentration and liquid velocity. The flow field and shear stress in the arc line tube were numerically simulated and analyzed.

文中通过不同流速和微粒浓度下微粒污垢的加速实验，得到了弧线管微粒污垢渐近热阻值和诱导期；同时，用数值方法模拟了弧线管的内部流场和壁面剪切力。

If the outward normal is negative, the shear stress is positive when in points in the negative direction of the coordinate axis which it parallels.

反之为负。例如：在X反方向的平面里，XY，XZ的值就为负。

If the outward normal is positive, the shear stress is positive when it points in the positive direction of the coordinate axis which it parallels.

如果该平面法向为正，如XY，XZ。则当剪应力方向与跟它平行的轴相同，则为正。

Shear stress boundary condition is used at the point of plastic deformation.

在均匀网格下这一方法的计算精度为0。

From the calculation result, we find that the shear stress is equal in center field.

将Fluent计算的结果与理论公式的求解结果进行比较，发现二者在中间

Methods: Parallel-plate-flow-chamber was used to assay the influence of shear stress on endothelial cells morphology and cytoskeleton and apoptosis and NO secretion. endothelial cells morphology was observed under microscopy, cytoskeleton was showed by Coomassie brilliant blue staining, fluorescence stain, and transmission electron microscopy, apoptosis was detected by FCM, NO of circulating culture medium was assayed by NO kit.

细胞形态显微镜下直接观察；细胞骨架通过考马斯亮蓝染色、荧光标记和透射电镜进行观察；细胞凋亡通过流式细胞仪检测进行分析，一氧化氮通过流动循环培养基的收集后应用检测试剂盒进行检测分析。
