边界层

A boundary layer theory of shell buckling,which includes the effects of nonlinear prebuckling deformations, large .

将壳体屈界层理论推广到复合材料层合剪切圆柱板受侧作用情况。

In this article the nonparallel stability of the boundary layer is investigated effectively by using the parabolized stability equations (PSE).

采用极为有效抛物化稳定性方程(PSE)方法研究界层非平行稳定性。

Boundary layer theorem, isothermal and isoflux vertical plates, asymmetric isoflux vertical parallel plates of free convection, optimum and maximum channel space will be discussed.

界层理论，等温、等热流垂板，等热流非对称之垂两平行板自由对流以及最佳及最大气渠板距将被讨论。

Ordinarily, the thickness of velocity boundary layer and grid Reynolds number are used as the delimitating standards for flow field and aerothermal heating computations respectively.

通常做法是，对于流计算以速度界层厚度作为法向网格尺寸划分标准，对于热流计算则根据网格雷诺数确定网格尺寸。

The horizontal nonhomogeneity of the background wind and pressure fields influences the term of the inertial force in the motion equation and the wind speed at the upper boundary of the PBL.

背景水平非均匀影响了界层运动方程中惯性力项及界层上界速。

Such results are gotten: (1) Due to the unique topography the wind of Beijing area during the day time is southern anabatic wind and in the night is northern katabatic wind in summer.

(1)北京区域夏季界层受西北特殊地形影响,夜间低层大气流常表现为由北向南下坡,白天逐渐转为由南往北上坡。
