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

将壳体屈曲的边理论推合材料合剪切圆柱曲板受侧压作用的情况。

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

采用极为有效的抛物化稳定性方程(PSE)方法研究边的非平行稳定性。

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

边理论，等、等热流垂直板，等热流非对称之垂直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.

通常的做法是，对于流场计算以速度边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.

背景风压场的水平非均匀影响了边运动方程中的惯性力项及边的上风速。

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)北京区域夏季边风场受西北特殊地形的影响,夜间低大气流场常表现为由北向南的下坡风,白天逐渐转为由南往北的上坡风。
