In this paper, the differential operator of thermospheric tides for which the effects of the average wind and wind shear are taken into account has been derived. From the inversion of the finite Hankel transform, the integro-differential equation for the thermospheric temperature is obtained, and this integro-differential equation can be solved by the method of the Green's function.

本文试图用统计方法,将金属脆性断裂的微观过程与宏观过程结合起来,把断裂理论建立于微裂纹发展动力学的统计基础上。 脆性断裂实质上是在小的范性变形过程中微裂纹成核长大的非平衡统计过程和单个主裂纹的传播过程。 本文导出了描述这种非平衡统计过程的微分积分方程,并从位错机理出发研究了微裂纹动力学,从而解出了微裂纹的分布函数,求出了金属试样的断裂几率,进而导出了延伸率、断裂强度、范性功、裂纹扩展力、断裂韧性、临界裂纹长度、范性-脆性转变温度以及它们的统计偏差与其它有关物理量之间的函数关系。

In this paper newly-developed universal method for solving the indirect problem and the hybrid problem of turbomachine cascades on an arbitrary stream sheet of revolution is presented. To this end, a non-orthogonal curvilinear (streamline) coordinate system (-stream function) is employed and regarded furthermore as a mapping onto a map plane , where the indirect and hybrid-problems are transformed into conventional boundary value problems with a known and very simple (rectangular) domain boundary.

本文对任意旋成面叶栅的气动反命题及杂交型命题提出一个通用的新解法。为此,引入一组斜交流线座标系,并将它看作一个映射,然后在映象平面上求解。提出了四种求解方案:偏微分方程组法,偏微分方程法、微分-积分方程法和积分方程组法。 值得注意的是:①在本文对反命题的提法下,叶型封闭性可自动得到保证;②在映象平面上,质量守恒定律具有新的几何意义——映射的区域保持性:③这种流线座标系也可用于求解叶栅正命题及其它具有未定(自由)边界的问题。
