In this paper, the equations of motion of vortices in baroclinic atmosphere are derived in the light of classical hydrodynamics. Six factors determining the motion of vortices are discussed. Physical interpretation and some comments are given to the well-known steering principle. Application of these equations in the forecasting of the motion of typhoons are illustrated by three examples, and the results are better or as well as those of the synoptic forecasts. Possibility and limitation of their application...

In this paper, the equations of motion of vortices in baroclinic atmosphere are derived in the light of classical hydrodynamics. Six factors determining the motion of vortices are discussed. Physical interpretation and some comments are given to the well-known steering principle. Application of these equations in the forecasting of the motion of typhoons are illustrated by three examples, and the results are better or as well as those of the synoptic forecasts. Possibility and limitation of their application to the motion of middle-latitude vortices are also discussed.In the appendix, there are critical discussions of the role of the internal forces and the calculation of the amplitude and period of the meandering motion of typhoons in straight steering current.

本文根据流体力学的基本理论,得出了斜压大气中的涡旋运动方程。并讨论了决定涡旋运动的六个基本因子。对日常应用的高空引导观念给予比较明确的物理解释并加以修正。文中对这方程在预报台风移动的应用作了初步说明,也附带简单地谈到了中纬度系统的移动。在附录中还指出了关于系统内力作用的误解,并简单地讨论了台风运动的摆动周期和振幅。

This paper gives a derivation of the slope deflection equations for the determination of the secondary internal forces due to prestressing, shrinkage and creep for hyperstatic prestressed concrete structures of variable cross section. Tables of seconx dary fixed end moments for prismatic and haunched beams with straight and parabolic tendons have been prepared for use in practical applications, A method of using concordant pressure line for the elimination of secondary forces due to prestressing...

This paper gives a derivation of the slope deflection equations for the determination of the secondary internal forces due to prestressing, shrinkage and creep for hyperstatic prestressed concrete structures of variable cross section. Tables of seconx dary fixed end moments for prismatic and haunched beams with straight and parabolic tendons have been prepared for use in practical applications, A method of using concordant pressure line for the elimination of secondary forces due to prestressing is introduced. Other constr- uctional methods of avoiding secondary forces due to shrinkage and creep are reviewed. The problem of using the ultimate lood method to the theoretical analysis of hyper- static prestressed concrete structures is also discussed.

In this paper are presented integral expressions precise enough for computing the internal forces and vertical displacements of double curvature shallow shells under the action of a concentrated load over a certain distance from the boundary according to the moment theory of shells. In case of shallow shells of equal curvatures, these expressions can be easily integrated into formulae which are exactly the same as those given by E. Reissner, but for shallow shells of unequal curvatures, the solution is...

In this paper are presented integral expressions precise enough for computing the internal forces and vertical displacements of double curvature shallow shells under the action of a concentrated load over a certain distance from the boundary according to the moment theory of shells. In case of shallow shells of equal curvatures, these expressions can be easily integrated into formulae which are exactly the same as those given by E. Reissner, but for shallow shells of unequal curvatures, the solution is given in the form of series composed of Thomson functions, the convergence of which is considered to be quite good in the ordinary scope of application (1 < k1/k2≤2). Furthermore, formulae for the internal forces and vertical displacements of shallow shells of equal curvatures under the action of circular line loads and circular ring loads as well as their exact values at the point of a concentrated load for shallow shells of unequal curvatures are also given in the paper.

本文按有矩理论对作用在双曲扁壳并距离边界超过一定距离的集中載荷所引起的內力和位移值提出了具有足够精确度的积分表达式。在等曲率双曲扁壳的情况下,这些积分表达式可以很簡便地积出与E.Reissner相同的計算公式;对不等曲率双曲扁壳,本文則根据积分表达式給出了由Thomson函数組成的級数解,其收斂情况在常用的范围內(1
