In this paper the equations of the stability and shear, flexural vibration of the straight bars with varying cross-section and the equations of motion of one degree of freedom systems with varying parameters are written as a unified self-adjoint differential equation of the second order eq.

(1) gives Bessel's differential equation.The stability and free vibration of multistory and tall buildings and high-rise and tower-type structures and some other problems may be solved according to the unified formula presented by the author. An example of calculating free vibration of Kwang-chow Hotel Building (27 storied) is given in the last part of this paper.

In the present paper, on the basis of Reissner type modified assumption, a refined theory which considers the transverse shear effect on the transversely isotropic circular cylinders is established and a tenth order governing differential equation ia derived. This equation can be resolved into two parts, one second order partial differential equation and a pair of complex conjugate fourth order partial differential equations. In view of mechanics, the first part represents the effect of transverse shear and the second part represents the result of classical thin shell theory. If we let the transverse shear stiffness approach to infinity, the governing equation of refined theory can be reduced to the classical thin shell equation. Dropping some small terms, the Morley, Novozhilov and Donnell eguations can be derived from the two complex conjugate fourth order equations.

本文在Reissner型修正理论的基础上,建立了一个横观各向同性圆柱形壳体考虑横向剪切变形的精化理论,导出了十阶基本微分方程式.该微分方程可以分解成一个二阶和两个四阶的共轭微分方程式;在力学上,前者代表剪切变形的修正项,后者对应于经典薄壳理论的结果.当壳体的横向剪切刚度很大时,证明了本文提出的精化理论同经典理论的一致性.略去一些次要项,两个四阶共轭微分方程可以退化为各向同性圆柱形薄壳的Mororley、Norozhilov和Donnell方程.

利用 Krall 公式,讨论了任—2n 阶微分型 L(y)乘以乘子 f(x)后,f(x)L(y)是否构成自共轭微分型的问题,并给出了乘子 f(x)的求法。
