本文的中心目的有二:第一找曲面是代数曲面的必要兼充分条件,第二建立整式的各次因式种类的决定法以及整式可分解的条件.在§1作者建立了直线和曲面的交点重复度交比积及交比积函数的概念.在§2找出了代数曲面的交比积公式,此式,在§3定理三的证明中将要引用,实际上§2可看成定理三的引理.§3是本文的中心之一,在这一节中作者证明了两个定理:前一个定理指出代数曲面和任一定向多边形的交比积恒等于1;后一个定理指出和任一定向多边形的交比积恒等于1的曲面必是代数曲面.§4是本文中心之二,在这一节中作者建立了整式的因式判別式概念,一方面说明这些判別式经过四则运算有限多次可以求得,另一方面证明了 l 次因式判别式恒等于零是 l 次因式存在的必要兼充分条件.于是在理论上解决了各次因式存在与不存在以及整式是否质整式的判定方法问题,无须进行因式分解。此节是上节定理的应用.在§5作者算出二次整式的判别式,获得了二次整式可分解的必要兼充分条件,并且说明了所得条件等价于代数学中已知的结果。

In this paper is presented a simplified two-variable approximate theory, based on the C. Libovc and S. B. Batdorf's theory[6] for elastic orthotropic plates with transverse shear deformations. Assuming that there exists a potential function (x, y) for the traps-verse shear angles rx and ry (see eq. (2.9)), the total potential energy If (eq. (2.8)) can be expressed in terms of two independent unknown functions, the plate deflection w(x, y) and the potential (x, y). By the use of the principle of minimum potential energy the Eulcr dcffercntial equations (1.11) for w and and the boundary conditions (1.12)-(1.15) are obtained in Appendix I. The comparision between the results for critical compressive load for a particular case of square simply-supported plate based on the present theory and Robinson's results[8] based on [6] shows that the discrepancy is small, if the anisotropy is not too significant (Table I). It is shown in Appendix H. that for polygonal simply-supported isotropic plates for both the bending and the stability problems the present theory always gives the same results as the theory in [6]. Two kinds of free edges arc distinguished: "entirely free edges" with the boundary conditions as (3.14) and the "stiffened free edges" with the boundary conditions as (3.17). Analysis of examples for orthotropic plates with free edges shows that, in general, cannot be interpreted as the shear deflection.

本文根据C.Libove与S.B.Batdorf关于考虑剪切变形的正交各向异性弹性平板理论建立了一种简化的二变量近似理論。假设横向剪切角r_x与r_y具有势函数φ(见式(2.9),总位能Π(式(2.8))可以通过两个独立函数即板的挠度w(x,y)与势函数φ(x,y)表出。在附录1中利用最小位能原理推出了w与φ的Euler微分方程(1.11)与边界条件(1.12)-(1.15)。計算了四边簡支的方板的一个特例的临界受压載荷,计算結果与Robinson根据文献[6]所作的結果的比較,表明其间的差异很小,如果各向异性的程度不过于显著的話。在附录Ⅱ中证明了,对于直线多边形各向同性簡支板来讲,无論是弯曲或稳定問題,本文結果恆与根据文献[6]的理諭得到的結果一致。区別了两种不同的自由边:“完全自由边”,其边界条件的形式如式(3.14);“加强自由边”,其边界条件形式如式(3.17)。对具有自由边的正交异性板的分析表明,一般說来,φ不能解释为剪切挠度。
