非径向对称带状载荷作用下有限长圆柱体的应力和位移解

公民思想是托克维尔政治思想的重要内容,它包括谁成为公民以及如何成为公民两个方面。在谁成为公民的问题上,托克维尔立足于法国的历史、思想与文化传统,强调法国现代公民的生成不但包括从市民到公民的生成机制,而且包括一个从农民到公民的生成过程；在如何成为公民的问题上,托克维尔强调现代公民的培养不仅需要国民教育,更为重要的是需要公共生活的锻炼。托克维尔的公民思想对于当代中国的公民建设既具有方法论层面的意义,又具有重要的现实启发意义。

Solutions for stress and displacement within finite long cylinder under non-radial symmetry strip loading

Based on the essential equations of elastic mechanics for infinitesimal element, the stress and displacement at arbitrary point of finite long cylinder under non-radial symmetry area load, tangential load and torsion load were solved. Two displacement functions were obtained with the separation of variables, finite Hankel transform and Fourier Bessel series. Unknown constants in expressions of stress and displacement were solved by substituting general solutions of stress and displacement into boundary conditions of cylinder. Axial distributions of stress and displacement for work rolls were analyzed by using the analytical equations of stress and displacement.
