According to the plane cross section assumption, configuration of a rod is expressed as a history of the cross section with arc coordinate. A special solution which stands for equilibrium in straight line state is obtained from differential equilibrium equation. Linear perturbation equation is derived and its general solution is obtained in which the integral constants are determined by constrained conditions at two ends of the rod. The condition of existence of non zero solution of the integral constants gives to the Greenhill formula of exact elastic rod model, which shows that the boundary of stable area is a closed curve and of symmetry, and inference of shearable and extensible to stability of the rod is depend on three factors: difference between flexibility of shear and extension of a section of the rod, bending stiffness and the length of the rod.

基于平面截面假定，弹性杆的位形表达为截面的弧坐标历程，根据平衡微分方程得到了两端受力螺旋作用时的直线平衡特解，导出了线性化扰动方程及其通解，积分常数根据两端铰支时的边界条件确定，并根据其存在非零解的条件得到弹性直杆精确模型的Greenhill公式，表明稳定域为一对称的封闭区域，拉/压和剪切对稳定性的影响取决于：拉/压柔度与剪切柔度之差，抗弯刚度和杆长这三个因素

The IR analyses proved that the polymerization effects really occurred. The BET adsorption test indicated that the adsorption amount of MIPMs to LMD was as three times as that of non-imprinted microspheres. The controlled release test indicated that the release ratio of LMD on NIPMs was linearly increased with increasing time, which suggests that the release process is completely controlled by diffusion. Meanwhile, the release ratio of LMD on MIPMs was curvedly increased with increasing time, which indicates that the release process is controlled by both diffusion and the imprinting effect.

药物扩散实验表明， LMD在非印迹微球上的释药率几乎与时间呈直线关系，说明其释药过程完全受扩散控制；而LMD在MIPMs上的释药率则呈曲线上升趋势，说明其释药过程除了受扩散控制外，还受到药物模板分子与MIPMs之间的印迹效应的协同作用的控制，从而达到了缓释药物分子的目的。

The classical theorists resemble Euclidean geometers in a non-Euclidean world who, discovering that in experience straight lines apparently parallel often meet, rebuke the lines for not keeping straight--as the only remedy for the unfortunate collisions which are occurring.

古典学派的理论家们很像置身于非欧几何世界中的欧几里德几何学家们，一旦发现在日常经验中两条显然平行的直线经常会相交，他们就会指责说线没有保持平直——这被看作是解决两条线发生不幸冲撞的唯一办法。

This research conducts a two-factor between-subject factorial experimental design, namely 2 (line/snake queuing configuration)×2 (continuous/discontinuous television program). We also exploit the two-way Ancova method. Excluding the interference by mood state and waiting tolerance, we study how the above-mentioned two factors affects consumers' perception of waiting time.
