Description: 加强肋
理想的设计
为了克服壁厚大可能引起的问题，使用是一种可减少壁厚并能增加刚性的有效方法。
一般来说，部件的刚性可用以下方法增强
增加壁厚；
增大弹性模量（如加大增强纤维的含量）；
设计中考虑。
如果设计用的材料不能满足所需刚性，则应选择具有更大弹性模量的材料。简单的方法是增加塑料中增强纤维的含量。但是，在特定壁厚下，这种方法仅能使刚性呈线性增长。更有效的方法是使用经过优化设计的。由于惯性力矩增大，部件的刚性便会增大。在优化的尺寸时，不但要考虑工程设计应当考虑的问题，还应考虑与生产和外观有关的技术问题。
优化的尺寸
大的惯性力矩可很容易地通过设置又厚又高的来实现。但是对热塑性工程塑料，这种方法常会产生制品表面凹痕、内部空洞和翘曲等问题。而且，如果的高度过高，在负荷下结构将有可能膨胀。出于这种考虑，必须在合理比例内保持的尺寸（见图1）。-stiffened ideal for the design of large thickness overcome the problems that may arise. use of a reduced wall thickness and rigidity can increase the effective method. In general, the rigid parts of the following methods can be used to enhance increased thickness; increased elastic modulus (such as increasing fiber content); Design considerations. If the design of the materials used can not meet the rigid requirements, they should have a greater choice of elastic modulus of the material. The simple way out is to increase plastics reinforced fiber content. However, in specific thickness, such methods can only make rigid linear growth. More effective method is to use the optimized design. As the moment of inertia increases, the rigid parts will be increased. The optimum size, not only to con

Description: 光孤子传输特性模拟 在光纤通信中，光脉冲信号在光纤中传输的过程中会受到色散、损耗和非线性等作用的影响而不断地发生演化和畸变。脉冲演化的规律遵循非线性薛定谔方程（NLSE）。由于NSLE 在一般情况下无法求得它的解析解，因此通常需采要用数值方法来求解，最终归结于求解归一化的NLSE。本文使用了分步傅里叶方法对归一化NLSE 进行了求解，并模拟了输入为一到三阶双曲正割光脉冲条件下光脉冲传输演变情况。-soliton In optical fiber communications, the optical pulse signals in fiber-optic transmission process will be subject to dispersion, loss and non-linear effects, such as constant evolution and distortion occurs. Pulse to follow the evolution of the law of nonlinear Schrö dinger equation (NLSE). Because NSLE under normal circumstances can not achieve its analytical solution, it normally takes mining use numerical methods to solve, and ultimately attributed to solving normalized NLSE. This article uses the step-by-step Fourier method and normalized NLSE was solved, and analog input for the first-order,second-order and third-order hyperbolic secant optical pulses under the conditions of the evolution of optical pulse transmission.
