Chapter 2 is devoted to study of exact solutions of the nonlinear evolution equations. Using solutions of a Bernoulli equation instead of tanh in tanh-function method we find some more general solutions of the KdV-Burgers-Kuramoto equation , and by using the nonlinear telegraph equation we show that there are many different choices on its balancing number m and the power n of the nonlinear term in Bernoulli equation by which we can recover the previously known solutions and also can derive new square root type solitary wave solutions. Exact solitary wave solutions for a surface wave equation are obtained by means of the homogeneous balance method. We also present an approach for constructing the solitary wave solutions and non-solitary wave solutions of the nonlinear evolution equations by using the homogeneous balance method directly, which is also used to find the steady state solutions, solitary wave solutions and the non-solitary wave solutions of the 2+1 dimensional dispersive long wave equations. The soliton-like solutions of the BLMP equation and the 2+1 dimensional breaking soliton equation are found by use of the symbolic-computation-based Method.

The title and bill of material in engineering drawings are important data source for product data integrated management. In order to reuse the CAD data, the paper presents an effective method for extracting part information from existing engineering drawings. Through analyzing the format of title and bill of material, several shape-position characteristics of tables are summed up from the view of macro-layout and microstructure. A new method to automatically extracting drawing information based on cell-grid and feature-point is proposed along with its algorithm principle and implementation steps. A software package based on the method mentioned above is developed and used in practice.

1引言工程图是工程设计的主要成果和制造加工的主要依据，CAD软件的广泛应用使得传统上对于纸质图纸的管理模式转变为对大量电子文件的管理模式·由于文件系统在实际应用中不能适应复杂大规模的管理模式，已经出现了各种各样的图档管理系统[1]·工程图中包含的零件信息在表现形式上体现纸格式的标准化为批量提取数据提供了可能性·作为计算机处理的对象，图纸信息自动识别成为数据管理和系统集成的一项关键技术·当前CAD管理系统所处理的数据对象比较复杂，面临由不同企业使用不同的绘图软件生成的图纸，其中的标题栏和明细栏或者由软件自动生

The result of this Structural Equation Model shows money attitude and risk tolerance scale, using saving as an independent variable showed that there was no significant influence among them; using debt as the independent variable, the power/Prestige factor has significant influence. In other words, people who tend to see money as the solution to problems are more likely to borrow. In addition, Power/Prestige factor (people who tend to see money as the solution of problems), Retention/Time factor (people tend to perceive that they budget their money.) and high risk tolerance factor has significant influence on investing.

实证结果显示，金钱态度与风险容忍度对储蓄与否均无显著影响，金钱态度中的权力/名望对借贷者行为有影响：倾向将金钱视为解决所有问题的方法的人较易有借贷行为；此外，金钱态度中的权力/名望、保留/时间二项因素以及风险容忍度对投资行为有显著影响：越将金钱视为解决问题的方法以及金钱时间观念重的人，也就是意识到将来老年生活或是未来金钱来源者，以及对於风险容忍度高的人倾向从事投资。

In order to practically predict the effect of the tree belt windbreak in mine-area environment protection, the flow through porous tree belts was numerically made. The airflow-tree canopy action was considered into the momentum equation as the resistance term, and then the resistance between obstruction and airflow was expressed numerically.

为了更好地发挥防护林带在矿区生态环境保护中的效用，采用数值模拟的方法预测防护林带的绕林流场，其中将气流－树木相互作用视为阻力项添加到动量控制方程中，由障碍物表面对空气流动的阻力来描述林带的遮蔽效应。

In the current design framework concerning two-color microarray experiments, random errors are usually assumed to be uncorrelated random variables in the statistical models used to construct designs, but it is often more reasonable to acknowledge that there could be some correlation structure among the random errors. Particularly, when the technical replicates are used in the experiments.

在与微阵列实验设计相关的研究中，大部分被用来建构设计的模式其误差项均被假设为不相关的随机变数，然而这似乎与某些实际的情况相违背，例如当实验中若使用所谓的技术性重复时，不同晶片的实验结果间就可能会产生相关。
