In this project, we study the theory of higher order differential equations in Banach spaces and related topics. We solve an open problem put forward by two American Mathematicians and two Italian Mathematicians concerning wave equations with generalized Weztzell boundary conditions, introduce an existence family of operators from a Banach space $Y$ to $X$ for the Cauchy problem for higher order differential equations in a Banach space $X$, establish a sufficient and necessary condition ensuring $ACP_n$ possesses an exponentially bounded existence family, as well as some basic results in a quite general setting about the existence and continuous dependence on initial data of the solutions of $ACP_n$ and $IACP_n$. We set up quite a few multiplicative and additive perturbation theorems for existence families governing a wide class of higher order differential equations, regularized cosine operator families, regularized semigroups, and solution operators of Volterra integral equations, obtain classical and strict solutions having optimal regularity for the inhomogeneous nonautonomous heat equations with generalized Wentzell boundary conditions, gain novel existence and uniqueness theorems,which extend essentially the existing results, for mild and classical solutions of nonlocal Cauchy problems for semilinear evolution equations, present a new theorem with regard to the boundary feedback stabilization of a hybrid system composed of a viscoelastic thin plate with one part of its edge clamped and the rest-free part attached to a visocelastic rigid body. Also we obtain many other research results.

By the FEA model that the recharge effect had been taken into account, the surface settlement and the surface differential settlement of the ground surface which was out of the recharge position could be greatly reduced, the recharge effect at far foundation pit wasmuch more apparent than at the near position. By the FEA model that the water-seal effect had been taken into account, the surface settlement and surface differential settlement of the ground surface could be largely reduced; the reduction of the total settlement and the differential settlement increased as the length of water-seal wall grew.

考虑回灌作用的有限元模型计算分析表明：设置回灌井或者回灌排水沟都可减小回灌处以外的地表总的沉降和不均匀沉降，随着排水沟离开基坑边距离的增加，回灌点以外的总沉降量和不均匀沉降都减少，回灌井埋设深度对周围地表沉降影响较小；通过考虑止水帷幕的有限元模型计算分析表明：设置止水帷幕可大大减小基坑周围土体总沉降和不均匀沉降，随着打设止水帷幕深度的增加，基坑周围地表总沉降和不均匀沉降都减小。

According to using easy company network safe expert introduces: According to the frangibility of Web application process that OWASP organization released 2007 the statistical result of 10 big ranks makes clear, the flaw of the script that cross a station, infuse, request that cross a station is forged, information divulges the problem that waits for a respect to remain the hacker's at present popular attack way, and be atttacked with SQL infuse especially among them and cross station script attack to attach most importance to, the lawful sex that infuse of so called SQL is atttacked even if uses programmer to do not have pair of user data-in when writing code undertakes judging, bring about the person that inbreak to be able to command through insert and carrying out baleful SQL, obtain data to read the attributive; that take and revises and attack of the script that cross a station is join baleful code through be in the webpage, when the person that visit browses a webpage, the administrator of means prevail on that baleful code can be carried out or ceases through giving an administrator post a letter is browsed, win administrator limits of authority thereby, control whole website.

据动易公司网络安全专家介绍：根据2007年 OWASP 组织发布的 Web 应用程序脆弱性10大排名的统计结果表明，跨站脚本、注入漏洞、跨站请求伪造、信息泄露等方面的问题仍然是现在黑客流行的攻击方式，而其中尤以SQL注入攻击和跨站脚本攻击为重，所谓的SQL注入攻击就是利用程序员在编写代码时没有对用户输入数据的合法性进行判定，导致入侵者可以通过插入并执行恶意SQL命令，获得数据读取和修改的权限；而跨站脚本攻击则是通过在网页中加入恶意代码，当访问者浏览网页时，恶意代码会被执行或者通过给治理员发信息的方式诱使治理员浏览，从而获得治理员权限，控制整个网站。
