The results show that the ultimate stability bearing load by nonlinear analysis is close to the test load, they only have 10% deviation. For steel bridge towers, the correlation of the panels in the section of rectangle with chamfers is more obvious than that in the section of rectangle. If the four angles of the rectangle section were cut off, a panel with the smaller ratio of width to thickness forms, which can supply effective constraint to other weak panels with the larger ratio of width to thickness.

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。
