论MVC模式改进Model 2x模型王鑫,孙小平摘 要:研究了MVC(模块,视图,控制)模式的改进结构,该模式可以使业务逻辑与现实逻辑相分离,增强可维护性.以Java语言为基础探讨了使用Struts和XSLT相结合实现MVC,架构出具有良好的扩展性和伸缩性的基于Web的系统.介绍了Model1模型和Model2模型以及每个模型的优缺点,由此论述MVC模式所衍生出来的Model2x模型.实际应用表明该方法有助于提高代码的可重用性和灵活性,通过将问题划分为更小的组件,当技术空间或问题空间中出现变化时会有更多的机会重用代码,在实际项目应用中效果良好.关键词:MVC模式;Model 2x模型;Java和xml开发语言;Web系统;......
, defects are distributed randomly over the whole material. For this reason, it is too difficult to derive an exact hysteresis model composed of several physically meaningful material coefficients. To date...>. Although this approach can eliminate the problem, it has high cost and also needs an appropriate mathematical model for better performance. Therefore, in this work a phenomenological model consisting......
