  • 简介:构造工程的地里的聚合物修正有历史将近90年。尽管那些修正被分类进物理修正,到某程度的机械性质,水抵抗,化学抵抗和耐久性被不同聚合物修正改进了。获得似水泥的材料的更好的性能,化学修正被测试了。在这研究,环氧基树脂与它的相应hardener在修改系统作为一个占优势的修饰词被设计了。氨基的sulfonate,添加剂,被用来改进系统可使用性。当它有特殊的功能的组,功能的silane被用来在环氧基树脂,水泥一半和氨基的sulfonate之中建立连接。红外,拉曼光谱学,DSC和NMR执行的调查表明化学连接在修改系统在所有部件之中被建立了。当曲折力量和紧张实质地被改进了,曲折测试结果介绍化学修正的好效果。

  • 简介:一条交换系统途径被建议与通讯限制为联网的控制系统(NCS)建模。这使我们能把交换系统的富有的理论用于分析如此的NCS。足够的条件在NCS的稳定上被介绍。稳定状态/产量的反馈控制器能被使用一些线性矩阵不平等(LMI)的可行答案构造。我们的建议途径的优点是NCS的行为能被没有扩充系统,考虑交换了系统学习。一个模拟例子被得出说明建议途径的有效性。
