1.什麽是图解法? 线性规划的图解法就是用几何作图的 方法分析并求出其最优解的过程。 求解的思路是:先将约束条件加以图 解,求得满足约束条件的解的集合(即可 行域),然后结合目标函数的要求从可行 域中找出最优解

在建筑工程中,当地基浅层土质不良,无法满足建筑物对地基变形和强度方面的要求 时,可选深层较为坚实的土层或岩层作为持力层,用深基础来传递荷载。深基础主要有 基础(国内桩基础深度已达120m,直径超过5m;小的仅70~80mm)、沉井和地下连续墙 等几种基本类型。其中,桩基础以其有效、经济等优点使用最为广泛,常应用于工业与民 用建筑、桥梁、港口等工程中

地基处理是一项历史悠久的工程技术。早在二千多年前,我国就开始利用夯实法、软 土中夯入石头、压密土层等方法进行处理。解放后先后采用过砂垫层、砂井化学和电化法 处理软弱地基。现在又发展了振冲法、强夯法、真空预压加固、加筋法等

Chapter 3 Pressure-activated membrane processes M. J. LEWIS, Department of Food Science and Technology, The University of Reading, Reading RG6 6AP 3.1 INTRODUCTION Over the last 30 years, a number of membrane processes have evolved, which make use of a pressure driving force and a semi-permeable membrane in order to effect a separa- tion of components in a solution or colloidal dispersion. The separation is based mainly on molecular size, but to a lesser extent on shape and charge. The three main processes
