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
