采用低能耗的终端过滤方式进行陶瓷膜法海水淡化预处理,比较了“絮凝沉降+陶瓷 膜”和“砂滤±陶瓷膜”两种预处理工艺.前者延长了膜再生周期,其陶瓷膜的平均渗透通量是 后者的1.6倍达到220L/(m2+),产水回收率大于90%经陶瓷膜预处理后的产水水质稳 定达到反渗透膜的进水水质要求结果表明,“絮凝沉降+陶瓷膜”预处理工艺明显优于“砂 滤+陶瓷膜”预处理工艺

向量组A:a1,a2,am线性相关的充要条件是矩阵A=(a12,…,am) 的秩小于向量的个数m;

定理:设λ1,2…m是方阵A的特征值,P1,P2,…Pm依次是与之对应的特征向量,如果1,2,…各不相同,则P1,P2,…P线性无关.(P.120定理2)

一、矩阵的秩的概念 定义:在mn矩阵A中,任取k行k列(k≤m,k≤n), 位于这些行列交叉处的k2个元素,不改变它们在A中所处 的位置次序而得的k阶行列式,称为矩阵A的k阶子式 显然,mxn矩阵A的k阶子式共有C个
