When designing a fermenter, one primary consideration is the removal of heat. There is a practical limit to the square feet of cooling surface that can be achieved from a tank jacket and the amount of coils that can be placed inside the tank. The three sources of heat to be removed are from the cooling of media after batch sterilization, from the exothermic fermentation process

一般说来,低阶行列式的计算要比高阶行列式的 计算要简便,于是我们自然地考虑到用低阶的行列式 来表示高阶的行列式的问题。为此,先引入余子式和 代数余子式的概念。 定义在n阶行列式D=(a中,把元素在的 第i行、第列划去,剩下的元素按原来的相对位置形 成的n-1阶行列式叫做元素的余子式,记作M称 A=(-1)做元素a的代数余子式
