摘要
根据描述非线性渗流二次函数和幂函数两种表达式可以描述同一渗流场的特点,提出两者之间应有同一性,即它们之间可以相互转换.并通过最小二乘法的数学手段,导出了两种函数相互转换的关系式.对层流和充分紊流两种特殊渗流以及假定值的检验表明。
According to the two kinds of expressions of quadratic function and power function for describing the non linear seepage flow,this paper advances that the two kinds of expressions should have identity, that is they can transform each other,and exports the relational expression of the two kinds of functions transforming each other using method of least squares. From the verification of the two kinds of particular seepage flow and the hypothesis data,the relational expression can express the identity between them adequately.
