The theoretic calculating method of the maximum and the minimum water level in the differential surge tank has been derived firstly . also the explicit method of calculating surges in the differential surge tank has been deduced firstly by use of thaler series expansion . the calculating method of section of the well and the effective impedance hole in the surge tank has been gived 根據(jù)差動(dòng)式調(diào)壓室的基本微分方程,首次推導(dǎo)出了差動(dòng)式調(diào)壓室涌浪幅值的理論計(jì)算公式;并同樣利用泰勒級(jí)數(shù)展開方法推導(dǎo)出了差動(dòng)式調(diào)壓室水位波動(dòng)的顯式計(jì)算式;導(dǎo)出了差動(dòng)式調(diào)壓室大井面積和有效阻抗孔面積的計(jì)算方法。
