2) binomial thue equation
二项Thue方程
1.
In this paper,using some properties of Pell equations and binomial Thue equations,we prove that the equation x+…xm=yn has only the positive integer solutions (m,n,x,y)=(1,r,sr,s),(r,1,s,s+…+sr and (sr,r,1,s),where r and s are arbitrary positive integers.
利用Pell方程和二项Thue方程的性质证明了:方程x+…+xm=yn仅有正整数解(m,n,x,y)=(1,r,sr,s),(r,1,s,s+…+sr)和(sr,r,1,s),其中r和s是任意正整数。

对二项式产能方程的适用条件进行阐述,通过实例从机理上分析了频繁调节针型阀和仅将产气量或压力值进行简单的平均对产能评价所造成的影响。
3.
A method of binomial deliverability equation can be used in abandonment pressure evaluation to reveal the original pressure, burial depth, heterogenity, and to show the effects of different abandoning conditions on abandonment pressure.
二项式产能方程法评价气藏废弃压力能够反映出气藏原始压力、气藏埋深、储层非均质特征、以及不同废弃条件等多种因素对于废弃压力的影响,因此该方法评价结果较传统废弃压力评价方法如经验法、气藏埋深法等更可靠。
6) duality thrice multinomial

补充资料:二项方程
形如axn+b=0的方程,其中n为正整数,a、b≠0。将原方程化为xn=-ba的形式后,用复数开n次方的方法即可求解。它是用代数方法解一元n次方程的基础。
