主要研究同余方程∏_(i=1)~r(x+mi)≡∏_(i=r+1)~(2r)(x+mi)(mod p~μ)有解时, 关于m=(m_1,m_2,...,m_(2r))解数的问题.通过引入p-adic指数赋值,并比较该同余方程关于未知元x各项系数的p-adic指数赋值方法,得到r=6时,该同余方程关于m解数的上界估计.
主要研究同餘方程∏_(i=1)~r(x+mi)≡∏_(i=r+1)~(2r)(x+mi)(mod p~μ)有解時, 關于m=(m_1,m_2,...,m_(2r))解數的問題.通過引入p-adic指數賦值,併比較該同餘方程關于未知元x各項繫數的p-adic指數賦值方法,得到r=6時,該同餘方程關于m解數的上界估計.

The problem of the solution number about m=(m_1,m_2,...,m~(2r)) was studied, when the congruence can be solved. By introducing the conception of the p-adic exponential evaluation and comparing the p-adic exponential evaluations of each coefficient of x in the congruence, we obtain the solution number of m in the congruence when r=6.
