摘要
关注三个都含有Stirling公式形式简短易用的双边不等式.对其中之一得出了新的下界(左边)不等式.又根据双边逼近的观点,验证了改进后的不等式在逼近精度上优于Robbins的双边不等式.
Here concerned are several simpler an improvement of the two others. It is found given by our improved inequality is better than two-sided inequalities for n!. One of those is that the degree of two-sided approximation that by Robbins's two-sided inequality.
