| 摘 要： | 在概率论中有大量的实际问题需要用二项分布来求解,但二项分布的计算有时相当麻烦,计算量相当大,往往同普阿松分布来逼近二项分布以简化计算.对于这种逼近的近似程度如何,怎样估计其误差以达到预定的准确度等问题作了一些探讨.

| Abstract: | In dealing with probability theory, a lot of practical problems need to be solved with binomial distribution. Sometimes, however, the calculation may be very complicated and the amount of calculation may be very large. So, Poisson distribution is often employed to approxi-mate the binomial distribution to simplify the calculation. This paper has just explored some of the most important related problems in using Poisson distrbution to approximate the binomial distribution. |
