| 摘要: |
| 以施桥船闸2001年到船资料为样本，运用数理统计方法，进行了日到船量服从泊松分布和正态分布的假设检验，将船闸日到船实际值与理论值比较后表明，船闸日到船吨位和到船数的概率分布均接近正态分布。 |

| Abstract: |
| Based on the data of ship arrival at Shiqiao Lock in 2001 and by use of mathematic analysis methods, the daily ship arrival is assumed to accord with the Poisson distribution and normal distribution. Comparison between the observed ship arrival and theoretical ship arrival shows that the distributions of daily-arriving-ship quantity and daily-arriving-ship tonnage are close to the normal distribution. |
