摘　　要：在秦山核电厂址 2 0 0 2年逐时气象数据、SF6 实测大气扩散参数以及 5类天气取样候选方案的基础上 ,应用动态烟团模型 ,估算了 PWR-2严重事故在近区 (半径 1、2、3、5 km)各计算点造成的 95 %累积概率水平个人有效剂量与逐时滑移相应值的均方误差之和 。The sum of square error of individual effective dose at 95% cumulative probability level among the 5 sets of candidates of weather sampling criteria and the 'hour-by-hour' sampling method caused by PWR-2 serious accident at all calculated points within nearby region with a radius 1,2,3 or 5 km are calculated based on hourly meteorological data in 2002 and diffusion parameters from SF 6 tracer tests for Qinshan NPP phase II. The results are analysed and compared using the least squares method.
