描述了 1997 年 8 月在连云港核电厂厂址复杂地形上为求取复杂地形烟羽轨迹和扩散参数而成功进行的 10 次 SF6 示踪实验。SF6从 100 m 高气象铁塔顶部释放;取样点采用居民区面源与可能的弧线布点相结合的方法;每次采取约 50 个样品;分析采用气相色谱-电子捕获检测(GC-ECD)方法;天气分类若按 P-G 方法,C,D类天气各 5 次,若按?T-U 方法分类 10 次全为 D 类天气;采用最小二乘法求解每次示踪实验的扩散参数;并对取样时间对扩散参数的影响作了实验测定。
Described in 10 August 1997 in Lianyungang nuclear power plant site complex terrain in order to obtain complex terrain smoke trails and diffusion parameters successfully carried out 10 SF6 tracer experiments. SF6 is released from the top of a 100 m high meteorological tower; sampling points are constructed using a combination of residential area sources and possible arc locations; about 50 samples are taken at a time; GC-ECD (GC-ECD) ; Weather classification according to the PG method, C, D weather each 5 times, if by TU method classified 10 times all D weather; Least squares method to solve each diffusion test of tracer experiments; and sampling time on The influence of diffusion parameters was experimentally determined.
