摘要
本文中以临汾地区降水氚值恢复为例,提出了大气降水氚含量历年值恢复的多元统计学方法,方法中考虑了取样点地理径纬度、取样点高程、降水量及离海洋远近等因素,利用IAEA/WMO监测网提供的资料,共建立了104个方程。临汾地区插值与渥太华站氚含量曲线作相似比较,选取上、下限两组值(1965-1978),1953-1964年各年值则通过与渥太华站相关求得。
A multiple linear regression statistical method for reconstructing the yearly average tritium content in precipitation is proposed, with Linfen area as an example.One hundred and four equations have been established by using the tritium contents provided by IAEA/WMO isotope-in-precipitation
network, in consideration at the same time of geographic latitudes and longitudes. the sampling altitudes .distance from sea or ocean, and the annual rainfall. The calculated values from all equations in Linfen area are compared with the tritium content measured in Ottawa, and the values of upper and lower limits during the period from 1965 to 1978 are selected. The values for individual year from 1953 to 1964 are obtained through correlation of tritiym contents in Linfen area and those measured in Ottawa.
