stderr -- 标准误差.
Eff.Diam = 25.0m 有效直径 25 米.(有这么大的吗,mm吧?你漏了一个m?)
Eff.Area = 490.6 mm2 有效面积 490.6 平方毫米
Knownconc = 0% 已知浓度.Rest =0% -- 其余
Viewed Mass = 18000.00 mg -- 视重(质量)18000.00 毫克 == 18克
Sample height = 5.00mm -- 样品高度 5 毫米
< means that the concentration is < 0 mg /kg -- < 意思是浓度小于 每千克 里含0 毫克.
wt -- weight
part -- 部分
sum -- 总和
