| 摘 要： | 将水系沉积物样本数据转换到具有岩石样样本数据特征的水平上,近似地称为水系沉积物样品的"反推".文章利用"标准正态转换法"对此作了一些探讨:将两者的样本数据都转换成标准正态分布的形态,在此基础上,再将水系沉积物样本数据转换到岩石样水平.该样本数据的总体特征具有岩石样样本的数据特征.该方法还可以对工作区内不同区块分析数据的系统误差进行调平.并以1∶ 25万四子王旗幅为例说明了该方法在这两方面的应用.

| Abstract: | It can be called approximately "deduction" that data of stream sediment samples are converted to the same level in that there is characteristic of data of rock samples.Application of "deduction" is discussed using "conversion method of standard normal distribution".Firstly,data of stream sediment samples and rock samples are all converted to standard normal dis tribution.And then data of stream sediment samples is converted to level of the rock samples.The population characteristic of this data is possessed of characteristic of data of rock sample.This method could also be applied to revise of system error between analysis data of several different sections.Applications of this method in the 1:250000 map of Siziwangqi is introduced. |
