地球化学计算中误差传递分析的应用

通过两个实例讨论了地球化学计算中的误差传递问题,对照了四种不同方法的潜力和限制,拓广了蒙特卡洛方法在相关变量分析中的应用,指出其在不同条件下总能用有限机时逼近合理结果,揭示出协方差矩阵法的特殊效益,可相对于独立初始变量展现中间变量的相关关系。

APPLICATIONS OF ERROR PROPAGATION ANALYSES TO GEOCHEMICAL CALCULATION

Two examples are given for comparing applications and limitations of four methods which can be used to deal with error propagation in geochemical calculations. The examples indicate that the Monte Carlo method can also be employed to evaluate the effect of covariance. A special function of the method for covariance matrix shown here can reveal the correlations of middle variables relative to the independent primary variables.
