最小二乘法原理在计量测试中的应用

Application of Least Square Method in Measure Testing

在计量测试过程中,为了最大限度地减少测量误差,一般要进行多次测量,使测量方程的个数大于待求参数的个数.应用最小二乘法原理,以为条件,建立了待求量的数学模型.同时,介绍了几种常见的非线性问题的线性化处理方法.

In the measure testing, generally,many measures are carried on in order to reduce measure error to a minimum, and the amount of measure equations are more than that of unknown parameter. On condition that[ vv] = min, method of least squares is applied in this paper, built up mathematics model of unknown number： In the meantime,introduced a few kinds methods, which turn non - linear problem to linear problem.
