摘　　要：在最优化解释程序中,将求岩石矿物成分初始值的问题变成解带约束超定线性方程组的问题,它的求解可归结为解约束极小化问题,线性规划与一维搜索相结合的方法可求得这一约束极小化的准确解,实际应用表明,该方法求得的骨架矿物含量初始值是可靠的。In optimal log interpretation program, the estimate of the initial value of matrix con- tent can be converted to solving overdetermined linear equations with constraint conditions, which can be reduced to minimization problem with constraints. To combine linear programming with one-dimensional search method together can get the accurate results. Field examples indicate that the initial value of matrix content estimated by this method is reliable.
