摘　　要：提出了一种用于间接测量系统的测量函数建立方法。它以n阶线性常系数微分方程的广义函数通解作为测量函数模型。根据系统的测量数据,从通解中自适应地确定与测量数据相吻合的测量函数表达式。并用一组数据建立的测量函数表达式证明,它是对测量数据更具有适应性的实用方法。A method for constructing the measurement function expression to an indirect measurement system is proposed, in which the general solution of the n-order linear ordinary differential equation with constant coefficient is used as a function model of the measurement function expression. Depending on the measured data from the system, the measurement function expression in correspondence with the data is derived from the general solution self-adaptively. The constructing indirect measurement function expression using a group of data is more adaptive to the measured data in practice.
