摘要
根据热导式量热计的基本理论导出了指数型热谱曲线描述方程。并采用线性回归,运用最小二乘法,应用C++ Builder开发工具,实现了热谱曲线的模拟,为精确处理热谱曲线,获取输入函数P(t)提供基础。应用该模型对校正及试样热谱曲线进行模拟,其结果与实验值一致。
A simple method for the thermogram simulation, in which a exponential equation of thermograms is built, is described the relation between heat flow and time from laboratory scale heat conduction calorimeters. Two constants of the equation, Cl, C2 are obtained by the linear least squares fit method. The application of the thermogram simulation program made with C++ language illustrated by experiments of calibration and sample measurement.
