量热仪瑞-方公式解读和一种新的升温曲线数学模型

Discussion on the Rayleigh formula of calorimeter and a new temperature rising model

介绍了瑞-方公式作为发热量测定中冷却校正值的经典算法，从解析函数的角度推导瑞-方公式。在对传统公式进行反思的基础上，结合物理背景提出一种新的量热仪内筒升温曲线数学模型，并进一步给出了模型解析函数的相关计算方法。

In thispaper, the Rayleigh formula was introduced as classical algorithm for the cooling emendation in the determination of calorific value, which could be deduced from analytic function. Based on the deep analysis of classical formula, a new temperature rising model of inner tank of calorimeter combined with physical background was presented, and further more, the related calculation method for analytic function of the model was put forward in this paper.
