G. Tvauri, N. Bakradze, E. Kiziria

摘要:

北京大学生物系统物理系提出了一种测量绝对热容的新方法。格鲁吉亚科学院物理研究所。这是在热脉冲交替传递到电池的同时,差示量热法测量样品和参考电池温差记录的绝对热容的方法。新方法可以同时测定样品池和参比池的热容及其差值。为了缩短建立平衡的时间,采用了电池温差补偿的方法。提出的绝对热容测量方法在虚拟差示脉冲量热计模型中得以实现。该模型允许执行计算的设计的差示扫描量热计-任何热量计的主要部分。

英文摘要:

A new method of absolute heat capacity measurement was developed in the Department of Biological Systems Physics at the E. Andronikashvili Institute of Physics, Georgian Academy of Sciences. This is the method of absolute heat capacity measurement of the differential calorimetric ampoule sample and reference cell temperature difference registration while alternate transferring of heat pulses to the cells occurs. The new method makes possible to determine both the heat capacities of the sample and reference cells and the difference of thereof. The method of cell temperature difference compensation is used in order to decrease in the time of equilibrium establishment. The proposed method of absolute heat capacity measurement was implemented in the model of the virtual differential pulse calorimeter. The model allows to perform calculations of the design of the differential ampoule - the main part of any calorimeter.
