heat rise
2.The calculating method of the hydration heat temperature rise in the concrete pour was applied to calculating the hydration heat temperature rise in the concrete wall. In the project, the temperature curve changing with any time at the center or the surface of the concrete wall and its temperature rise distribution curve about the wall thickness at the highest temperature have be calculated.
7.On the basis of the BWR equation of supercritical CO_2,analyzing the compression and throttling expansion process of supercritical CO_2 extraction system in thermodynamic way,we find the reason of instability in the running process of supercritical CO_2 extraction device:the remarkable heat release and temperature rise of liquid CO_2 compressed result in the abnomality running of the pressurization pump;
