焓的变化 meaning in Chinese

change of enthalpy

the change in heat content is called the enthalpy change, △h.
热焓的变化称为焓变H
The change in enthalpy may be expressed in terms of the specific heats of the phases and the temperature and pressure changes .
热焓的变化可以表达为各相比热和温度压力的变化。
The theoretical analysis and the simulation of the chain structure model indicate that the fluctuations of mass leaving enthalpy close in on that of distributed parameter model with two - order , two - order , and three order precision at the disturbances of heat flow rate , mass entering flow rate , and mass entering enthalpy
理论分析及仿真结果表明，该模型在热流量、入口流量和入口焓的扰动条件下，出口焓的变化分别以二阶、二阶、三阶精度逼近分布参数模型。
