摘要
采用化学热力学状态函数法,根据真实气体范德华状态方程式和气体恒压比热关系式,导出了氧弹内真实气体的恒容比热关系式。在此基础上,进一步导出了恒容条件下氧弹内试样完全燃烧后形成物系的热平衡方程式,据此计算出了两种条件下氧弹内的热力学极限状态,探讨了提高燃料热值测定的准确度和安全性的几种途径。
By way of the chemical thermodynamic state function and based on the Van Der Waals' gas state equation and the relational expression of specific heat at constant pressure, the relational expression of specific heat of real gas at constant volume in the oxygen bomb is inferred. The limit thermodynamic states in the oxygen bomb under two conditons are calculated. A preliminary study is made for improving the accuracy and safety in determining the caloric value of fuel.
