摘要
本文根据液体的压缩特性,在一定假设基础上,得到了一个适用于高压范围的新的液体等温状态方程 V=A/(P+C),式中 A,C,n 为常数.对水、重水及汞的液体体积的计算结果表明,在压力为1～12000atm 范围内,计算值与实验值之间的一致性令人满意,计算结果的最大误差仅0.058%.
According to the characteristics of liquid compressibility,a new isothermal equation of state is proposed which can be used to calculate the volume of liquids at differant pressures V= (A/(P+C)~n),where V is the volume,P is the pressure,A,C and n are constants.The calculated results show that the results calculated agree with the experimental values satisfactorily,and the maxinmum relative deviation from the experimental value is 0.058% for water,heavy water and mercury with pressure up to 12000atm,and have an advantage over the Tait equation.
