摘要
采用量子场论中的泛函积分方法研究金属氢星体模型中的物态性质和物理量的涨落关系,通过固态和液态金属氢的压强导出临界密度表达式.根据金属氢的物态方程研究木星的力学\,电磁学和热力学表观物理性质,研究结果表明在计算木星的质量和密度时可以忽略转动角速度这一因素.声波在星体内部传播时间与金属氢的有效物态参量有关,其时间的比值具有非常小的差别.另外,星体内部磁场涨落比值和温度涨落比值与晶格常数有关,随着晶格常数的变化,温度涨落逐渐变大,磁场强度涨落逐渐变小,结论为研究木星等巨行星的物理性质提供一种可能的研究思路.
In this paper, the functional integration method in the quantum field theory is used to study fluctuation relationship between physical properties and quantities within the metallic hydrogen star model, where the expression for the critical density is derived from the pressure of solid and liquid metallic hydrogens. Based on the equation of state for metallic hydrogen, the apparent physical properties of Jupiter's mechanics, electromagnetics and thermodynamics are studied. The results show that the angular velocity of rotation can be ignored when calculating the mass and density of Jupiter. The propagation time of the sound wave in stars is related to the effective state parameters of metallic hydrogen, and the ratio of time has very small difference. In addition, the ratios of magnetic field fluctuation and temperature fluctuation are related to the lattice constant. With the change of lattice constant, the temperature fluctuation becomes lager and the magnetic field intensity fluctuation becomes smaller. The conclusion of this paper provides a possible research idea to study the physical properties of giant planets such as Jupiter.
