玻意耳定律的统计证明

玻意耳定律是理想气体在等温过程中的宏观性质反映,其实质是热力学系统的大量分子在准静态等温过程中做无规则热运动的统计结果.文章用气体分子动理论和理想气体分子模型,运用麦克斯韦速度分布律进行了严格的证明,以便帮助学生从微观的角度更深层次地理解玻意耳定律.

Statistical demonstration of Boyle law

Boyle law reflects the macroscopic property of the ideal gas at isothermal process which is also in essence the statistical result of random thermal motion of lost of molecular in thermodynamic system in quasistatic isothermal process.From the perspective of gas molecular dynamics theory and ideal gas molecular model,this paper aims at using Maxwell velocity distribution law to strictly prove the Boyle law so as to assist students to make deep understanding about the Boyle law from microcosmic aspect.
