Introduction The equilibrium properties of matter may be considered from two points of view:the macroscopic and the microscopic. Thermodynamics is a macroscopic view which describes the behavior of large numbers of molecules in terms of pressure, volume,composition,and exchanges of heat and work.The quantitative relationships between various measured properties are not based on any model of the microscopic structure of matter. On the other hand,quantum mechanics provides a microscopic description for the structure and interactions of molecules. Ideally,we would like to be able to predict the thermodynamic behavior of substances using our knowledge about individual molecules obtained from spectroscopic measurements and from theoretical calculations of wavefunctions.

Statistical mechanics provides the needed bridge between microscopic mechanics(classical and quantum)and macroscopic thermodynamics. Statistical mechanics provides insight into the laws of thermodynamics,and through it we will see heat, work,temperature,irreversible processes,and state functions in a new light.

The Concepts 统计系统的分类 1独立子系统与相依子系统 独立子系统:粒子间相互作用力可以忽略的系统 For example:ideal gas 相依子系统:粒子间相互作用力不可忽略的系统 For example:real gas 我们只讨论独立子系统。 PDF文件使用"pdfFactory Pro”试用版本创建fwm,fineprint..com,cn
The Concepts 一、统计系统的分类 1.独立子系统与相依子系统 独立子系统:粒子间相互作用力可以忽略的系统 For example:ideal gas 相依子系统:粒子间相互作用力不可忽略的系统 For example:real gas 我们只讨论独立子系统。 PDF 文件使用 "pdfFactory Pro" 试用版本创建 fwww.fineprint.com.cn
2.离域子系统与定域子系统 离域子系统:粒子处于混乱状态,没有固定位置 ,各粒子彼此无法分辨。离域子也称为等同粒 子。 For example:gas,ideal gas,是独立离域子系统 •定域子系统粒子有固定的平衡位置,它们运动 是定域化的,对不同位置的粒子可以编号区分 。定域子也称为可辨粒子。 For example:crystal是定域子系统 PDF文件使用"pdfFactory Pro”试用版本创建fm,fineprint.com,cn
