在程序设计中，为完成某-功能所需的一-段程序或子程序;或指能由编译程序、装配程序等处理的立程序单位或指大型软件系统的一-部分。

模块，又称构件是能够单命名并立地完成一定功能的程序语句的集合(即程序代码和数据结构的集合体)。它具有两个基本的特征外部特征和内部特征。

外部特征是指模块跟外部环境联系的接口(即其他模块或程序调用该模块的方式，包括有输入输出参数、引用的全局变量)和模块的功能内部特征是指模块的内部环境具有的特点(即该模块的局部数据和程序代码)。

模块有各种类型，如单元操作模块(换热器、精馏塔、压缩机等)、计算方法模块(加速收敛算法、优化算法等)、物理化学性质模块(汽液相平衡计算、热恰计算等)等。

In programming, a program or subroutine necessary to accomplish a function; Or refers to a program unit that can be processed by a compiler, an assembler, etc., or a part of a large software system.

A module, also known as a component, is a collection of program statements that can be named and complete certain functions (that is, a collection of program code and data structures). It has two basic characteristics external characteristics and internal characteristics.

External features refer to the interface between the module and the external environment (that is, the way other modules or programs call the module, including input and output parameters, global variables referenced) and the function of the module Internal features refer to the characteristics of the internal environment of the module (that is, the local data and program code of the module).

There are various types of modules, such as unit operation modules (heat exchangers, rectification towers, compressors, etc.), calculation method modules (accelerated convergence algorithm, optimization algorithm, etc.), physical and chemical properties modules (vapo-liquid phase equilibrium calculation, thermal calculation, etc.).
