本文主要介绍有机物性估算系统ＯＰＥＳ（ＯｒｇａｎｉｃｐｈｙｓｉｃａｌＰｒｏｐｅｒｔｙＥｓｔｉｍａｔｉｏｎＳｙｓｔｅｍ）微机版本的软件特性。ＯＰＥＳ的总体结构采用将输入、输出与物性估算程序完全分离的策略：实现了系统的有效分解；物性估算程序的进一步分解则有效地解决了在ＤＯＳ环境下开发大型应用程序所面临的内存使用问题；标准化模块的设计思想既提高了软件的开发效率，又方便了今后软件的维护。本文从基础物性数据库检索方法的选择、用户界面的灵活性与智能性、系统的透明性、系统的健壮性等方面介绍了ＯＰＥＳ的使用功能。＊Ｃｏｍｐｏｎｅｎｔ：１＊２４Ｏ５Ｃ３Ｈ３Ｎ１Ｏ７－１３－１（依次是：丙烯腈的ＩＤ号、分子式、ＣＡ登录号）ＣＨ２＝ＣＨＣ＊Ｎ（丙烯腈的ＯＣＳＣＥ线性码）ａｃｒｙｌｏｎｉｔｒｉｌｅ（丙烯腈的英文名）Ｔ２（温度点数为２，温度分别是２９３。１５Ｋ，４５０．００Ｋ）２９３．１５Ｋ４５０．００ＫＰＯ（没有输入压力，压力点数为０）ＰＨ２（相态为液态）ＰＯ３（极性类别是强极性）ｂａｓｉｃｄａｔａｏｆｃｏｍｐｏｎｅｎｔＮｏ．１（从基础数据库中查到的数据）ＳＴＲＣＨ２＝ＣＨＣ＊ＮＲＭ５３．０６００（ｇ／ｍｏｌ）Ｓ（分子量，质量码Ｓ?
This article introduces the organic properties of the OPES (OrganicphysicalPropertyEstimationSystem) computer version of the software features. The overall structure of OPES adopts the strategy of completely separating the input, output and property estimation procedures: the system is effectively decomposed; the further decomposition of the property estimation program effectively solves the memory usage problems faced by large-scale application development in DOS environment ; The standardization module design not only improves the software development efficiency, but also facilitates the future software maintenance. This article introduces the use of OPES from the selection of basic physical database retrieval methods, the flexibility and intelligence of the user interface, the transparency of the system, the robustness of the system. * Component: 1 * 24O5C3H3N1O7-13-1 (followed by: acrylonitrile ID number, molecular formula, CA accession number) CH2 = CHC * N (acrylonitrile OCSCE linear code) acrylonitrile T2 Temperature point is 2, the temperature is 293.15K, 450.00K) 293.15K450.00KPO (no input pressure, the pressure point is 0) PH2 (phase is liquid) PO3 (polarity type is a strong polarity) basicdataofcomponentNo. 1 (data found from the basic database) STRCH2 = CHC * NRM53.0600 (g / mol) S (molecular weight, quality code S?
