Abstract:	本研究透過共通閘道介面(Common Gateway Interface,CGI)，架設一伺服器(server)系統，提供氣、液體物性之查詢與估算，是典型之共通閘道介面在化工業之應用(Common Gateway Interface for Chemical Industry Applications,即CGICIA)。本物性查詢與估算系統以C++撰寫而成，主要查詢與估算的物性包括有飽和蒸氣壓、熱容、黏度、熱傳導係數、擴散係數…等多種性質。系統中建有一物性資料庫，內含有618種化合物之近20項基本物性常數及參數。物性估算所需之參數皆由資料庫中取得並代入相關的經驗或半經驗式中完成計算。物性估算方程式是除了參考“The Properties of Gases and Liquids”by R. C. Reid, J. M. Prausnitz and B. E. Poling 撰寫而成，也引入著名的group contribution method 和group interaction contribution method，選擇性高。本系統架設在IBM個人電腦上，使用PentiumIII-450MHz處理器、256RAM的記憶體並操作在微軟windows 2000 server的作業系統上。測試結果顯示，本系統在物性的估算與查詢具有穩定和即時回應之效果。 This study, utilizing the common gateway interface (CGI), constructs a server system to provide the search and estimation of the properties of gases and liquids. It is a typical common gateway interface for chemical industry application (CGICIA). The property search and estimation system is written in C++ programming language. Major property search and estimation are heat capacity, saturated vapor pressure, viscosity, thermal conductivity, diffusion coefficients and so on. A data bank consisting of 618 compounds with more than 20 basic data or parameters for each compound is built. For property estimation, parameters are retrieved form data bank and plugged into various empirical or semi-empirical equations to complete the computation. Most of the property estimation equations are from“The Properties of Gases and Liquids”by R. C. Reid, J. M. Prausnitz and B. E. Poling. Alternatively, the well-known group contribution method and its modified counterpart group interaction contribution method are included. The system has been tested in an IBM-compatible personal computer with PentiumIII-450MHz processor and 256MB RAM, running on Microsoft windows 2000 server operating system. Performance is excellent for both the property search and estimation. The system is stable and response is prompt.
