1 把三個壓縮包解壓到同一個Ubuntu文件夾CEAexec下

2 設置環境變量（這步很重要！）

PATH=$PATH:~/Downloads/CEAexec/

不設置環境變量的話，運行程序會提示不能執行FECA2。其實可執行文件FECA2已經在當前目前下了，但是不設置環境變量程序找不到這個可執行文件。

3 運行./runCEA.sh

A) The CEA GUI Download consists of the following files:

1) CEAgui-jar.zip - CEAgui JAR file:
If you have previously installed CEAgui Package , then update to a NEW
version of CEAgui by downloading the newest JAR file (CEAgui.jar).

2) CEA+Fortran.zip - CEA Fortran Package consists of the Source code, Libraries, and examples files.
If the Fortran files(cea2.f, cea.inc, syntax.f, b1b2b3.f) must be
recompiled on your local machine, then the Fortran executable files for
cea2.f, syntax.f, b1b2b3.f should be renamed as FCEA2.exe, syntax.exe,
b1b2b3.exe respectively. It included the CEA related packages - CAP, PAC, MISC.

3) CEAexec-win.zip - CEAexec Package consists of the following files:
b1b2b3.exe, syntax.exe - The executables for CEAgui.
FCEA2.exe - The executable for cea2.
thermo.lib, trans.lib - The cea2 Fortran library files
ceaguiDownload-win.htm - The web page for download.
Readme_CEAgui-win.txt - The file you are reading.
CEAexec-win.bat - run CEAgui using this Batch File

The batch files must contain the following line:
java -classpath "CEAgui.jar" CEAgui

4) If your local system has not installed the Java SE Development Kit (JDK), you must
install the Java SE Runtime Environment(JRE) which consists of Java Virtual
Machine, the Java platform core classes, and supporting files. It is the runtime part of the JDK.
You always download the latest releases of JDK or JRE from the Sun Microsystems at
http://java.sun.com/javase/downloads/index.jsp

B) The CEAexec Package installaton procedures for Windows:

1.Create the installation Directory on your local machine (e.g. mkdir C:\CEAexec)
2.Download all three ZIP files and the executable file into the SAME directory
(e.g. cd C:\CEAexec)
3.Unzip the Fortran Source Code (CEA+Fortran.zip) and save into the SAME directory.
4.Unzip the CEA GUI Execution file(CEAexec-win.zip)and save into the SAME directory.
5.Unzip the CEAgui JAR file (CEAgui-jar.zip) and save into the SAME directory..
6.Double-click on the file (jre-6u5-windows-i586-p.exe) to install
Java Runtime Environment(JRE)by using the system DEFAULT directory
(e.g. C:\Program Files\Java\jre1.6.0_05)
7.Execute the batch file (CEAexec-win.bat) for using the file CEAgui.jar.
Try examples by selecting "Open Examples" from the "File" Menu and choosing an example.
Then select "Run CEA2 Executable" from the "Activity" Menu.
