阻抗分析软件ZviewSolartron公司生产的电化学界面配套电化学阻抗谱分析软件的最新版本，可对电化学阻抗谱进行拟合和分析。
广泛用于材料腐蚀科学、电沉积动力学等各个领域。
前些天传了个zview软件，最近又看到很多人在问这个，今天有点时间，干脆简单怎么使用。
1.导入数据注意了, 有人反映显示为演示版无法使用, 其实是自己操作不当造成的! 如果仔细按照图做肯定能用. 今天偶然发现他们的问题出在哪里, 请注意二楼的特别说明!2.数据格式要求：只要是三列数据，如下图：实部、虚部和频率即可；特别注意: 用不同仪器测试时导出的结果, 一般前面都有些题头, 几点一定要删除掉, 也就是开始就是数据3.激活数据：4.删除不需要的数据，也就是zview不能拟合的部分：5.即时拟合(instant Fit)，也就是为后面的拟合获取初值：1）这个需要一个一个元件单独进行，如图中1处所标，选中部分准备进行即时拟合；2）这里忘标了，在左上角打框的地方，点击它就是即时拟合了；3）选择适宜的等效元件，如2处所标识，获得初值6.建立适宜的等效电路，这个取决于自己的体系：7.把1处的数据，用鼠标抓起来，丢到2处去：8.把1处的fixed改称free，为拟合作准备：点击2开始拟合，但在拟合前还有个地方需要部补充一下，因为有张图丢失了，没心情去补，描述如下：这张图左上方有个model，点击进去将mode改为fitting才能拟合。
9.如图，1处是拟合的结果，如果要用数据绘图，则在2处选拟合结果，再点击3处10.这个结果就可以粘贴到origin，excel等里绘制拟合后的图了后记：遗憾的是，我所选取的这个数据有问题，因为仪器的缘故，实部被乘了-1，导致拟合出问题。
很久不作这个了，现在不太喜欢用交流阻抗，因为任意性太大。
故此，提醒各位，慎用阻抗！一定要多测，最好系统地测，得到一组数据再慢慢分析，数据能说明你的问题是好事，不能说明也就不必勉强。
ZSimpWin Version 3.00For Windows 95/98/2000/NTElectrochemical Impedance Spectroscopy Data Analysis Software电化学阻抗谱数据分析软件USER MANUAL用户手册第二版January 15, 2002作者：Bruno Yeum, Ph.D.编译：武显亮，Ph.D.一、何为“ZSimpWin”?ZSimpWin是一个电化学阻抗谱（Electrochemical Impedance Spectroscopy，EIS）数据解析软件。
利用计算机具有越来越快的计算速度，并采用创新的观点，是软件具有如下性能特点。
1．最少量的用户输入：用户只需为阻抗数据列选择合适的模型，即可由ZSimpWin自动执行拟合。
2．自动分析：与所选模型有关的参数由程序自动求得。
ZSimpWin会为这些参数自动设置初值（default：Auto Setup option），然后利用这些初值进行计算，得到结果，然后多次改进计算结果，直到获得满意的为止，然后保存最终结果。
3．处理多任务：设置一个包括多个任务的批处理命令，然后依次处理，分析结果保存在一个指定的文件夹中。
4．以多种方式输出结果：分析结果包括图形、拟合的参数、计算机处理的历史记录等。
任何结果及其组合都可以打印出来或拷贝到Windows剪贴板上。
最好的方式是将拟合参数和显示的图形打印在一张纸上。
5．只需点击鼠标操作：整个拟合过程不需输入任何数字或字符，只要用鼠标进行点击即可。
2二、数据拟合基本原理本章介绍应用非线性最小二乘法拟合原理分析电化学阻抗谱数据以及确定最优参数过程中所遇到的问题。
6．最优化原理用电路元件组成的等效电路来模拟电极动力学。
定义一个与模型参数、实验数据点以及实验数据点方差相关的最优化函数（称作χ2），求解使函数值为最小的参数值。
7．χ2定义模型最佳拟合参数的获得是通过定义为残差平方和的函数（χ2）的最小化来实现的。

In principle, selection of a model is sufficient to define a problem. However, computation must start with certain values of the parameters and proceed by applying an optimization method. Estimated solution depends on the values of the parameters. The desired solution is the one associated with the least deviation and can be obtained by trying a large number of combinations, comparing the deviations, and then selecting the one providing the least deviation. For a complex problem, however, the number of trials is too large to be manageable.The author experienced a lot of frustrations in analyzing data using complex models. With current commercial software in the market, only highly skilled professionals can perform data analysis. They examine data and reduce the number of trials. Satisfactory results are obtained only when the trial values are adequate. For a complex model, determination of these values becomes an extremely difficult task.The fundamental problem is the requirement of data entry for these trials. Development of ZSimpWin started with the idea of utilizing the high-speed of recent computers for these trials. How about asking a computer to try thousands or millions of combinations and to deliver desired results? In practice, the number of trials had to be drastically reduced by imposing various constraints.It took the author about 10 months to develop a program which had the intelligence to Autostart (with no other input from the user) and improve the results successively until satisfactory results were obtained. The author presented this work to Princeton Applied Research in April, 2000. Princeton Applied Research's staff were excited about these results and provided assistance for further improvements.This version was satisfactory in producing desired results, however, required substantial enhancements in graphics and data management to meet the high standards of recent Windows-based applications. In the last 8 months, the author continuously changed the appearance, added more features, reorganized functions, and minimized the number of mouse button clicks by combining a sequence of operations.In the last couple of months, the author devoted much time to implement automatic saving of computational results. Now data analysis process is very simple with ZSimpWin. The user defines a job by specifying a data file and selecting a model, and then requests its execution. ZSimpWin takes over all the complex operations. It autostarts, performs computations a number of times to determine the desired solution, and saves these results. When data analysis is finished, the user examines these results and prepares reports.The ZSimpWin has been created to make EIS data analysis fun and easy. You will enjoy the adventure of data analysis with ZSimpWin.Bruno Yeum, Ph.D.EChem SoftwareAnn Arbor, Michigan, USAFebruary 2001TABLE OF CONTENTSSoftware License Agreement 2 Preface to Version 2.00 3A.

Technical Support 11 Acknowledgments 11A. System RequirementsZSimpWin will run on any IBM PC or compatible computer that supports Windows 95, Windows 98, Windows NT, Windows 2000, Windows Me, or Windows XP. Because ZSimpWin requires a lot of computational efforts, it is recommended to use a high speed (at least 350 MHz) Pentium microprocessor for best results. Additional requirements are:• A minimum of 128 megabytes of memory (RAM).• A VGA display of 800x600 is recommended.• A Windows-supported mouse.B. InstallationZSimpWin is installed to the folder, c:\Program Files\ZsimpWin, as default.Another folder can be selected at the installation stage. This folder is the Application folder.If you are upgrading from an old version (2.00, 2.10, 3.00, or 3.10),1. Uninstall the old version.2. Delete the registration key file in the Application Folder (e.g., C:\Program Files\ZSimpWin\*.key).3. Install the new version.If you are upgrading from V3.20,1. Uninstall the old version.2. Keep the registration key file.3. Install the new version.ZSimpWin is supplied on CD-ROM.1. Insert the disk in the CD-ROM drive.2. Double click the My computer on the Desktop.3. Double click the CD-ROM Drive ("D:", "E:", or "F:" depending on your system).4. Double click “Setup_ZSimpWin_321” to start installation.5. Click on the [No-Questions-Asked-Installation] button to install to the default folder, and follow thenext instructions.UninstallIf a previous version is installed in your computer, remove this version following Windows standarduninstall procedure.1. Click My Computer.2. Click Control Panel.3. Click Add/Remove Programs.4. Select "EChem Software ZSimpWin 3.21" to remove.5. Click on the [Add/Remove] button. The "Confirm File Deletion" dialog box will appear on thescreen. You will get the message, "Are you sure you want to completely remove the selectedapplication and all its components?"6. Click on the [OK] button.Note that all the folders and the files copied during installation of the old version would be completely removed. However, the files you copied for your work or testing would not be removed.C. Naming Files and FoldersSimple folder and file naming rules are used to allow automatic saving of computational results. This section describes the folders containing various types of data and the rules to be followed in the creation of new folders.1. ZSimpWin is installed to C:\Program Files\ZsimpWin\ as default. Another folder can be selected duringinstallation. This folder is the Application Folder. "ZsimpWin.exe", “Zsimp320.hlp”, “Zsimpopt.cfg”, and "ReadMe.txt", are copied to this folder. On registration, a registration key file (*.key) will be delivered from Princeton Applied Research. This registration key file must be copied to this folder. Files in this folder are essential to run ZSimpWin. Other data files are installed to its subfolders.2. Application folder is abbreviated with ... in this program and instructions.3. A file is identified by folder name, file name, and its extension. The extension must have less than or equalto three characters. ZSimpWin uses different extensions to facilitate data management.4. Create matching Data (Input) and Parameter (Output) folders before data analysis, and store results in theData folder. For example, ...\data\my data\ and ...\par\my par\.Impedance data are stored in the ..\data\ folder or its subfolder. The subfolder must have the name...\data\???? data\ where "????" is a alphanumeric character string. Estimated parameters are stored in the ...\par\ folder or its subfolder. The subfolder must have the name ...\par\???? par\. Impedance data and parameter folders with the same "????" are tied to each other.The impedance data and the parameter folders are dynamically changed during program execution. The current status of these folders are saved when ZSimpWin is closed. At the next session, ZSimpWin starts with accessing the names of these folders.D. Folders and SubfoldersThe tree structure of the folders and subfolders created after installation of ZSimpWin is shown below:E.
