在笔者从业这么多年，PCB行业阻抗计算工具都是用Polar公司的阻抗计算工具SI9000,或早期上个版 本SI8000
Prolar是老牌公司，但也不断在推出新的产品，可以进去去了解一下 https://www.polarinstruments.com/
一直以来在我印象里，好东西都是外国公司创造，但近些年推出【中国制造2025】，中国企业崛起，
在一个创新开放的城市，深圳一家创业公司也推出阻抗计算工具了深圳市赛硕尔科技有限公司
大家可以了解一下 http://www.sisolver.com/ 号称阻抗理论计算精度超过Prolar. 支持国产，加油
一.将单个参数改为Model类做为参数传递
原为单个值参数：
改后Mod参数：

三.写Web服务接口
选择性挺多的，可以用WebService,WCF,WebAPI都可能，这里不贴代码了。
四.凝问解答
1.为要什么封装为Web，初衷是什么 ？
初衷是解决客户端没安装SI9000照样可以计算阻抗
现状：每个客户端需要安装安装SI9000工具，没安装不能计算阻抗.基于此问题思考新方法。
解决方式：通过在在服务端安装后SI9000,通过Web接口封装为服务开放出来供客户端都可以调用，
获取阻抗计算结果与反算结果。
2.阻抗计算是调用哪个DLL计算的 ？
调用了：CalcEngineBEMDll.dll 阻抗计算引擎计算，这个DLL在SI9000安装目录里面
3.如果不安装SI9000，工程直接调用CalcEngineBEMDll.dll是否可以计算阻抗呢？
经过笔者测试，不行的，必须安装SI9000才可以，
4.那么安装SI8000与SI9000的CalcEngineBEMDll.dll计算结果是否相同？
阻抗计算结果是有细微不同的，SI8000升级为SI9000有部份接口参数做了少许优化。
5.如果只安装SI8000，却想拥有SI9000的计算结果是否可以呢？
当然可以的，安装S8000后，将SI9000的CalcEngineBEMDll.dll
替到SI8000的CalcEngineBEMDll.dll就可以了
6. 阻抗反算是什么意思?
阻抗反算是：通过指定阻抗值不变，反算出线宽，线距，介质层厚等信息.
7. 阻抗反算计算精度有多高？
精度由反算次数决定+阻抗精确度决定，当阻抗可以调得出来的情况下，
反算次数正常情况下20次，精度可以高达：0.001欧姆
8. 阻抗反算计算的原理是什么？
通过二分折半算法与各参数对阻抗的正反比关系计算得出。
1.折半算法可以baidu.本例子上文代码中也有写。
2.参数正反比关系如下：
9.是否有Prolar SI9000所有图片模型呢？
有啊，这里整理分享如下：

http://pcbren.cn/ShareFiles/ProlarSI9000阻抗模小图jpg无logo.rar
10.SI9000有多少种阻抗模型，每种阻抗模型对应的参考层与参数是怎么样关系？
经笔记整理统计有93种.对应的参考层与参数清单整理如下:
图片太大小， 可以通过如下链接查图片查看
