已作了阻抗校准,但还是那样,昨天晚上最后一次测量时阻抗最低值竟然达到9欧,肯定是错误的,今天晚上好好检查套件

测量套件今天好像有问题，新测量的501阻抗图如下：<img src="attachments/dvbbs/2005-3/20053623494269.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-3/20053623494269.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/2005-3/20053623500393.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-3/20053623500393.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
最低阻抗值跟昨天的不一样，1875的散热器发热（以前不知道是否这样），
我发现重物粘贴好不好有相当影响。

梦版，非常感激,忙了告诉你，这二单元震动面积
501：震动直径：10.4cm,
国光:振动直径：13.4cm,
请帮我再算算?
另外,我用万能表(带电感功能)测出501a的电感是0.482,请问上图是501a还是501b?
你说的曲线带毛刺,我今晚再试试,

将阻抗文本文件导出后通过WORD,记事本及写字板转变成zma文件，在sw软件中调用就可以了，不知道这样对不对，明天继续学习，不过测的国光阿VAS是11.89升，令我狐疑，明天用封闭箱再测阻抗曲线，

梦版，前段因套件调得不好，现经你指导下已正常测阻抗。图和文件如下，请帮我再看看和推算一下t/s参数，这一次和上一次好像大有不同。

用lsp软件模拟国光，求阻抗补偿电路，我调出来是11欧+14.74uF，许多书说的是8欧，这11欧有问题吗？梦板帮我看看，这是国光最新不上箱阻抗文件。

用sw推算，有一些差异，不知为什么？应该用密箱会准一点。
