实验了一下这个J版说有问题的电路
以下是引用pcaudio在2005-5-11 9:51:00的发言:
<img src="attachments/dvbbs/2005-5/200551195048983.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/2005-5/200551195048983.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
