书中有这样的Ap计算公式:
500) {this.resized=true; this.width=500; this.alt='这是一张缩略图，点击可放大。\n按住CTRL，滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/55/1657601184768124.bmp');}" onmousewheel="return imgzoom(this);">
上式中的
500) {this.resized=true; this.width=500; this.alt='这是一张缩略图，点击可放大。\n按住CTRL，滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/55/1657601184768189.bmp');}" onmousewheel="return imgzoom(this);">代表甚么?
还有:
500) {this.resized=true; this.width=500; this.alt='这是一张缩略图，点击可放大。\n按住CTRL，滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/55/1657601184768263.bmp');}" onmousewheel="return imgzoom(this);">
这个公式中的Bm应该乘以2吧?频率是80K,
看下面的:
500) {this.resized=true; this.width=500; this.alt='这是一张缩略图，点击可放大。\n按住CTRL，滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/55/1657601184768435.bmp');}" onmousewheel="return imgzoom(this);">公式中的ton(开关频率同样是80K)不应该乘以2吧,
再有就是变压器的次级
500) {this.resized=true; this.width=500; this.alt='这是一张缩略图，点击可放大。\n按住CTRL，滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/55/1657601184768562.bmp');}" onmousewheel="return imgzoom(this);">,为什么要12匝并绕,有那个必要吗?
欢迎指正!!!
