[讨论]为什么设置的数值在优化过程中还会改变2

<P>见附图<img src="data/attachment/forum/dvbbs/2005-7/200571415413592340.bmp" 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(\'data/attachment/forum/dvbbs/2005-7/200571415413592340.bmp\');}" onmousewheel="return imgzoom(this);" alt="" /><br></P>
<P>没有设变量怎么也会变呀，只是在原结构上再加一片镜片，就出现了星号，这星号也没办法去掉，优化时莫名其妙的发生了变化</P>

<P>呵呵，设置了自定义semi-diameter当然有*号了；表面孔径的大小可以在表面属性里通过设置Aperture类型和大小来实现，也可以通过设置表面的半孔径为(Fixed)类型来定。表面有了固定的孔径大小就会出现*.</P>
