MFC繪制阿基米德螺旋線
阿基米德螺線也叫“等速螺線”。
當(dāng)一點(diǎn)P沿動射線OP以等速率運(yùn)動的同時(shí)，該射線又以等角速度繞點(diǎn)O旋轉(zhuǎn)，點(diǎn)P的軌跡稱為“阿基米德螺線”。直線旋轉(zhuǎn)一周時(shí)，動點(diǎn)在直線上移動的距離稱為導(dǎo)程用字母S表示。近似畫法：（1）先以導(dǎo)程S為半徑畫圓，再將圓周及半徑分成相同的n等分；（2）以O(shè)為圓心，作各同心圓弧于相應(yīng)數(shù)字的半徑相交，得交點(diǎn)Ⅰ、Ⅱ、Ⅲ、…Ⅷ各點(diǎn)，即為阿基米德渦線上的點(diǎn)；（3）依次光滑連接各點(diǎn)，即得阿基米德螺線。
