SimpleSlider这个类在官方网站找了半天。。。没找到，自己写了一个，记录一下。

package {
 import flash.display.Sprite;
 import flash.events.Event;
 import flash.events.MouseEvent;
 public class SimpleSlider extends Sprite {
  private var lowValue:Number;
  private var highValue:Number;
  public var value:Number=0;
  private var slider:Sprite;
  public function SimpleSlider(lowValue:Number=0,highValue:Number=0,value:Number=0):void {
   this.lowValue=lowValue;
   this.highValue=highValue;
   this.value=value;
   init();
  }
  private function init():void {
   graphics.lineStyle(1);
   graphics.beginFill(0xffffff);
   graphics.drawRect(-2,0,4,100);

已知ball0质量m0,ball1质量m1,碰撞前ball0速v0,ball1速度v1,求碰撞后ball0速度v0'以及ball1速度v1'

解：由动量守恒得：m0*v0+m1*v1=m0*v0'+m1*v1'....................................1

    由动能守恒得：1/2*m0*v0*v0+1/2*m1*v1*v1=1/2*m0*v0'*v0'+1/2*m1*v1'*v1'......2

    由算式1得：m0*(v0-v0')=m1*(v1'-v0).........................................3

    由算式2得：m0*(v0*v0-v0'*v0')=m1*(v1'*v1'-v1*v1)

           即：m0*(v0+v0')*(v0-v0')=m1*(v1'+v1)*(v1'-v1).......................4

    把算式2和3联立得：v0+v0'=v1'+v1 => v1'=(v0-v1)+v0'.........................5

    把算式5代入算式1得：m0*v0+m1*v1=m0*v0'+m1*(v0+v0'-v1)

                    即：m0*v0+m1*v1=m0*v0'+m1*v0+m1*v0'-m1*v1

    最近看到某位大师关于flash as3的文章，关于高级旋转坐标没有做推导，不是很复杂。。。不过开始把它想复杂了。。。把推导过程写下来了，纪念之
