Strong.as，34 行 Warning: 3596: 变量定义重复。 高人帮忙给看一下吧

package fl.transitions.easing
{

public class Strong extends Object
{

public function Strong()
{
return;
}// end function

public static function easeOut(param1:Number, param2:Number, param3:Number, param4:Number) : Number
{
var _loc_5:* = param1 / param4 - 1;
param1 = param1 / param4 - 1;
return param3 * (_loc_5 * param1 * param1 * param1 * param1 + 1) + param2;
}// end function

public static function easeIn(param1:Number, param2:Number, param3:Number, param4:Number) : Number
{
var _loc_5:* = param1 / param4;
param1 = param1 / param4;
return param3 * _loc_5 * param1 * param1 * param1 * param1 + param2;
}// end function

public static function easeInOut(param1:Number, param2:Number, param3:Number, param4:Number) : Number
{
var _loc_5:* = param1 / (param4 / 2);
param1 = param1 / (param4 / 2);
if (_loc_5 < 1)
{
return param3 / 2 * param1 * param1 * param1 * param1 * param1 + param2;
}
var _loc_5:* = param1 - 2;
param1 = param1 - 2;
return param3 / 2 * (_loc_5 * param1 * param1 * param1 * param1 + 2) + param2;
}// end function

}
}

最后一个方法里面有两个声明
var _loc_5:* = param1 / (param4 / 2);

var _loc_5:* = param1 - 2;

我不会~~~但还是要微笑~~~：）
