 解决方案 
To create an inverted mask in code do the following
private function createInvertedMask(mcToBeMasked:MovieClip):void {

        mcToBeMasked.blendMode = BlendMode.LAYER;
        var invertedMask:Sprite = new Sprite();
        invertedMask.graphics.beginFill(0x0, 1);
        invertedMask.graphics.drawRect(640, 395, 630, 395);
        invertedMask.blendMode = BlendMode.ERASE;
        mcToBeMasked.addChild(invertedMask);
    }
To create an inverted mask in the Flash Professional IDE 
Choose the properties panel of the image you want masked, select "Display" -> "Blending" -> "Layer"
Then select your mask, and choose "Display -> "Blending" -> "Erase"
You'll see something like this:
