            //a.AccelerationRatio = 0.33;//加速阶段从时间百分比0%到33%

            //a.DecelerationRatio = 0.33;//减速阶段从时间百分比100%-33%到100%；

            //a.IsCumulative = true;//仅与RepeatBehavior一起使用在a.By下50-150-50跳150-200-150

            //a.IsAdditive = true;//获取属性默认值，从默认值开始动画

            //a.FillBehavior = FillBehavior.Stop;//动画完之后恢复原始值

            //a.From = 50;//起始，若默认值不是50则跳到50在进行动画

            a.AutoReverse = true;//往返

            //a.To = 100;

            a.By = 100;//等于a.To = 100 + a.Form;

            b.BeginAnimation(Button.WidthProperty,a);//调用开始
