            ts = new TimeSpan(0, Convert.ToInt32(tbMinute.Text), Convert.ToInt32(tbSecond.Text));

            this.TopMost = false;

        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            ts = ts.Subtract(new TimeSpan(0, 0, 1));//每隔一秒减去一秒
            btStart.Text = "【" + ts.Minutes.ToString() + "】Minutes
【" + ts.Seconds.ToString() + "】Seconds";
            if (ts.TotalSeconds <= 0.0)//当倒计时完毕
            {
