| 摘 要： | 为了研究两指标随机过程的停止问题，Fouque引入了停点的过去，探讨另外几种停点的过去，从而得到了亚强停点的Fouque下确界仍是亚强停点，最后举2个反例说明它的几何下确界不一定仍是亚强停点。

| Abstract: | The pasts of several kinds of stopping points are studied. Some properties of the sub strong stopping point are got. For example: the Fouque infimum of two sub strong stopping points is still a sub strong stopping point. |

| Keywords: | the past of a stopping point sub strong stopping point the Fouque infimum |
