Abstract：
ms is the written version of my talk given at the sib Chinese National Conference on High Energy Physics held in Chengde, April 21st to 25th, 1998. A number of striking spin effects have been observed in high energy hadron-hadron collision experiments. Searching the origins of these effects has been and is a hot topic in High Energy Physics. In the past few years, with the common efforts of the experimentalists and theorehans, a large step forward has been made although many questions still remain to be answered. T'hese results show that the study of the origins of these effects can indeed provide useful information for hadron structure and high energy reaction mechanisms. It shows also that these effects themselves can be used as a tool to probe these mechanisms. For example, it has been pointed out that, they may be used to study the properties of reaction of small-x_B virtual photon with hadrons. In this talk, I will briefly summarize the experimental results on these effects and the main conclusions of the theoretical studies, and then make a brief introduction to the main ideas and the results.
