| 摘 要： | 对上海80家跨国经营企业的抽样调查显示,上海企业在国际经营过程中对东道国政治风险的认识和抵御能力有待进一步提高。这从一个侧面反映出我国跨国经营政治风险法律保障制度滞后、跨国经营政治风险宏观管理制度无序、企业内部政治风险监管制度不健全等突出问题,必须从政府和企业两个层面着手加以解决。

| Abstract: | The IEEE802.11 DCF (Distributed Coordination Function)and three methods for its capacity analysis are introduced. According to analysis and simulation results, the relationship between IEEE802.11 DCF capacity and active nodes is studied, and the conclusion is drawn that the reason why network capacity is not ideal when there are too many or too small active nodes lies on the limitation of the current backoff algorithm and it needs further improvement. |

| Keywords: | Network capacity DCF Active nodes Backoff algorithm |
