摘要： 《侵权责任法》对高度危险的规定虽然是开放式的，但是在具体适用时缺乏准确、全面、合理的判断标准，导致司法实践中出现了诸多问题。对高度危险的判断应当从外部确定其界限，在内部确定其考量因素。从外部界限来看，高度危险区别于不被允许的危险。在内部考量方面，应当结合不可控制性、非通常性、损害后果的严重性或者致害概率的高度性，以及物品的性状、活动方式等因素进行综合判断。对高度危险的判断不可僵化，应当根据社会的发展通过对判断标准的调整保持动态化。

Abstract: The rules about abnormal danger are open in the Tort law. Because the criterion of judging the abnormal danger for the concrete circumstances is absent, there are lots of problems in the judicial application. Therefore, it is necessary to define the unambiguous, comprehensive, rational criterion. For the judgment of abnormal danger, the boundary should be fixed from outside and the elements should be determined inside. The abnormal danger is different from the danger which is not permitted by law. The elements of judgment include the uncontrolled character, unusual Standard, seriousness of damage or high probability, nature of material and way of activity, etc. They should be considered comprehensively. The judgment of abnormal danger should not be rigid, and keep dynamic state along of the social development through the adjustment of criterion above mentioned.
