事故

Insurance contract is aleatory contract, because whether insurer has the obligation to pay insurance benefit or not and the exact number of it all depend on whether insurance accident occurs or not and the degree of damage. Therefore, applicant can obtain huge amount of insurance benefit when insurance accident occurs, but on the contrary, applicant lose premiums when insurance accident does not occur.

保险合同是射幸合同，这是由于保险人是否负有保险金的给付义务以及应为给付时的具体数额的多少取决于保险事故是否发生及其损害的大小，因此对投保人而言，在保险事故发生时将获得巨额保险金；反之，在保险事故不发生时，投保人即丧失保险费。

This thesis is focused on the study of contingency screening method of power system. The main work fulfilled is as follows. 1 Various performance indexes which represent severity degree of contingencies are proposed and analyzed. These indexes are gotten system state before and after contingency clearing obtained by the means of time domain simulation. They can be computed conveniently and immediately and can meet the need of online transient stability analysis.

With the rapid development of our country's photochemistry industry, the liquified petroleum gas is widely used. However, because of its unique flammable, explosive, virulent physic-chemical properties, it causes a series of burning, detonating accident which has occurred in domestic and foreign, which has caused the giant personnel casualty and property damage. Thus, it has been bad influence to the society. Therefore, it is necessary for the liquified petroleum gas store place to carry on the safety assessment and go on the grave accident sequential analysis research, regarding the effective science forecast, prevention and control significant accident occurrence, so it can reduce or avoid this kind of disaster accidents as far as possible, which has the important theory value and the practice significance for guarantee the liquified petroleum gas store place's safe operation.
