Since Doppler weather radar can detect the radar echo reflectivity factor and the radial velocity of precipitation at the same time, it has considerably deepened our understanding of the physical mechanism of precipitation and the rainstorm dynamics, and can largely improve the warning and nowcasting capacity of rainstorms, hails, squall line and tornadoes with its wide use.

多普勒天气雷达能够同时测量降水的雨强分布和目标的运动速度，使得人们在降水物理和风暴动力学方面的认识有很大提高，它的广泛使用会大大改善暴雨、冰雹、雷雨大风和龙卷等灾害性天气的警戒和短时预报能力。

It is natural that earlier conclusions be revised in light of new information because developing OOT alert criteria is an active and continuing process.

To solve the problem that there is no early-warning technique for conflict management of irregular flight services,the matter element analysis in extension theory was used to build an early-warning model with 5 indices(anticipated delay time,margin of resources,affected passenger number,service ability and event status),each of which has 5 grades(normal,attensional,precautious,danger and crisis).

为解决不正常航班服务管理中无冲突预警的问题，用物元分析方法，建立了以预计延迟时间、运力资源富余度、滞留人数、现场服务能力和意外事件情况为特征指标，以安全、注意、警戒、危险和危机为分类等级的预警模型。鉴于冲突中各种因素相互影响，采用简单可拓关联函数确定模型中的评价权重，并以定量结果确定预警等级。实例验证表明，该模型可用于对服务环境状况的定性评价，或提供定量的预警信息

已建立的S0_2污染物日均浓度的预测预报模型，能根据污染源的状况和天气变化情况及时方便地预测预报大气中S02日均浓度值，这对于避免和减轻危害，保障市民正常的生活以及提供警戒预防措施和为政府决策提供科学信息方面都具有极其重要意义。

But looking from these years's social survival employment environment, the Employer changes job rate already far exceeded 15% guarded, even had some small and medium-sized enterprises presented "a half year royal courtier" the picture.
