On May 11,2011, the gale and dust weather appeared in Zhangjiakou City. By analyzing the conventional meteorological data, it was found that the gale and dust weather occurred by the combined effect of the cold air splitting from the bottom of the high-altitude cold vortex and the Mongolian cyclone. The strong cold advection in the middle and lower layers provided the gale weather with driving force. The humidity conditions at middle and lower layers in Zhangjiakou City and its upstream region contributed to the weather process. Finally, the strong and wide rise district provided a more favorable power condition for the maintenance and transmission of the dust to the eastern region.

Aiming at the limitation of traditional measuring soil water potential, the paper presents an information system based GSM to real-time monitor data coming from multiple data sources. The monitoring system, which consisted of monitoring center, GSM transmission channel and data detection terminal, was given. The detection terminal included the measuring station and TS-2 negative pressure meter, which was applied to measure soil water potential. Nowadays the system has been successfully applied to drip irrigation in the cotton field on farm in Xinjiang region. The system provides a feasible technology frame-work for collecting and processing wide geographical distribution data in farmland.

With the development of society and the acceleration of urbanization, urban heat island phenomenon is becoming increasingly prominent. In this paper, enrichment capacity of plant light energy is supplemented based on OKe model according to law of energy conservation. By contrasting each component of energy balance equation between the cities and rural areas, the causes for urban heat island are explained.

On July 10,2004,Beijing was hit by the rainstorm that has not been seen for many years,which caused water accumulation in many places of the urban area,power supply interruption in many places,and traffic paralysis for nearly 5 h. On July 12,2004,the rainstorm in Shanghai lasted less than 1 h,but it caused 7 deaths,more than 20 injuries,extensive power outages and traffic paralysis. At the end of 2005,the continuous snowfall in Weihai City of Shandong Province for half a month caused direct economic losses of over 200 million yuan,and the continuous heavy snowfall had a serious impact on people’s lives. From July 17 to 23,2021,Henan Province suffered a rare extremely heavy rainstorm in history,with a direct economic loss of 120.6 billion yuan. Faced with such urban meteorological disasters and other types of urban disasters,combined with the current situation of disaster prevention and reduction in China,what will managers,decision-makers,and experts and scholars think about from them.

In order to understand the climatic change trend and characteristics of thunderstorm in Zhangjiakou City,and provide climate background basis for the thunder prevention and lightning disaster reduction in the region,observation data of the thunderstorm at Zhangjiakou ground meteorological station from 1960 to 2013 were statistically analyzed by linear fitting,climate trend rate,M-K test,guaranteed rate method and so on. The results showed that the average annual thunderstorm days reached 37. 7 d in Zhangjiakou City from 1960 to 2013,and was in the moderate thunderstorm range. In nearly 54 years,thunderstorm day was reducing at the rate of about 1. 21 d /10 a in the city. There was thunderstorm in other three seasons except winter,and thunderstorm frequently occurred in summer. Summer thunderstorm day was reducing at the rate of about 1. 29 d /10 a,which caused the reduction of the annual one. In summer,thunderstorm day of July reduced most significantly. There were two key points of abrupt reduction,which occurred in 1971 and 1998,on the change of thunderstorm days in Zhangjiakou in recent 54 years. The first thunderstorm date had an advancing trend in recent years,while the final date had not an obvious change. The possibility of thunderstorm was very small from late October to next March in Zhangjiakou City. The first thunderstorm date occurred mostly before middle May,and the period from middle and late May to early and middle September was the high incidence of thunderstorm. The thunderstorm occurred mostly in the NW direction,with the least in E and SE directions,and dissipated mostly in SE direction,with the least in NW and W directions.

受冷却剂丧失事故(LOCA)喷放流体冲击产生的保温纤维碎片是安全壳地坑滤网堵塞的潜在碎片源。本文以空气为介质模拟大破口失水事故(LBLOCA)下介质喷放压力场及物理过程,通过高速摄影视频回放及碎片统计,分析双壁盒式保温结构受高能流体冲击时的破坏规律。实验结果表明,内壁为双壁盒式保温模块最薄弱部分;高能流体冲击下,模块连接机构失效使得模块与管道分离,内壁暴露于高速气流中被撕裂引起保温碎片释放。基于保温结构破坏机理分析,提出采用不锈钢捆扎带可有效减小碎片量,并通过实验对改进方案进行了验证。
