西太平洋副高、南亚高压、低纬系统、高空急流、低空大风速轴；西风槽和高原槽、低涡、冷锋、青海湖锢囚锋以及中尺度低压、青海热低压、切变线与辐合线、中尺度云团等系统是高原东北部地区大到暴雨的主要相关系统。100hPa上的南亚高压中心强度加强，位置东西摆动预示高原地区将有降水产生，中心强度减弱，降水过程结束。

The severe storms on the squall line had large radar reflectivity and high tops of echoes. There was a divergence at lower level, a convergence at middle level, and a divergence at upper level in the velocity cross section of the squall. The VIL (Vertical Integrated Liquid water) of the storms increased rapidly to a large value, which is a good indictor of hailstorm. When the probability of severe hail is larger than 30% according to the hail index products, a hail storm is very likely to happen. The convergence line in the boundary can trigger and intensify convections.

结果表明：飑线是在有利的天气形势下发生的，飑线上强风暴的强度大、高度高；飑线速度剖面图中显示有低层辐散、中层辐合、高层辐散的特征；垂直累积液态水含量迅猛增加到比较大的数值对冰雹预报有很好的指示意义；在冰雹指数产品中以强冰雹概率大于30%作为冰雹预警门限则有较好的效果；边界层辐合线起到了触发对流和加强对流的作用。

By using global reanalysis data from NCEP/NCAR,the durative of a floating dust over Beijing during 7-10 in April of 2006 was analyzed.It was found that the impact systems of the floating dust weather were West Siberia cold eddy,Okhotsk warm high and Tibetan Plateau high ridge at the level of 500 hPa;the dry-cold air at the level of 700 hPa transferred to Beijing ceaselessly,and the cold advection and baroclinic instability were strong,the gale and dust storm occurred in the strong cold advection area;the weak instability stratification in surface layer and mid-low level in the south of North China resulted in weak ascending air flow,then transported dust particles to Beijing depending on the easterly wind in front of the surface low pressure.

文章摘要：使用NCEP/NCAR再分析资料对2006年4月7-11日北京浮尘天气过程的持续性进行分析，指出此次浮尘天气过程主要受500 hPa西西伯利亚冷涡、鄂霍次克海暖高压以及青藏高原高压脊影响；700 hPa有干冷空气不断向北京地区输送，冷平流和斜压性都很强，大风和沙尘暴发生在强冷平流区域；由于华北南部地区近地面至中低层存在弱的不稳定层结，容易产生弱的上升运动。

Ministry of Land and Resources and the provinces for the Office of Land and Resources macro-management sector, is mainly responsible for formulating regulations and policies, there is generally no specific grant of land control, the real master is granted the right to urban land management departments at the county level, they are representative; and this 2 specifically responsible for the management of the land grant, and one of the main title of the State Council, the executive has a huge difference, mainly affected by two government at the same level leadership, authority and power of appointment are in the hands of the government at the same level the hands of senior management is mainly responsible for operational guidance, this is bound to make land management sector succumbed to the local executive order, and even fewer consider the implementation of national laws and regulations so that the state regulation of the difficulty of increasing the overall national will and national interests are not fully reflected.

国土资源部和省为国土资源的宏观管理部门，主要负责制定法规和政策，一般没有具体的批地控制，真正的主人是权城市土地管理部门在县一级，它们代表；这2专门负责管理土地赠款，其中一个主要标题国务院，执行有很大的差异，主要受两个政府在同一水平上的领导，权威和权力的任命是在政府手中，在同一水平手中的高级管理人员主要负责业务指导，这势必使土地管理部门屈从于地方行政秩序，甚至更少考虑实施国家法律和规章，使国家调控的困难，提高整个国家的意愿和国家的利益没有得到充分反映。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
