This paper uses mixture density networks to forecast the time-varying conditional density values of financial time series, and puts forth a new numerical algorithm to calculate Expected Shortfall. The application in Hong Kong Hangseng index approves that Value-at-Risk at high probability levels is accurate, and that it also has good forecasting ability in fluctuation. MDNs can effectively describe the empirical distribution of returns and the volatility mechanism, and is a new model for measuring financial market risk.

基于混合密度网络模型估计金融时间序列的时变条件密度，提出采用数值模拟方法计算Expected Shortfall的新途径，对香港恒生指数的实证研究表明，VaR的预测精度在高端分位点较好，模型评估指标反映出预测效果良好，混合密度网络可以有效地描述收益的经验分布统计特征和波动规律，是一种有效的金融市场风险测量模型。

The results showed that extremely cold rain and snow weather of Sichuan Basin was related well to the variations of water vapor、 frontogenetic function of Yangtze River Basin. at the mid-lower level of the troposphere, especially at 700 hPa level, there was water vapor convergence exiting lastly in Sichuan Basin for long time. And the time of convergence of water vapor was congruous with of cold air in Sichuan basin, and provided the water vapor conditions for the occurrence of low-temperature disaster.

结果表明：四川盆地的低温雨雪天气与南来的水汽变化及长江流域的锋生作用有密切关系，在对流层中低层700hPa上，四川盆地长时间存在稳定的水汽辐合区，水汽辐合的时段基本与盆地冷空气活动时间段一致，这为低温降水的发生提供了水汽条件。

We firstly look back thebirth of SD method,and then present the SD scheme presented by Johnson et.al.forlinear problem to explain the basic idea and implementation:At step 1,we change the testfunctionwhere(1,β)t is the streamline or character direction decidedby hyperbolic operator of the continuous problem,therefore the SD method belongs tothe Petrov-Galerkin method;At step 2,we adopt time-space finite element space,whoseelement is only continuous in space variables x but discontinuous in time variable t.

首先回顾了SD方法的产生过程，然后以线性问题为模型，描述了SD方法的基本思想和具体实现：第一步，将标准有限元方法的检验函数ν改成其中(1，β)t是连续问题的双曲算子部分所确定的流线方向。换言之，SD方法是一种Peterov-Galerkin有限元方法；第二步，采用时空有限元空间，其元素关于空间变量x是连续的，但关于时间变量t仅分段连续。

If there were question of the vagaries of many Nominalists, as, eg, that a bilocated person could be living in Paris and at the same time dying in London, hating in Paris and at the same time loving in London, the impossibility would be as plain as day, since an individual, remaining such as he is, cannot be the subject of contrary propositions, since they exclude one another.

如果有问题的变幻莫测的许多nominalists ，因为，例如，在某bilocated人可住在巴黎，并在同一时间内死亡，在伦敦，恨在巴黎和在同一时间，爱在伦敦，是不可能的，将作为中原为一天，由于个人，其余如他的地方，不能得到解决，有待相反的主张，因为他们排斥另一种。

But that the philharmonic orchestra performs everywhere , performing at every time declares all obscurely on the playbill "with being commanded " by Mr. Strauss Strauss, is which one Strauss to appear on the scene , three brothers also to only have that moment mounting a platform in at last knowing just now by after all. On a costume ball in February , 1863, the sponsor announces to audience: The dance party will by Mr. Strauss conductor , because of, three Strausses have all come time the midnight.

施特劳斯乐团到处演奏，每次的演出海报上都含糊其词地宣称"将由施特劳斯先生指挥"，而到底是由哪一位施特劳斯出场，三兄弟也只有在最后登台的那一刻才知道。1863年2月的一次化装舞会上，主办人向观众宣布：舞会将由施特劳斯先生们指挥，因为，午夜时三位施特劳斯都来了。

Cylinder fertilizer feed is adopted. At the same time, disk coverer and double-directioned plow are applied. In this way, ridge forming and fertilizing are completed at the same time. the degree of mechanization is improved greatyly.

在采用圆筒排肥器深施底肥的同时，利用圆盘覆土器和正反双向两铧犁使2次起垄1次完成，解决了施肥机单一施肥，起垄机专门起垄的重复作业问题，使机械化程度大大提高。

At the same time, Yang xunqiao is a veritable "beautiful country town," set off the town of Castle Peak, surrounded by green water, in recent years have built Crape Myrtle Square, ecological Square, mountains roads, experimental schools, Lagerstroemia primary school, cultural center the elderly warm Park, Huimin medical clinics, community medical service centers and a series of symbolic and functional nature of construction projects to improve people's quality of life at the same time, greatly enhanced the quality of urban construction and grade.

与此同时，杨汛桥还是一个名副其实的"全国环境优美镇"，镇内青山掩映，绿水环绕，近年来相继建成的紫薇广场、生态广场、环山公路、实验学校、紫薇小学、文化中心、老年温馨园、惠民医疗门诊部、社会医疗服务中心等一系列标志性、功能性建设项目在改善人民群众生活品质的同时，大大提高了城镇建设的品位与档次。

The electronic heating evaporator in the high-side gravity recirculation system in ANSI/ASHRAE 64-2500 standard is replaced by a new type plate evaporator which is more effcient and energy-saving, because the cold water outlet from the evaporator that is used to heat the cryogen can be used once again to cool the air in the air inlet trunk; an air processing unit is designed in the lab design, so to imitate all kinds of weather in each season in every location of China at any time the test is being made; the data selection system can send all the data in the test to the computer at one time, and to reduce the cost of the test some data which is more stable are read manually through traditional meters if this can not sacrifice the precision of the test.

本文的设计中用效率更高的新型板式换热器代替了原ANSFASHRAE 64——2500标准中压缩驱动循环系统中的电加热蒸发器，加热冷剂后得到的低温淡水还可以用于冷却进气通道中的空气，不仅提高了效率，而且更加节能；实验室方案中增加了空气处理系统，可以实现随时对全国各地各季节的空气状态进行模拟，方便实验的进行；采用数据采集系统将数据整体采集到电脑中方便数据处理，而且对于变化频率不高相对较为稳定的数据采取传统仪表进行人工读数，在保证测试结果准确性的前提下降低了成本。

Studies have suggested: Of every joint curve, the pace of hip joint is smaller and not changing much; The paces of knee joint , ankle joint and tiptoe are obvious in curvilinear motion; Knee joint up to the peak value of pace early , then moderate , ankle and tiptoe nearly reach the pace maximum at the same time during the course of proposing the knee, later dropped rapidly, the tiptoe pace increased but not reached the maximum again at the time of hitting the target.

研究表明：各关节曲线中，髋关节速度较小且变化不大；膝关节、踝关节和脚尖的速度曲线变化明显；膝关节较早达到速度峰值，然后减速，在提膝阶段踝和脚尖几乎同时达到速度最大值，之后迅速下降，在击靶瞬间脚尖速度又增大但没达到最大值。
