In the Mu Us desert, either vertical distributions of soil moisture isogram before irrigation or vertical distributions of soil moisture isogram after irrigation shows obviously vertical-layered character. When the irrigation is finished 24 hours later, there is little correlation between vertical distributions of soil moisture isogram before irrigation and vertical distributions of soil moisture isogram after irrigation. All of probability distribution of soil water content before irrigation are left-skewed distribution, but some of probability distribution of soil water content after irrigation is left-skewed distribution, some is right-skewed distribution or normal distribution. The distributed pattern shows different between the probability distribution of water depth of rain gauge and that of soil moisture in horizontal section of different depth. There is close correlation between the distribution of water depth of rain gauge and that of soil moisture in horizontal section, but the correlation debases as the horizontal section turns deeper. Also after irrigation close correlation occurs between the distribution of soil moisture of layers bordering upon each other, but which reduces with space of different layers being larger.

在毛乌素沙地，喷灌前后土壤含水率等值线垂直分布均具有显著的垂直分层特征；在喷灌结束24h后，喷灌前土壤含水率的垂直分布与喷灌后土壤含水率的垂直分布间地相关性较弱；灌水前土壤初始含水率的概率分布形态均表现为较典型的左偏态分布，灌后土壤含水率分布形态表现为左偏态、右偏形态或正态分布；雨量筒水深概率分布与土壤不同深度剖面层水平方向的含水率概率分布在形态特征上表现出一定程度的差异，雨量筒水深分布与水平层土壤含水率分布、灌后相邻深度层土壤含水率分布、之间的相关程度较高，其相关性随着剖面深度和层间距的增加而降低。

The results above showed:(1) The cultivars of large-flowered chrysanthemum are widely distributed in Beijing area with plentiful floral types and floral colors;(2) The cultivars with the rare types and colors are urgent for protection;(3) Most of the quantitative characters obeys to the normal distribution,some important traits agreed with skewed distribution.The probability grading can assist quantitative character in establishing new grading standards;(4) Most of qualitative characters is asymmetrical in cultivars,which might be caused by unbalanced differentiation of characters or linkages coming from emphasis characters selection;(5) The floral characters are relatively stable and have comparably large influence on classification,the characters of stipule also have a certain degree of stability and can act as an reasonable supplement for cultivars classification,but the foliar characters have worse stability and can only be recognized as lower level criterion.(6) The genetic relationship among the Flat-petaled group,the Quilled-petal group and the Spoon-petaled group are closest,which followed by the Filiform-petal group because of long-term selection pressure for the specialization of the petal tip loved by most people.The Anemone-petal group has further genetic relationship with these four groups.(7) ISSR molecular marker detection indicates that the proportion of polymorphic loci of lardge-flowered chrysanthemum is higher,in which the Flat-petaled group has the highest genetic diversity level.

综合以上的研究结果表明：(1)北京地区现有大量大菊品种，且花型与花色较为丰富；(2)珍稀花型、花色品种亟需保护；(3)大部分数量性状是符合正态分布的，少数重点观赏性状迫于选择压力呈现偏态分布，概率分级法能够辅助大菊的数量性状建立新的分级标准；(4)大部分质量性状在品种群内的分布是不均匀的，可能是由菊花性状遗传分化的不均衡性或受到选育重点性状的连锁作用而造成的；(5)大菊花部性状相对稳定，对品种分类影响较大，其托叶部分也具有一定程度的稳定性，可以作为品种分类的合理补充，而叶部性状稳定性较差，在品种分类中应作为更次一级的分类依据；(6)平瓣类、管瓣类和匙瓣类的亲缘关系最近，畸瓣类品种花瓣先端特化受到人们的喜爱，长期的选择压力使其区别于3种基本瓣型，而这四种瓣型与桂瓣类在亲缘关系上较远；(7)ISSR分子标记检测表明：大菊品种多态性位点百分率较高，平瓣类品种的遗传分化最为丰富。

This paper examines whether or not stock return responds asymmetrically to monetary policy shocks. We use over-night rate volatility to measure monetary policy and apply Component-GARCH-Constant Jump and ARJI-Trend model to capture expected and unexpected effects of government's monetary policy on the stock return in American, Canada, Japan, and Britain. Considering the non-normality features of these assets returns, this paper use skewed student t distribution to estimate the relationship between the permanent and transitory components of the conditional variance and the frequency and intensity of jump of stock return.

本文探讨货币政策对於股市报酬之影响，选取货币政策代理变数－金融业隔夜拆款利率在分别采用Component-GARCH-Constant Jump与ARJI-Trend模型，并同时考量报酬率呈现非常态之特性，因此采用偏态t分配(skewed student t-distribution)进行估计条件变异数的恒常与移转部份及跳跃机率与跳跃频率，以捕捉政府实施预期及非预期的货币政策对股市报酬的影响，分析在预期及非预期的货币政策冲击下对股市的影响是否存在不同之效果。
