So, one of our main objectives of this paper is to survey the recent developments in VaR modeling.

因此本文研究的重点之一是探讨VaR模型的最新进展及模型的适用性。

Especially, we verify that copula method can obtain more practical VaR value than traditional model of multivariate normal distribution.

尤其是验证了借助连接函数理论，能够取得比传统的多元联合正态分布模型更符合实际的VaR数据。

We begin by investigating M—VaR model efficiency when security rates of returns have a multivariate normal distribution.

重点研究了收益率服从多元正态分布的最优投资组合均值—VaR模型在下述三种情形下的有效边缘。

Not only the non-linear dependence between financial markets is able to be caught, but also the more flexible multivariate distribution which can be use to analyze portfolio VaR is able to be obtained from this model.

该模型不仅能够得到金融市场间的非线性相关性，而且可以得到更灵活的多元分布，进而用于资产投资组合VaR分析。

The empirical results show that the FIGARCH model based on the skew student-t distribution is better than other distribution on the assumption in estimating the value of the dynamic Var, because it is better to reflect the risk of actual rate of return and it is proved to be better to choose the skew t-distribution model through the Pearson test.

实证结果表明，基于偏态t分布下的FIGARCH模型测算的动态Var值克服了其他分布假设上的不足，能够较好的反映金融收益率的实际风险，最后在该分布下的Pearson吻合度检验也证实了模型分布选择的正确性。

The photosynthetic parameters of Sinocalycanthus chinensis in both overstory and understory, including the diurnal changes of net photosynthetic rate, intercellular CO2 concentration, dark respiration rate and stomatal resistance, were measured using a LCA4 Portable Photosynthesis System. The photosynthetic parameters of the accompanying plants such as Boehmeria platanifolia, Rhus chinensis and Weigela japonica var.

用LCA4型便携式全自动光合测定仪，在自然条件下，于7月下旬的晴朗天气测定了群落冠层和林下两种不同光环境下夏蜡梅的净光合速率、胞间CO2浓度、呼吸速率、气孔阻力的日进程，并与其伴生植物悬铃叶苎麻、盐肤木、水马桑Weigela japonica var。

Probing and feeding behaviors of the whitefly Bemisia tabaci B biotype on cabbage (Brassica oleracea L.var.caqitata), summer squash Cucurbita pepo L.

利用刺吸电波技术记录了B型烟粉虱Bemisia tabaci在甘蓝Brrassica oleracea L.var.caqitata、西葫芦Cucurbita pepo L。

Second, a portfolio selection model under constraints of both investment chance and VaR is established.

第一章介绍了标准的均值—方差模型及"均值—方差有效集"的性质，给出了投资机会约束和VaR约束的定义。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
