Five ways on comparing covariance matrix are applied to the Shanghai 50 Indexes Stock Exchange, which are sample covariance matrix, scalar matrix, two-parameter covariance matrix, single index matrix, constant correlation matrix. We adopt principal components method and Markowitz portfolio method to measure stock market risk using VaR, getting the effect of measuring market risk. The result shows that sample covariance matrix and two-parameter covariance matrix could measure market risk more effectively.

Nested PCR analysis and southern hybridization analysis showed that no polymorphism between H.villosa, Pm97034 and susceptible parent Wan7 107 was detected with the clones from 6VS arm, whereas three clones from H.villosa genome DNA: RH42, RH55, and RH66 showed polymorphism. RGA6 cloned from H.villosa genome DNA was characterized identity to NBS, and show high homology to resistance genes as RPM1 and RPP13 in Arabiadopsis, LRR19 in wheat, and I2C-1 in tomato.cDNA library constructed from T.aestivum-H.villosa translocation line Pm97034 was screened by hybridization with RGA6. Four positive cDNA clones were obtained. R3-2-2 showing 60-90% identity with eukaryotic sulfite oxidases contained an open reading frame of 647bp encoding 140 amino acid, and contained a conserved Moco-dimer domain in the ORF. R6-2-2 showed an ORF containing an Euk-porin domain of 279aa with 20-40% identity to the eukaryotic voltage-dependent anion channel proteins. R8-1-1 showed a complete ORF of 1810bp encoding 493aa with 80-90% identity to plant catalases. R9-1-1 showed an ORF containing a BTB/POZ conserved domain of 204aa with 30-70% identity to pox virus and zinc finger proteins. R3-2-2 and R9-1-1 were the first cDNA clones containingconserved domain of SO and POZ respectively isolated from wheat. R8-1-1 contained a complete ORF with 81% identity to Cat-3. Aspects of the role of R8-1-1 may be same with Cat-3, and it would offer the opportunity for improvement of stress tolerance of wheat.

This thesis takes the strenuous search for cultural identity of the Dead family in Song of Solomon as the main line, embarks on the cultural identity of blacks in different periods, connects the pursuit of identity with their history in American society, outlines a vivid historical picture of blacks from the evolution of their identity (from the enslaved black to the emancipated freedman, to the northern migrator and then the youth born in the north), further explores the efforts made by the blacks on their way to seek their national outlets and build their cultural identity in different periods, points out the advantage and disadvantage of their choice, and finally draws to the conclusion that African American should not abandon their national tradition but at the same time they must stand on American society and find a sound integrity of the two cultures.

本论文以托妮·莫里森的第三部小说《所罗门之歌》中戴德家族寻求文化身份认同的艰难历程为主线，以黑人在不同的历史时期的文化身份的选择为切入点，把黑人对身份的探寻与他们在美国社会中的历史文化联系在一起。从黑人身份的演变(从奴隶到被解放的自由人到北方移民者到出生在北方的新一代黑人青年)勾勒出一幅美国黑人百年历史的生动画面，分析在不同时期黑人为寻求民族出路和构建文化身份时所做出的艰苦卓绝地努力和探索。同时也指出了他们所选择道路的利与弊。最后的结论是：在寻求种族出路时既要立足美国现实又不能抛弃种族传统，而应该努力找到二者的最佳结合点。
