Results Among 54 WD patients, 36 were found to carry Arg778leu mutation, among whom 15 were homozygote, 21 were heterozygote, the frequency of this mutation was 47.2%. Of 46 patients with hepatic damage, 36 were found to have the mutation of Arg778Leu, among whom 34 were found to have Leu770Leu polymorphism simultaneously.

结果 54例Wilson病患者中36例存在Arg778Leu基因突变，15例为纯合型，21例为杂合型，Arg778Leu等位基因突变频率为47.2 ％；46例伴肝损害的患者中33例存在ATP7B基因外显子8的Arg778Leu突变；36例Arg778Leu突变者中34例同时伴有Leu770Leu多态性。

There was a higher integral of metastasis in E4 genotype group than others, and a lower integral of metastasis in E2 genotype group than others, Multiple regression analysis showed that genotypes were significantly associated with the TC TG HDL levels and integral of metastasis.

ApoE基因多态性对血脂具有显著影响，E3/3基因型的HDL水平明显高于E2基因携带者，且基因型与TC浓度、TG浓度、HDL浓度明显相关。

In chapter 4, in the frame of partially ordered F-type topological space, we research the existence of the solution of a nonlinear operator equation Lx = Nx, and the convergence of the iterative sequence {u_n} which satisfies Lu_(n+1)= Nu_n for a solution of the equation. Then, we give the conditions for multiplicity of the solutions of this operator equation.

第四章，在半序F-型拓扑空间框架下研究一类非线性算子方程Lx=Nx解的存在性，以及满足Lu_(n+1)=Nu_n的迭代序列{u_n}对于方程解的收敛性，并给出这类算子方程具有多解性的条件。

Seven main effect QTLs and 7 digenic interactions controlling heat tolerance during flowering time were detected in two-year experiments.

利用181个在亲本间具有多态性的SSR标记，构建了覆盖水稻全基因组1559.6cM、标记间平均距离为8.3cM的遗传连锁图谱。2年共检测到7个抽穗开花期耐热性主效应QTL以及7对上位性QTL.2004和2005年分别检测到3个和4个QTL，共解释29%和37.3%的表型变异。

Super large type sedimentary hydrothermal sulfide ore deposits, located in middle Qinling and west Yinshan mountains, has shown the multi metal and pyrite type deposit The deposits are shown sililay geo geochemistry characteristics to SEDEX sulfide deposits in middle Proterozoic and Paleeozoic Era in the world, i e , ore forming age were 1 4～1 2 Ga and 0 4～0 3 Ga ore bodies show more than 1 000 m long and multi layered distribution, the ore of sulfide rich show massive band...

地质地球化学特征与世界中元古界和古生界中的SEDEX 硫化物矿床基本相同：成矿时代为1－4 ～1－2 Ga 和0－4 ～0－3 Ga，均产于克拉通边缘盆地中；矿体延长达千米以上，具多层性特征；富硫化物矿石为块状条带状，矿物组合简单，有显著分带性；硫同位素组成为海相硫酸盐型，铅同位素为混合程度较高的均匀性铅等。
