甲苯一硝化生成邻硝基甲苯、对硝基甲苯、间硝基甲苯，其中对硝基甲苯和间硝基甲苯的用量明显增加，提高它们在产物中比例的研究，具有十分可观的经济价值，所以本文从工业化的角度出发，通过改变温度和硝硫混酸的组成，分别对提高一硝基甲苯中对、间位异构体的比例进行研究。

They all contain 13 protein coding gene,2 rRNA gene,22 tRNA gene and 1 D-Loop.The base composition for the four nucleotides is A-32.0%,C-27.6%,G-14.7%,T-25.8%,And it is A-32.5%,C-26.9%,G-14.1%,T-26.5%for Yellow-throated Marten.But there are some definite differences in base composition,the using of Initiation codon and Stop codon,and the mode of repeat sequences in control region.The codon usages of Manes have bias,and the ttiird locations of codon of protein-coding genes have the higher frequency in using A and C.There may be some relativity with the content of A and C in D-loop,namely,it has relation with the mode of repeat sequences.The complete mitochondrial genome of the Sable and Yellow-throated Marten were submitted to GenBank,and the accession number are FJ429093 and FJ719367 respectively.3、The complete mitochondrial genome of 6 other species of Mustelidae from GenBank and some sequences of D-loop from the 6 species were aligned.

分析紫貂大兴安岭亚种、长白山亚种、阿尔泰亚种和北欧亚种间的基因流及进化历史得知：大兴安岭种群与新疆种群和长白山种群间的基因流水平最高(Nm=0.1260和0.1427)，新疆与长白山种群间最低Nm=0.0053紫貂种群在进化过程中可能发生过种群膨胀，经历过种群增长过程。2、对紫貂和黄喉貂的线粒体全基因组结构进行分析发现：全长分别为16 523bp和16549bp，均包含13个蛋白质编码基因、2个rRNA基因、22个tRNA基因和1个非编码序列区(D-Loop区，紫貂全序列中碱基组成为A-32.0%，C-27.6%，G-14.7%，T-25.8%，黄喉貂为A-32.5%，C-26.9%，G-14.1%，T-26.5%；基因排列顺序与日本貂和貂熊的一致，但碱基组成、起始密码子和终止密码子的使用及控制区中串联重复序列模式等均存在一定差异。

Moreover, the actual allele frequency of most varieties deviates far from Hardy-Weinberg equilibrium. All PPB、na 、I、h、Gi and Fst have proved to be the references to elucidate that ISSR is a most powerful tool to analyze genetic diversity, compared with the RAPD marker and the allozyme marker is less strong ordinally. We could divided the 70 samples into A, B, C, D and E five groups using three methods according to genetic distance clustering. There is a bit displacement for few varieties in different clustering maps, but the most are similar to morphological analysis despite that there is still a great difference among cultivars in the same one group. The above results imply that the three methods have the different sensitivity and resolution in genetic distance analysis of close varieties. The Mantel test indicates that the results from the three kinds of markers have the significant correlation, which demonstrates that the number of the used three kinds of markers is enough to exactly detect the diversity of all 70 samples to ideal extent. And these methods can be used to evaluate the diversity of the whole group using the miscellaneous samples instead of the individual sample, of the Gerbera jamesonii are mainly from tissue culture plants. In conclusion, the above study results provide a reference for the application of three kinds of molecular markers to molecular marker-assisted breeding of flower. 2. The genetic diversity among the eight introduced cut-flower varieties of Ranunculus asiatica was analyzed by the ISSR markers. Based on the genetic clustering tree, all the colorful flower varieties are clustered into one group, and the white flower varieties into another group. Moreover, among the former group the yellow flower varieties are clustered into one sub-group, and the reddish flower varieties, such as rose color, pink, nacarat, are clusetered into another sub-group.

由三种分子标记的分析结果可以看出，等位基因平均值、观察杂合度、Fis值、Fit值皆较高，表明非洲菊等位基因较丰富，杂合基因偏多，且绝大部份品种的实际等位基因频率在品种内偏离了Hardy-Weinberg equilibrium；PP8、na、Ⅰ、h、Gi及Fst皆表明，ISSR检测遗传多样性的能力最强，其次是RAPD，等位酶最低；根据遗传距离进行聚类，三种方法都把70个品种分成A、B、C、D、E五个大组，每一组中除少数品种发生位移外，大部份品种分类结果相似，且与形态分析结果有相似性，但在每一组中，品种间的聚类差别较大，表明这三种方法在近距离品种间检测遗传变异时灵敏度及分辨力不同；Mantel检测表明，三种标记的分析结果有显著相关性，表明所用的三种分子方法的标记数量已经可以相对无偏地检测到70个品种间遗传变异；非洲菊为组培苗，三种标记的检测结果皆表明，混合样品可以作为个体样品的代表，对整个居群的遗传多样性进行评价；这些研究结果可为三种分子标记方法在花卉分子辅助育种中的进一步应用提供借鉴。

They were divided into three groups:nonfusion, posterolateral fusion and intervertebral fusion. After a long term follow-up (≥2y),their clinical data were reviewed to compared their improvement rate of lower back pain,JOA score , subside rate of disc height and chang rate of superior intervertebral space angle.

Many factors may be involve in the course. To investigate the regulation activity of mesenchymal cells to differentiation of epithelial cells from hair follicle and to study its differentiation property, mesenchymal cells gel was made by nubby dermal papilla cells, free dermal papilla cells, skin fibroblasts. Skin keratinocytes and epithelial cells from hair follicle were inoculated on the gel surface and cultured in air-liquid interface. Three-dimensional model of DPC using to induce epithelial cells differentiation is built in vitro.

The results show that, Au-19.25Ag-12.80Ge brazing alloy is better, its melting temperature range is 446.76494.40 ℃, and the temperature interval between the solidus and the liquidus is 47.64 ℃. When the brazing temperature is in the range of 510550 ℃, the alloy has a good spreadability and wettability with Ni. Interface structure observation reveals that there is one continuous intermetallic layer between the brazing alloy and the base metal Ni when welding. X-ray energy spectrum analysis results show that the intermetallic layer is Ge3Ni5, and because of its brittleness, the overthick intermetallic layer will decrease the shear strength of the welding joint, therefore, the welding technology should be controlled so as to gain an ideal welding interface structure.

研究结果表明：Au-19.25Ag-12.80Ge合金的性能较好，其熔化温度范围为446.76~494.40 ℃，结晶温度区间为47.64 ℃；焊接温度在510~550 ℃范围内时，Au-19.25Ag-12.80Ge钎料合金与Ni基体具有良好的铺展性和润湿性，焊接时钎料合金与Ni基体之间形成了一条连续的金属间化合物层，能谱分析表明该金属间化合物层为Ge3Ni5，由于该化合物较脆，过厚的金属间化合物层使焊接接头的剪切强度下降，故应适当控制焊接工艺以获得理想的焊接界面组织。

Nevertheless, no homologues of typical molecular chaperones have so far been found in periplasm, and the recently reported chaperone activities of periplasmic protein disulfide isomerase and peptidyl pro-lyl isomerase seem to be too weak to satisfy such assumed needs.

虽然膜间质中的蛋白二硫键异构酶和脯氨酸顺反异构酶最近被报导具有分子伴侣活性，但是这种活性的检测使用的不是天然的膜间质蛋白，而且没有捕获到复合物的形成，因此看起来仍不能够满足前面分析的对膜间质蛋白保护的需求。
