All results above account for that CO_2 gas in Jiyang Sag have multi origin and mainly abiogenetic, and mantle is the dominating source, a few may come from biogenesis; and in the process of gas pools forming, some mantle CO_2 lost by converted to CH4 or carbonate, some crust CO_2 added into the gas pools; CO_2 gas pools in Huagou district have particular geochemical character, maybe there were some decarbonated CO_2 added into the gas pools, need further research work.

以上种种特征都说明，济阳坳陷非烃类气藏中气体具有多来源的特征，但CO_2主体是无机成因，并主要来自地幔，少量来自有机成因；在成藏过程，幔源CO_2通过转变为CH_4或者碳酸盐岩而丢失了部分CO_2，壳源CO_2和其它烃类加入到气藏中；花沟地区的气体地球化学特征与众不同，可能存在碳酸盐地层变质脱气产生的CO_2的混入，但具体原因尚待进一步研究。

The species diversity of Dipentodon sinicus communities in Yushe National Forest Park of Guizhou province was studied based on the quadrate method. The results showed that Rosaceae, Ericaceae, Betulaceae, Fagaceae, Theaceae, Lauraceae, Caprifoliaceae, Cornaceae were the dominant families in D. sinicus communities of Yushe National Forest Park. In the 10 sample plots, there were 8 which were absolutely dominated with D. sinicus population, the importance value came up to 135.69 on average, and it was far higher than the others. For D. sinicus communities, the abundance index (2.847), Simpson index (0.601), Shannon-Wiener index (1.523), probability of inter-specific encounter (0.601) and species evenness (0.569) of the tree layer were lower than those of the shrub layer (5.580, 0.830, 2.377, 0.829, 0.672, respectively) on the whole. It markedly showed a species diversity characteristic of the mixed broadleaved evergreen and deciduous forest in middle subtropics. In the 10 sample plots, the species diversity level of Q1 was the highest, followed by Q3, Q5 and Q6 was the lowest.

摘要运用样方法对贵州省玉舍国家级森林公园稀有保护植物十齿花群落的物种多样性进行了研究，结果表明：玉舍国家级森林公园十齿花群落以蔷薇科、杜鹃花科、壳斗科、桦木科、山茶科、樟科、忍冬科、山茱萸科等为优势科；10个样地中有8个样地以十齿花种群占绝对优势，其平均重要值高达135.69，远远高于其它种群；十齿花群落乔木层物种丰富度为2.847、Simpson指数为0.601、Shannon-Wiener指数为1.523、种间相遇机率为0.601、均匀度指数为0.569，总体上均小于灌木层(分别为：5.580、0.830、2.377、0.829、0.672)，表现为较明显的亚热带常绿落叶阔叶混交林的物种多样性特征。10个样地中，Q1的物种多样性程度最高，Q3次之，Q5和Q6最小，多样性程度最低，10个样地的物种多样性排序为Q1＞Q3＞Q9＞Q7＞Q2＞Q4＞Q10＞Q8＞Q5＞Q6。

We do not add biocides to Shell Cassida products, because in some food manufacturing areas, such as dairy products, bacteria are an essential step in the production process, and biocides are not desirable.

我们不向壳牌加适达产品添加生物杀伤剂，这是因为在某些食品加工领域，如乳制品加工过程中，细菌培养是生产过程中的一个重要步骤，因此，生物杀伤剂是不合适的。

PAI-3 expression increased in the processes ofKCs differentiation. PAI-3 can incorporate into the cornified envelope andmay promote the differentiation ofkeratinocytes.

人表皮KC分化过程中， PAI-3的表达随着分化的增加而增加， PAI-3存在终末分化KCs角质壳蛋白中，表明PAI-3参与KC分化的作用。

These results showed that thegenetic diversity of Schima superba and Cryptocarya chinensis distributed equally inthe subpopulations and the genetic diversity of Castanopsis chinensis distributedunequally in the subpopulations.

可见荷木和厚壳桂的遗传多样性是较均匀地分布在各个亚种群中，而锥栗的遗传多样性在各个亚种群中分布不均匀，每个亚种群都有自己独特的遗传多样性形式。

These suggest that Pinus massoniana, the pioneer species at early succession stage of forest community, is the plant species adapted to high light intensity, while Cryptocarya concinna, a species at succession climax stage has an advantage in light utility under low light environment.

这说明群落早期演替的先锋树种马尾松属于强阳生性树种，具有适应强光的特点，而处于群落演替项级阶段的优势种黄果厚壳梓则能更加充分利用低光生长环境中的光强，同时也可通过提高电子流向光呼吸分配的比例来避免自然光环境中强光的伤害。

Chitosan is a biopolymer, which contains high contents of amino and hydroxyl active functional groups, can be conjugated with heavy metal ions. And because of its advantages such as nontoxic, no second contamination, easy to depolymerize, it is paid more and more attention by scientific researchers.

壳聚糖作为一种天然高分子化合物，高分子段链中含有-OH、-NH2活性基团，可与重金属离子形成配合物，而且由于其无毒，不产生二次污染，生物降解性好的优点，在废水处理中的应用越来越受到科研工作者的关注。

BACKGROUND: Chitosan and its derivant are environmental-friend natural macromolecular materials, characterizing by great flocculation and adsorption capacities caused by electrophilic group including amino and hydroxyl groups, as well as its long-chain molecular structure. So chitosan is widely used as flocculants in domains of sewage disposal, food refining as well as Chinese medicine purification.

The study indicates that the Pb and Zn ore-forming elements probably come from the basement rocks; The initial Pb isotope could be derived from the crust-mantle mixing in the erogenic belt; sulfur isotope composition is enriched in heavy sulfur that may have come from the seawater sulfate in the synchronous sedimentation; the ore is characterized with REE enrichment, obvious fractionation of LREE and flat-pattern of HREE; ore-forming media is thermal brine fluid; both mineralization temperature and pressure are low; the metallogenic epoch is probably in late Dengying epoch of Sinian period.
