We found that under acid condition, selenite radical combined with active hydroxide radical and amino-group of chitooligosaccharides to form chitooligosaccharides - Se compound molecule, the remaining group complex interacted with the negative sodium tripolyphosphate via electrostatical interactation to form nanoparticles with the size about 100nm.

通过透射电镜、粒径分析仪等方法表征，发现壳寡糖-硒纳米颗粒平均粒径为100nm左右，在酸性条件下，亚硒酸根与壳寡糖单元上活性羟基和氨基化合，形成壳寡糖-硒复合分子，剩余的基团与带负电的多聚磷酸钠复凝聚，在4℃下能够稳定保存，25℃以上壳寡糖溶胀而致纳米颗粒发生分解。

For the product 〓, the signal for n=2 is much smaller than that for n=1, which may due to the large steric hindrance by the ethanethiol ligands.

其原因很可能是乙硫醇分子体积比较大，所以金属离子结合第二个乙硫醇时，就有很大的空间位阻，以致比结合第一个乙硫醇要难得多，结果n=1～2之间出现明显的强度突变。

As they are abundant,codominatnt,distributed over the euchromatic part of the genome,and have the character of highly polimorphic,microsatellites are useful tools for gene mapping,clinical diagnosis and predicting,paternity or pedigree analysis,evolution study,and marker-assisted breeding.

由于微卫星标记多态性高、重复性好，并且操作简单，因此在基因的定位、人类疾病诊断及预测、亲权分析、品种鉴定、进化研究，以及动植物分子标记辅助选择育种研究等领域中都有着重要的应用价值。

本论文提出采用多相催化剂，以分子氧为氧源，液相条件下的合成路线是提高目标产物选择性的有效途径之一。

It is a key intermediate in the synthesis of material with nonlinear optical properties, functional molecular wires, polymetal heteronuclear complexes containing ferrocenylacetylide.

它是合成具有非线性光学材料、功能化的分子导线、多金属异双核配合物的关键中间体。

Although the pathogenesis is not very clear, new understandings about development of pulmonary fibrosis has appeared in company with impenetration of cell biology research and molecular biology research. In a word, research of pulmonary fibrosis gradually appears to be integrated and multidisciplinary crossover.

尽管肺纤维化发病机制目前尚不完全清楚，但随着细胞生物学和分子生物学研究不断深入，对肺纤维化的发生、发展机制有了许多新得认识，肺纤维化机制的研究正逐渐走向整体化和多学科交叉方向。

Theopportunity of cross linking reaction between the wood of impreg PF resin treated by hightemperature(150℃-160℃)heating and free radical of wood increased.

木材和PF预聚物之间相互作用的机理可能是；①木材自由基活化了PF预聚物分子，产生-C＝O键；②PF预聚物浸注于木材中，经高温(150℃～160℃)加热处理同木材自由基发生各种复杂反应的机会多，形成化学交联。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
