The analysis also indicates that a rearrangement of atoms has occurred in the Si (001) surface and, while a majority of surface atoms form bonds and dimerize, a minority still exist as non-bonding atoms.

本论文对Si（001）2×1表面再构、低能粒子轰击对再构表面的影响以及在Si（111）表面低能沉积类金刚石膜进行了分子动力学模拟研究。

Mass spectrometry results revealed that the pair of eluents respresented a pair of ternary copper complexes with mixed ligands, providing the first experimental evidence. These complexes are diastereoisomer in nature. The optimized configuration of the diastereoisomer was predicted by theoretical calculation.

质谱实验结果表明，拆分组分是一对铜混合配体复合物离子，其中的一个配体是提供手性环境的流动相添加物，另一配体是待拆分物质的某一构型对映体，这对铜混合配体复合物离子本质上属于非对映异构体。

Following host injury, the balance between the epimers and isomers is a determining factor in the overall regulation of hematopoiesis, TH/TH(2) balance, and host resistance to infections and tumor growth.

The results show that B2 phase presents broad fibred shape in the forged rod, and major textures are close to {112}〈111〉and {110}〈111〉; Fibred microstructure in hot-extruded tube becomes fine and fibres have broken, at the same time,{111} orientation of many grains is close to axis direction of tube; Microstructure in cold-rolled tube consists of B2,β-Nb and4Ni2O phases, fibres has heavily broken, which restrains phase transformation during cooling and heating.

结果表明：锻棒中的B2相呈较宽的纤维状，主要的织构组分接近{112}〈111〉和{110}〈111〉；热挤压管纤维组织变细且发生碎化，多数晶粒的{111}取向接近管材的轴向；冷轧管相组成为B2、β-Nb和4Ni2O，纤维组织发生严重碎化，抑制了马氏体相变的进行，{111}〈110〉和{112}〈110〉成为主要的织构组分。

以上的转化证明了配醣基的不同和构型的改变，至少在所研究的一个配醣物的结果来看，对于内醚环形成的构型是没有影响的。

These results, together with the structural elucidation of the purified polysaccharides described above, indicate that the α-glucans in G. lucidum don't have any remarkable immunomdulating activities, but the effects of β-glucans on immune system depend on their glycosyl residue linkages and sugar chain conformation. Further, it is concluded that the 1, 3-linked backbone, relative lower side chain size and substitution, and a high-organized helical structure are the beneficial structural features for the immunostimulatory activity of β-D-glucans. However, the 1, 6-linked backbone may induce the immunosuppressive effect of β-D-glucans.

结合各纯化多糖的结构与构象分析的结果，可以得出以下结论：赤灵芝中的α-型葡取糖不具有显著的免疫调节作用，而β-型葡聚糖的免疫作用则与其糖链结构和糖链构象有密切关系，1，3-连接的主链，较低的分支取代率和较短的支链长度及高度有序的螺旋结构是β-型葡聚糖发挥免疫增强功能的有利结构因素，相反，1，6-连接的主链却可能引起多糖的免疫抑制作用。
