单种的

Each In atom is bonded with one Si atoms and two neighboring In atoms; b The adsorption energy of single In atom on the FHUC of the Si(111)-7x7 is 0.2eV higher than that on the UHUC. As a result, In atoms prefer to enucleate at the UHUC and develop into ordered dots array accordingly.

第一原理计算表明， a六个 In 原子在 Si(111)-7x7表面形成一种扭曲的六边形结构，每个 In 原子与一个衬底 Si 原子及两个相邻的 In 原子形成共价键，这些共价键具有类 sp2构型； b单个 In 原子吸附在 Si(111)-7x7单胞的 FHUC 时的吸附能较吸附在没有层错的一半的吸附能低0.2eV/原子，故而 In 团簇优先在 FHUC 成核生长并进而形成有序的点阵结构。

In over-wintering species experiment, AMF colonization showed significant difference, which was greatiy dependent upon the plant species character.

It is also found that if the monatomic model of Johnson is used the pair potential constructed by the former method can give correct heats of solution.

发现如果采用第三章的模型作为单种原子的埋入原子法模型，则由前者构造的合金对势V〓不能给出正确的溶解热，而由后者构造的合金对势V〓却能给出基本正确的超结构的晶格常数、体模量和结合能。

Their electrochemical behaviors are similar to that of TTF, so they should be good donors for conducting materials. They are novel monosubstituted asymmetric TTF-π-A donor molecules with TTF cores, which should be good donors for molecular conductors or OFET potential application.2. The tuning of the charge-transfer of TTF-PEO by solvent was realized forming the mono- and dication complexes_2CuBr_4 (5) and_2(CuBr_4)_2·CH_2Cl_2·CH_3CN (6) in the triclinic Pīand the orthorhombic Pbca space group, respectively.

同时每种化合物均为单取代的非对称分子，因此该类化合物在非线性光学材料领域可能有潜在的应用。2、通过改变溶剂的方法方便地实现了调节TTF-PEO的电荷转移量为+1和+2，分别合成出化合物_2CuBr_4 (5)和_2(CuBr_4)_2·CH_2Cl_2·CH_3CN (6)，晶体结构分析表明它们分别属于三斜的Pī和正交的Pbca空间群。

The main results are listed as following: 1. Phylogeographic study on Croomia The relationships and distribution of cpDNA haplotypes suggested that Croomia had been widely distributed in ancient eastern Asian and northern American; the origin and distribution center of Croomia were concentrated on the mountains comprised Mt.

Croomia亲缘地理学根据叶绿体DNA(trnL-F、atpB-rbcL)单倍型的关系和分布推测，Croomia在古欧亚大陆和古北美大陆有着较广泛的分布；我国的黄山和天目山一带是Croomia的分布、起源中心，其散布路线是从中国大陆到日本，再到美洲古大陆；北美种群与东亚种群分离较早；东亚种的分化时间比较晚。

Cephalomappa sinensis is a monotypic genus ever-green tree endemic to the calcareous mountainous region in southwest of Guangxi Zhuang Autonomous fresh branches are used as feeding stuff for cattle,horse,sheep,and can make them find the possibility of developing feed additive or medicine for livestock,the chemical constituents from this plant were chemical constituents of its roots had been reported in our earlier continuation of our investigation on the branches of Cephalomappa sinensis,a new norneolignan,named Ceplignan(1),was isolated from ethanol extract through column structure was elucidated on the basis of spectroscopic evidence.

肥牛木(或称肥牛树，Cephalomappa sinensis)为大戟科一单种属植物，为常绿乔木，其分布区狭窄，仅限于广西西南部石灰岩山地[1]。肥牛木为优良木本饲料树种，是牛、马和羊的好饲料，用该植物饲养牛，可使牛肥壮，故有肥牛木的名称[1]。研究其化学成分，目的在于探讨开发饲料添加剂或兽药的可能性。我们曾报道了肥牛木根的化学成分[2，3]，在对其枝条的进一步研究中，又分离得到一个新的降新木脂素，命名为肥牛木素。本文报道其分离方法和结构鉴定结果。
