各种植物花粉外壁超微结构的特征在旌节花属两个组中较一致，但其差异可作为探讨属下种的分类和系统学关系的依据。

Don has often been included in Disporum but recent micromorphological, karyological, phytochemical, and molecular phylogenetic studies indicate that separation of the two genera is appropriate.

Don通常被归入Disporum但最新的微形态学、核、植物化学和分子系统学的研究表明把这两个属分开是恰当的。

My friend，世界只有一个，人类本同属一家，生命的相遇如两颗星星在天际的交辉，本是飘逸而圣美的。

There are two kinds of spinels in a granulite terrain of Yushujgou, South Tianshan Mountain. One occurs in the intermediate and basic granulite units and is characterized by enriched Al and poor Cr, belonging to Al_spinel. In thin sections it shows dark green color and subhedral to anhedral form, and coexists with other metamorphic minerals, suggesting a neogenic metamorphic mineral of granulite facies. The other occurs in the adjacent ultramafic rock unit, belonging to Cr_spinel. In thin sections, it is dark brown in color and is scattered among olivine, clinopyroxene and orthopyroxene as irregular grains, indicating a stable residual mineral in the process of granulite facies metamorphism.

新疆榆树沟麻粒岩地体中发育两类尖晶石：一类见于中、基性麻粒岩体中，其化学成分富 Al贫 Cr ，属铝尖晶石，镜下为深绿色，呈半自形至他形粒状，与其它变质矿物共生，表现为麻粒岩相的新生变质矿物；另一类发育在空间上与麻粒岩体紧密相邻的超镁铁质岩体中，为铬尖晶石，镜下为深褐红色，呈不规则粒状分布于橄榄石、斜方辉石和单斜辉石之间，为麻粒岩相变质过程中稳定的残余矿物。

Both parties were only regional inclusive relationship. There werent subordinative relationship of administration between them.

乡和都分属于两种不同的区划模式，两者只是地域上的包含关系，并没有行政上的统属关系。

Yet, the first results are encouraging: several architectural remains that appear to have belonged to a palace-like building and a fort, tombs, ceramics, seals, and two lists with personal names that date back to the year 170 of the Arsacid era (= 78 BCE).

然而，第一批成果是令人鼓舞的：一些建筑仍然是，似乎已经属於一个宫殿式建筑和要塞，古墓，陶瓷，印章，两份名单，并与个人的名字，可追溯到170年的Arsacid时代（= 78公元前）。

Now over 100 cyclotides have been isolated from about 30 species of Violaceae, Rubiaceae and Cucurbitaceae. Most contributions on cyclotides has been achieved by the groups in Australia, Sweden and USA, and no researches related to cyclotides are reported by Chinese scientists.

所在研究组长期从事植物环肽方面的研究工作，具有较好的研究基础，为了拓展环肽研究范围，本论文选择了两种鲜有环蛋白报道的堇菜属植物三色堇（ Viola tricolor L。

Dialkylamine, which is an e-donor, was introduced at the C(4') or C(7) positions in 3HF resulting in similar ESICT/ESIPT dual emission. Even the net dipole moment, the orientation of which is affected by the CT effect, is expected different. Dialkylamine attached at both C(4') and C(7) positions in 3HF, of which the net dipole moment may be associated with the interplay between two charge-transfer systems, displayed different photo behaviors.

在3-hydroxyflavone的4'及7号位置分别修饰担任电子与体的二烷基胺类，在光谱上会观察到两种不同萤光波长，分别属於ESICT和ESIPT，但若同时修饰二烷基胺类，在不同极性溶剂下，会只有一个 ESIPT 的萤光。

Results showed that planktonic Prorocentrum were assembled to onegroup while benthic Prorocentrum were assembled to another group. The percentagesof the bootstrap values were higher than 95%. The results demonstrated that theplanktonic and benthic Prorocentrum should belong to different genus. Furthermore, the resulting phlogenetic structure showed the percentages of thebootstrap values (98%-100%) of Alexandrium in NJ and ML trees were significantlevers and belong to one group, divergently with genus Gonyaulax.

通过分析 17 种甲藻 18S rDNA 序列构建的系统发育树，营浮游生活的原甲藻在显著水平上聚为一类，而底栖种聚为一类，统计置信度均高于 95％，底栖原甲藻和营浮游生活原甲藻在 NJ 树和 ML 树上均为两个分支，且底栖型的分异速度较浮游型迅速，该结果说明原甲藻属中浮游种和底栖种应分属于不同类群。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
