But in the + moiety, the three benzimidazole rings shared the whole space equally, the dihedral angel among them is about 120°, just like three fan blades of an airscrew, the molecular structure appear gear-like shape.

X-射线单晶衍射测试、红外、紫外等方法确定了三(2-苯并咪唑亚甲基)胺的Fe和Co配合物的结构，由晶体结构发现金属配位情况不同、配合物在结构上存在着差异，Fe为八面体构型，而Co为三角双锥构型；其次，两配合物中的苯并咪唑环间夹角不同，配合物中包含N2和N4的两个苯并咪唑环间夹角仅为9.41(0.11)，几乎构成一个平面，呈蝴蝶形；后者Co三个苯并咪唑环几乎平分了整个空间，它们之间的夹角约为120，呈三扇叶螺旋桨式构型，为齿轮形。

In chapter 3, the animalcula of Dracaena cochinchinenis's wound were carefully isolated, it also argues the effect of fungi on the formation of the dragon's blood. Moreover, the loureirins of the liquid zymolysis products of some fungi were detected by HPLC, and the relationship between animalcula and the formation of the dragon's blood is further discussed.

第三章详细地论述了剑叶龙血树微生物群的分离、纯化及其对龙血竭形成的影响，并用HPLC对部分微生物的液体发酵产物作龙血素成分的检测，更进一步地了解微生物与剑叶龙血树龙血竭形成的关系。

This dissertation studied the overcompensatory responses of cotton,Gossipium hirsutum L. plants to leaf loss, square loss and cell sap lossand the changes in some physiological and biochemical contents with timein the case of overcompensation. The artificial defoliation, early squareremoval and aphis colonization were used as three types of simulated ornatural herbivory. The target of this study is to elucidate thephysiological mechanism of cotton plant overcompensation for insectherbivory.

本文以棉花为实验材料，采用人工去除棉花一部分叶片、花蕾及接种棉蚜的方法，分别模拟昆虫食叶、食蕾及吸汁为害等三种为害方式，研究棉花对于失叶、失蕾及损失细胞汁液所产生的超补偿作用，及一些生理生化代谢随棉花发育时间进程变化的情形，以期较为系统地从多个方面阐明棉花对于虫害超补偿作用的生理学机制。

Conon, Bishop of Tarsus, though a Tritheist and, with Eugenius, a supporter of John Philoponus before the emperor, disagreed with that writer about the equality of the three Persons of the Holy Trinity, and together with Eugenius and Themistius wrote a book, kata Ioannou, against his views on the Resurrection.

科农，主教大数，但Tritheist ，并叶夫根尼，支持约翰Philoponus前皇帝，不同意这一作家的平等3人的圣三一（见TRITHEISTS ），并连同叶夫根尼和Themistius写道一本书，字约安努，对他的看法的复活。

To study the ecophysiological effects of low temperature stress on podocarpus fleuryi Hickel seedlings, two-year-old seedlings were selected as experimental material. We conducted comparative study. On the one hand, seedlings were separately placed in the plots located at the top, half-way-up and the foot of Jinyun Mountain (different altitudes at Jinyun Mountain led to the difference in air temperature) and subjected to winter low temperature stress. On the other hand, in laboratory, seedlings were exposed to simulated low temperature stress which were artificially controlled .

为了探讨低温胁迫对长叶竹柏幼苗的生理生态影响，本试验选取长叶竹柏的二龄幼苗为试验材料，在试验方法上采取了对比研究方法：一方面，利用缙云山不同的海拔造成的温度差异，分别将幼苗置于山顶、山腰和山脚下三个样地中，进行野外冬季自然低温胁迫处理；另一方面，在实验室中，利用人工控制的不同低温进行模拟低温胁迫处理。

The taxa examined, all of which have simple leaves with entire margins and camptodromous pinnate venation, varied in their secondary venation, which was brochidodromous or brochidodromous to eucamptodromous, the m...

结果表明：含笑属、合果木属Paramichelia和观光木属Tsoongiodendron植物的脉序类型、一级脉、二级脉及其间脉和三级脉等特征表现出较高的一致性，三属间无明显的划分界限；但是，盲脉及其分支、网眼的发育和大小、叶缘末级脉等叶结构特征存在种间差异。

The paper studied the physiological characteristics of the leaves of Cotinus coggygria Royal Purple with different colors in autumn. Three kinds of leaf colors were selected to measure the contents of chlorophyll, anthocyanin, phenylalanin ammo-nialyase activity and the water content in the leaves. The results showed that the leaves exhibited red if it had lower chlorophyll content, higher activities of PAL and higher content of anthocyanin. The green leaves had higher chlorophyll content, lower activity of PAL, less content of anthocyanin.

本研究以美国红栌秋季叶片为试材，选取红色，中间色、绿色三种颜色的叶片，测定其叶绿素、花色素苷、苯丙氨酸解氨酶活性及叶片组织中的含水量，讨论其对美国红栌秋季叶片着色的影响，结果表明：美国红栌秋季叶片中，红色叶片叶绿素含量较低，PAL酶活性较高，花青素苷的含量较高，所以叶色呈现红色；绿色叶片中叶绿素含量较高，PAL酶活性较低，花青素苷的含量较少，所以呈现绿色。

Based on the analysis of the contents of Cu, Pb, Mn, Zn, and Cr in the rhizosphere sediments of Phragmites australis and Scirpus mariqueter at tidal flat in Changjiang Estuary, the following conclusions can be drawn.

长江口滨岸潮滩芦苇与海三棱草根系、茎叶以及根际沉积物中Cu、Pb、Mn、Zn、Cr的含量分析发现，Cu、Pb、Zn、Cr在根系中的含量较高，而Mn在茎叶中的含量达到总量的55%以上。
