This experiment adopted organic solvent extraction step by step,following deproteinization,dialyzation,alcohol-precipitation and layer-separation of dextran,to reveal the unknown effective ingredients in pumpkin,which have influence to blood sugar in normal mice or model mice of diabetes mellitus.

为探寻南瓜中对正常及糖尿病模型小鼠血糖有影响的未知有效成分，本实验依次采用有机溶剂分步萃取、除蛋白、透析、乙醇沉淀及葡聚糖柱层析等分离手段，以小白鼠血糖值作为筛选活性成分的指标，在分离的每一阶段对分离所得各个组分进行活性定量评估，并追踪活性最强的部分，最后分离纯化出降血糖活性最强的组分G———南瓜多糖。

Two major pathways exist in the reactions of Cu〓, Ag〓, Au〓 with ethanethiol clusters, one producing 〓 and the other forming〓.

实验观察到Cu〓、Ag〓、Au〓能结合的乙硫醇数目依次为1～10、1～4、1～2，说明它们与乙硫醇团簇的反应活性逐渐减小；它们与乙硫醇的反应都生成了〓，n的大小按Cu〓、Ag〓、Au〓的顺序逐渐增大，由此推测Cu〓与乙硫醇团簇反应时生成〓为主要反应通道，Au〓与乙硫醇团簇反应时生成〓为主要通道，这两种通道并存于Ag〓与乙硫醇团簇的反应中。

One of the synthetic methods of the MAP is to connect subsequent amino acid one by one with the lysine belonging to the lysine-tree scaffolding. Because of the steric hinderance effect, synthesis becomes more and more difficult. And for so many crippled peptides in the MAP, the reactivity of it is not so good.

将支架结构上的氨基酸作为合成的结合位点，按照常规方法依次进行后续氨基酸的连接，由于空间位阻效应，后续氨基酸的连接困难度增加，八分支肽中的残缺肽较多，由此方法合成的分支肽反应活性较低。

With the deflected succession of aquatic ecotype plant functional group,the dominance of mesophytes and xerophytes increased,while the dominance of aquatic and hygric plants decreased. However,there are only planting crops in the reclaimed wetland. In the composition of plant biotype functional group,the hydrophytes reduced quickly with the deflected succession and the dominance of perennial herbs is mostly marked,and there are only annual herbs in reclaimed wetland. Compared with primary swamp,the species diversity index of meadow is the highest,the swampy meadow follows,and the reclaimed wetland is the lowest.

植物的水分生态型功能群组成随湿地的逆行演替，水生、湿生类植物功能群的优势度不断减少，中生、旱生类植物功能群的优势度逐步增加，而在垦后湿地只有农作物；植物生活型功能群组成随湿地的逆行演替，水生草本迅速减少，陆生多年生草本增加占据优势，而在垦后湿地均为一年生草本；湿地植物物种丰富度、多样性指数由原生沼泽、沼泽化草甸到草甸依次增加，草甸为最大值，而垦后湿地则最低。

The proportion of 0, I , IK HI, IV, V, VI was 5.3%, 9.3%, 20%, 44%, 10.7%, 6.7%, 4% respectively. The result indicated that the predominant pathotype was III and IVin Fujian and Jianxi, the proportion of which was 88%, 50% in turn; II and III in Hubei, the proportion was 70%; no predominant pathotype in Hunan but the sum of proportion of II, III, IV was 55.6% comparing the pathogenicity of Xoc from four provinces.

各型菌所占比例：0型5.3％、Ⅰ型9.3％、Ⅱ型20％、Ⅲ型44％、Ⅳ型10.7％、Ⅴ型6.7％、Ⅵ型4％；4省菌株毒力的初步比较表明，福建、江西以Ⅲ、Ⅳ型菌为主，依次占参试菌的88％、50％；湖北以Ⅱ、Ⅲ型菌为主，占参试菌的70％；湖南没表现突出的优势群，但较强毒力的Ⅱ、Ⅲ、Ⅳ型菌所占比例为55.6％；湖北省内不同稻区，病菌毒力也不尽相同。

The inset images on the right depict, from top to bottom, a computer reconstructed image of what the background blue galaxy really looks like, just the white foreground galaxy, and just the lensed blue background galaxy.

而上面影像右侧的插入图片，从上到下依次是，背景蓝色星系真实看上去的样子，再经过计算机重新处理后的影像、白色的前景星系、以及引力透镜下的蓝色背景星系。

Result The results show that A+T contents of CO Ⅱ genes of Libellulidae are lower (68.6%) in Insecta, which proves Odonata is an original group. Every sequence includes 2 Cys, which differs from the other groups of Insecta. Do not agree with the view of raising Macrominae into Macromidae. Agree with the views of putting both Aeshnidae and Cordulegastridae into Aeshnidea, and raising Gomphidae into a superfamily. Order of the evolution relationship of 5 families is: Gomphidae→Cordulegastridae→Aeshnidae→Corduliidae→Libellulidae.

结果］CO Ⅱ的A+T含量较低(68.6%)，说明蜻蜓目是一比较原始的类群；每条序列均含有2个半胱氨酸，这一点有别于其他类群昆虫；不支持将大蜻亚科上升为科的观点；支持将大蜓科和蜓科归入蜓总科，而将春蜓科上升为总科的观点；差翅亚目5科之间的进化关系由慢到快依次为：春蜓科→大蜓科→蜓科→伪蜻科→蜻科。

On the basis of these, the author studies the following problems and draws corresponding conclusions:(1) By demonstrating physichemical and structural character of loessial soil, the results are obtained that it is having great meaning to utilize widely distributive and profound loessial soil resources to purify sewage for protecting groundwater supplying security.

作者在论文中依次研究了如下问题，并得出了相应的结论：(1)通过论证黄土的物理化学性质与结构特性，得出利用广布而深厚的黄土地层净化污水，以保证地下水的供给安全，这在黄土地区是可行的，并具有重大意义。

These results revealed that the pollen chamber developmental pattern passed through four phases. Firstly, a group of nucellar cells at the micropylar end elongated longitudinally. Thereafter, the uppermost nucellar cells at the micropylar end initiated PCD; and these elongated cells undergoed PCD in a basally and laterally oriented direction to form a cavity.

贮粉室的形态发生可分为4个阶段：最先是位于珠孔端的几层珠心细胞纵向地伸长；接着，珠孔端最顶部的珠心细胞发生PCD；然后，那些已经纵向伸长的珠心细胞向基地和侧向地依次发生死亡，产生贮粉室空腔；最后，珠孔端的珠心表皮细胞发生开裂，形成贮粉室的开口。

The glacial rock surface on the independent hill near Laolinkou Daoban was formed in MIS6. The roche moutonnee in the north of Mountain Tuershang was formed in MIS2. Normally , the distance glacial reached is further and the height of glacial is bigger, the scale of ice age is bigger.

根据三组样品所反映的三次冰期来看，形成于倒数第三次冰期的老终垄的保存，以及形成于倒数第二次冰期的冰川擦痕面的存在，说明最近三次冰期的规模由大到小依次为倒数第三次冰期、倒数第二次冰期和末次冰期。
