由T-、l，6-、1，3，6-、1，4-、1，4，6-DGalp和T-、1，2-、l，3-、1，5-、1，2，5-、1，3，5-Aaraf聚合成的AGI型阿拉伯半乳聚糖、AGⅡ型阿拉伯半乳聚糖、半乳聚糖以及阿拉伯聚糖，构成了HAM-3-Ⅱb-Ⅱ的侧链部分，通过Rha残基的O4位与主链相连。

Ribose/galactose/methyl galactoside importing ATP-binding protein 1 was participated in photosynthates transportation from leaf to grain in early and mid-stages.

分析结果表明，核糖／半乳糖／甲基半乳糖苷运输ATP结合蛋白l在灌浆前中期参与物质向籽粒的运输；生长素响应蛋内IAA27通过调节ATPase活性影响叶片物质运输；N-乙酰谷氨酸半醛脱氢酶在灌浆末期参与叶片的多胺代谢，延缓叶片衰老；谷胱甘肽S-转移酶和Cu/Zn-超氧化物歧化酶在籽粒灌浆后期的植物解毒和防御活性氧伤害中起着重要作用。

Based on interior ballistic theory, an attempt has been made to study the initial variable bullet dispersion of Gatling gun with a basic mathematical analysis model of bullet movement.

针对转管炮发射时身管处于旋转状态的特性，建立了同时考虑弹丸旋转惯性力和科氏力的半约束期内起始模型，分析了惯性力、科氏力在半约束期内对弹丸起始扰动的影响，计算得到了在半约束期运动弹丸的偏角变化规律。

Explicitly, they are consist of three classes: If H is semisimple, then H k* for some finite group; If H is not semisimple and the characteristic of k is zero, then H is isomorphic the dual of the cross product between one so called Andruskiewitsch-Schneider algebra and a group algebra; If H is not semisimple and the characteristic of k is not zero, then H is isomorphic the dual of the cross product between one special algebra and a group algebra.

具体地讲，它们共分三类：①如果H是半单的，则H同构与一个群代数的对偶；②如果H是非半单的并且基础域的特征是0的话，则H同构一个所谓Andruskiewitsch-Schneider代数与一个群代数交差积的对偶；③如果H是非半单的并且基础域的特征不是0的话，则H同构于某个特定代数与一个群代数交差积的对偶。

OBJECTIVE: Three sesquiterpene lactones 1-O-acetylbritannilactone, isoalantolactone and britannilactone were isolated from the roots of Inula helenium and the flowers of Inula japonica. The antitumor activities of the three sesquiterpenoids in the cell lines of HeLa, HEC-1, SHIN3, HOC-21 and HAC-2 were measured, and the relationship between structure and activity and the possible mechanisms were explored.

目的： 观察菊科植物中分离出的3种倍半萜化合物异土木香内酯、1-氧-乙酰大花旋覆花内酯和大花旋覆花内酯对体外培养的人子宫颈癌HeLa细胞、人子宫内膜癌HEC-1细胞、人卵巢透明细胞癌SHIN3及HOC-21细胞和人卵巢囊腺癌HAC-2细胞增殖的影响，研究这3种倍半萜化合物的体外抑制肿瘤细胞增殖作用及其结构与活性之间的构效关系，进而探讨3种倍半萜化合物的体外抑制肿瘤细胞增殖的可能机制。

These phenomena are explained as follows thatduring the hydration of α-hemihydrate gypsum, cations have significance influence on theζpotential of α-hemihydrate gypsum, thereby the dispersed state and the dissolving ratesof α-hemihydrate gypsum are changed. But anions have slight influence because it isdifficult that anions enter the double-layer.

产生这一现象的主要原因是：在α半水石膏的水化硬化过程中，阳离子对α半水石膏的ζ电位产生较大影响，从而改变了α半水石膏颗粒的分散程度和溶解速度；而阴离子很难进入双电层，因此对水化过程的影响较小。

I originally planned to design a true hemispherical shaped canopy, but further investigation revealed that a semi-elliptical shape would provide essentially the same drag as that of a hemispherical shape.

我原本计划设计一个真正的半球状的檐篷，但进一步调查显示，一个半椭圆形状将提供基本相同的拖曳，因为这一个半球形的形状。

And then after another half hourI trained another half hour, and all together I'd trained two anda half hours.

然后我又练了半小时，再加半小时……结果总共练了两个半小时。
