The absorption peak and PL emission peak of PPV-PQ in the solid state, were shift to long wavelengths compared to their corresponding peaks in solution due to strong inter-chain interactions and increased coplanarity.

结果显示，由于在固态下存在较强的分子间作用，分子链的共平面性增加，所以PPV-PQ无论是紫外-可见吸收，还是荧光发射光谱，在固态薄膜下都比在氯仿溶液里发生明显红移。

A universal analytic potential energy function is derived using the cosine function with a phase factor,which is suitable to be applied to the interactions between two atoms in a molecule or molecule and ion.5 kinds of common potential curves are obtained by adjusting phase factors.

Experimental result makes clear, the main reason that structure of revulsive bursa bubble alters exterior activator is exterior activator embeds in the double element layer of bursa bubble, the inhomogenous sex that the exterior charge intensity that changed bursa bubble thereby and the exterior activator after embedding distributing in layer of bursa bubble double element.

实验结果表明，表面活性剂诱导囊泡结构改变的主要原因是表面活性剂嵌入到囊泡的双分子层中，从而改变了囊泡的表面电荷强度以及嵌入后的表面活性剂在囊泡双分子层中分布的不均匀性。

The compositions and FTIR spectral characteristics of hydrolysis product were studied using GC and FTIR. The results indicated that ASP3 is a kind of pectic polysaccharide which contained the main part of homogalacturonan fragments as "smooth regions" with galacturonic acid and rhaminose, and rhamnogalacturonan segments as "hairy regions" backbone. Galactose, arabinose, mannose and glucose were linked as arabinogalactan, galactan and arabinan, which were the mainly constitution of the branch.

实验结果表明，ASP3是一种果胶多糖，主要由光滑区和毛发区（富含中性糖侧链的鼠李半乳糖醛酸聚糖）两部分组成：GalA和Rha位于多糖分子的主链，由于Rha含量较低，大部分GalA相连形成半乳糖醛酸聚糖光滑区；Gal、Ara、Man及Glc位于多糖分子的支链，其中Gal以较高的聚合度与主链相连，Ara以还原性末端或低聚寡糖的形式与主链相连或与半乳聚糖末端相连形成阿拉伯半乳聚糖。

The fact that some molecules can rotate the polarizing light is due to their handedness.

P26分子的旋光性是由分子的手性引起的。

Through the development of molecular biology and cell antigen molecular study, immune classification will be more and more important in the process of diagnosis, treating and prognosis of hematological diseases like leukemia, multiple myeloma, aplastic anaemia and paroxysmal nocturnal hemoglobinuria.

通过对细胞抗原分子研究的不断深入，分子生物学等相关技术的发展，免疫学分型在白血病、多发性骨髓瘤、再生障碍性贫血及阵发性睡眠性血红蛋白尿诊断、治疗及预后中必将起到越来越重要的作用。

All these sugars are "hygroscopic," that is they attract and hold onto water, each sugar molecule holding several water molecules.

所有这些糖都是吸湿性的，即它们都能吸附和存留在水中，每一个糖分子都附着几十个水分子。

The hypochlorous acid and hypobromous acid contained in this bactericide bear extremely strong membrane diffusing-penetrating ability for the absence of charge so as to kill pathogens rapidly.

"甲基利"高效植物病害杀菌剂是一种高效广谱、内吸、治疗型杀菌剂、所含的次氯酸分子和次溴酸分子不带电荷，有极强的扩散穿透细胞膜能力，可迅速将病原体杀死，适用于作物各个生长期，特别对各种真菌性、细菌性和病毒性的疑难病害有独特的铲除效果。

The close coupling calculation of rotationally inelastic collision of He with Na_ 2 is first performed by employing a recently computed ab initio potential energy surface.

在已经拟合好的He-Na2体系势能面上，根据原子-双原子分子的非反应性碰撞动力学的相关基本理论，在空间固定坐标系下，采用严格的密耦方法求解了He原子和Na2分子的转动非弹性碰撞动力学方程。

Objective To observe and compare the changes in corneal sensitivity after photorefractive keratectomy and laser in-situ keratomileusis for myopia.

目的 观察和分析准分子激光屈光性角膜切削术(photorefractive keratectomy， PRK)和准分子激光原位角膜磨镶术(laser in-situ keratomileusis，LASIK)治疗近视后角膜知觉的变化。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.
