We investigated alcohol, acid, amine, ester and several kinds of normal metal clusters by using the HF-LCAO-MO method for the lubricate mechanism of different polarity bases, through the frontier orbital energy levels and its composition.

用HF-LCAO-MO方法计算醇、酸、胺、酯4类油性剂和常见金属的原子簇模型，从前线轨道能级、分子轨道组成等方面研究了不同极性基团的润滑机理。

In this study, the author used GISH technology to analyze the material that was resistant to take-all in test, and got three chromosome arm addition lines that carried the resistance genes derived from the amphiploid of Triticum-Haynaldia. The above arm addition lines and their resistant and sensitive parents were analyzed by RAPD method and two specific molecular markers that were tightly linked to resistant gene were obtained.

本研究先用基因组原位杂交对经鉴定抗全蚀病的材料进行分析，检测出三个抗性源于簇毛麦的端体异附加系材料，再利用RAPD方法，对这三个材料和抗感病亲本进行分析，得到了两个与全蚀病抗性基因紧密相关的特异性RAPD标记。

Surface activities and colloidal properties of amphoteric surfactants were introduced and relationship of concentration and cluster structure of amphoteric surfactante was given.

介绍了两性表面活性剂的表面活性和胶体性质，给出了浓度与表面活性剂团簇结构之间的关系。

Order in which they are expressed from anterior to posterior in the developing embryo .

这类基因常常成簇出现，在胚胎发育过程中，其活化顺序与生物纵轴的空间表达时相相符。

Beautiful Ting grows Yu Xie normally, grow 35 ～ 100cm; Raceme grows 25 ～ 40cm, have most flower, 8 bunch give birth to 3 ～ at luxurianting an armpit inside; Bud piece small, bristle shape; Perianth piece quadrature circle or rules round form wrap around needle form, long make an appointment with 3.5mm, purple; Filament is long make an appointment with 1.5mm; Antheral grow 1.5 ～ 2mm; Ovary is close globose, style is long make an appointment with 2mm, post 3 crack.

花葶通常长于叶，长35～100cm；总状花序长25～40cm，具多数花，3～8朵簇生于苞片腋内；苞片小，刚毛状；花被片矩圆形或矩圆状披针形，长约3.5mm，紫色；花丝长约1.5mm；花药长1.5～2mm；子房近球形，花柱长约2mm，柱头三裂。

Many research data showed that VP1 gene contains major antigenic determinant of FMDV and is easy to be variable.

研究表明，VP1基因是FMDV的主要抗原决定簇，它具有极高的变异性。

And there are five antigenic sites mapped on the HA.

HA一般含有五个抗原决定簇，流感病毒的流行与其抗原结构的变化密切相关。

The gene mutation resulted in the functional sites changed in some sequences and did not influence the antigenic determinants.

基因突变造成4条序列在功能位点数量上减少，但未影响抗原决定簇。

This caused the decrease in the free energy to the formation of apatite nuclei.

形成的磷灰石是纳米级微晶，局部的团簇有一定的择优取向。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
