In this paper, the characterization meth-ods on SAMs in recent years by the means of electrochemistry, spectroscopy, micrology and surface wettibility are re-viewed .

本文综述了自组装单分子膜体系的类型和基底表面的处理方法，着重从电化学、谱学、显微学以及表面润湿性等方面综述了近几年来自组装单分子膜的表征方法研究进展，并对其发展前景作了展望。

Carbon nanotubes were discovered by electron microscopist Sumio Lijima at NEC Corp. in Japan in 1991, when he was investigating the residue deposited during a process that synthesized fullerenes (a molecular form of pure carbon noted for its cagelike structures).

碳纳管是由日本nec公司的电子显微镜专家sumiolijima在1991年发现的，当时他在研究合成富氏碳分子（由纯碳原子组成的铁丝笼状结构的分子）工艺过程中沉积的残余物。

These molecules generally have regions that resemble self-antigens – this is the theory of molecular mimicry.

这些分子一般都有类似区域自治抗原-这是理论的分子模拟。

We want to find the local minimus energy ,and MM_PBSA model's free energy.

并找出分子的局部的稳定结构，并使用MM-PBSA估算与其分子其他结构的自由能的差距。

Landmarks such as the virgin-white Dives in Misericordia Church in Rome and the Marunouchi Building in Tokyo were among the first to be coated with the semiconductor, which breaks down organic molecules—including those in grime and pollution—when exposed to light and water and then releases them into the air.

象罗马洁白无暇的仁慈天主教堂和东京的丸之内大厦等标志性建筑，将属于首批运用这种半导体涂料的建筑物。当与 hat中文是什么光和水接触的时候，这种半导体涂料能够降解有机分子－包括尘垢和污染物中的有机分子，然后将它们释放到空气中去。

Two of these protein bands, with a molecular weight of 12 000 Mr and 14 000 Mr, showed immunoreactivity with IgE in the sera from patients with allergy to pollen of Caryota ochlandra. For the pollen extract of Carvota mitis, 30 protein bands were detected in SDS-PAGE, and three of these protein bands, with a molecular weight of 12000, 14000, and 26000 Mr, showed immunoreactivity with IgE in the sera from patients with pollen allergy of Carvota mitis. The 14000 Mr protein was the major allergen. Result from the ion-exchange chromatography indicated that the two pollen allergens (12 000、14000 Mr) from Caryota ochlandra were eluted in the second peak. The major pollen allergen of Carvota mitis was eluted in the forth and fifth peak.

结果 长穗鱼尾葵花粉有30余条蛋白带，其中主要条带有18条，12000和14000 Mr为长穗鱼尾葵花粉特异性变应原；短穗鱼尾葵花粉有30余条蛋白带，其中主要条带有9条，26000、1200和14000 Mr为短穗鱼尾葵花粉特异性变应原，其中14000 Mr为主要变应原；通过离子交换层析方法纯化出长穗鱼尾葵花粉相对分子质量为12000和14000的变应原主要分布在Ⅱ峰中，短穗鱼尾葵花粉相对分子质量为14000阳的主要变应原分布在Ⅴ峰和Ⅵ峰中。

The mean molecular area of mixed monolayers in the experiment is smaller than that of idealπ-A curve at the range of 0.2～0.8 molar ratio.

在摩尔分数0.2～0.8范围内，由实验得出的混合单分子膜的每一个平均分子面积都小于理想曲线；而在0.1和0.9时，则实验值都大于理想值。

In this approach, a small molecule effector moiety is displayed from the surface of the protein, and protein and small molecule act in consort to bind the RNA target.

在此方法中，一个小分子效应基会显示从表面的蛋白质，蛋白质和小分子的行为约束勾勾搭搭的RNA的目标。

An improved hard-sphere model predicted rightly the changing trend of the standard partial molar volume of alkyl chain of amino acids with concentration of electrolyte,and confirmed the assumption that the sum of standard partial molar volume s of CH and CH3 groups is twice as many as the standard partial molar volume of CH2 group.

根据改进的硬球混合物模型，正确预测了氨基酸分子的烃链在电解质水溶液中的标准偏摩尔体积随电解质浓度的变化关系，并证实了"氨基酸分子中CH和CH3基团的标准偏摩尔体积之和是CH2基团标准偏摩尔体积的2倍"这一假定。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
