近晶 meaning in Chinese
smectic
Examples
- Smectic liquid crystal
近晶相液晶 - Thirdly , order parameters , , of smectic - a phase can be expressed as this two kinds of elementary excitations and its expression is accomplished
第三，近晶a相的序参量， ，都可用上述两种元激发来表示，给出了表达式。 - When liquid crystal ( lc ) is in smectic - a ( sa ) phase , its molecules disperse in layers ( sandwich ) and the molecular long axis tropism is in some order and the director is perpendicular to the layers
液晶近晶a相，分子质心按层状分布(有层状结构) ，分子长轴取向有序，指向矢垂直于层面。用三个序参量， ，描述。 - 5 , both melting point ( tm ) and isotropization temperature ( tj ) of all the three series compounds change regularly with the carbon numbers of the end alkoxy group increased . there is a gradual increase in smectic phase length and in the smectic - nemetic transition temperature . at the same time there is a gradual decrease in nemetic phase length
五，三个类型化合物16ia至16id 、 16ila至16lid 、 17ia至17id 、 17ila至17lid 、 18ia至18id和18ila至18lid的熔点和液晶态的清亮点均化合物分子中末端烷氧基增大逐渐降低；近晶相的温度范围和近晶相一向列相转变温度逐渐增大，而向列相的温度范围递减。 - Based on the understanding of netative poisson ratio mechanism and the characteristics of liquid crystalline polymers , the ability for the smectic liquid crystalline polymers possibly to bear the auxetic behavior was firstly proposed . at the same time the ideal molecular model was upbuilt and the calculation about the negative poisson ratio of smectic liquid crystalline polymers was theoretically carried out
经过对负泊松比产生机理和液晶高分子特征的理解，首次提出了近晶c相液晶高分子也具有产生npr效应的能力，建立了近晶c相液晶高分子产生负泊松比的分子模型，并且对其负泊松比进行了理论计算。
