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
