smectic phase 中文意思是什麼

smectic phase 解釋
層滑型介晶相
  • smectic : adj. 1. 【化學】碟狀液晶分子的,近晶的。2. 凈化的。
  • phase : n 1 形勢,局面,狀態;階級。2 方面,側面。3 【天文學】(月等的)變相,盈虧;【物、天】相,周相,...
  1. 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相的序參量, ,都可用上述兩種元激發來表示,給出了表達式。
  2. 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,分子質心按層狀分佈(有層狀結構) ,分子長軸取向有序,指向矢垂直於層面。用三個序參量, ,描述。
  3. 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

    五,三個類型化合物16ia至16id 、 16ila至16lid 、 17ia至17id 、 17ila至17lid 、 18ia至18id和18ila至18lid的熔點和液晶態的清亮點均化合物分子中末端烷氧基增大逐漸降低;近晶相的溫度范圍和近晶相一向列相轉變溫度逐漸增大,而向列相的溫度范圍遞減。
  4. 2, upon heating to their respective melting temperature, all the compounds above went to liquid crystal phase. the typical chiral smectic c phase lined texture and finger print texture, smectic fan texture and broken fan shaped texture, nematic schlieren texture schlieren texture and ball grandle texture, paramorphosis texture can be observed

    實驗結果表明:一,化合物2 、 4 、 16 、 17和18均具有熱致液晶性;二,以上化合物加熱至各自的熔點以上都能形成液晶態,在液晶態可以觀察到新的席夫堿型液晶冠醚的合成與表徵手性近晶c相的層線織構和指紋織構。
