  1. Studies on the liquid crystalline characters and phase transition behaviors of a poly ester imide copolymer

    聚酯酰亞胺共聚物的液晶特性和相轉變研究
  2. Abstract : methanesulfonic acid method was used to prepare five acylated chitins. except heptanoyl chitin, four of them, i. e. acetyl chitin, propionyl chitin, butyryl chitin and hexanoyl chitin, had high degree of substitution ( from 1. 5 to 2. 0 ) and exhibited lyotropic liquid crystalline behavior and cholesteric phase. as the length of the side chain increased the critical concentration ( w / w ) somewhat increased from 0. 21 to 0. 26 because the chain rigidity dropped. the critical concentration values of all the four derivatives were much higher than that of chitin ( 0. 12 ) due to the decrease of intramolecular hydrogen bonds. the four acylated chitin can form typical banded texture after being sheared. there minimum concentrations to form banded texture of them were evidently different, varied from 0. 25 ( for acetyl chitin ) to 0. 37 ( for hexanoyl chitin ). these results further indicated that liquid crystallinity decreased while the length of flexible side substituents increased

    文摘:四種羧酰化甲殼素即乙酰化、丙酰化、丁酰化和己酰化甲殼素在二氯乙酸溶液中均呈現膽甾型溶致液晶相.臨界濃度隨側基長度增加而略有增加，衍生物的臨界濃度明顯都比原甲殼素高許多，這些規律都可以用鏈剛性的變化來解釋.四種羧酰化甲殼素在剪切時均能形成條帶織構，而且能形成條帶織構的最低濃度有明顯差別，隨側基長度增加而提高，進一步表明側基較長，液晶性減少
  3. Thus while the upper surface of an oceanic plate is a crystalline solid, the underside exhibits a gradual phase change, from solid to plastic to viscous liquid as the temperatures and pressures increase with depth

    因此雖然一個洋殼的上部是晶體，下面卻顯示了逐步的變化，即當溫度和壓力隨深度增加時，便從固體到可塑體再到粘滯的液體。
  4. Side chain polyurethanes with azo group are characterized and confirmed by ftir, uv - vis, dsc, vpo, z - scan, polarize microscope. the results show that the end - group and the flexibility of main chain affects the growing up of liquid crystalline phase greatly. because the determinable way of detection is defective, it was not founded the liquid crystalline behavior obviously contributes to the non1inear optical thection

    最後，在分析討論實驗結果的基礎上，指出側鏈型聚氨酯液晶中側鏈介晶基元的末端基團及主鏈的柔性對其液晶態的形成有重要影響；由於檢測手段的不齊備，未能觀察到熔致型聚氨酯液晶的液晶行為對其非線性光學效應的貢獻作用。
  5. It is concluded that optimum calcined temperature is 900 with x < 0. 06 and 950 with x 0. 06. liquid phase is indispensable in the sinter procession. it contributes to the growth of the crystalline grain and the density

    研究表明：當x 0 . 06時，適宜的預合成溫度應為900 ，當x 0 . 06時，適宜的預合成溫度應為950 ；樣品的燒結必須有液相的存在，適量的液相有助於晶粒的生長和材料的緻密化，但液相過多將降低壓電性能。
  6. A change of phase, however, is a more fundamental change of physical form, as from a liquid to a vapor, or a change from one crystalline form to another

    然而，相位的變化是指物理形態的更為基本的變化，如從液體變為氣體，或從一種晶體變為另一種晶體。
  7. It also has stronger hydrogen bond which can result in partly physical crosslinkage in polymers, which can fasten orienting of chromophore. all these benefit to obtain high nlo coefficient. in chapter one, some basic conceptions about lc and the advance in lcpu are described, especially the synthesis methods on lcpu and the influence factors of lcpu formation liquid crystalline phase

    聚氨酯液晶是分子排列具有一定取向的聚合物材料，可為非線性光學聚氨酯提供一種較好的非對稱取向的介質環境，聚氨酯中還存在較強的氫鍵作用，使得聚合物材料有部分物理交聯，能固定發色團的取向，這些因素有利於獲得較大的非線性光學效應。
