  10. 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
  11. Collisonal quantum interference ( cqi ) was observed in the intramolecular rotational energy transfer in the experiment of the static cell, and the integral interference angles were measured. to observe more precise information, the experiment in the molecular beam should be taken, from which the differential interference angle can be obtained precisely. in this paper, the theoretical model of cqi is described in an atom - diatom system in the condition of the molecular beam, based on the first - born approximation of time dependent perturbation theory, taking into accounts the anisotropic lennard - jones interaction potentials. the method of observing and measuring correctly the differential interference angle is presented. the changing tendencies of the differential interference angle with the impact parameter, velocity, and et al. are discussed

  12. We have more interest in benzofuroxans with amino and nitro substituents because the effect of pushing electron of amino group increases the bond energy of c - no2, and there are strong intramolecular and intermolecular hydrogen bonds between amino and nitro group. these hydrogen contacts can make the molecular structure more stability. so aminonitrobenzodifuroxan may have good heat resistance and low impact sensitivity

There are 4 cysteins in the protein hbfgf, cysteins 78 and 96 are localized on the surface of hbfgf, whereas cystein 34 is completely buried and cystein 101 is partly buried within the folded peptide chain. so the cys78 and cys96 are especially prone to intramolecular disulphide - bond formation. we converted these two cysteins into serines

    同時對於155個氨基酸的hbfgf來說，其34 、 78 、 96和101位的四個半胱氨酸的巰基有形成二硫鍵的可能，是造成二聚體或多聚體的主要原因，其中cys34隱藏在分子內部， cys101部分包埋在分子中； cys78和cys96暴露在蛋白質的表面，很容易因cys78和cys96的游離巰基氧化，在不同的分子間形成錯誤的二硫鍵。
