The objective of this paper is to study the oscillatory and asymptotic properties of the general mixed type third order neutral difference equation of the form △（aαn△2（xn＋ bnxn-τ1＋ cnxn＋τ2））＋ qnx^a n＋1-σ＋ pnx^βn＋1＋=σ2 0,where {an}, {bn}, {cn}, {qn} and {pn} are positive real sequences, both α and β are ratios of odd positive integers, τ1, τ2, σ1 and σ2 are positive integers. We establish some sufficient conditions which ensure all solutions are either oscillatory or converge to zero.

本文采用密度泛函(DFT)方法研究了定向外电场(OEEF)对W_(6)C_(6)团簇几何结构、电子性质以及非线性光学响应(NLO)的影响.计算结果表明W_(6)C_(6)的结构在一定OEEF强度下可以保持稳定.OEEF可以增大W_(6)C_(6)团簇的电子亲和能(EA值),且在特定强度下,OEEF可以将W_(6)C_(6)团簇转变为超卤素.通过对EA值的非线性拟合可以实现对W_(6)C_(6)团簇的连续调制.进一步对不同外电场下W_(6)C_(6)团簇的最高占据分子轨道(HOMO)和最低未占据分子轨道(LUMO)能级进行分析,发现OEEF降低了W_(6)C_(6)团簇LUMO能级是其EA值增大的主因.此外,OEEF可以显著增大W_(6)C_(6)团簇的平均极化率和第一超极化率,尤其是第一超极化率,改变其非线性光学性质.

为探究预制西兰花加工过程中烫漂方式及冷冻速率对西兰花质构品质的影响,对经2种烫漂方式(热水烫漂、蒸汽烫漂)及3种冷冻温度(-20、-40、-80℃)处理的西兰花样品,利用低场核磁共振、理化特性分析方法测定不同处理组样品的水分分布、持水性、相对电导率和硬度,观察微观结构。结果表明:维持西兰花硬度的最佳工艺为蒸汽烫漂后进行-40℃冷冻,在此工艺条件下,与对照组相比,处理组西兰花水分分布中结合水峰面积占比(A21)增加最多、持水性最强,花序部分保留66.72%硬度、茎部分保留62.53%硬度,相对电导率增加至87.01%;通过扫描电子显微镜观察发现,经过该处理的西兰花保持了较好的细胞结构。本研究得到了有效维持解冻西兰花质构的工艺,并揭示了不同处理对西兰花水分分布及细胞膜完整性影响的机制,为实际生产过程保持冷冻预制西兰花品质提供了理论与技术支撑。
