Abstract: 采用湿热法制得了锥栗重结晶淀粉,研究了贮藏条件对其理化特性的影响。结果表明:在4 ℃贮藏时,对重结晶淀粉体外消化动力学参数的影响很显著,能形成更多的抗性淀粉,第14天平均聚合度达到最大,晶型从贮藏0 d的A型,依次转变为第3 d、7 d的V型,第14 d、21 d的B型,相对结晶度变化非常显著;在25 ℃贮藏时对体外消化动力学参数的影响也较大,能形成更多的快速消化淀粉,第3天平均聚合度达到最大,晶型保持A型,相对结晶度变化不明显,仅出现低温熔融区,与4 ℃贮藏时相比,其熔融焓降低较多、熔融峰温度差降低更显著;在4/25 ℃贮藏时,对体外消化动力学参数的影响也很显著,能形成更多的缓慢消化淀粉,前7 d内平均聚合度增加较快,晶型从贮藏0 d的A型依次转变为第3 d的V型、第7 d和第14 d的B型、第21 d的V型,相对结晶度变化较快,高温熔融区的峰值温度和终止温度较之4 ℃贮藏时降低较多。
Starch from Castanea henryi was recrystallized by heat-moisture treatment; in addition, the effect of different storage conditions on the physical and chemical properties of recrystallized starch was studied. Storage at 4 ℃ was observed to exert a significant influence on the in vitro digestion kinetic parameters of recrystallized starch; in addition, storage at this temperature resulted in the formation of starch with greater resistance, with the average degree of polymerization reaching the maximum limit on the 14th day. The type of crystal showed a gradual change from type A (on day 0) to type V on the 3rd and 7th day, and type B on the 14th and 21st day, with significant alterations in the relative crystallinity. Storage at 25 ℃ also had a substantial effect on the in vitro digestion kinetic parameters, resulting in the formation of starch that could be digested faster. The maximum average degree of polymerization was achieved on day 3; the crystal type from day 0 (type A) was retained over time, and the changes in relative crystallinity were not obvious, excluding the appearance of a low-temperature melting zone. The melting enthalpy of crystallized starch stored at 25 ℃ was substantially reduced compared to that stored at 4 ℃; in addition, the reduction in melting peak temperature was observed to be more prominent. Storage at 4/25 ℃ also had a significant effect on the in vitro digestion kinetic parameters, resulting in the formation of starch that was slowly digested. This resulted in a relatively rapid increase in the average degree of polymerization up to the 7th day. The crystal type was altered from type A on day 0 to type V on the day 3, type B on the 7th and 14th days, and type V on the 21st day. Rapid changes in relative crystallinity were observed. In addition, the peak and conclusion temperatures of the high temperature melting zone decreased by large amounts compared to the 4 ℃ storage condition.

In this paper, we study the synchronization of memristive neural networks with time-varying delays. Using the framework of Filippov solution, the differential inclusion theory and the adaptive control technique in combination with a novel Lyapunov function, we obtain a class of sufficient adaptive synchronization criteria in terms of memristive neural networks. Finally, the validity of the synchronization condition is verified by means of simulation experiments

Abstract:
研究郁金香生长发育与温度的关系,为郁金香的设计和配置提供依据。本实验以15个郁金香品种作为试验材料,主要研究露地栽培时郁金香生长发育与温度变化强度、有效积温的关系。试验结果表明:郁金香植物配置应根据品种的生物学特性和种植方法进行配球。低矮、窄冠幅品种应适当增加种植密度,株型高、冠幅大品种应适当降低用球数量,适度的种植密度能降低种植成本。供试郁金香品种发育阈温度6℃~7℃;以萌芽–开花积温为依据,栽培时通过调控积温,使不同类群的郁金香品种花期保持一致。
Studying the relation between temperature and growth provides the basis for designing. Taking 15 species as the test material, this paper is mainly to research the relationship between growth and intensity of changes in temperature and effective accumulated temperature of the relationship in land. The results show that designing should be carried out according to the biological characteristics and planting way. Low varieties should be appropriate to increase the planting density and high varieties should be appropriate to reduce the ball number. Appropriate planting density can reduce the cost of planting. The developmental threshold temperatures of different tulips are among 6?C - 7?C; based on sprout-blossom accumulated temperature, through controlling the effective accumulated temperature, the tulip cultivars will flower at the same time.
