Objective:To produce low-sugar and high-moisture preserved pachyrhizus; Methods:The relationship of moisture and water activity, numbers of bacterial and mildew were researched. Then water activity was reduced by chitosans with different viscosity-average molecular weights; Results:The number of mildew was a major microbial index of quality-maintaining duration of product. The lower viscosity-average molecular weights of chitosans was, the more water activity reduced; Conclusion:When 9 kD molecular weight,...
目的:为生产低糖、高水分含量番薯果脯;方法:研究果脯中水分含量与水分活度的关系及细菌总数和霉菌数在保温试验中的变化,并采用不同黏均分子量的壳聚糖降低果脯的水分活度;结果:果脯中霉菌数是影响产品保质期的主要微生物指标,壳聚糖的黏均分子量越低,降低水分活度的幅度越大;结论:通过添加0.5%、9kD黏均分子量的壳聚糖,产品水分含量为20%、总糖为26%时,番薯果脯常温放置保值期达到12个月。

Especially, it is found that there exists three types of relative permeability of water such as concave, convex to the water saturation ax and the reversed "S" pattern. The super-low permeability reservoir is sensitive to pressure, apparent with millipore undersaturation and water blocks. In this study, a new concept of irriducible undersaturation is brought up. And a new mode to describle the process of imbibition dynamics is used to reveal and confirm the mechanism of pinhole enveloping macropore as following: pendular ring of wetting phase gathers→it fills throat→it truncates nonwejting phase . The expression of pressure distribution and the equation of oil production are deduced under conditions of non-darcy linear seepage and non-linear seepage.
尤其发现水相相对渗透率曲线存在凹向、凸向含水饱和度轴及反S形三种形式;特低渗透储层的压力敏感性强,微孔隙的欠饱和及水锁效应显著,本文研究中提出欠束缚水饱和度的概念,引用一种描述渗吸动态即湿相液环聚集→充填喉道→截断非湿相的演化过程的新方法,更深刻地揭示和证明了&小孔包围大孔&机理;推导出了非达西线性渗流和非线性渗流条件下的压力分布表达式和油井产量方程。

Effects of quinhydrone, as urease inhibitor, on growth, root activities, nitrogen metabolism, photosynthetic character, yield as well as quality were studied under pot experiment with water spanich and plot experiment with B.chinensis Var.comrtzunis. The results were shown as follow: 1. Applying low and medium amount quinhydrone promoted the growth of water spanich and B.chinensis Va,communis, whereas high amount treatment had little effect on water spanich growth, and inhibited the growth of B.chinensis Var communis.

The water chamber takes the shape of tilting cube, in favor of uniform distribution of cooling water on tube plate surface. The tube bundle is divided into two groups of zygomorphy according to the bisection system and it has eight support clapboards. The siphonopore center of each clapboard increases a certain distance corresponding to that of two tube plates and the cooling tube takes the shape of arch. The two-way cooling water of bisection flows through the condenser in opposite direction so as to improve the distribution of heat load for tube bundle. Around the throat of condenser, the final stage low-pressure heater, air extraction tube, intake device of bypass exhaust and the like are deployed.
它的特点是:水室呈倾斜立方体形状,有利于冷却水流在管板面上均匀分布;由于采用对分制,管束相应地分为左、右对称的两组,并且管束设有八块支撑隔板,每块隔板的管孔中心相对于两端管板的管孔中心依次抬高一定的距离,以使冷却管呈拱形状;对分制的两路冷却水以相反方向流过凝汽器,从而改善管束的热负荷分布;在凝汽器喉部布置了末级低压加热器,抽汽管道及旁路排汽接受装置等。
