发现低分子量的岩藻聚糖硫酸醋对LDL有很好的抑制作用，活性明显高于大分子的组份，而且硫酸根含t越高，抗氧化效果越好。

Result: All the basic additives investigated in the experiment showed good potential to relieve the level of acid collection in the course of PLGA degradation. Among those, the relieving ability of NaHCO3 was in the top, basic amino acid in the moderate, while Algin and chitosan ranked lower. 5% addition of Lysine produced a best outcome.

结果：各种碱性添加剂都有一定的缓解酸度的能力， NaHCO3的缓解能力最强，海藻酸钠和壳聚糖的缓解能力较低，而碱性氨基酸的缓解能力适中；赖氨酸为5%时的添加量时能够得到较佳的综合调节缓解效果。

The hydrolysis of birchwood xylan yielded mainly xylobiose and xylotriose, no xylose was detected by TLC. Therefore, XynA may be suitable for production of xylooligosaccharides.

XynA水解桦木木聚糖的主要产物为木二糖和木三糖，无木糖生成，说明它适合应用于低聚木糖的生产。

Manna gets together carbohydrase ferments the process controls systematic wiring parameter of complex, influence rate of much, automation is low, because this designs,be based on CAN spot bus line ferment the process controls a system.

梗概： β-甘露聚糖酶发酵过程控制系统布线复杂、影响参数多、自动化程度低，因此设计一套基于CAN现场总线的发酵过程控制系统。

Chitosan, derived from the deacetylation of chitin, is rich in nature.

低分子量的水溶性壳聚糖具有独特的生理活性和药用价值。

Results The concentration-time curve of glucan was hyperbola and its time-reaction curve had low reaction rate.

结果 葡聚糖的浓度时间曲线双曲线，时间反应曲线显示反应速率较低。

The induction of xylanase activity is dependent on inducer concentration and is not fully repressible by glucose and starch.

木糖在低浓度下具有诱导WL-11木聚糖酶生物合成的作用，但高浓度木糖则表现出一定的代谢终产物抑制效应。

This paper deals with different ways to depolymerize the chitosan into water soluble low molecular weight polymer.Molecular weight of water soluble low molecular weight chitosan was determinated by GFC.

探讨并比较了壳聚糖解聚成水溶性低聚物的不同途径，用GFC方法测定了水溶性低聚物的相对分子质量，证实选用NaNO2作解聚剂解聚效果良好。

The domestic "Su 4" and "ken 7" barleys activity change of main hydrolase in the process of barleys malting were investigated, and the study comparing it with Gairdner and Schooner barleys activity change indicate that "Su 4" and "ken 7" barleys amylase, phytase, and cellulase is with high activity, and its protease and xylanase with low activtiy,"Su 4" barleys peroxidase with low activitiy, and its polyphenol oxidase with high activity, but it is the opposite for "ken 7".

研究了国产大麦苏4和垦7在发芽过程中主要水解酶活力变化，同时与进口大麦Gairdner和Schooner比较发现：苏4和垦7的淀粉酶、植酸酶、纤维素酶活力较高；蛋白酶和木聚糖酶活力较低；苏4过氧化物酶活力较低，多酚氧化酶活力较高，垦7则相反。

Because supercritical and near-critical water have special solubility, high ion product, low surface tension and high diffusion coefficient, chitosan can be degraded into soluble chitooligosaccharide rapidly.

超临界水具有特殊的溶解度、很高的离子积、较低的粘度、较低的表面张力和较高的扩散系数，使得壳聚糖在超临界水中能够快速降解成可水溶的壳寡糖。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
