	4.	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:四种羧酰化甲壳素即乙酰化、丙酰化、丁酰化和己酰化甲壳素在二氯乙酸溶液中均呈现胆甾型溶致液晶相.临界浓度随侧基长度增加而略有增加，衍生物的临界浓度明显都比原甲壳素高许多，这些规律都可以用链刚性的变化来解释.四种羧酰化甲壳素在剪切时均能形成条带织构，而且能形成条带织构的最低浓度有明显差别，随侧基长度增加而提高，进一步表明侧基较长，液晶性减少
	5.	The results show that , ( 1 ) under observable contracts , suppliers ' horizontal merger will have adverse impact on customers , while the impact of retailers ' horizontal merger on customers depends on the degree of product substitution : if the degree of substitution is high , it will have favorable effect on customers , otherwise , it will have adverse impact on customers ; ( 2 ) under unobservable contracts , suppliers ' horizontal merger generally will have unfavorable impacts on retailers and customers , while the effect of retailers ' horizontal merger on customers depends on the degree of product substitution : if the degree of substitution is high , it will have favorable effect on customers , otherwise , it will have adverse impact on customers 结果表明： ( 1 )当合约可观察时，供应商横向兼并对消费者产生不利影响，而零售商横向兼并对消费者产生的影响取决于产品替代性程度大小，若产品替代性程度较高，则将产生有利影响，反之将产生不利影响； ( 2 )当合约不可观察时，供应商横向兼并一般将对零售商与消费者产生不利影响，而零售商横向兼并对消费者产生的影响取决于产品替代性程度大小，若产品替代性程度较大，则兼并将对消费者产生有利影响，否则将对消费者产生不利影响。
	6.	Abstract : highly substituted cationic starch was prepared by microwave radiation in dry process . in this preparation , starting materials mixed with high speed stirres , potassium hydroxide used as catalyst and discontinuous heated by microwave radiation at temperature 60 85 to give 0 35 0 50 degree of substitution cationic starch the conversion of cationic reagent reached 95 the product is soluble in water it is pasted when it meets water 文摘:微波干法制取高取代度的阳离子淀粉，用高速搅拌机混合物料，氢氧化钾做催化剂，间歇式微波介电加热温度不超过85 ，阳离子试剂的转化率可达95 ，产品取代度0 35 0 50 ，常温下遇水糊化，在水中有较好的溶解性。
