1, These chitin fibres are embedded in matrix materials, making the wall material like a carbon fibre composite.

2, Chitin is a polymer of N - acetylglucosamine.

3, Chitin is an important reclaimable resource.

4, Chitin has a tight connection with human life.

5, The chitosan was prepared from chitin by deacetylating and the degree of deacetylation was 83%.

6, Chitosan is material from deacetylation of chitin, which from arthropod, coelenterate, annelids, protozoans, part of algae and fungi.

7, The structures, properties and application of chitin and chitosan wereand production pro cess there of presented.

8, Objective : To investigate the modification of chitin spray treatment of eczema of the auricle.

9, This paper reviews the application of chitin and its derivatives in medicine, including medical dressing, ophthalmic materials and pharmaceutical preparations.

10, Chitosamine generated via degradation of chitin is also used in synthesis of biochemical reagents and medicine intermediates.

11, Because of its unique molecular structure, chitin, along with its application and study, has become one of the points at issue on the study of polysaccharose, .

12, The use of chitin with inherent mildewproof features makes the paint un-deteriorated without added preservative and the paint film midewproof and environment protecting.

13, Objective: To investigate the biocompatibility of chitin as bone substitute material.
