OBJECTIVE: To introduce the sorts of biomedical fibers, collagenous fibers, chitin fibers polyactic acid fibers, etc., and their preparation,properties and application respectively, and suggest China to pay attention to the research and development of biomedical fiber.

目的：介绍生物医学纤维的种类及甲壳素纤维、骨胶原纤维、聚乳酸纤维等主要生物医学纤维的制备技术、性能和用途，并建议国内应重视生物医学纤维的研究与开发。

The hydrolysis of chitin under concentrated alkali conditions would produce double anion because of conjugative effect and steric effect (producing primary amine which had positive ion properties and linear chain macromolecular structure and which has good flocculability and clarification performance).

因共轭效应和空间效应，甲壳质在浓碱条件下水解，能形成双负离子，形成具阳离子性质的伯胺和具有直链高分子结构，具有优良的絮凝性能和澄清作用。

Chitooligosaccharides was obtained from crustaceous materials, such as shrimp and crab by deacetylation and degradation, and it had a wide range of applications in medicine.

壳寡糖是由虾蟹壳等甲壳类物质通过脱乙酰基与降解而得到的寡糖，它在医药领域有广泛的应用。

objective:with the local lobster shell as the raw material,we inquire into the abstraction and preparation of chitin and chitosan to develop a new raw material resources for chitosan.methods:use methods such as take off protein,calcium,colour,deacetylate and purification to prepare chitosan to study deacetylate degree,molecular weight and other characters of chitosan,then compare with infrared spectrum of bio-chemical chitosan on market.results:the chitin and chitosan obtained from lobster shell are 14.8% and 8.9%, respectively.

目的：以地产龙虾壳为原料，探讨其甲壳素的提取和壳聚糖的制备方法，以开发壳聚糖制备的新原料资源。方法：用脱蛋白、除钙、脱色、脱乙酰基、纯化等方法制备壳聚糖，研究其壳聚糖的脱乙酰度、分子量等性质，并与市售生化级壳聚糖的红外光谱进行比较。

Snapping shrimps belonging to Decapoda are also highly diversitied, forming a large fauna in the world. Gobiids and snapping shrimps share same habitats to perform an intimately symbiotic relationships between them.

貌窸卫是海水鱼中最大的一科，歧异度非常高，是底栖型鱼类的主要组成部份；而枪虾也是一种歧异度很高的甲壳十足类，在全球珊瑚礁海域动物相中的数量占有相当大的比例。

Its test result, after using agent of sewage disposal of biology of carapace god ocean and technology of flood body rehabilitate, build good oxygen biology to stabilize a bed, processing sewage effect is apparent, expression is: Black smelly sewage is rapid decolour, deodorization, become clear, insipidity, the COD after handling two days by 333 drop 76, achieve view and admire water and the water quality demand that breed water, can develop aquatic substance. A green alga, red snapper grows to feed after 4 days wait for primary live thing, breed the water biology such as water hyacinth to be able to put in a suitable place to breed view and admire a fish.

其试验结果，运用甲壳神海洋生物污水处理(通过物化方法去除水中一些物质的过程)剂和大水体修复技术后，建立好氧生物稳定床，处理污水效果明显，表现为：黑臭的污水迅速脱色、脱臭，变得澄清、无味，处理两天后COD由333下降到76，达到观赏水和养殖水的水质要求，可培养水生物。4天后长出绿藻、红鱼食等初级生物，养殖水葫芦等水生物并可放养观赏鱼。

Tai zhou Fengrun , now is one of the biggest manufactures specialized in chitin derivant in China .
