Methods:Wild rodents were captured by snap-traps in three different ecological habitats in the region from June 1998 to May 1999.7 species of rodents,568 individuals were examined for ectoparasites,16 species of flea,3 species of tick,22 species of gamasid mite,and 7 species of chigger mite collected.

1998年6月至1999年5月在该地区的3类生境按常规方法共捕获鼠类7种568只，采集体外寄生虫48种3859只，其中蚤类16种582只，蜱类3种416只，革螨22种1081只，恙螨7种1780只。

Spearman correlation analysis showed that the abundance and species of total ectoparasites, chigger mites, sucking lice, fleas or gamasid mites were not correlated with the body weight of hosts.

Spearman相关分析表明，体表寄生虫、恙螨、吸虱、蚤类和革螨的数量与宿主身体参数之间无相关性。

We not only focus on the continual development and innovation of the technical strength and form an excellent technical team, but also emphasize on developing chrome free tanning technology and push green consumption on chrome free hides.

公司经过十来年的努力，已形成一套优异的生产工艺，在技术上精益求精，不但重视自身技术力量的不断壮大和开发创新，形成了一支优秀的技术队伍，而且重视强强合作，与四川大学在"建立年产 20 万张高档无铬牛皮汽车革高技术生产线"上进行全面合作。

本文就此问题着重介绍了如何从铬鞣废液及铬鞣革屑中回收铬及皮胶原，并将其重新用于皮革工业。

The thesis focused on recycling of chrome leather wastes and transforming them into value-added products.

作为世界皮革加工中心，我国每年约产生70多万吨铬革渣，其主要成分为胶原蛋白和铬盐。

Chrome-tanning process is still very important in leather industry for its special tanning properties.This process can produce some chrome effluent and chrome-tanned leather scraps,the reject of which not only can contaminate the environment but also can cause great economic losses.

铬鞣因其优异的鞣制性能，在制革工业中仍占据着重要地位，但由铬鞣产生的各种污染如铬鞣废液、铬鞣革屑等对环境具有极大危害，这些废液及材料的直接排放和丢弃，还会造成很大的经济损失。

The drying process of chrome liquor was studied. The structure and property of chrome complex reducing by alcohol were analysed and tokened by many present well-rounded separation and analysis methods such as IR, UV-Vis Spectrum, IEC and pH potentiometry. Application tests of chrome tanning agents were conducted and tanning methods of tanning at high pH were studied. A systematic study was conducted on high alkalinity chrome tanning agents application in leather making process and possibility of clean chrome tanning was discussed.

本文系统地研究了多种小分子醇与重铬酸盐之间的氧化-还原反应，对反应过程进行了认真的剖析；对铬鞣液的干燥过程进行了研究；用红外光谱法、紫外及可见分光光度法、离子色谱法以及pH电位滴定法等多种比较成熟的现代分离分析方法相结合，对醇还原铬配合物的结构与性能进行了分析与表征；对铬鞣剂的鞣革性能进行了应用实验，研究了醇铬鞣剂在高pH值下的鞣制方法，并就高碱度铬鞣剂在制革过程中的应用进行了系统研究，探讨了用其实施清洁化铬鞣的可能性。
