Futuyma model, based on which the systematic grouping of niche overlap for all gamasid mites was completed by cluster analysis.

Futuyma 模型测定，并在此基础上用系统聚类分析进行生态位重叠群的划分。

The niche breadth could be used as an index for evaluating the host specificity of gamasid mites, whose similarity in population distribution was largely related to that of their hosts, as well as their taxonomic distance.

生态位宽度可以作为评价革螨宿主特异性的定量指标，革螨种群分布的相似性与其宿主的相似性程度有着很大的关系，并受其动物分类学远近的影响。

Objective To determine the niche breadth and overlap in eleven dominant species of gamasid mites parasitic on 39 species of small?mammal hosts around Biluoxueshan Mountain in Weixi, Yunnan.

目的 应用现代生态学中生态位的理论和方法，对云南省维西县碧罗雪山周边地带11种医学革螨在39种小兽宿主资源上的生态位宽度和生态位重叠进行研究。

YTY paper reinforcement of the recently developed a new water soluble polymer material, it is a high molecular weight polymer compound ionictype, mechanim, numberrepresentationof exesting non－ionic, and numberrepresentationof anions and cations, so this in paper-making process, you can and pulp fiber molecules multi-spots adsorption, which increases the fine celluiose filler and retention; at the same time it can also promote hydrogen between cellulose, and gives the paper jiantiao dry strength significantly increase, because the reinforcement of the unique structure, so it can be used with other paper cocatalyst compouding, a broad pH range as a reinforcement of the paper is available at wood pulp and wood pulp-straw gamasid mixed pulp and paper pulp etc.

YTY纸张补强剂系近期研制成功的新型水溶性高分子材料，它是一种高分子量复合离子型的高聚物，在其分子结构中，既有非离子基团，还有阴离子、阳离子基团，因此这在造纸过程中，可以与纸浆中的纤维分子形成多点吸附，从而提高填料与细纤维素的留着率；同时它还可促进纤维素分子之间的氢健作用，使纸张干强度明显提高，由于该补强剂分子的独特结构，因此它可与其它造纸助剂复配使用，能在较宽广的pH范围内，作为纸张补强剂，可以在木浆、木浆——草浆混合浆、革浆等多种纸浆中使用。

Non-parametric Mann-Whitney U -test showed that there was no significant difference between male and female hosts on the species richness and abundance of total ectoparasites, chigger mites, sucking lice, fleas or gamasid mites.

U 检验表明，体表寄生虫、恙螨、吸虱、蚤类和革螨的数量和物种数在雌雄宿主体表间的差异无统计学意义。
