The mice inoculated with Coxiella burnetii intrana- sally developed interstitial pneumonia,while the primary pathological changes of mice inoculated intraperitoneally are granulomas in spleen and liver.2.The pathological changes became more severe followed the dosage increasing.3.Coxiella burnetii can be detected in spleen and liver at day 2 after inoculation.the lesion became more and more serious from day 2 to day 12.The characteristic changes were observed at day 7,and recovered at day 14. 4.The reticuloendothelial system are main target of Coxiella burnetii.The pathogen was detected in cytoplasm of monocyte -macrophages of spleen, liver, lung, and endothelioid cells of blood vessel. 5. Coxiella burnetii can be found in macrophages lysosomes by electron microscopy. Most of them are round or rod, and polymorphic shape can also be observed in different size.

结果：1、通过不同感染途径的实验证实，滴鼻感染的小鼠主要表现为间质性肺炎，而腹腔注射感染小鼠则以脾脏、肝脏肉芽肿为主要病变。2、通过不同剂量的感染实验发现，随着感染Q热立克次体剂量的加大，动物病变愈加严重。3、通过感染后不同时间的动态病理学观察发现，在腹腔注射后第2d的脾和肝脏即可发现病原体，主要脏器的病理变化从第2d到第12d逐渐加重，第7d动物的病变最典型，至感染后14d动物的受损器官已开始出现修复性变化。4、 Q热立克次体主要侵害机体的网状内皮系统，在感染小鼠的肝、脾、肺和外周血管单核巨噬细胞以及血管内皮细胞胞浆中查见病原体。5、透射电镜观察可见Q热立克次体主要位于巨噬细胞吞噬溶酶体内，呈多形性，多见圆形和杆状，大小不一。

One of the most decisive pieces of polar bear information is that these animals are an imperiled species , and a combination of education about bears combined with a national conservation policy is needed to ensure that these magnificent ambassadors of arctic wildlife continue to survive , notwithstanding the continuing trespass into their habitat and the endless search for resources , which fouls and despoils the pristine wilderness which these animals call home .

其中的最具有决定性的件北极熊的消息是，这些动物是一种危害的物种，并结合教育负有结合国家自然保育政策需要，以确保这些宏伟大使北极野生动物保护继续生存下去，尽管继续侵入到他们的栖息地和无休止的搜索资源，犯规和 despoils 原始的荒野，这些动物的家里打电话。

First, in view of a question our supposition newborn babys quantity is , then through to various ages stages survival percentage , the animal quantity which as well as this animals overall quantity analysis moves away establishes this community the dynamic change model , uses in this community near two years various ages stage individual quantity distribution which moves away, with the C language programming computation, extrapolates the current this animals age structure.

首先，针对问题一我们假设新生幼仔的数量为，然后通过对各年龄阶段的存活率、被运走的动物数量以及该动物的总体数量的分析来建立该群落的动态变化模型，利用该群落近两年内被运走的各年龄阶段的个体数量分布，用C语言编程计算，推测出当前该动物的年龄结构。

The journal publishes original and significant contributions on the systematics and phylogeny of invertebrates worldwide, including papers on defined taxonomic groups and on the phylogeny, biogeography and/or other aspects of biodiversity and general biology of the group; contributions on the systematics of selected species; short, general papers, pertinent to invertebrate systematic biology on methodology, theoretical systematics, cladistics, phylogeny, molecular biology and biogeography; reviews of general invertebrate systematics, containing innovative data or overviews of current theories.

杂志刊载世界范围内的无脊椎动物的系统分类学和系统发育的原始和重要投稿，包括关于精确分类种群和种群生物多样性与普通生物学的系统发育，生物地理和/或其它方面的论文；关于选择物种系统分类学的投稿；有关无脊椎动物系统生物学的方法学，理论系统分类学，遗传分类学，系统发育，分子生物学和生物地理的短概括性论文；无脊椎动物普通系统分类学的评论，包括新数据或当前理论的观点。

Often I have visited the New York Museum of Natural History to touch with my hands many of the objects there exhibited, but I have longed to see with my eyes the condensed history of the earth and its inhabitants displayed there-animals and the race of men pictured in their native environment, gigantic carcasses of dinosaurs and mastodons which roamed the earth long before man appeared, with his tiny stature and powerful brain, to conquer the animal kingdom, realistic presentations of the processes of evolution in animals, in man, and in the implements which man has used to fashion for himself a secure home on this planet, and a thousand and one other aspects of natural history.

我经常到纽约自然历史博物馆去，用双手无数次地抚摸过那里陈列的展品，我多么渴望能用自己的眼睛看一看这浓缩的地球的历史，以及陈列在那里的地球上的居民--各种动物和以他们生活的天然环境为背景描绘的不同肤色的人种；以及早在人类出现以前就漫游在地球上的恐龙和柱牙象的巨大骨架，当时的人类靠自己矮小的身躯和发达的大脑征服了动物的王国；还有表现动物和人类进化过程的逼真画面，和人类用来为自己在这个星球上建造安全居处的工具，以及另外许许多多自然历史的其他方面的事物。

The results showed that the free-living marine nematodes were the dominant group the percentage of which in the total number of meiofauna ranging betwean 76.1%~96.3%. The abundance of meiofauna in old mangrove district was the least and in bare beach where waste water flows was the most. There were a total of 37 putative species in the samples. The total number of recorded species was the lowest in the new mangrove district, and highest in the old mangrove district. The species diversity indexes, species evenness indexes and richness indexes in old mangrove district were all higher than those in new mangrove district. The dominant species and feeding types were different in three types of habitats.

结果表明：海洋线虫是凤林红树林中小型底栖动物中的绝对优势类群，占到小型底栖动物的76.1%~96.3%；从丰度来看，旧区白骨壤林中小型底栖动物的数量较少，有污水流过的光滩数量较大；4个断面共鉴定出海洋线虫37种，其中新区秋茄林中的生物多样性指数较低，旧区白骨壤林中群落具有较高的物种多样性；从出现的物种来看，新区秋茄林、旧区白骨壤林和光滩上出现的优势种和摄食功能群的类型各不相同。

Diversity of soil surface, stone gully and stone pit is 1.199, 1.592 and 1.962; evenness index of soil surface, stone gully and stone pit is 0.616, 0.989 and 1.095; dominance of soil surface, stone gully and stone pit is 0.545, 0.353 and 0.245 in soil macrofauna community structure.

土面生境土壤动物的多样性指数为1.199，石沟的为1.592，石槽的为1.962；土面生境土壤动物的均匀性指数为0.616，石沟的为0.989，石槽的为1.095；土面生境土壤动物的优势度为0.545，石沟的为0.353，石槽为0.245。
