线虫纲

Arthropoda, Class Crustacea, Subclass Copepoda are beyond the present scope. The parasitic helminth faunas of rabbit fish, cutless fish, spotted mackerel, horse mackerel, grey mullet, and cobia were investigated.

本研究之对象为台湾海鱼蠕虫类寄生虫，包括：扁形动物门之单殖吸虫纲，吸虫纲内之复殖吸虫亚纲和绦虫纲；俗称线虫或圆虫之圆形动物门；棘头虫动物门中之始新棘头虫纲等；但不包含属於外寄生性之节肢动物门甲壳纲中的桡足亚纲。

Through investigation, 26 kinds of soil animal were collected , which could be classified into 9 classes belonging to 4 phyla. The dominent group taxa of among them were Nematoda, Collembola and Acarina.

在土壤重金属污染8个样地中，共获取土壤动物26类，隶属于4门9纲，优势类群为弹尾类、螨类和线虫类，常见类群8类，稀有类群15类。

To make the classification of Helminthism of the livestock and poultry more convenient and short-cuting, the key system was set up by the programming language of Visual Basic. According to the morphologic characters of the orders, families and genuses of Cestoidea, Trematoda and Nematoda, a database was established. The correlative data can be searched easily and quickly.

为了使畜禽寄生蠕虫形态学分类更加方便、简捷，采用Visual Basic可视化的计算机编程语言，根据绦虫纲、吸虫纲、线虫纲和棘头虫纲的各目、科和属的虫体形态特征建立数据库，通过资料查询系统，可方便快捷的对相关资料进行查询。

The soil faunal specimens collected belonged to 4 phyla, 6 classes and 12 orders. Nematoda was the only dominant group of medium- and small-sized soil fauna, occupying 94.3% of the total, while Coleoptera and Hemiptera were the dominant groups of large-sized soil fauna, with the amount of 79.7%.

共获得土壤动物4门6纲12目，优势类群中小型土壤动物仅线虫目1类，占总捕获量的94.3%；大型土壤动物为鞘翅目和半翅目2类，占总捕获量的79.7%。

Any of several worms of the phylum Nematoda,having unsegmented,cylindrical bodies,often narrowing at each end,and including parasitic forms such as the hookworm and pinworm.

线虫线虫纲动物的任何一种小虫，身体不分节，呈柱状，两头稍尖，包括钩虫和蛲虫一样的寄生虫

Result In subalpine coniferous forest in western Sichuan, the Nematoda, Acarina and Collembola were the dominant groups of soil animal community and Diplopoda, Harpacticoida, Rotatoria, Enchytraeidae and Diptera were the frequent groups.

结果］川西亚高山针叶林土壤动物群落以线虫纲、蜱螨目、弹尾目为优势类群，以倍足纲、猛水蚤目、轮虫纲、线蚓科、双翅目幼虫等为常见类群。

It reported for the first time the change between niche breadth and niche overlap of the three kinds of parasite, which are Acanthocephala, Digenea and Capillaria in the digest tube of Monopterus albus , and the relation with the intensity of infection correlation.

摘 要：为探明寄生虫对黄鳝的危害，对黄鳝消化道内三大类寄生虫棘头虫门、复殖吸虫纲和毛细线虫属的生态位宽度和生态位重叠随季节的变化及其与寄生虫感染强度的关系进行了研究。

为了使畜禽寄生蠕虫形态学分类更加方便、简捷，采用Visual Basic可视化的计算机编程语言，根据绦虫纲、吸虫纲、线虫纲和棘头虫纲的各目、科和属的虫体形态特徵建立数据库，通过资料查询系统，可方便快捷的对相关资料进行查询。

Now, however, all children continue in "comprehensive" schools, and the eleven-plus determines which courses of study the child will follow.

然而现在，所有的孩子都要在综合学校继续学习，所以这次考试只是决定他们将要学习哪些课程。

Cultivatable land , and led to a general recognition that development must not be carried at the cost of agriculture .

城区的迅速扩大在很多情况下侵占了宝贵的可耕地，使人们普遍认识到发展不能以牺牲农业为代价。
