Hypotrichids ciliate macronucleus chromosome was named "genesize chromosome", which carrying the gene coding sequence flankedby short non-translated regions and bounded by telomeres (C_4)_4(A_4)_3.Macronucleus chromosome is furthest simple chromosome ineukaryotic cell.

下毛类纤毛虫的大核染色体被称为"基因大小染色体(gene-size chromosome)"，其含有一个基因编码序列，5′和3′端各有一段基因表达调控序列以及端粒序列(C_4)_4(A_4)_3，是真核生物中结构最简约染色体。

A preliminary investigation of composition and dominant species of ciliata in Yanghe River was conducted, and totally 46 species were detected by physicochemical monitoring of the water quality.

对洋河的纤毛虫的种类组成、优势种进行了初步调查，同时对水质进行理化监测，共鉴定出纤毛虫46种。

Lastly, based on analysis on phylogentic relationships among 39 ciliates combined with their main morphologic characters, some conclusion were drawn: 1 the monophyly of the peritrichs was strongly supported, and its subclass rank in the class Oligohymenophorea is reasonable; 2 the genus Epistylis might not be monophyletic, and the peristomial area, especially the peristomial lip, might be an important phylogenetic character within the genus Epistylis; 3 the taxonomic rank of the genus Carchesium and the genus Campanella were suggested to be adjusted; 4 Opisthonecta probably diverged from peritrichs with stalks; 5 the phylogenetic tree of peritrichs was reconstructed based on the molecular information inferred from SSrRNA gene sequences and the morphology.

测定了6科8属13种缘毛类纤毛虫的SSrDNA序列，将构建的最大简约树和邻接树与形态学相结合，分析得出：1）缘毛类纤毛虫是单系的，其分类地位是隶属于纤毛门寡膜纲缘毛亚纲：2）指出累枝虫属可能不是单系的，口围区是累枝虫属中重要的系统发育特征；3）建议调整独缩虫和聚钟虫属的分类地位；4）得出后游虫可能是由有柄缘毛类进化而来的类群；5）基于缘毛类反口区结构和SSrRNA基因序列提供的信息重建了缘毛类纤毛虫的系统发育树。

These offered new basic informations and new views for classification and phylogenesis of hypotrichous ciliates and continually exploring the determinant factor of the formation of the cuticle ciliary pattern of ciliates.

这些为进一步探索纤毛虫皮层纤毛模式的形成和决定，为下毛类纤毛虫的分类和系统演化及细胞学等的研究提供新的基础资料和见解。

Five splice experiments in Stylonychia mytilus have been done which revealed the effect of positional value theory and the pre-existing ciliary structure in the formation of ciliary pattern of mirror-image doublets.And the result indicated that the morphogenesis of the cuticle ciliary pattern of ciliate was controlled by multiple factors.

通过五项骈接实验，揭示了位置值理论和纤毛虫的预存结构等在棘尾虫骈体纤毛模式形成中的影响和作用，表明纤毛虫皮层纤毛模式的形成和决定是受多重因素的控制。

The composition and dominant species of ciliates in Baiyangdian lake was investigated,there are 48 species of ciliates by physicochemical test.

对白洋淀纤毛虫的种类组成、优势种进行了初步调查，同时对水质进行理化监测，共鉴定出纤毛虫48种。

Glass slides were used as artificial substrates for collecting ciliates from a closed intensive shrimp-farming pond near Qingdao, China.

为了解周丛纤毛虫在特定海水养殖环境中的功能与地位，作者以青岛近郊一封闭式海水对虾养殖池为采集地，采用人工基质法对周丛类纤毛虫的群落结构进行了为期140d的调查，同时开展了环境理化因子的采集和分析。

The ciliates were always ideal materials in the studies of the structure and function of cytoskeleton and its cell control and adjustment, for they have many kinds of cytoskeletons with complexity and they could be easily cultured and handled.

由于原生动物纤毛虫具有多种复杂的细胞骨架结构，加之其材料培养和处理的优点，一直被作为研究细胞骨架结构与功能及其细胞调控的理想材料。20世纪80年代初，许多学者应用蛋白银染色方法和超微结构方法，显示了纤毛虫细胞皮层中以纤毛基体作为主成分的骨架结构，探讨了纤毛虫皮层纤毛器的形态、形态发生及其结构形成机理，在国内外原生动物细胞学领域成为主流。20世纪90年代起，先后应用非离子去垢剂处理和扫描电镜相结合的方法、稳定保存微管结构的透射电镜术，微管蛋白的抗体标记及其免疫荧光技术及相关的生化与分子生物学等方法显示纤毛虫的微管胞器及其微管蛋白组分，探索微管胞器的形态、功能及其微管装配机理，积累了较多的资料，取得了重要的进展。
