Effects of different medias on the population growth of three marine ciliates, Euplotes vannus Müller, 1786, Uronema marinum Dujardin, 1841 and Paranophrys magna Borror, 1972, were investigated using experimental ecological method in beef extract and rice grain medium. Analysis of data revealed that the natural growth rate and the population densities of E.
为揭示不同培养液对纤毛虫种群增长的影响，本工作利用实验生态学方法对海水养殖水体中3种常见的纤毛虫原生动物，扇形游仆虫（Euplotes vannus Müller， 1786）、海洋尾丝虫（Uronema marinum Dujardin， 1841）和巨大拟阿脑虫（Paranophrys magna Borror， 1972）在两种培养液中的种群生长过程进行了探讨。

In this paper, the research object is the XM18 spherical generator, in order to improve the dynamic behavior of the machine tool, the following aspects have been studied in this thesis: Firstly, based on the elasticity theory and finite element analysis theory, the finite element models of the lathe bed, dovetail, dovetail shelf, headstock, fanlike plank and millhead shelf, which were the main parts of the spherical generator, were built up using ANSYS9.0. And based on the modal analysis theory and FEM technology, the free modal and the constrained modal analysis of the main parts were studied. Accordance to the analytical results, put forword methods to optimize the key parts.
本课题以XM18球面铣磨机为研究对象，为了提高其动态特性，本文主要从以下几个方面进行研究：首先，根据弹性力学理论和有限元分析的基本理论，利用ANSYS9.0软件建立了铣磨机的主要零部件床身、燕尾、燕尾座、主轴箱、扇形板和磨头座的有限元模型，利用有限元法对主要零部件进行了自由模态和约束模态分析，并根据分析结果对关键部件提出了改进方案。

The marginal division was a flat fan-shaped structure with a volume of (0.48±0.02) mm3, a maximum rostral-caudate axis of 1.6 mm, a maximum dorsal-ventral axis of 2.158 mm, and a widest axis (the diameter at lateral-medial coronal brain section) of 0.17 mm. The marginal division also moved progressively externally from the rostral section to the caudate section, but its scope was larger than that of others. The whole marginal division changed evenly from the rostral section to the caudate one. Its flat structure widened progressively and its dorsal-ventral diameter narrowed gradually and became plate-shaped.
边缘区呈现一个片状扇形结构，体积为(0.48±0.02) mm3，最大嘴尾径为1.6 mm，最大背腹径为2.158 mm，最大内外径为0.17 mm；同尾壳核和苍白球一样从嘴侧到尾侧随着脑平面的增宽边缘区亦逐渐向外侧移位，其移位的幅度亦明显大于脑平面增宽的幅度；整个边缘区从嘴侧到尾侧呈均匀变化，其片状逐渐变宽，长度逐渐变小，从而形成一个盘状结构。
