The cofinality of any ordinal ''α'' is a regular ordinal, i.e. the cofinality of the cofinality of ''α'' is the same as the cofinality of ''α''.

任何序数''α''的共尾性是正规序数，就是说''α''的共尾性的共尾性同于''α''的共尾性。

To all project practicality, the introduction is given to the operational characteristics, the methods for calculation and the researching actuality of the tail tunnels with sloping ceiling underground hydropower stations the Three Gorges. This paper has discussed in detail the characteristic method being the same with the compressive flow and the Priessmann solution being the same with the free-surface-pressure flow. And how to deal with boundary conditions has been expatiated. Also hydraulic transient process of tremendous load fluctuation in the tail tunnels with sloping ceiling has been numerical simulated and the Fortran program for numerical simulation has been given. The paper gain the maximal press for tail end of the shell, the maximal rising rate of rotational speed of generating set, the maximal vacuum degree for inlet of the tail tunnels and so on under 11 kinds conditions of tremendous load fluctuation. These conditions include the design conditions, the check conditions and the superposition conditions. Finally, the computing results have been analyzed and summarized. The end chapter is the general comment of the whole-length content and the describing of the intending view of researching.

Seven Brachionus species in Lake Jinghu were found, of which Brachionus calycflorus, B. angularis, B.diversicornis and B.forficula were determined as common species due to their higher population densities and occurrence frequency. The population density of both B.calyciflorus and B. angularis reached the peak in February and March and decreased rapidly after April, while that of both B. diversicornis and B. forficula remained high during June-September and decreased sharply after October.

结果表明，镜湖常见的7种臂尾轮虫中，仅萼花臂尾轮虫、角突臂尾轮虫(B.angularis)、裂足臂尾轮虫(B.diversicornis)和剪形臂尾轮虫(B.forficula)的种群密度和出现频率较高；前两者种群密度高峰期均出现在2~3月份，4月份后均较低；后两者种群密度在6~9月份较高，而在10月份后很快下降。

Methods Employing cholera toxin B-subunit combined horseradish peroxidase retrograde tracing technique and cholera toxin B-subunit combined colloid goldretrograde tracing with calcitonin gene-related peptideimmunohistochemical double-labeled staining technique,the innervation of musculus sacrococcygeus ventralis medialisin rats was studied.

大鼠骶尾腹内侧肌又称荐尾腹侧中肌(musculus sacrococcygeus ventralis medialis)或屈尾短肌，是位于盆腔后壁、骶椎前方的一对梭形肌肉，属尾肌群，因其功能似乎仅为屈尾，故至今尚未引起人们的注意，而与该肌位置关系较密切的会阴肌因在某些运动神经元疾患时仍可保持其正常生理功能而一直受到神经工作者的关注，尤其是近年来有诸多文献报道了会阴肌的神经支配、相关神经元的细胞构筑、神经递质和神经调质的分布以及纤维联系特点［1～10］，藉以探讨运动神经元疾病的神经病理学。

The tailward flow tends to move from the duskside and dawnside to the nightside, and becomes stronger while moving away the Earth. From 1, Jul. 2004 to 31, Nov. 2004, TC1 satellite explored 516 tailward flow events between 7RE to 13RE, which the duration exceed 3 min.

与来自中磁尾的地向流相比，近地磁尾近赤道区域来自电离层的尾向流具有低温高密特性。2004年7月1日至2004年10月31日期间TC1卫星在近地磁尾（7RE～13RE之间，RE为地球半径）观测到持续时间超过3 min的尾向流共516起。

The statistic results showed that: Compared with the earward flow from the midtail, the nearEarth low latitude tailward flow from the ionosphere is characteristic of the lowtemperature and high density; With the tailward flow moving from the lobal region to the plasma sheet, the velocity of the tailward flow decrease, the density and the temperature increase. The tailward flow has distinct anisotropy depending on the difference of the parallel with perpendicular temperature.

对这516起尾向流的统计研究结果显示：（1）尾向流在从等离子体片边界层向等离子体片的运动过程中流速会逐渐减弱、密度逐渐增高，温度有逐渐下降的趋势；（2）对尾向流平行温度和垂直温度的分析显示不同等离子体区域的尾向流都有较明显的各向异性；（3）在从等离子体片边界层向等离子体片的运动过程中，尾向流逐渐趋向各向同性。
