共尾的

The cofinality of a set of ordinals or any other well ordered set is the cofinality of the order type of that set.

序数或任何其他良序集合的集合的共尾性是这个集合的序类型的共尾性。

All superclasses of closed unbounded classes are stationary and stationary classes are unbounded, but there are stationary classes which are not closed and there are stationary classes which have no closed unbounded subclass ( such as the class of all limit ordinals with countable cofinality ).

所有闭合无界类的超类是固定的并且固定类是无界的，但是有着不闭合的固定类并且有着没有闭合无界子类的固定类(比如带有可数共尾性的所有极限序数的类)。

For example, the cofinality of ω is ω, because the sequence ω·''m''( where ''m'' ranges over the natural numbers ) tends to ω; but, more generally, any countable limit ordinal has cofinality ω.

例如，ω的共尾性是ω，因为序列ω·''m''(这里的''m''取值于自然数之上)趋向于ω；但是，更加一般的说，任何可数极限序数都有共尾性ω。

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。

The parasitic larval stage of the tapeworm Taenia multiceps that consists of a cyst in which the scolex develops and that infects the central nervous system of ruminants, especially sheep.

共尾幼虫绦虫多节绦虫的寄生虫幼虫阶段，有囊胞，头节在其中生长，使反刍动物尤其是羊的中枢神经系统感染

Of all the wild animals in their area, none was more useful to the Delaware tribes than the Virginia white-tailed deer: it was a source of meat, and its hide was used for clothing,第 20 页(共 101 页) its antlers and bones for tools, and its sinews and gut for bindings and glue.

所有野生动物中在他们区域/对 Delaware 部落最有用的是/ Virginia 白尾鹿：/它是肉的来源/它的皮可以做衣服/鹿角和骨头可以做工具/肌腱和肠子可以做捆绳和胶。*这句话的条理很清楚，很容易理解句子的大意。

Bristlecone Pine 狐尾松 Bristlecone Pine, common name for a cone-bearing evergreen tree native to high, dry mountainous areas in the western United States.

狐尾松是一类生长在美国西部干燥高山上的结松果的常绿树木的共称，因为松果上的鳞片长得像狐尾而得称。

Aeruginosa and S. quadricauda in HAC were lager than in HA without reference to pure or mixed culter. It indicated that the growth of M. aeruginosa and S. quadricauda need HCO3(superscript -) as carbon source to balance its C:N:P ratio. Cyclotella sp. could not survive in HAC. M. aeruginosa and S.

铜绿微囊藻与四尾栅藻在HAC中纯培养和共培养的生物量K和最大增长速率r均远大于在HA中，表明这两种藻的增殖需要HCO3作为碳源平衡胞内营养平衡；小环藻不能在有HCO3的培养基中生存。

Many nanotwins were formed in this triangular region. HREM observations showed that nanotwinning dislocations were nucleated at noncoherent twin boundaries with the local stress concentration, and the nucleation is related to the dislocation dissociations at the boundary ledges. The proceeding of these nanotwins is the homogenous shears of 1/6 [11〓] twinning dislocations, which is that the trailing 1/6 [112] twinning dislocations repel the leading twinning dislocations to proceed in the (111) planes. Therefore, twinning dislocations at the twin tip appear to be on one side of twin, forming a noncoherent twin boundary with a semilenticular shape.

在此三角区域内发现许多纳米孪晶的存在，通过高分辨电镜手段观察到纳米孪晶中的孪生位错是在具有原位应力集中的非共格入射孪晶界上形核的，纳米孪晶的形核与界面的台阶位错及其位错分解反应有关，纳米孪晶的行进是1/6[11〓]孪生位错均匀切变机制，即每一个（111）孪生面上对应一个孪生位错，其中拖尾的1/6[11〓]孪生位错将会推动领先的孪生位错行进，于是在形变孪晶头部位置的孪生位错排列常常出现在形变孪晶的一侧界面，形成一个半透镜状的非共格孪晶界。

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。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
