The default sort that Perl uses just sorts ASCIIbetically, where "í" comes not just after "u", but actually after all the unaccented letters.

通常 Perl 总是使用 ASCII 的顺序来排序，这样"i"不是紧紧的排在"u"后面，而是在所有混音字母以后。

Older versions of Condor used a U in the status column to stand for unexpanded.

Condor的早期版本在状态栏中还使用U表示未扩展状态。

Next,similar to the studies of Friedland-Hersonsky inequalities in norm form and Martininequalities for discrete groups of 〓,we establish 〓 type inequalitiesfor subgroups of unitary transformation group U(1,n,C)in complex hyperbolicspace 〓 and we also give several 〓 type inequalities in the form of fgfg〓for the norm algebra 〓 in C.

其次，我们对复双曲空间〓上的酉变换群U(1，n，C)的子群建立了〓型不等式，推广了Martin的相应结果。最后，我们对复数域C上的范数代数〓建立了形如〓的〓型不等式，推广了Friedland-Hersonsky不等式。

Each of its 8 joints with 2-DOF was an universal coupling with "+" shape and their motion range is over ±60 degree."U" form components constructed two rotatory DOF that their rotary range was adaptive to human whist.

由两个 U形构件组成手腕的两个转动自由度，它们的运动范围与人的手腕运动范围相适应，在这个机构的工作空间内没有奇点，具有平动和转动解耦的特性，最后一个自由度是手控器手指关节的运动。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
