We study the relation between topological sigma models and generalized geometries. The existence conditions for the most general type of topological sigma models obtained from twisting the N=(2,2) supersymmetric sigma model are investigated, and are found to be related to twisted generalized Calabi-Yau structures. The properties of these topological sigma models are analyzed in detail. The observa....

六标准差从1987年在摩托罗拉公司推行至今，已近20个年头，从一开始制造面的改善，延伸到非制造性的企业流程当中，它不但有效地变化员工能力与态度，也为企业带来突破性的营运改善，全方位提升企业竞争力；但事实上，六标准差管理活动导入对企业是一大变革性的挑战，因为其中牵涉策略、组织。。。。

My heart had been tramping. Up to tonight, it had been uneven and slow 25 years.

我的心在走路，它慢慢地走过了二十五年，一直到这个夜晚。

Upon his death in 1504, it was revealed that Bost had willed a sum of money that, properly invested, was earmarked to provide tuppence a year in perpetuity for each of Eton's "collegers." Collegers are boarding students whose families live far away; the remainder are town boys or "oppidans."

到他1504年去世为止，据显示鲍斯特的遗嘱里，已经将一笔钱作为投资，并且指定永久性地每年提供给每个伊顿的"资助生"两便士（资助生是家住得较远的寄宿生，余下的则是城市子弟或者是"走读生"）这笔钱用来保证这些孩子会有足够的吃的。

The subject which had been so warmly canvassed between their parents, about a twelvemonth ago, was now brought forward again.

大约在一年以前，父母曾经热烈地争论过这个问题，如今又要旧事重提了。

They invaded China and took over the capital on December 13, 1937. Two hundred to three hundred thousand people died in a couple of weeks.

他们侵略中国并且在1937年12月13日占领了首府，在几个星期内，有二十万到三十万的居民惨遭杀戮，这比历史上我们所听到地任何一场战争都要剧烈

Yet the museum has another ambition: to cement the claim that Hergé, who died in 1983, was an important artist in his own right, whose talents as a graphic designer, painter and typographer were "somewhat eclipsed by the runaway success of 'The Adventures of Tintin'," to quote one oddly grudging sign on display.

建造博物馆还有另一个目的：让公众知道1983年逝世的埃尔热本身还是一位重量级的艺术家，他在设计、绘画和排版上也很有天赋，但正如一块展览牌上颇不情愿地写的："被《丁丁历险记》的大获成功掩盖了"。

He argued that the three laws' unconstitutionality was not "clearly established": not only did the statutes deserve a "presumption of constitutionality",[30]but at least one statute, 750.170, had also been enforced within the past decade [31] and had survived two previous constitutional challenges.

他称道，这三项法律违宪性是没有"清晰地界定的。"不仅法令应该获得"合宪性的假定"，[30]而且至少有一项法令，即 750.170在过去十年里得以执行，并在此前两词合宪性的挑战中保存下来。

His first published work,"The Voyage of the Beagle," is a tidied-up version of the log he kept on the five-year trip around the world, and he is unflaggingly meticulous in his observations of the plant and animal life he saw or collected along the way.

他出版的第一本书《小猎犬号见闻录》，是一本经过整理的他周游世界五年的航海日志，他对沿途看到或收集到的动植物做了坚持不懈地细致观察。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
