Because gas constitutes only a few percent of the mass of spiral galaxies , modelers had neglected it to make the simulations more tractable 由于气体只占螺旋星系质量几个百分点，研究人员为使模拟较容易处理而将之省略。
4 . the generation of flow chart . based on vc - h - 6 . 0 ' s strong graphic fimction , it makes possible for users to generate intuitionistic and tractable flow chart 流程图的生成，利用vc + + 6 . 0功能强大的图形建模技术使用产能够生成直观、操作方便的流程图。
In this paper we present a method to group adjectives according to their corpora distribution , based on the machine tractable dictionary of contemporary chinese predicate adjectives 摘要本文提出了一个基于现代汉语述语形容词机器词典以及平衡语料库的形容词多信息聚类算法。
Mathematicians are familiar with this ; common problems in algebra are more tractable when considered over the complex numbers than over the reals , even though complex arithmetic is more difficult 数学家对此很熟悉；如果将代数中的常见问题考虑成复数而不是实数时，那么这些问题就更容易处理，尽管复数算法较难。
If i had let him stay there three or four days without food , and then have carry d him some water to drink , and then a little corn , he would have been as tame as one of the kids , for they are mighty sagacious tractable creatures where they are well used 如果我让那头老山羊在陷阱里饿上三四天，不给它吃东西，然后，再稍稍给它点水喝，给它点谷物吃，它也一定会像那些小山羊一样驯服。只要饲养得法，山羊是十分伶俐十分容易驯养的。
To women who please me only by their faces , i am the very devil when i find out they have neither souls nor hearts - when they open to me a perspective of flatness , triviality , and perhaps imbecility , coarseness , and ill - temper : but to the clear eye and eloquent tongue , to the soul made of fire , and the character that bends but does not break - at once supple and stable , tractable and consistent - i am ever tender and true “对那些光靠容貌吸引我的女人，一旦我发现她们既没有灵魂也没有良心一旦她们向我展示乏味浅薄，也许还有愚蠢粗俗和暴躁，我便成了真正的魔鬼。但是对眼明口快的，对心灵如火的，对既柔顺而又稳重既驯服而又坚强，可弯而不可折的性格我会永远温柔和真诚。 ”
