难以理解的

Oh,my dear,thanks very much for your hard work.they are golden saying .i recognize their value and understand their although it is difficult to execute,i will try,because i catch on the advantage.

奥，亲爱的老乡，非常感谢你的辛勤劳动，这些都是金玉良言；我意识到他们的价值，理解他们的内涵，因为我知道他们的好处，尽管难以付诸行动，但我还是会努力的。

Liberty cannot be preserved without a general knowledge among the people, who have a right, from the frame of their nature, to knowledge, as their great Creator, who does nothing in vain, has given them understandings, and a desire to know; but besides this, they have a right, an indisputable, unalienable, indefeasible, divine right to that most dreaded and envied kind of knowledge; I mean, of the characters and conduct of their rulers.

如果人民没有一般的知识，自由就难以得到维护。人民有天赋获得知识的权利，因爲无所不能的伟大造物者已经赋予他们理解能力和求知的欲望。但是，除了这种权利之外，他们还有一个权利，一个无可争议、不可让与、无法废除的神圣权利去获取最令人畏惧和羡慕的那种知识，我指的是了解他们统治者的品质和德行。

There are linguistic reasons too why spelling reform is tricky to undertake. Written language is more than a phonetic version of its spoken cousin: it contains etymological and morphological clues to meaning too. So although spelling English more phonetically might make it easier to read, it might also make it harder to understand.

拼写改革之所以难以推行也有着语言学本身的原因，毕竟语言的书写系统不仅仅只是记音的符号，它本身还具有与语义相关联的语源学以及形态学上的线索，所以英文拼写由单词读音决定虽然解决了读音的问题，但是这种拼写理解起来可能更难。

In the recent 10 years, at the three special fields of dynamic aerodynamics, although the circumferential Reynolds number gap between wind tunnel free flight and its corresponding real flight is as high as one or two magnitudes, wind tunnel free flight experiment results succeed in predicting or reproducing the dynamic aerodynamic characteristics in the three special fields, which appear in the real flight phase producing severe effects on flight security and flight performance.

近10余年来，在3个动态气动专题领域内，地面风洞自由飞实验与对应的天空飞行器的绕流雷诺数虽然相差1～2个量级，但风洞自由飞实验结果多次预测或再现了天空飞行器出现的对飞行安全、飞行性能产生严重影响、其它地面风洞实验方法难以预测或再现的这3个专题领域内的动态气动特性，这至少为3个专题领域内天地动态气动相关中的雷诺数影响，提供了一个新的理解。

There are excessive and unorderly rules produced by traditional association rule mining, many of which are redundant. It is difficult for users to understand and use.

摘要传统关联规则挖掘得到的原始规则集包含大量的、杂乱的规则，其中很多是冗余的，这样的规则集难以被用户理解和应用。

However, the piercing flavour of LuHsun"s essays made his essays subject to censure by many critics. And LuHsun himself was often mistaken and refuted by the compromising ones because of his sharping critical attitude toward one vital part but ignoring the other aspects of the objects. Especially those readers who never read the articles by LuHsun"s counterparts would think him too harsh, but the value of LuHsuns essays could be uncovered sufficienty by contrast to those by the counterparts.

鲁迅杂文深刻犀利的文风也多受指责；其对生活、社会问题看法超出一般人的理解范围而受误解；其只抓要害、不及其余以及连类而及，对具象的类型化批评的论辩方式为中庸、和为贵的受众所指责，尤其是难以见到鲁迅论辩对手文章的读者，更会留下刻薄的印象，因为鲁迅的现实性极强的杂文与对立之文共存才显现它的价值。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
