But you ought to recognize those history is full of 例子s of men and women who achieved outstandingness despite facing difficulties so steep those them easily have to HAs cruITd theirss spirit and left them lying in the dust.

但你必需认识到古代事件上有许多例子讲述在克服重重困难之后才获得胜利的人，那些困难之大足以使她们变得意志消沉，浮于尘世。

Thereupon he promoted Messer Ramiro d'Orco, a swift and cruel man, to whom he gave the fullest power.

他想使当地恢复安宁并服从王权，认为必需给他们建立一个好的政府，于是他选拔了一个冷酷而机敏的人物雷米罗·德·奥尔科，并授予全权。

Not only is that a good idea, it is necessary in order to achieve the performance advantage I promised. In order to make it work, though, you have to add a base case so that it doesn't recurse forever.

不仅是为了取得优势，一种好想法，它是必需的，为了使它工作，不过，你必须增加一种基础情况，因此它不永远递回。

The main disadvantage of this method is that the tannase comes into the tea and it has to be inactivated by a heat treatment, which is detrimental to the quality of the treated tea, or by a precipitation method which also impair s the quality of the tea.

这个方法的主要缺点是丹宁酶进入到了茶中，因而必需用热处理来使丹宁酶失活，或用沉淀的方法来除去丹宁酶，但这两种方法都会损害所处理的茶的质量。

Warn them about resting so as to stop them from becoming unhappy (although, as with anything else in the game, the players personality and mood at the time will determine whether this make him more or less happy), comment on their form to give them a much needed morale boost or a kick up the fuss.

提醒他们要休息可以防止他们变得不开心(尽管像游戏中的其它任何事情一样，那时运动员的性格和心情将取决于这事是否使他或多或少愉快)，给他们的状态作评论会提供大量必需的士气或者会引起他们的紧张。

This welding wire not only has the inherent properties of metal powder-cored wire, such as with better welding quality, without slag, highly efficiency and conveniently adjusting the alloying elements etc., but also has the advantage of low hardness in as-welded (less than HRC45), good machinability, high hardness in as-aged (more than HRC55) and better wear resistance with customary working procedure on making or repairing equipments such as rollers when reasonable designing the alloys content. The author adequately makes use of the high-tempering in the required stress relieving working procedure. During this working procedure, which causes the hardness of overlaying metal increased by the reason of austenite changes into tempered martensite and more chiefly what is the precipitation of a lot of carbide by secondary hardening simultaneously. This wire can solve the hard rolled problems of some solid wires with higher alloys while it can get over the conflict of existing overlaying materials what are always possesed high hardness with poor machinability or low hardness, good machinability with poor wear resistance. Further, it also can overcome the intenerating phenomena between welding beads and make the external hardness of overlaying metal uniform. Be sure it could be found important meaning in the overlaying of wear-resistant equipments, such as the precise roller.

该焊丝除了具有金属粉型药芯焊丝焊接质量好、无渣、高效率和合金成分可方便调节等固有的优点外，合理的设计粉芯中的合金成分，按通常工序制造与修复轧辊等设备，充分利用必需的消除应力工序的高温回火，堆焊层金属在奥氏体转变为回火马氏体的同时更主要是通过二次硬化析出了大量碳化物导致硬度增加，使得该焊丝还具有焊态硬度低(小于HRC45)、机加工性能好和时效态硬度高(大于HRC55)、耐磨性能好等优点，解决了某些高合金实芯焊丝轧制困难的问题，同时克服了现行堆焊材料硬度高、加工性能差或者硬度低、加工性能好、耐磨性差的矛盾，并能克服焊道之间的软化现象，使堆焊表面硬度较为均匀，对耐磨件，譬如精轧辊的堆焊具有重要意义。

The results indicated that the lignified seed shell had a negative impact on water permeability of seeds,but it was not the main reason for seed dormancy.

结果表明：(1)美国桂花种子木质化种壳对种子的吸水透性有一定的阻碍作用，但不是引起种子休眠的主要原因；(2)美国桂花种子的胚没有休眠，离体胚在光照培养7 d开始萌动；(3)胚乳被严密包裹的机械作用使胚无法获得萌发所必需的水分和氧气，这可能是导致种子休眠的最主要的原因。

As to these problems, a novel MBR named internal circulation membrane bioreactor is developed, in which the aeration not only supplies the required oxygen, but is utilized for the circulation of nitrified wastewater. It carries out the nitrogen and carbon removal of domestic wastewater in a single treatment unit. Simulated domestic wastewater is used in this research.

针对这些问题，本论文提出了一种新型的膜生物反应器——内循环式膜生物反应器，使曝气不仅为处理过程提供必需的溶解氧，而且实现脱氮过程中必要的混合液回流，实现了脱碳、脱氮过程在一个单体设备中完成。
