难完成的

Although some of us find the task more difficult than others, most of us perform it rather effortlessly.

虽然我们中的某些人发现自己的工作比别人的难，但是大多数人都可以毫不费力的完成。

The Activated Ploy-oxygen Aerator adopts magnetic engineering technology to send the oxygen of air which is gathered and activated by polyoxier to the mixing chamber of main engine under water, and the process of water and oxygen synthesization is finished rapidly by the use of magnetizer and activated oxygen enriched air under water, which has been cut into tiny air bubbles by the high-speed rotated propeller of the mixing chamber in the process of water and oxygen synthesization, which can increase the affinity of water and oxygen. When flow rate of water is more than the buoyancy force of the tiny air bubbles, it is difficult for the tiny air bubbles to float on water in short time and the tiny air bubbles can stay in water for longer time, which can increase the efficiency of water dissolving oxygen and make the power efficiency of the machine is greater than traditional aerator obviously.

聚氧活化曝气增氧机采用磁性工程技术，将空气中的氧经聚氧器聚集活化后送到水下主机的混合室，由水下的磁化器和活化富氧空气快捷完成水气合成程序，在水气合成过程中已被混合室内高速旋转的离心叶轮切割成微小气泡，这些随射流、射向水下方的小气泡，其动能消耗至零后，在水中的浮力作用下、开始缓慢上升，由于提高了水与氧亲合力的小气泡只靠浮力沿着螺旋型的曲线缓慢浮升，这些小气泡在短时间很难浮上水面，因此延长了小气泡在水中的停留时间和行走路程，大大提高水中溶解氧的效率，使该机的动力效率明显高于传统曝气装置。

However, historians have traditionally disagreed as to whether the skin Hercules is portrayed wearing in such works of art is that of the Nemean Lion or that of different lion entirely……one which Hercules is said to have killed when he was eighteen years old.

希拉当然不会因为一次失败就放弃杀死赫五力，她故意让赫五力发疯候打自己的妻子，赫五力醒了以后十分懊悔伤心，决定要以苦行来洗清自己的罪孽，他来到麦西尼请求国王派给他任务，谁知道国王受希拉的指使，果然赐给他十二项难如登天的任务，必须在十二天内完成，其中之一是要杀死一头食人狮。

By way of four complete reflex arcs of comparative test and destroyed reflex arcs,it is showed that the reflex arc consists of sensory receptors,efferent nerve fibers,nerve center,efferent nerve fibers,effecter,and that the four parts must exist together.The test phenomenon is clear after improving the experimental methods,and the rate of success reaches 95%.

从各类实验教材来看，我们发现其证明传入神经和传出神经是反射弧的组成部分的方法有些过于简单[1~3]，不能区别传入神经和传出神经的功能效应；有的使用普鲁卡因麻醉坐骨神经干[4]，麻醉的时间和程度不好把握，很难圆满完成实验，造成实验失败。

But on the other hand,this true world in which they are living is not as ideal or satisfying as that they expect, therefore, they are always yearning for a kind of force to save or transform this unideal true world and as we all know, in their minds and souls those comic superheroes are the avatars of that superforce they are dreming of, that's why our fascination with comic superheroes is time-tested.

我们常常会遇到这样那样的事一时无法解决，或着很难用正常的途径来解决，我们又不愿去做那些违法的行为，尽管那样做是合情合理的，我们会借助英雄帮我们来完成心愿。但是这些都是我们的美好愿望，事情还要靠我们自己来解决，用他们来调剂一下心情，放松一下还是不错的选择。

I will be missing you Yeah,this right here Goes to everyone that has last someone Come on ,check it out Seems like yesterday we used to rock I laced the frack you lock the flow So far hanging on the block for dough No\'torious they got to know That life ain\'t always what it seems to be Words can\'t express what you mean to me Even though you\'re gone .

我会在你失踪是啊，这个权利在这里云向所有人说，已经过去有人来，签出好像昨天，我们用岩石 i费城该frack你锁流至今悬挂在块面团 no'torious他们，也认识生活并非总是什么它似乎是话不能表达你的意思，我即使你走了，我们仍然有leam 通过你的家人，我会完成你的梦想在未来不能等待，看看如果你打开了闸门，箱缅怀一段时间，晚上他们设法阻止它，但它再次扮演当其真正的感情难以隐藏不能形象的所有痛苦，我觉得去做听到一半，你的呼吸我知道你仍住你的生活后死亡每走一步，我，一举一动，我每一天，每一次我祷告我会失踪你思想的一天当你来到远离什么是人生采取什么乐队打破我会失踪你这是一种很难与你不要靠近我知道你在天上微笑着下降在注视着我们，而我们祈祷，为你我们每天祈祷，为你直到一天，我们再次见面在我心中，是我让你的朋友回忆给我的力量，我需要实力，我要相信我的想法b.i.g。

Industry gain guest is only after all a kind additional the market is politic, can bringing how old brand value and immediate profit realize appraise numerate very hard, because this can not serve as the task to ask every stuff will press a quantity to finish on time normally, however employee the interest according to oneself, draw up oneself place sees place want, share with oneself user.

企业博客究竟只是一种辅助的市场策略，能带来多大的品牌价值和直接收益是很难实现估算出来的，因此通常并不会作为任务要求每个员工来按时按量完成，而是员工根据自己的爱好，写出自己的所见所想，并与自己的用户分享。

Despite having climbed only four years, Chis may very well be the best sport climber in the world. Recently, Chris astounded the climbing establishment with a second place finish at the World Championships, possibly the single most prestigious climbing event in the world. In the month previous to the event, Chris completed the hardest boulder problem on American soil,"Crown of Aragon"(V13), climbed two 5.14a's in a day, and onsighted

虽然只有四年的经验，Chris 很可能是世界上最棒的攀登著，最近他让人吃惊的在世界锦标赛拿到第二名，可能是世界上最有威望的事迹，在之前的一个月，Chris完成美国境内最难的抱石路线&Grown of Argon&(V13)，一天爬两条5.14a的路线（几乎是onsighting第一条，onsighted程度

Considering the low efficiency of current Web services processing,the paper suggests that the demands of requesters be represented as Service Template in forms of constraint by adding ample semantic description to Web services,and then ST is matched with Service Advertisements which have been published and saved in enhanced UDDI library,so we can get a set of candidate services,at last,we can find an optimal service from this set.

1引言目前，各个公司和研究机构都在寻求比较优化的Web服务处理的方案，由于这些方案缺乏对服务语义的详尽描述，这样在服务处理过程中可能导致下列问题：(1)在Web服务处理过程中，不得不通过静态绑定Web服务来完成相应的业务处理；(2)很难改变现存的设置以便协调新的Web服务处理；3
