The influences of the shock thickness and Alfven waves on the particle acceleration by diffusive shock waves are numerically studied through solving one-dimensional diffusive equation including the second-order Fermi effect. It is shown that the spectral index of the energetic particles strongly depends on the shock thickness. For example, the spectral index increases from 2.1 to 3.7 in the low energy range of 3-10 MeV and from 2.5 to 5.0 in the high energy range of 20-60 MeV as the thickness increases. The spectral index decreases from 4.3 to 3.1 as the particle injection energy increases. The spectral index decreases from 4.0 to 1.8 at the quasi-steady stage with the enhancement of the compression ratio from 2 to 4. The results indicate that under the influence of Alfven waves, the energetic particle spectrum at lower energy becomes flat and the spectral index decreases from 2.5 to 0.6 in the low energy range of 3-10 MeV and from 11.6 to 5.0 in the high energy range of 20-60 MeV. At the same time, the rollover energy reaches 19.6 MeV. The spectral index decreases from 5.8 to 2.9 as the energy density of Alfven waves increase. All these results are basically consistent with the theoretical models, as well as the observations of typical energetic particle events.

通过数值求解包含二阶费米加速的一维扩散方程，探讨在准平行激波条件下激波厚度和级联阿尔芬波对粒子加速的影响，研究粒子分布函数的演化与激波厚度和阿尔芬波强度的内禀关系，计算结果表明：(1)考虑激波厚度时，谱指数明显依赖于激波厚度，随着厚度从0.32增大到2.56，低能端(3-10MeV)谱指数逐渐从2.1增加到3.7，高能端(20-60MeV)谱指数从2.4增大到5.0，能谱逐渐变软；当初始注入粒子动量增大1.3倍，质子能谱指数从4.3减小到3.1，且与零厚度激波加速的谱指数差值缩小；厚度不变时，随着压缩比从2增加到4，准稳态分布时低能端(3-10MeV)粒子能谱指数逐渐从4.0减小到1.8谱变硬；(2)在级联阿尔芬波的影响下，随着时间的增大，粒子在低能处(3-10MeV)的谱指数从2.5减小到0.6高能端(20-60MeV)谱指数从11.6减小到5.0，能谱变硬，拐点能量值从7.5MeV增大到为19.6MeV；随着波的能量密度增大，谱指数从5.8减小到2.9，这表明阿尔芬波强度越大，加速效率越高，通过与激波厚度解析结果和高能粒子事件的观测能谱比较发现两者是一致的，说明数值模拟结果是可靠的。

I had done a similar thing in, in Central Station where as we were on the road and when we saw the religious processions in that part of Brazil, we soon incorporated them into the film and it didn't exist in the original screenplay either and here the boy started to imitate, you know, as we went back and forth to the location and the animals were there, he started to imitate all of them and then suddenly we started to incorporate that as well, er, same thing with the fire-eater, when she started to show us what she could do, we, we immediately started to, you know, to organically incorporate those elements into the screenplay and that is really a fascinating part of our film, it's the collaborative aspect of it, you know, it's when you realise that without every single person's input, the film wouldn't be the same and this is what really makes cinema depart from most medium, is that you have to accept it's democratic quality, you know, essence in order for a film to really be alive and interesting to watch, I guess.

唔，有趣的是当卡戴尔看完电影就跑来对我说，你知道吗这是最忠于原著的改编版，可很多元素都不同，最后，我认为当你改编小说时，当你把文学转化成电影时，真正需要重视的是小说精髓之处，这比什么都要紧，并且创造出一种两者如对立沟通式的对白而不只是改编，ipsis literis，你知道这书，运用他作为深刻的灵感来源，他允许你探究，你知道，没有素材来源不可能投入进去，有次我看库布里克的访谈，其中说到他偏爱主人公容易塑造的小说而不是小说本身，如此他就能专注于故事构架和情节而不是依照原本，这我可以明白，但换个角度说，如果我自己没有被故事打动，如果是这样，故事无法让我产生共鸣那进行二次创作很困难，因为人物本身就显得很单薄无法定位和改编，但我真的能理解他的感受。

There was an increasing demand for engine power due to industrial development. As early as the 2nd century BC, the ancient Greeks invented an engine that was powered by the reaction from spurting steam; in 1690, the Frenchman Barben invented the first piston steam engine. On the basis of his predecessors' work and with his own hard work and numerous trials and failures, James Watt invented the steam engine with connecting rod, flywheel and centrifugal speed governor in 1782.In 1784, the British government granted a patent to James Watt for producing steam engines, which signified that man had entered the age of the steam engine and also significantly expedited the beginning of the Industrial Revolution in 18th century Europe. By the 1830s, steam engines had been widely used in various sectors such as textile, metallurgy, coal mining and transportation; for example, the American Robert Fulton invented the steamboat and the Englishman George Stephenson invented the steam locomotive.

随着社会的进步，社会由农业时代进入工业时代后，对全用手工操作已十分不满足，人们随着工业发展对动力的需求日益突出，瓦特在前人研究蒸汽的基础上，甚至早在公元前二世纪，古希腊人创造的一种利用蒸汽喷射的反作用的发动机，以及1690年法国人巴比首先发明第一台活塞式蒸气机等，刻苦钻研，反复实验，经历无数次挫折和失败，终于在1782年发明了具有连杆、飞轮和离心调速器的双动作蒸气机，使之成为了可以实用的蒸气机。1784年英国政府授予瓦特以制造蒸气机的专利证书，这标志着人类进入了蒸气机时代，有力地促进了欧洲18世纪的产业革命。

Alas, I sold my entire GEICO position in 1952 for $15,259, primarily to switch into Western Insurance Securities. This act of infidelity can partially be excused by the fact that Western was selling for slightly more than one times its current earnings, a p/e ratio that for some reason caught my eye. But in the next 20 years, the GEICO stock I sold grew in value to about $1.3 million, which taught me a lesson about the inadvisability of selling a stake in an identifiably-wonderful company.

可惜的是，在1952年我以15，259美元的价钱将全部的GEICO股份出清，然后将所得资金投入到西方保险证券公司之上，这项变心的举动，一部份的原因是因为西方保险证券当时的股价相当吸引人，本益比只有一倍左右，然而在往后的二十年间，当时被我卖的的GEICO股份的价值却成长到1，300万美元，这样的结局让我体会到绝对不能卖掉一家明显的好公司的原则。

And now we are entering the phase of realization, we have normally done the psychological term, meaning that cerebrally we viewed and created from point A to point Z materialization, we have included the setup and operating procedures, steps, possibly reflections from the past, the possible trajectory corrections, these should convey information to and understanding of stakeholders, it must then provide, or the places to be occupied by the human element taking into account the position of each, the latter being the respect that ought to others, one who is better known than ten who are seeking a man is in warn two, it is because of these quotes that we can achieve good coordination, the latter resulting in consistency, these elements combined allow consistency, this set could be called planning in the material for what is my theory all elements generated by our being and our published by externalizing should go through this journey, if these conditions are met and adhered I can not speak in terms of planning, but Love.

现在，我们正在进入第二阶段的实现，我们通常是心理而言，这意味著 cerebrally我们认为，创造了从 A点到Z点物化，我们已包括设置和运作程序，步骤，可能是从过去的反思，改正可能的轨迹，这些应该传达的信息和了解利益相关者，它然后必须提供或地方被占领了人的因素考虑到每个位置，后者是应该尊重别人，一个更好地了解谁是谁比10寻求一个男人在警告二，这是因为这些报价，我们能够实现良好的协调，后者导致的一致性，这些因素结合在一起，使一致，这一组可称为规划的材料什麼是我的理论所有元素生成我们正在和我们出版的外部化，应通过这个征途上，如果这些条件得到满足，并坚持说，我不能在规划方面，而是爱。

Data pre-processing technologies such as singular points elimination, registration and radius compensation are studied. Base on chord high difference algorithm, a new one called chord high difference-ratio algorithm is proposed to improve veracity and robusticity of singular points elimination. Then, a registration algorithm based on local surface reconstruction is proposed, which avoids infaust influence coming from single reference point error.

Now Guy, who had counted on outnumbering Robin's men by two to one, saw outlaws swarm out from the forest depths to watch over their leader, and knew himself and his men outnumbered, while already he had seen how deadly were the arrows of his opponents.

现在盖计算他的人二比一超过罗宾的人，他看见亡命之徒从森林深处涌出，注视他们的领袖，知道自己和他的人超过他们，而早就看过他的对手的箭如何的致人于死命。

The panorama passed before their eyes like a flash, save when the steam concealed it fitfully from the view; the travellers could scarcely discern the fort of Chupenie, twenty miles south-westward from Benares, the ancient stronghold of the rajahs of Behar; or Ghazipur its famous rose-water factories; or the tomb of Lord Cornwallis, rising on the left bank of the Ganges; the fortified town of Buxar, or Patna, a large manufacturing trading place, where is held the principal opium market of India; or Monghir, a more than European town, for it is as English as Manchester or Birmingham, with its iron foundries, edge-tool factories, high chimneys puffing clouds of black smoke heavenward.

这一切景物，象闪电般一掠而过，有时被一阵浓浓的白烟，遮盖得模糊不清。沿途，旅客们只能隐约地看见：距贝拿勒斯城东南二十英里的比哈尔历代土王城寨——舒纳尔堡，加兹铺和这个 www.8 ttt8。 com 城区一些8 tt t8.com 制造玫瑰香水的大工厂；以及印度主要的鸦片市场——巴特那，还有那个比较欧化和英国化的城市——蒙吉尔，它很象英国的曼彻斯特或伯明翰，以冶铁、制造铁器和刀剑驰名。那些高大的烟囱喷吐着乌黑的浓烟，把整个卜拉马活佛的天空搞得乌烟瘴气。在这个 www.8 ttt8。 com 梦里天堂似的国度里，这些黑烟真是大煞风景。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
