And we show that random walk model converges to the stable law of Lévy-Feller advection-dispersion equation by use of a properly scaled transition to vanish-ing space and time steps,We propose an explicit finite difference approximation for Lévy-Feller advection-dispersion equation.

第三章讨论描述服从某种稳定分布反常扩散的非对称空间分数阶对流-扩散方程——Lévy-Feller对流-扩散方程，首先利用Fourier变换和Laplace变换给出方程的基本解，然后利用Grünwald-Letnikov分数阶导数移位离散算子离散方程中的Riesz-Feller分数阶导数得到离散格式，证明此格式可以解释为离散随机游走模型，并且证明了当时间和空间步长以一定的比率同时趋于0时，所提出的离散随机游走模型收敛到Lévy-Feller对流-扩散过程的稳定分布。

Once there was a little fish named Finny.

有一天。小鱼 finny 他自己在海里面游来游去。。。。。

The birds fly", soaring in the skies are not caught with nets, archery bow could not use, is extremely safe, but in order to "bulimia" from high-altitude flying, the shooting death arrested;"abyss of fish , open in the deep water, the fish fork stabbed not, could not catch fish hooks, can be said to be extremely safe, and an incense in order to bait, however, they swim to the surface of the water, fish fork was stabbed to death by the fish hook钓起, the food table as a fisherman.

高飞之鸟"，翱翔于晴空之中，用网捕不到，用弓射不着，可谓安全之极，可是为了"贪食"却从高空飞下，即被捕射而亡；"深渊之鱼，游憩于深水之中，渔叉刺不上，渔钩钓不着，可说是安全之至了，然而为了一口香饵，却游向水面，结果被渔叉刺死，被渔钩钓起，成为渔人佐餐的佳肴。

This hapless fish, sometimes called "poison flute", is wretchedly equipped for locomotion; his useless tail and a stiff tubular body are handicaps for which he compensates by wildly agitating his pectoral fins to move forward and backward.

这种不幸的鱼，行动不方便得令人可怜。它那没有用处的尾巴和那僵硬的管状的身体成为了它四处游动的障碍，于是它只能激烈地鼓动着小鳍以便游来游去。

A Little Boy How I never could be tired with roaming about that huge mansion, with its vast empty rooms, with their worn-out hangings, fluttering tapestry, and carved oaken panels, with the gilding almost rubbed out---sometimes in the spacious old-fashioned gardens, which I had almost to myself, unless when now and then a solitary gardening man would cross me---and how the nectarines and peaches hung upon the walls, without my ever offering to pluck them, because they were forbidden fruit, unless now and then,---and because I had more pleasure in strolling about among the old melancholy-looking yew-trees, or the firs, and picking up the red berries, and the fir-apples, which were good for nothing but to look at ---or in lying about upon the fresh grass, with all the fine garden smells around me---or basking in the orangery, till I could almost fancy myself ripening too along with the oranges and the limes in that grateful warmth-or in watching the dace that darted to and Fro in the fish-pond, at the bottom of the garden, with here and there a great sulky pike hanging midway down the water in silent state, as if it mocked at their impertinent friskiness,---I had more pleasure in these busy-idle diversions than in all the sweet flavors of peaches, nectarines, oranges, and such like common baits of children.

The concept of cash pawnshop is for the fictitious money of bleed white players, theoretic, free game is strong arisen when, give the person's impression and all without exception is elegant, and the existence that many criticize viewpoints denied this kind of play thoroughly, then the net swims operation business can swim in free net only in add this one element, cash pawnshop shows itself gradually, make nowadays mainstream trend.

现金当铺的概念是为了榨干玩家们的虚拟货币，理论上，免费游戏刚兴起时，给人的印象并无不雅，而不少批驳观点则彻底否认了此类游戏的存在，于是网游运营商只能在免费网游中追加这一因素，现金当铺便逐渐脱颖而出，成为时下主流趋势。

Then I'm going to buy a new swimming suit and goggles

每隔一天我就可以在泳池游来游去了。

I like my goldfish because I like .

我喜欢金鱼，因为我喜欢看它游来游去。

Williams claimed to have collected ancient knowledge in a "Gorsedd of Bards of the Isles of Britain" he had organized, but in the 1970s, draft manuscripts of the texts were discovered among Williams' papers, exposing the texts as his own compositions.

威廉斯声称在他组织的"英国爱尔兰吟游诗人吟游诗集会"已经收藏有古代知识，但在上世纪七十年代，文献的草拟手稿被发现在威廉斯的论文里，暴露了手稿是他自己的杰作。

Groper - Whenever the opportunity presents itself, these harassers' eyes and hands begin to wander, engaging in unwanted physical contact that may start innocuous but lead to worse.

猪手游走型：一旦机会来临，这类骚扰者的眼睛和手就会四处游走，未经许可地触碰别人的躯体，开始可能只是无伤大雅的无意识动作，然后就会得寸进尺。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
