Since the multiple scattering should be considered, the scattering problem of many-cylinders is more complicated than single cylinder. By using scattering matrix method to solve the scattering problem of many-cylinders, first we have to express the incident fieldand scattered field by special function（for example, Bessel function and Hankel function）under cylindrical coordinate, then use the addition theorem of special function to get a linear system of equations to relate the incident field coefficients and scattered field coefficients. The incident and scattered field coefficients for every cylinder can be solved from the linear equations by matching electromagnetic boundary condition pointwisely.

单颗圆柱散射体的散射场解析解很早就被解出，而多个圆柱阵列的散射场问题因为涉及到入射光在圆柱与圆柱间的多重散射，故散射行为较单颗圆柱的散射复杂，因此圆柱阵列的多重散射问题需要利用加法定理来处理；散射矩阵法的主要精神即是先用圆柱座标下的特殊函数对平面波和圆柱散射体的内外域电磁场做无穷级数展开，再藉由特殊函数的加法定理将所有圆柱散射体的展开中心移到同一个展开中心，最后可以得到一组连结整个散射系统的入射电磁场系数及散射电磁场系数的线性方程组，将该组线性方程配合电磁场在散射体边界的连续条件，便可分别求出圆柱阵列中各个圆柱体的内部电磁场与外部散射场，再利用线性叠加原理即可求得整个圆柱系统的全域电磁场分布。

The result shows that: The variation rhythm of the sensitivity index changed unanimously for Jensen,Blank and Stewart water production functions of spring wheat in Liangzhou city,the volume is small in the former stage,then become large at the middle stage,and less at the last stage. Jensen and Stewart water production functions are better of spring wheat in Gulang County in 1987-1989. The Variation rhythm of water deficiency sensitive index is unanimous: the volume are small at first,then large at middle,and diminish at last. The Variation rhythm of water deficiency sensitive index is unanimous in Jensen,Blank and Minhas of flax in Liangzhou county in 1987-1989. The water deficiency sensitive index in Gulang district in 1987-1989 models bad,are too many minus. 3 Establishing the non-linear model to definitive the irrigation quota and dimension of single crop,according the three prototype Precipitation,allocating the limited water optimally according to full water supply,95 percent,75 percent and 50 percent. Economy benefit is the biggest aim function,so getting three groups for irrigation quota,irrigation dimension and benefit,the biggest benefit is the most optimal result.

结果表明：1985-1986 年凉州春小麦Jensen 模型、Bl(来源：10a1ABC论文网www.abclunwen.com)ank 模型和Stewart 模型的敏感指数变化规律接近一致，在前期较小，中期增大，最后再减小。1987-1989 年古浪春小麦水分生产函数以Jensen 模型和Stewart 模型拟合较好，其敏感指数变化规律比较一致，敏感指标值前期较小，中期增大，后期又减小。1983-1985 年凉州亚麻水分生产函数以Jensen 模型、Blank 模型和Minhas 模型敏感指标值变化规律比较一致：先减小，后增大，最后再减小。1987-1989 古浪亚麻敏感指数出现负值较多，模型拟合较差。3 建立单作物种植条件下灌溉定额与灌溉面积的确定的非线性规划模型，将有限的水量按照充分供水，95%、75%和50%供水来分配水资源，以经济效益最大为目标函数，得出三组灌区灌溉面积和效益结果，其中以效益最大为最优解。

A rather poorer and harder way of life will not defeat them so long as it is not harder and poorer in spirit, so long as it still refuses to reject 'Englishness'- for so many centuries the secret of the islanders' oddity and irrationality, their many weaknesses, their creative strength.

再贫困、再冷酷一些的生活也不能让英国人低头——只要他们在精神上不是更冷酷、更贫困，只要他们依然拒绝抛弃英国人特性——这就是千百年来这些岛国居民的奇特气质和非理性特点以及他们的许多弱点和创造力的奥秘所在。

Use the characteristic of the flameout reboiler, after boil the fresh soup. you can even use it as a boiler which is no need energy sources.

利用熄火再煮锅离开火源可以再沸腾的特点，烧开一锅靓汤后，你甚至可以把它当成可以不用能源的火锅来使用。

Furthermore, in order to guarantee no remained extreme score exists, the final scores are then corrected by the Geometric Average Method.

最后，再利用几何平均法来汇总厂商分数，以确保在一致性条件的要求下，再一次修正可能残留的偏激给分。

Having been thus harass'd in my Thoughts, my old Pilot, to whom I communicated every thing, press'd me earnestly not to go by Sea, but either to go by Land to the Groyne, and cross over the Bay of Biscay to Rochell, from whence it was but an easy and safe Journey by Land to Paris, and so to Calais and Dover; or to go up to Madrid, and so all the Way by Land thro' France.

我为这事心里烦透了，就去与老船长商量。他坚决反对我走海路，而劝我最好走陆路到拉科鲁尼亚，渡过比斯开湾到罗谢尔，再从罗谢尔走陆路到巴黎，既安全又舒适，然后再从巴黎到加来和多佛尔；或先到马德里，然后由陆路穿过法国。

"我仍然爱你，如果我手不能再动，目不能再视，此生以何用来装扮你。"

But they would suffer no resurrection, and I was forced to lie till their malignant master pleased to deliver me: then, hatless and trembling with wrath, I ordered the miscreants to let me out--on their peril to keep me one minute longer-with several incoherent threats of retaliation that, in their indefinite depth of virulency, smacked of King Lear.

但是它们也不容我再起来，我就不得不躺着等它们的恶毒的主人高兴在什么时候来解救我。我帽子也丢了，气得直抖。我命令这些土匪放我出去——再多留我一分钟，就要让他们遭殃——我说了好多不连贯的、恐吓的、要报复的话，措词之恶毒，颇有李尔王之风。

In answering this question, we first look to balance the domestic hackers can get hold of technologies that can invade other computers, do not add up to more than 10,000 people, to remove half of a bad thing to do, and then remove half of the specialized enterprises and large site, and then remove half of the Honker招安done, it is nearly a thousand people left then, there are one billion people, ah, the probability of being black to five million in the lottery than do not go to high.

在回答这个问题之前，我们先来算一下，国内能掌握黑客技术的，能入侵别人计算机的，加起来不会超过一万人，去掉一半不干坏事的，再去掉一半专攻企业和大网站的，再去掉一半被招安做红客的，也就剩下那么将近一千人，全国有10亿网民啊，被黑到的几率比中500万彩票高不到哪去。

This study deals with the prices of American option on dividend-paying. Because American call option can early exercise, in my master thesis, with Black-Scholes Option Pricing Model, I design integral representation to obtain the optimum early exercise boundary, this can evaluate the price of American call option on dividend-paying assets and compare with Europe call option.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
