Lastly, the ruin probability of the bidimensional perturbed risk model are studied, whose upper bound of Lundberg-type within infinit-time is obtained and discussed for the case of light-tailed using the martingale technique, the conclusion is gotten that the strength of the dependent of B strongly impact the upper bound can be achieved.

第四章主要研究了带有扰动项的二维风险模型的破产概率，应用鞅论的技巧，在轻尾条件下，求出Lundberg-type在无限时间内的破产概率的上界；并对破产概率的上界进行讨论，获得的相关性的强弱影响着破产概率可达到的上界。

As I sit at my window this summer afternoon, hawks are circling about my clearing; the tantivy of wild pigeons, flying by two and threes athwart my view, or perching restless on the white pine boughs behind my house, gives a voice to the air; a fish hawk dimples the glassy surface of the pond and brings up a fish; a mink steals out of the marsh before my door and seizes a frog by the shore; the sedge is bending under the weight of the reed-birds flitting hither and thither; and for the last half-hour I have heard the rattle of railroad cars, now dying away and then reviving like the beat of a partridge, conveying travellers from Boston to the country.

在这一个夏天的下午，当我坐在窗口，鹰在我的林中空地盘旋，野鸽子在疾飞，三三两两地飞入我的眼帘，或者不安地栖息在我屋后的白皮松枝头，向着天空发出一个呼声；一只鱼鹰在水面上啄出一个酒涡，便叼走了一尾鱼；一只水貂偷偷地爬出了我门前的沼泽，在岸边捉到了一只青蛙；芦苇鸟在这里那里掠过，隰地莎草在它们的重压下弯倒；一连半小时，我听到铁路车辆的轧轧之声，一忽儿轻下去了，一忽儿又响起来了，像鹧鸪在扑翅膀，把旅客从波士顿装运到这乡间来。

2The speed of creating random series used irrational fraction arithmetic was faster than that of multiplicative congruence arithmetic. The correlative value of random series almost was zero.(3) Regarding not harm the images quality as the premise, the speed of FM screening was heightened.

主要结论：利用所建立的条件半色调函数进行图像加网，操作简单、控制精确，使发生阶调不连续处的密度差平均减少到0.01275，明显改善了调幅加网印品的质量；(2)无理数取尾法产生随机数的速度快，数列间几乎没有相关性；(3)在不损失图像质量的前提下，提高了调频加网的输出速度。

It was grand though, milling through the traffic, our faces all smudged with rouge and the wine gurgling like a sewer inside us, especially when we swung into the Rue Laffitte which is just wide enough to frame the little temple at the end of the street and above it the Sacré Cur, a kind of exotic jumble of architecture, a lucid French idea that gouges right through your drunkenness and leaves you swimming helplessly in the past, in a fluid dream that makes you wide awake and yet doesn't jar your nerves.

这条街的宽度恰好能容纳街尾那所小殿堂，上面是耶稣圣心，一座有外国情调、乱七八糟的建筑，这也是穿越你的醉酒状态、丢下你无助地在过去的日子里游泳的清晰明白的法国观念，这就是叫你在完全清醒而又不刺激神经的飘忽不定的梦幻中游泳。

Leastsquare method and Lagrange's interpolation formula see their applicationsfor fitting fore-and-aft lines-whose aim is to calculate the intersection point ofequivalent inclined waterline-and differences. In order to replace theinconvenient alternate conduct of drawing and calculating, improvement hasbeen introduced into the paper which means all work can be done bycomputer. Capacity calculation cannot be done without boundary layer build-up. Fit every area curve and area moment curve is necessary because ofinterpolation.

在第二章中，给出了B样条函数的数学表达形式，推导了B样条曲线下所围面积、面积矩公式；讨论了最小二乘法和拉格朗日插值法的数学形式，并在拟合船体型线上给出首、尾轮廓线的具体实例，对比不同方法进行拟合的差异，其目的是为了求得与等体积倾斜水线的交点；而水线的确定改变了以往人工作图与计算交替进行的不足，尝试用计算机完全代替人工作图，以求有所改进；在舱容计算中，在至少包括舱室前、后壁的范围内拟合横剖面积、面积矩曲线，插值求得任一纵向位置处的剖面，以解决舱室边界条件。

Analyzed on the tunnels that used EPB method in different soils, the more logical three-dimensional finite element model is based, which can reality represented the soil transfiguration. 3 Due to the engineering example, a 3D FEM simulation model was founded. The model was used to study the rules of soil deformation and surface settlement during shield tunneling. 4 The characteristics of loess include the module, conglutination force and inner friction angle of the loess, affected the soil deformation. 5 The influence factors to the surface settlements such as the depth of soil, the outer diameter of the shield tunnel, the released stress at the cutting face, the fill ratio of the shield tail void, pouring-slurry press, thrusts and lengths of shield and digging steps were studied using the FEM method. References is brought forward in the loess areas of Xi'an was proposed.

通过对不同土质条件下盾构法进行地铁隧道施工的有限元分析，全面反映盾构推进对土体变形的影响情况； 3根据有关勘测资料，建立合理的盾构法施工三维非线性有限元模型，对盾构法施工引起的地层变位和地表位移情况进行计算，分析了盾构施工引起的地层变形规律和地面沉降规律； 4研究了黄土特性(地基模量、粘聚力和内摩擦角)对盾构法施工中土体变形的影响； 5利用三维有限元对盾构施工过程中影响地面沉降的因素(覆土厚度、隧道外径、开挖面压力变化量、注浆压力、盾尾空隙填充率、开挖步长、盾构机的长度和推进力等)进行研究，为今后西安地区地铁的建设提供参考。

This "pair" is easy to tell from other warblers by combination of greyish crown, green upperparts, narrow and very white wing bars, rather white supercilium and rather clean white underparts, pink legs, more skulking habits and frequently-given whistled "tsUUI" notes which to my ear sound very like the call of Daurian Redstart.

这两种柳莺可以和其他柳莺很容易区别，透过它们灰色的冠，绿色的体上，很细又很白的翼带，还算白的眉线，还算乾净、白色的体下，粉红色的脚，喜爱躲藏的习性，以及经常听到，且对我来说很像黄尾鸲叫声的「tsUUI」声音等特徵。

"It is naturally greenish brown or gray, but its colour varies. Selective breed ing has produced more than 125 breed s, including the veiltail, with a three-lobed, flowing tail, and the common, pet-shop comet."

野生状态下，体绿褐或灰色，变异甚多，几个世纪以来，人们选择和培育不正常的个体，已经育成125个以上的金鱼品种，包括常见的具三叶拂尾的纱翅、戴绒帽的狮子头以及眼睛突出且向上的望天。

Orienteering tour guided by our staff and architectural students was arranged and participants were able to visit the centre, which was formerly the Shek Kip Mei Industrial Building, and hence learn more about building revitalisation in Hong Kong.

在导师及建筑系学生的带领下，家长及小朋友以定向游的方式游览这幢前身为石硖尾工厂大厦的特色建筑，藉以探讨香港的建筑活化工作。

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。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
