Above all this scenery of perfect human life, rose dome and bell-tower, burning with white alabaster and gold: beyond dome and bell-tower the slopes of mighty hills, hoary with olive; far in the north, above a purple sea of peaks of solemn Apennine(5), the clear, sharp- cloven Carrara mountains(6) sent up their steadfast flames of marble summit into amber sky; the great sea itself, scorching with expanse of light, stretching from their feet to the Gorgonian isles(7); and over all these, ever present, near or far--seen through the leaves of vine, or imaged with all its march of clouds in the Arno's stream,(8) or set with its depth of blue close against the golden hair and burning cheek of lady and knight,-- that untroubled and sacred sky, which was to all men, in those days of innocent faith, indeed the unquestioned abode of spirits, as the earth was of men; and which opened straight through its gates of cloud and veils of dew into the awfulness of the eternal world; a heaven in which every cloud that passed was literally the chariot of an angel and every ray of its Evening and Morning streamed from the throne of God.

在这一片人世间完美无缺的景色之上，高耸着发出白雪花石膏和黄金的辉煌光芒的圆拱屋顶和钟楼，在拱顶和钟楼的后面是雄伟的山脉，山上长满了灰色的油橄榄树，遥远的北方，在威严的亚平宁山脉紫色的群峰之上，轮廓分明的卡拉拉山把永恒不变的火焰似的大理石山顶插入琥珀色的天空，光芒夺目的浩瀚大海从山脚下一直延伸到戈尔高尼群岛，而在这一切之上，无论是透过葡萄叶丛所见到的，还是阿尔诺河上伴着飘忽的云影所反映出来的，还是同贵妇人和骑士的金色头发和红润面颊相映衬的，是一片蔚蓝的天空，无远弗届，无时不在，宁静而庄严。在那信仰单纯的年月里，对所有的人来说，那苍天无容置疑地是神仙的住所，就象地球是人的住所一样。穿过云端的大门，透过露珠的纱幕，一直通向令人敬畏的永恒世界--那就是天国，在那儿朵朵飘过的云彩实际上都是天使的战车，晨曦和晚霞的每缕光芒都来自上帝的宝座。

This dissertation investigates the construction of pseudo-random sequences (pseudo-random numbers) from elliptic curves and mainly analyzes their cryptographic properties by using exponential sums over rational points along elliptic curves. The main results are as follows:(1) The uniform distribution of the elliptic curve linear congruential generator is discussed and the lower bound of its nonlinear complexity is given.(2) Two large families of binary sequences are constructed from elliptic curves. The well distribution measure and the correlation measure of order k of the resulting sequences are studied. The results indicate that they are "good" binary sequences which give a positive answer to a conjecture proposed by Goubin et al.(3) A kind of binary sequences from an elliptic curve and its twisted curves over a prime field F_p. The length of the sequences is 4p. The "1" and "0" occur almost the same times. The linear complexity is at least one-fourth the period.(4) The exponential sums over rational points along elliptic curves over ring Z_ are estimated and are used to estimate the well distribution measure and the correlation measure of order k of a family of binary sequences from elliptic curves over ring Z_.(5) The correlation of the elliptic curve power number generator is given. It is proved that the sequences produced by the elliptic curve quadratic generator are asymptotically uniformly distributed.(6) The uniform distribution of the elliptic curve subset sum generator is considered.(7) We apply the linear feedback shift register over elliptic curves to produce sequences with long periods. The distribution and the linear complexity of the resulting sequences are also considered.

A noble place; inside as well as out, a noble place--a house in which you incontinently lost yourself if ever you were so rash as to go about it alone; a house in which no one room had any sympathy with another, every chamber running off at a tangent into an inner chamber, and through that down some narrow staircase leading to a door which, in its turn, led back into that very part of the house from which you thought yourself the furthest; a house that could never have been planned by any mortal architect, but must have been the handiwork of that good old builder--Time, who, adding a room one year, and knocking down a room another year, toppling down a chimney coeval with the Plantagenets, and setting up one in the style of the Tudors; shaking down a bit of Saxon wall there,and allowing a Norman arch to stand here; throwing in a row of high narrow windows in the reign of Queen Anne, and joining on a dining-room after the fashion of the time of Hanoverian George I.

一个高贵的地方，里里外外，全然是个高贵的地方——好一个府邸，如果你竟鲁莽得独自东闯西跑，你立刻就会茫然迷失；好一个府邸，其中没有一个房间同另一个房间有什么和谐一致之处，每个房间都逸出常轨，突入一个内室，再经由内室下到某一个楼梯上，楼梯通向一个门，门又导引你回到了老地方，你还自以为这是府邸中离此最远的部分哩；好一个府邸，任何人间的建筑师都设计不出来的，必定是善良古老的建设者——时间——亲手营造的。时间在这一年增加了一个房间，在另一年又弄塌了一个房间；一会儿推倒一个与金雀花王朝同时代的烟囱，另外垒起一个都锋王朝风格的烟囱；那儿推倒一点儿撒克逊时代的墙垣，这儿又容许建立一道诺曼拱门；既把安女王统治时期流行的一排又高又狭的窗子硬装了上去，又按照乔治一世时代的时髦样式修建了餐室，同一个自从威廉征服英国以来兀立至今的斋堂相毗连。

An assumed Gaussian tail is addedonto the HO distribution. The calculations for〓 of the protron-rich isotones 〓〓 and 〓 and for 〓 the neutron-rich isotopes 〓were finished by theGlauber Model along with the modified density distrution. The calculated resultsshow that d values of these nuclei along with the modified density distribution arelower than the calculated ones along with the only HO density distribution.

为减小Glauber模型计算的反应截面与实验值的差别，本论文还对Glauber模型的输入密度形式进行了修改，在原单-HO分布基础上加一个高斯分布的尾巴，并对丰质子的同中子素核〓及〓与〓靶以及〓和丰中子的C同位素核〓与〓靶的反应截面重新进行了计算，结果显示在中能区的计算值比原来单一密度分布的计算结构有明显改善。

The similarity between 71.8% of 41 detected sequences and published clone sequences were less than 97%, which represented a new community and 15.3% of the clone sequences which identitied with GenBank clone sequences were under 85%, which may represent some new families or suborders.

The results show that in the applied load range of 10250 N, the mass loss rate of coated AZ91D alloy can be identified to three stages, which are related with whether the coating is worn out. Abrasion is the main mechanism for the coated alloy. The friction coefficient of the coated alloy during sliding wear appears oscillation before it reaches a constant value, which is close to the μ value of the matrix alloy. The mass loss rate of coated alloy increases slightly with increasing applied load when the applied load is more than 150 N because of high plastic deformation accommodation on the matrix alloy surface.

结果表明：根据载荷大小，涂层处理后AZ91D镁合金的磨损行为明显分为3个阶段，这些阶段同陶瓷层是否磨穿密切相关；微弧氧化涂层AZ91D镁合金的磨损机理主要是磨粒磨损；受表面状况的影响，陶瓷涂层的摩擦因数在 0.20~0.45 间波动；在较高载荷下，涂层被磨穿后，涂层的摩擦因数趋于基体合金的摩擦因数，涂层合金的表面变形能力提高，该阶段质量磨损速率随载荷增加，趋势变得缓慢。

The rationals of anti-angiogenesis are the following: the therapeutic target is tumor endothelial cells which are more genetically stable, more homogeneous, and with lower mutation rate; the anti-angiogenesis drugs can contact endothelial cells directly, with higher potency and lower drug barriers and side effects; the aim of anti-angiogenesis therapy is to block the oxygen and nutrition supply from vessels, instead of killing tumor r ells per se; the aim of anti-angiogenesis is to reduce tumor size instead of eradicate tumor which are different from traditional chemotherapy.

使用抗血管新生疗法根据的理论基础为以肿瘤血管的内皮细胞为治疗药物的攻击标的；肿瘤血管的内皮细胞基因比较稳定、同质性高、而且突变率低；投与的药物可以直接接触内皮细胞，减少投与药物屏障，因此增加有效投与药物的能力及减少药物副作用；以截断供应肿瘤氧气养分的血管为目标：以减小肿瘤的体积大小为目的，与传统化学疗法以根除肿瘤的目标不同。

Those principles even appeared at the Council of Trent, where the ambassadors, theologians, and bishops of France repeatedly championed them, notably when the questions for decision were as to whether episcopal jurisdiction comes immediately from God or through the pope, whether or not the council ought to ask confirmation of its decrees from the sovereign pontiff, etc. Then again, it was in the name of the Liberties of the Gallican Church that a part of the clergy and the Parlementaires opposed the publication of that same council; and the crown decided to detach from it and publish what seemed good, in the form of ordinances emanating from the royal authority.

这些原则甚至出现在安理会的遄达，那里的大使，神学家，和主教的法国一再倡导，尤其是当问题的决定是否是主教管辖范围内立即从上帝或通过教皇，不管安理会应该要求确认其法令，从教皇的主权，等等再说，它的名字自由的高卢圣教会的一部分，神职人员和Parlementaires反对出版同安理会和冠决定分离，并从发布似乎很好的形式，法令来自王室的权威。
