The characters of linear complexity profile of periodic sequences are investigat- ed. The relation between the continued fraction expansion of rational function and its 1- inear complexity profile is established. The expression of linear complexity profite is gi-~~en and a condition estimating the randomness of a sequence is presented. By the linear complexity profile, the bound of sphere complexity is proposed. A formula to record the number of sequences with given linear complexity profile is presented.

A few years of in the past, chen Yizhou is playing the game that the ball throws in acrobatics all the time, if a website is a ball, he is cast at the same time those who rise is 67 balls, his craft is excellent but also hurry-scurry of hard to avoid, do not have too much time and research of energy with great concentration more among them the secret of a certain ball, have so period of time, he begins to choose, the sphere of many a weak force was abandoned by him, there are two balls only in his hand now, one is the net inside school, one is the cat attacks net.

过去的几年，陈一舟一直玩着杂技中抛球的游戏，假如一个网站是一个球，他同时抛起来的是六七个球，他技艺高超但也难免手忙脚乱，更没有太多的时间和精力潜心研究其中某个球的奥妙，有那么一段时间，他开始选择，一个一个弱势的球体被他抛弃了，现在在他的手中只有两个球，一个是校内网，一个是猫扑网。

The effect of Reynolds number on rudder hydrodynamic performance is also analyzed. Up to the stall angle the computed lift and drag agree well with measurements and other author's calculations, whereas stall angle, lift and drag beyond the stall angle are slightly under-predicted. The solver is used to investigate laminar and turbulent separated flows around a 6: 1 prolate spheroid at high incidence angles and their effects on hydrodynamic forces. The second separation flows are successfully identified in both laminar and turbulent flow simulations.

The whole architecture consists of three parts: in the west is a sector space with its height increasing by degrees; in the middle is a transparent oval-shaped hall of glass (42 meters at the highest and 67 meters at the widest) and a yellow sphere in the center (18 meters in diameter), which symbolize the boundlessness of the universe and the gestation of life; in the east is a four-storied framework, each floor 10-meter high and the highest place rising 49 meters above the ground floor.

The results show that the diffraction patterns for WS2 single phase were observed; the pronounced quantum size effect exists in S-W-S nano clusters, and it enhances the hybridization of different electronic shell obits and formed a closed hollow spherical structure without any dangling bond. In the lubricating process, such a system can maintain its chemical stability and decrease energy dissipation.

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。
