Eyes he looked at the total distance, and the distance is only a piece of wilderness, like the helpless baldhead head.

One would approach at first warily through the shrub oaks, running over the snow-crust by fits and starts like a leaf blown by the wind, now a few paces this way, with wonderful speed and waste of energy, making inconceivable haste with his "trotters," as if it were for a wager,and now as many paces that way, but never getting on more than half a rod at a time; and then suddenly pausing with a ludicrous expression and a gratuitous somerset, as if all the eyes in the universe were eyed on him —— for all the motions of a squirrel, even in the most solitary recesses of the forest, imply spectators as much as those of a dancing girl —— wasting more time in delay and circumspection than would have sufficed to walk the whole distance—— I never saw one walk —— and then suddenly, before you could say Jack Robinson, he would be in the top of a young pitch pine, winding up his clock and chiding all imaginary spectators, soliloquizing and talking to all the universe at the same time —— for no reason that I could ever detect, or he himself was aware of, I suspect.

有一只赤松鼠开始谨慎地穿过矮橡树丛，跑跑停停地在雪地奔驰，像一张叶子给风的溜溜地吹了过来；一忽儿它向这个方向跑了几步，速度惊人，精力也消耗得过了份，它用"跑步"的姿态急跑，快得不可想象，似乎它是来作孤注一掷的，一忽儿它向那个方向也跑那么几步，但每一次总不超出半杆之遥；于是突然间做了一个滑稽的表情停了步，无缘无故地翻一个觔斗，仿佛全宇宙的眼睛都在看着它，——因为一只松鼠的行动，即使在森林最深最寂寞的地方，也好像舞女一样，似乎总是有观众在场的，——它在拖宕，兜圈子中，浪费了更多的时间，如果直线进行，早毕全程，——我却从没有看见过一只松鼠能泰然步行过，——然后，突然，刹那之间，它已经在一个小苍松的顶上，开足了它的发条，责骂一切假想中的观众，又像是在独白，同时又像是在向全宇宙说话，一我丝毫猜不出这是什么理由，我想，它自己也未必说得出理由来。

In order to obtain symmetry and parallel polarized light, the double Wollaston prism is amended. After getting symmetric polarized light at a big splitting beam angle, an ordinary triangular prism is added so that the symmetric light beam can be divided into parallel light beams. The distance between the triangular prism and the double Wllaston prism is changed so that the distance of the shearing parallel light can be changed.

The main contents are as follows.1 For the state control problem in closed quantum systems, according to the distance between states, the error between states and the average value of an imaginary mechanical quantity, three Lyapunov functions are chosen, respectively. The corresponding control law designs and the convergence analyses are studied. Especially, for the Lyapunov function based on the distance between states, a class of control laws that can solve the problem that an initial state is orthogonal to a goal state is designed. The convergence of the system is analyzed via LaSalle\'s principle and one method to find the largest invariant set of the closed loop system is proposed by linearizing the unitary evolution operator at the corresponding instants.

在这一背景下，本论文在指出研究量子系统控制的必要性、回顾量子系统控制理论和方法的研究现状的基础上，从控制理论的角度研究Lyapunov理论和最优控制理论对于封闭量子系统的应用以及开放系统中的若干问题，主要内容包含以下几个方面。1针对封闭量子系统中的状态控制问题，根据状态间的距离、状态间的偏差、一个虚拟力学量的均值，分别选择三种Lyapunov函数进行相应的控制律设计和收敛性分析。

I was now furnished with Roots and Corn, such as it was, and Water, and leaving my friendly Negroes, I made forward for about Days more without offering to go near the hoar, till I saw the Land run out a great Length into the Sea, at about the Distance of four or five Leagues before me, and the Sea being very calm I kept a large offing to make this Point; at doubling the Point at about two Leagues from the Land, I saw plainly Land on the other Side to Seaward; then I concluded, as it was most certain indeed, that this was the Cape de Verd, and those the Islands, call'd from thence Cape de Verd Islands.

现在，我有了不少杂粮，又有了水，就离别了那些友好的黑人，一口气大约又航行了十一天，中间一次也没有登岸。后来，我看到有一片陆地，长长地突出在海里，离我们的船约十三、四海里。当时风平浪静，我从远处经过这海角；最后，在离岸六海里左右绕过这小岬角后，又发现岬角的另一边海里也有陆地。这时，我已深信不疑，这儿就是佛得角，而对面的那些岛屿即是佛得角群岛。

By the use of Circling cluster and Envlopment theory and flat surface sit-mark transformation theory, the chain wheel tooth equation of roller chain at high speed to match conjugage engagement is deduced.Establishing chain speed equation of roller chain at high speed,based on the analysis of the speed curves between roller chain at high speed and common roller chain,good drive of roller chain at high speed is verificated theoretically.By a example that move distance from transverse vibration between roller chain at high speed and common roller chain is contrasted,the accuracy of those theories that the paper brings up and higher functions of roller chain at high speed is proved.Finally, Establishing conjugage engagement line equation of roller chain at high speed and analyzing the complete engagement zone, the chain wheel tooth curve equation is studied at a higher degree. At the same time,the lack's place of the research result is pointed out.
