查询词典 raft

In this paper,the raft is approximated by a thin plate with regular shape at first.Then the floating raft system is divided into several subsystems,such as plate raft,elastic foundation,etc,which are respectively modeled by four-parameter net method.After that,dynamic absorber and active absorber are put into a uniform frame to obtain the model of plate raft subsystem coupling with them.At last,according to the force and velocity relationship among each subsystem\'s interfaces,the entire plate floating raft system is modeled by subsystem structural admittance synthesis method.As the main structure of floating raft system is elastic,it is inevitably to study the optimization of actuators\' mounting positions before designing control law.In this paper,two new criterions are proposed for it.

本文首先将浮筏的中间筏架用一个规则形状的薄板近似；然后再将浮筏系统分解成若干个子系统，如板式筏架子系统、弹性基础子系统等，运用四端参数网络建立了它们的动力学传递方程，传递特性由导纳矩阵描述；接着，将动力吸振器和主动吸振器的(来源：ABC90论文00网www.abclunwen.com)分析统一于一个框架内，获得了与吸振器耦合的板式筏架子系统的动力学传递特性；最后，根据各子系统在各界面上的作用力和速度的相互关系，通过子系统结构导纳综合方法获得了整个板式浮筏系统的动力学传递方程，并在此基础上获得了系统的力传递函数模型。

At length I spy'd a little Cove on the right Shore of the Creek, to which with great Pain and Difficulty I guided my Raft, and at last got so near, as that, reaching Ground with my Oar, I could thrust her directly in, but here I had like to have dipt all my Cargo in the Sea again; for that Shore lying pretty steep, that is to say sloping, there was no Place to land, but where one End of my Float, if it run on Shore, would lie so high, and the other sink lower as before, that it would endanger my Cargo again: All that I could do, was to wait 'till the Tide was at highest, keeping the Raft with my Oar like an Anchor to hold the Side of it fast to the Shore, near a flat Piece of Ground, which I expected the Water would flow over; and so it did: As soon as I found Water enough, for my Raft drew about a Foot of Water, I thrust her on upon that flat Piece of Ground, and there fasten'd or mor'd her by sticking my two broken Oars into the Ground; one on one Side near one End, and one on the other Side near the other End; and thus I lay 'till the Water ebb'd away, and left my Raft and all my Cargo safe on Shore.

最后，我终于在小河的右岸发现一个小湾。我费尽艰辛，好不容易把木排驶到最浅的地方。我用桨抵住河底，尽力把木排撑进去。可是，在这里，我几乎又一次险些把货物全都倒翻在水里。这一带河岸又陡又直，找不到可以登岸的地方。如果木排一头搁浅在岸上，另一头必定会像前次那样向下倾斜，结果货物又有滑向水里的危险。这时，我只好用桨作锚，把木排一边固定在一片靠近河岸的平坦的沙滩上，以等待潮水涨高，漫过沙滩再说。后来，潮水果然继续上涨，漫上沙滩，等水涨得够高了，我就把木排撑过去，因为木排吃水有一尺多深。到了那儿，我用两支断桨插入沙滩里，前后各一支，把木排停泊好，单等潮水退去，就可把木排和货物品平安安地留在岸上了。

Besides the dinosaur raft, there have been race car rafts, a Snoopy raft and a Dumbo raft.

除了恐龙木筏之外，也有赛车木筏、史奴比木筏及蠢蛋木筏。

Raft foundation can be analyzed by this program. And interaction of raft foundation in different plane shape and different thickness with soil that simulated by Winker or two-parameter soil model and high-rise building superstructure can be computed and analyzed. The program provides a new and effective analysis tool for the practice of high-rise building raft foundation engineering.

针对上述各种计算理论及分析内容，自行编制了相应的面向对象计算程序PIASRFS-2007，程序用C++语言在VC++平台中编制，采用该程序可以采用无网格法对筏板基础进行计算分析，并能对不同平面形状、不同厚度的筏板基础与Winkler、双参数弹性地基及高层建筑的不同上部结构进行三者的共同作用计算分析，该程序为高层建筑筏板基础工程实践提供了一种新型有效的分析手段。

In spite of this, the preparation of thiol-end functionalized PMMA was achieved by introducing a short block of polystyrene after the RAFT polymerization of MMA.Third, RAFT technique was applied to design and synthesize some well-defined poymers. Five monomers, lauryl methacrylate,(N,N-dimethylamino)ethyl methacrylate, poly methyl ether methacrylate, 4-(4\'-cyanobiphenyl-4-yloxy) butyl methacrylate and 2-ethyl methacrylate were chosen to RAFT homopolymerization or copolymerizations mediated by cumyl dithiobenzoate.

RAFT方法在具有特定结构聚合物的设计与合成上的应用，在机理研究的基础上，本论文选择五种不同结构的甲基丙烯酸酯类单体：lauryl methacrylate，(N，N-dimethylamino)ethyl methacrylate，polymethyl ether methacrylate，4-(4'-cyanobiphenyl-4-yloxy)butyl methacrylate和2-ethyl methacrylate，用CDB调控RAFT聚合的方法设计合成了一些特定结构的聚合物，详细而深入地研究了它们的均聚、共聚动力学，发现了双硫酯并非在聚合反应初期就全部转化，而是随着反应进行逐步消耗，这与理想的活性聚合体系有很大差别。

To get more insight into the mechanism and kinetics of the RAFT process,it would be helpful to build a small molecular model reaction mimicking the RAFT process but free of a chain-propagation event. We hereby propose a model cross reaction between dithioester and alkoxyamine as a probe of the RAFT process,in which the alkoxyamine plays the role of the radical source.The generating rate of the transient alkyl radical and the nitroxyl radical can be described by the law of persistent radical effect.Thus,the advantage of the model cross reaction is that it affords a radical concentration determined by the known equation of the persistent radical effect.

为了更深入的理解RAFT聚合过程，我们构建了一个模型反应：即由烷氧基胺与双硫酯进行交换反应，烷氧基胺均裂产生的烷基自由基将会向双硫酯进行链转移，双硫酯的引入对纯烷氧基胺分解动力学造成的影响可以提供RAFT过程的许多信息。

The results show that more modalities can be excited from asymmetric system and that there is little difference between the power flow spectra of rigid raft system and flexible raft system in middle and low bands of frequency, but there is considerable difference at high frequency.

研究结果表明，非对称系统能激励出更多的模态；在中低频段弹性浮筏系统和刚性浮筏系统的功率谱没有很大的区别，但是在高频段差别则很明显，浮筏的弹性模态起着主要作用；减小隔振器的刚度并适当增加隔振器阻尼不仅可以降低传递到基础的功率谱，同时还可以抑制共振减小冲击。

Jim said that he hoped that they would not stay away from the raft a long time because he was tired of having to be tied up with ropes and kept in the tent on the raft all day.

吉姆说，他希望他们别离开筏子太久，因为他对用绳子捆住他，让他整天呆在筏子上的窝棚里感到又累又烦了。
