Her griddlecakes done to a goldenbrown hue and queen Ann's pudding of delightful creaminess had won golden opinions from all because she had a lucky hand also for lighting a fire, dredge in the fine selfraising flour and always stir in the same direction, then cream the milk and sugar and whisk well the white of eggs though she didn't like the eating part when there were any people that made her shy and often she wondered why you couldn't eat something poetical like violets or roses and they would have a beautifully appointed drawingroom with pictures and engravings and the photograph of grandpapa Giltrap's lovely dog Garryowen that almost talked it was so human and chintz covers for the chairs and that silver toastrack in Clery's summer jumble sales like they have in rich houses.

她那烤成金褐色的薄饼和放有大量美味奶油的安妮女王布丁曾赢得过众人的好评。因为她有一双灵巧的手，不论点火，还是撒上一层加了发酵粉的精白面，不断地朝一个方向搅和，然后搀上牛奶白糖，调成奶油，或是将蛋清搅匀，她样样擅长。不过，她可不喜欢当着人面吃什么，怪害臊的。她常常纳闷为什么不能吃一些像紫罗兰或玫瑰花那样富于诗情的东西！他们还会有一间布置优雅的客厅，装饰着绘画、雕刻以及外祖父吉尔特拉普那只可爱的狗加里欧文的照片。它是那样通人性，几乎能说话了。椅子套着光滑的印花棉布罩子，还有来自克莱利的夏季旧杂货义卖展上的银质烤面包架，就像阔人家拥有的那样。

When used in LAB complex unit with multi-step hydrogenation process,DSH-1 selective hydrogenation catalyst,which contain noble metal Pd,can transmit diolefin s to olefins effectively,and has good activation and selectivity.

The 2-D transfer function of the bistatic SAR is obtained. Azimuth position distortion along range existing in the original alogrithm is corrected by mapping from scene coordinate to azimuth-slant distance coordinate. Bistatic SAR date can still be processed by a mono-static SAR processor. The efficaciousness of the proposed algorithm is verified through point target simulations.

算法通过数值计算得到双基地二维传递函数，通过场景坐标系向方位－斜距平面的映射校正了原算法中存在的沿距离变化的方位位置畸变，进而来用常规单基地SAR成像处理流程实现对双基地SAR回波数据的成像处理，最后通过点目标仿真验证了算法的有效性。

As the maneuverability of the model of 800 t ship with double tail fins didn′t meet the design standard,this article turned the twin skeg of the models into tail-shaft strut,and then made tur-ning tests and Z shape tests.

针对某一采用双尾鳍形式的800 t级排水船在进行自航模试验时出现操纵性能不能满足设计要求的情形，文中将其尾部的双尾鳍改成轴支架，并在某露天操纵性水池中，对改进后的自航模进行了回转和Z形操纵试验，通过对实验结果进行比较发现合理设计轴支架的大小和安装位置能够较好地改善800 t级排水船的操纵性能，并能够满足给定的船舶操纵性能设计要求。

There was on his face an expression of solemn and holy rapture, as if he were revealing to me the mysteries of his religion. I became far more interested in him than in the socks. I looked at him in amazement."My friend," said I,"if you can keep this up, if this is not merely the enthusiasm that comes from novelty, from having a new job, if you can keep up this zeal and excitement day after day, in ten years you will own every sock in the United States." My amazement at his pride and joy in salesmanship will be easily understood by all who read this article. In many shops the customer has to wait for someone to wait upon him. And when finally some clerk does deign to notice you, you are made to feel as if you were interrupting him. Either he is absorbed in profound thought in which he hates to be disturbed or he is skylarking with a girl clerk and you feel like apologizing for thrusting yourself into such intimacy. He displays no interest either in you or in the goods he is paid to sell. Yet possibly that very clerk who is now so apathetic began his career with hope and enthusiasm. The daily grind was too much for him; the novelty wore off; his only pleasures were found outside of working hours. He became a mechanical, not inspired, salesman. After being mechanical, he became incompetent; then he saw younger clerks who had more zest in their work, promoted over him. He became sour. That was the last stage. His usefulness was over. I have observed this melancholy decline in the lives of so many men in so many occupations that I have come to the conclusion that the surest road to failure is to do things mechanically. There are many teachers in schools and colleges who seem duller than the dullest of their pupils; they go through the motions of teaching, but they are as impersonal as a telephone.

他的脸色庄严而虔诚，就像是在向我透露他的信仰中的奥秘似的我对他远远超过了对袜子的兴趣我吃惊地打量着他"我的朋友，"我说，"如果你能这样保持下去，如果这热情并不仅仅缘于新奇，缘于找到份新工作，如果你能日复一日地保持这种热心和激情，不出十年，全美的每一双袜子都将是从你手中卖出去的"我对他推销时的自豪与欣喜所感到的诧异，读者诸君当不难理解在很多店铺，顾客不得不等待有人来招呼当终于有个售货员肯屈尊理你，那样子又让你感觉像是打扰了他他不是陷于讨厌被人搅扰的深思之中，就是和女售货员嬉戏调笑；而你不适时的插入打断了他们的亲昵，为此你感觉好像需要道歉似的他显示出对你和他拿着工资去卖的东西毫无兴趣然而，就是这样一个如此冷漠的售货员，或许当初也是满怀希望和热情开始工作的天天枯燥乏味的苦差事令他不堪忍受，新鲜感磨去了，惟一的乐趣只能在工作之外找到他成了一个机械的没有干劲的售货员机械呆板之后便是笨拙无能随后，看到比他年轻工作热情比他高的售货员得到了提拔，在他之上，他于是变得烦躁刻薄此时便到了他职业生涯的最后阶段他不再有用了我观察到，很多职业中的太多人在人生道路上都有这种可悲的堕落由此我得出结论：机械地应付差事是离失败最近的路大中小学里的许多教师，似乎比他们最最迟钝的学生还要呆滞；他们似乎也搞搞教学，却毫无人的感情，就如同一部电话机

These excellent properties of 9E-BHVC all mentioned above imply that it would be a true two-photon nucleic acid fluorescent probe if it can specially recognize the DNA in complex cellulous environment.So this dissertation has investigated the ability of 9E-BHVC on the cell nucleus imaging detaily.

Chirp scaling algorithm is considered more efficient and widely applicable when the bistatic SAR system is in side-look or small squint angle mode,but in large squint angle case,the errors caused by Taylor expansion are so large that the algorithm could lose its precision.In such a case,an equivalent mono-static SAR range mode which has fewer errors than Taylor expansion with large squint angle is proposed to substitute the range history of bistatic SAR.Then bistatic SAR images with large squint angles are gotten by common Nonlinear CS algorithm.The effectivity of the method is verified by Matlab simulation.

在正侧视或小斜视情况下，CS算法具有较好的聚焦性能和广泛的适用性，但在斜视角较大的情况下，该算法将散焦而不能成像，因而提出了用等效的单基地距离模型来代替双基地距离历史的方法，解决了大斜视角情况下距离模型二阶近似误差较大的问题，并结合单基地非线性CS算法，实现了在大斜视角情况下的基于GPS反射信号的双基地SAR高精度成像，最后通过Matlab仿真进行了验证。
