He was perusing the bulletins of the grand army, those heroic strophes penned on the field of battle; there, at intervals, he beheld his father's name, always the name of the Emperor; the whole of that great Empire presented itself to him; he felt a flood swelling and rising within him; it seemed to him at moments that his father passed close to him like a breath, and whispered in his ear; he gradually got into a singular state; he thought that he heard drums, cannon, trumpets, the measured tread of battalions, the dull and distant gallop of the cavalry; from time to time, his eyes were raised heavenward, and gazed upon the colossal constellations as they gleamed in the measureless depths of space, then they fell upon his book once more, and there they beheld other colossal things moving confusedly.

有天晚上，他独自待在屋顶下的那间卧室里。他燃起了烛，推开了窗，两肘倚在窗前的桌子上，从事阅读。

According to the selected electric actuator determine the electrical parameters Because of different electric actuator manufacturers have different electrical parameters, design selection Butterfly Valves generally takes time to determine their electrical parameters, mainly electric power, rated current, secondary voltage control loop, are often negligent in this regard, the results of control system and the electric actuator parameter does not match the space-time caused by the work of opening trip, fuses, fuse, thermal overload relay protection is like a take-off and other failures.

根据所选电动执行器确定电气参数因不同电动执行器厂家的电气参数有所差别，所以设计选型时一般都需确定其电气参数，主要有电机功率、额定电流、二次控制回路电压等，往往在这方面的疏忽，结果控制系统与电动执行器参数不匹配造成工作时空开跳闸、保险丝熔断、热过载继电器保护起跳等故障现像。

For Shen Jianhua, photograph is not restricted in its yoke of space-time reference marks, of images of a private diary, it takes at his place very an other dimension: It is a true setting in scene of its dreams, its phantasms, and its desires, suggesting at the same time the sensuality, the strange one, the unknown of the subconscious.

沈见华用摄影实现绘画的表达和艺术的愿望，给摄影一个另外的生机，使它可以不再是记录的，而和绘画一样，是思想、心灵、感情及性情的自由表现。脱出了普通摄影的类型化框框，而使日光下的事物都可以是抽象绘画的感觉，并用非常空静的画面，洗练地表达事物的本性，获得了个性化的风格。

The boundary shape and length of fire zone are growth with time, which determine the fire HRR is variational with time and space distribution.

火场边界形状长度和火场面积随时间而变化发展，决定了火灾释热率在时间和空间分布上都是变化的函数，火灾HRR不同于稳态火和T〓火。

The Quasi-Normal oscillation shows the character of background space-time changing with time.

我们研究了无质量标量场在随时间变化的Schwarzschild黑洞背景下的扰动行为。

By the analyses on the existing detector generating algorithms, we achieved the improvement of the linear time detector generating algorithm, which was widely used at present. The efficiency of the linear algorithm was improved by eliminating the reluctant detectors, and at the same time the improved algorithm was ensured to cover the nonself space as much as possible.

在分析已有的检测器生成算法的基础上，改进了目前使用最多的线性检测器生成算法，通过消除冗余的检测器提高了线性检测器生成算法的效率，同时还保证了改进后的算法能够尽可能多地覆盖&非我&空间。

Finally, we establish rational spectral formation of discrete with regard to time and space, and gained the error estimate in the finite-time in the abstract.

最后，我们构造了同时关于时间空间方向离散的谱格式，并从理论上建立了在有限时间上的全离散格式近似解的误差估计。

According to the current high real time peculiarity and high precision demands of beacon beam processing subsystem of space optical communication and the requirements of our project, the method that uses digital signal processor to solve the image position error signal extraction of beacon beam is proposed in this dissertation. It have the following advantages: the small system volume, the slight weight, the small power, the high real time peculiarity and the high precision and so on.

根据目前空间光通信对信标光处理子系统提出的高实时性和高精度性的要求以及课题的需要，本论文提出用数字信号处理芯片DSP来解决空间光通信中信标光的像面位置误差信号提取的问题，其优点就是系统体积小、重量轻、功耗低、实时性高、精度高等。

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。
