The formation mechanism of the absolute instability and gyrotron backward wave oscillations is analyzed, and the methods to suppress the parasitical modes are discussed.The nonlinear theory model of gyro-TWT is consummated by considering the influence of tapered magnetic field and waveguide radius, electron velocity spread, and waveguide loss on electron beam-wave interaction. The large-signal characteristic of gyro-TWT, such as launching loss and absolute instability, are also analyzed in detail. This work establishes the foundation for the development of a gyro-TWT amplifier.

重点研究了两段损耗波导结构和损耗陶瓷结构回旋行波管中的电子注-波互作用，分析了绝对不稳定性和回旋返波振荡的形成机制和抑制寄生模式的方法；完善了回旋行波管的非线性理论模型，并考虑了磁场和波导半径渐变、速度零散、波导损耗等因素对注-波互作用的影响；详细分析了发射损耗、相位稳定性等回旋行波管的大信号特征，为回旋行波管放大器的研制奠定了基础。

I swear by Apollo the physician, by Aesculapius, Hygeia, and Panacea - and I call as my witnesses all gods and goddesses - that I will keep the following oath according to my ability and judgement

我谨此向阿波罗医师、向埃斯科拉庇俄斯（罗马神话里医药与康复之神——译者注）、海吉尔（司健康希腊女神—译者注）和潘纳西尔起誓，我恳请所有男女众神作证—我将按照我的能力和判断遵守以下誓言

There is an edited edition of his letters from his trip round the world on HMS Beagle（注2）, an effort to connect his life with that of Abraham Lincoln (who was born on the same day, February 12th 1809), an attempt (surely redundant for supporters and futile for opponents) to explain "Why Evolution is True", and even a collection of essays on Alfred Russel Wallace（注3）, who came up with the idea of natural selection at the same time as Darwin, and bounced him into publishing before he was really ready.

有一本书对达尔文乘坐贝格尔号环游世界期间所写信件加以修订，另一本费尽心思将他与同于1809年2月12日出生的亚伯拉罕。林肯牵扯在一起，还有试图解释"进化论为什么不可摇撼"（当然，这对支持者略显多余；对反对者则是徒劳无功），甚至有一本关于阿尔弗雷德。罗素。华莱士的随笔集也随之问世（华莱士和达尔文同时提出了自然选择的理论，正因读到华莱士的论文，达尔文的《物种起源》才未臻成熟就付诸出版）。

Gas composition, gas carbon isotope and high molecular hydrocarbon released from organic inclusions in the same aliquot sample can be analyzed using the new crushing device.

应用此方法对江苏句容地区有机包裹体的来源及充注期次进行了探讨，包裹体成分特征表明句容地区经历了多期油气的充注。

Ampoules,I ampoule is given each time by intramuscular or slow intravenous injection, 2 3 times daily .

针剂，每次1瓶，1日2—3次，股注或缓慢静注。

"You know the world is going crazy when the best rapper is a white guy, the best golfer is a black guy, the tallest guy in the NBA is Chinese, the Swiss hold the America's Cup, France is accusing the U.S. of arrogance, Germany doesn't want to go to war, and the three most powerful men in America are named 'Bush','Dick', and 'Colon.' Need I say more?"

你知道这个世界有多疯狂吗，最好的饶舌歌手是白人，最好的高尔夫选手是黑人，NBA身高最高的选手是中国人，瑞士人卫冕美洲杯帆船赛事，法国指责美国自大，德国不参战，美国最有权的三个人分别叫&布什&（译者注：英文&杂草&的意思）、&迪克&（译者注：美国俚语里&男性生殖器&的意思）、&科隆&（译者注：&结肠&的意思），还用我就更多例子吗？

In Limit and even No-Limit games, you'll see a lot of "Raise, Call, Call, and Call" going on.

在限注甚至不限注游戏中，你总能碰到许多&加注，跟注&的情形。

Three individuals, I have a bargaining chip has been leading blind and growing, supra note, I am more and more steady, did not give our opponents any chance, finally a card to vote blind exhausted opponents only 800 chips, but ALLIN.

3个人时，我筹码一直领先，盲注和前注越来越大，我越来越稳，没给对手任何机会，最后一把牌对手盲注投完后只有800筹码，不得不ALLIN。

It was clear that the Cherenkov radiation is result of the coupling between the slow TM mode propagated along the waveguide and the negative-energy space-charge mode propagated along the beam, and the coupling strength is proportional to the beam density.

分析结果表明：切伦科夫辐射是由沿介质同轴波导传播的慢波与沿薄环形相对论电子注传播的负能空间电荷波耦合所致，且其耦合强度与电子注的密度成正比；输出频率和波增长率随着填充等离子体密度的增大而提高；保持一定的输出频率，增大电子注的束流可得到高的微波输出功率。

Seeing North Korea less as Upper Volta with nukes and more as Branch Davidians with nukes may not seem all that comforting, especially if one remembers how the Waco siege of 1993 ended.

不将朝鲜看作拥有核武器的上沃尔特（Upper Volta，现名布基纳法索，西非内陆国，借指区域小国--译者注），而更多地将其看作拥有核武器的大卫教派（Branch Davidians，美国基督教极端教派--译者注），或许并不那么令人放心，尤其是如果人们记得1993年围攻韦科事件是如何结束的话（1993年美国联邦调查局围攻德克萨斯州韦科镇大卫教的庄园，最后庄园起火，造成86名信徒丧生--译者注）。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
