各自地

When we give up all claim to a knowledge of the final end, we shall clearly perceive that just as we cannot invent any flower or seed more truly appropriate to a plant than those it produces, so we cannot imagine any two persons, with all their past in such complete congruity down to the smallest details, with the part they were destined to play.

放弃对最终目的的探求，我们便会清楚地看到，一种植物有一种植物的花朵和种子，我们无法去空想更适合于这种植物的其他花朵和种子。同样，我们也无法想象其他两个有各自经历的人能比拿破仑和亚历山大更合适地、更细致地和更彻底地完成他们天赋的使命。

The main job and contribution of this paper are as follows:Based on narrowband signal processing, we propose a new method for FH signal blind detection and blind parameter estimation. Firstly, compute the cross-correlation function of FH signals from multichannels, then we get the cross power spectral density matrixCSDM Secondly, select the hops of FH signals from the CSDM via processing and analyzing the CSDM, meanwhile reduce the influence coming from noise, fixed frequency signal and other interferences; Lastly, estimating the DOA of every hop and according to the DOA, we can separate the hops, get the number of FH signals and their parameters. Propose a new method for designing the threshold in FH signal detection. This method makes it easy to get the threshold by theoretic computing and it can extremely reduce the interference of non-FH signals.Based on broadband signal processing, we propose a new method for FH signal blind detection and blind parameter estimation. Firstly, get the DOA of the signals by wideband spatial spectrum estimation; secondly, separate the signals by spatial filtering using wideband beamformer; Lastly, we propose two methods for FH signal blind detection and blind parameter estimation, one is for several constant hop-rate FH signals whose dwell-time are different and another is for a single FH signal whose hop-rate is alterable.By employing spatial interpolation in broadband signal beamforming, it can reduce the number of antenna elements and corresponding RF modules, A/D converters, etc. It can also eliminate the mutual coupling between antenna elements while getting the narrower main beamwidth and lower sidelobe level.

本文的主要研究工作和贡献如下：●提出了一种基于窄带处理的FH信号盲检测和参数盲估计的实现方法，即首先求出多路信号之间的互相关，进而得到互功率谱密度矩阵，然后通过对CSDM进行对折处理来抑制噪声、定频信号及其他干扰的影响，并将所有属于FH信号的hop(每一跳的驻留时间在时频图上持续的线段)从CSDM中筛选出来，最后用阵列信号处理中的到达方向估计理论在频域中估计出各个hop的方向参数，利用方位信息完成FH信号分离并得到FH信号的数目及其各自的参数集；●提出了一种确定FH信号检测门限的策略，该策略不仅使得检测门限能够通过理论计算得到，而且还显著地抑制了非跳频信号的干扰，从而能有效地检测出FH信号；●提出了一种基于宽带处理的短波FH信号盲检测和参数盲估计的实现方法，即首先利用宽带空间谱测向技术得到接收信号的DOA，然后采用宽带波束形成技术对特定方向进行空间滤波，实现多个信号的分离，最后分别提出了两种FH信号的盲检测和参数盲估计方法，第一种方法适用于空间某个特定方向上存在着几个驻留时间不同的恒跳速FH信号和其他干扰信号的混合信号，第二种方法适用于空间某个特定方向上仅含一个可变跳速的FH信号和噪声的混合信号；●将空间插值的概念和宽带波束形成技术结合起来，提出了一种基于频域处理的宽带恒定束宽的波束形成方法。

A country squire and his fat wife occupied the tapestried chamber; merry girls scampered up and down the long passages, and young men stared out of the latticed windows watching for southerly winds and cloudy skies; there was not an empty stall in the roomy old stables; an extempore forge had been set up in the yard for the shoeing of hunters; yelping dogs made the place noisy with their perpetual clamour; strange servants horded together on the garret story; and every little casement hidden away under some pointed gable, and every dormer window in the quaint old roof, glimmered upon the winter's night with its separate taper, till, coming suddenly upon Audley Court, the benighted stranger, misled by the light and noise, and bustle of the place, might have easily fallen into young Marlowe's error, and have mistaken the hospitable mansion for a good, old-fashioned inn, such as have faded from this earth since the last mail coach and prancing tits took their last melancholy journey to the knacker's yard.

一个乡绅及其肥胖的妻子住进了挂毯室；兴高采烈的小姑娘在长长的走廊里跳跳蹦蹦，来来去去；年轻的男子从花格窗里向外张望，守候着南风和多云的天空；宽敞的老马厩里没有一间分隔栏是空的了；院子里建起了临时的锻炉，准备给打猎的马儿钉蹄铁；猜猜而吠的狗儿用它们的永远不断的吠声把这个地方弄得喧闹嘈杂；奇里古怪的仆役们成群地聚集在顶楼上；隐藏在尖尖的三角屋顶下面的每一个小窗扉里，离奇古老的屋顶下的每一个老虎窗里，各自在冬夜里闪烁着烛光；夜间行走的陌生人，突然之间遇到奥德利庄院府邸，被这个地方的灯光、声音和熙熙攘攘所迷惑，很可能轻易地重蹈年轻的马洛的覆辙，把好客的府邸当作一个优秀的老式旅馆。自从最后一辆邮车及其腾跃的驽马作了最后一次郁郁不乐的旅行，进入收购废旧车船和无用牲口的商人的院子以来，这样的老式旅馆早已在这大地上消失无遗了。

A husbandman who had a quarrelsome family ,after having tried in vain to reconcile them by words ,thought he might more readily prevail by an example .so he called his sons and bid them lay a bundle of sticks before him .then ,having tied them into a fagot, he told the lads ,one after the other ,to take it up and break it .they all tied ,but tried in vain .then untying the fagot ,he gave them the sticks to break one by one .this they did with the greatest ease .then said the father:"thus you ,my sons ,as long as you remain united ,are a match for all you enemies ;but differ and separate ,and you are undone."

一个农夫，家庭不和睦，用言语劝告大家和好，总是无效，最后他想，用实际例子可能容易说服他们。于是他把儿子都叫来，吩咐他们抱一捆火柴放在他的面前。他把火柴捆成一捆，接着叫这些孩子挨次拿起来折断它，一个个都试过了，但都没有折断，接着他解了捆，一根一根地给他们折，他们都轻而易举地折断了。这时父亲说："孩子们，只要我们团结一致，你们就能对付一切敌人；但是如果意见不合，各自东西，那么你们一定要失败。"

The invention relates to a nut (10) comprising an outer body (16) with an axial passage (22), an inner body which can be movably placed in the passage along an axial direction and which is divided along said axial direction into at least two jaws (18, 20), each jaw bearing an inner thread segment (24) on its radial inner surface, first guiding means (26) located on the outer body, as well as second guiding means (30) located on the jaws and co-operating with the first guiding means so that the jaws are radially displaced towards the exterior when the outer body is displaced in the unscrewing direction relatively to the inner body et radially displaced towards the inside when the outer body is displaced in the screwing direction relatively to the inner body.

本发明涉及一种螺母(10)，它包括：一个带轴向通孔(22)的外体(16)；一个内体，位于通孔(22)中，可沿轴向移动，并且沿所述的轴向方向至少分成两个滑块(18、20)，它们各自在其径向的内表面上具有内螺纹部分(24)。在外体上有第一导向装置(26)，同样滑块上有第二导向装置(30)，第二导向装置与第一导向装置共同起作用，所以，当外体相对于内体沿旋松方向作相对滑移时，滑块径向地向外滑移，并且，如果外体相对于内体沿拧紧的方向滑移，则滑块径向地向内滑移。

Characteristic of Tibetan Buddhism is the unusually large segment of the population actively engaged in religious pursuits (up until the Chinese communist takeover of the country in the 1950s an estimated one-quarter of the inhabitants were members of religious orders); its system of "reincarnating lamas"; the traditional merger of the spiritual and temporal authority in the office and person of the Dalai Lama; and the vast number of divine beings (each with its own family, consort, and pacific and terrifying aspects), which are considered symbolic representations of the psychic life by the religiously sophisticated and accepted as realities by the common people.

藏传佛教的特征就是很多部分的人口积极地忙碌于宗教追求（中国共产党1950年接管西藏的时候，估计有四分之一居民是僧侣成员），有&喇嘛转世&的体制；传统上是精神与当时暂时的行政权威和达赖喇嘛合并在一起；大量数目的神职人员（每一个都有各自的家庭，配偶，有平静和可怕的面貌），被认为是笃信地诡辩象征性地描绘着精神生活，被普通人承认为真实。
