And also it was marvel to see in that castle how by magic they make a compost out of fecund wheat kidneys out of Chaldee that by aid of certain angry spirits that they do into it swells up wondrously like to a vast mountain.

利奥波德爵士为曾莅临学生食堂之最佳宾客，彼乃将手伸到母鸡[20]下腹之最温顺和蔼的丈夫，亦为世上最忠实地向贵族小姐奉献爱情之骑士，遂殷勤地干了杯。

When the gimp, now I knew he was the storekeeper and administrators, was telling to a kitchen our ration, I looked at all round the kitchen quickly with near-sight eyes, I found the towel for cooking bun chucked on the chopping board, was stained with much bun residue.

在瘸子——现在我知道他是队上的保管员兼管理员——向炊事员嘀嘀咕咕地交待给我们按多少定量打饭的时候，我的近视眼迅速地在伙房里睃巡了一遍：扔在案板上的笼屉布，沾着许多馍馍渣！

You may well find that once this period of cogitation is over, you decide that you will indeed proceed ahead as you had originally planned, however, if you do some thinking about it all now, then when it comes to making your final, definitive decision, you'll feel all the more convinces that it's a good move.

一旦这个沉思的阶段过去，你将欣喜地发现，你决定照原先计划的那样确确实实地向前进。然而，如果你现在多考虑一些，在做最终决定的时候，你将感到有更多的证据让你确信这的确是个好的动作。

Once there was a dog who liked to grab and bite others without any reason.so,every hosts of he host thought it was such a troublemaker.therefore,his host encircled his neck with a bell in order to warn others his coming.the dog felt so proud of it that he walked around conceitedly and made the bell ring to show off satisfiedly.howerer,an elder dog came to him and said :stop attitudinizing ,my dear friend.you think the bell is an award for your contribution,don't you?

从前有只狗经常无缘无故就抓人咬人，每个到它主人家的人都觉得它是个大麻烦。于是主人在它脖子上套了个铃铛，以警告人们它的存在。有了铃铛，狗感到非常自豪，还常常趾高气扬地游荡，满意地拨弄铃铛发出清脆的响声来向人们炫耀。但是，一条老狗走过来对它说道：别再装腔作势摆架子了，我的朋友。

If you are free of guilt, then turn earnestly to God for a new consecration.

如果你没有罪，就热切地归向神，把自己全然地献上。

The coxswain told me how to lay the ship to; after a good many trials I succeeded, and we both sat in silence, over another meal.

副水手长教我怎样掉转船头向风停驶，经过多次试验后终于成功地把船停下来。然后，我们静静地坐了下来，又吃了一顿。

I crept from the room and hurried to the phone. I would call my father. I would say,"I love you."

我轻轻地走出房间，急匆匆地向电话走去，我要给我父亲打个电话，对他说一声，"我爱你。"

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。

On mountainous sites, grade Ⅰ or Ⅱ stands including land below the crown of the secondary broadleaf forest and the Chinese-fir plantation or east-facing, shady dry land could be considered for the plantation. The transmittance of crown in the areas should be 55%~60%. One-year-old high quality seedlings above 25 cm tall and 0.25 cm in diameter near the ground-level should be used. For high-yield, field cultivation, shading facility should be considered and seedlings of taller than 15 cm and greater than 0.15 cm in diameter near the ground should be applied. The appropriate density and sunlight transmittance ought to be 30 cm×30 cm and 50%, respectively.
