Collarband, no occupiers whether round, square, acuminate or in ironing all keep it open deformation, had better be fixed shape and ironing, If there is a lead of iron wire, don't general plait, just after death, while it is still hot, with warm hands, gently press fold look like this will lead to live.

领口部位，无领者不论是圆形，尖形或方形，在整烫时都注意不要把它拉开变形，最好是固定形状再加以熨烫；如果是有领片的，不要将领褶线烫死，只要再烫以後，趁它还是温热的，用手翻折轻压，这样子领片看起来会比较活。

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。

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 .

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。

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。"
