Part i tries to track to the history of education trend of thought of anarchism in china . it includes 4 phases : introduction ( the end of 19 century - 1902 ), development ( 1902 ~ 1911 ), bloom ( 1912 ~ 1921 ), eclipse ( 1921 - 1927 ). part n analyses education ideas of the faction of china anarchism . lt includes tian yi faction , new century faction , min sheng faction , the faction of anarchical communism . part hi puts forward my evalution form there different angles . generally speaking , it had special significance in special time . even though it had many flaws , it is important for us to value education trend of thought of china anarchism

There was a large amount of information in the whole cathedra,including the importance of information security and how to pledge the security of computer effectively.But I thought if adding more interactive parts,it would be better.

整个报告蕴涵的信息量比较大，从各个方面阐述了信息安全的重要性以及如何更为有效地保证计算机的安全，但我想如果能够适当地多增加一些互动环节，效果是不是更好？

Clothes from different stages of Armani's career are displayed in a loose narrative arrangement, and many of the designs feature his trademark color, the mixture of grey and beige that came to be known as "Armani greige."

亚曼尼在不同阶段设计的服饰，分别不规则地呈现在各个主题区。他众多的设计均能明显地展示他的品牌色彩：将灰色及米黄色调配而成的"亚曼尼米灰色"。

Furthermore, it is not worth to transmit reactive power for long distance. Control provided "on the way" in transmission line, connation nodes, distribution station and other points requires installation of capacitors or\and reactors.

此外， 远距离地传输无功功率是没有必要的，无功功率在传输线路，各个节点，配电站和其他需要安装电容或者电抗器的地方被人为地控制着。

In order to evaluate the image scrambling degree effectively,the paper gives difinition of the continuity extent.And a new evaluation method of image scrambling degree based on the number of the continuity extent changes when the positon of the pixel changes is provided.The simulation result shows that the method can measure the impact of the every image scrambling phase.

为了对其进行有效地衡量，给出了图像连续性区域的定义，并根据置乱前后数字图像连续性区域数量随像素点位置的变化而改变这一原理，提出了一种有效的图像置乱程度衡量方法，实验表明，该方法能够清楚地反应图像在各个置乱阶段的置乱效果。

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。
