To increase the security of the watermark, a new binary image encryption algorithm based on TD-ERCS map is presented. The watermark is encrypted by a chaos sequence generated by TD-ERCS map; A novel color image watermarking algorithm is proposed based on discrete chaotic map and 2-dimensions discrete wavelet transform. The watermark is encrypted by the new binary image encryption algorithm, and the encrypted watermark is embed into four sub-bands of the most deep level of blue branch of host image by three-level wavelet transform, and the embedded positions are determined by general cat cha otic map; A novel color-image blind detection watermarking algorithm is proposed based on integer wavelet transform and subsampling. The scrambled watermark is encrypted and embed into the low sub-bands after four sub-images of the Y branch of host image is transformed by two-level wavelet transform, and the embedded positions are determined by Logistic chaotic map, this watermarking scheme can realize blind extraction.

为了提高水印图像的安全性，提出了一种基于TD-ERCS混沌映射的二值水印图像的加密算法，该算法利用TD-ERCS映射产生的混沌序列加密水印图像；将离散混沌映射和二维离散小波变换相结合，研究了彩色图像水印新算法，该算法先对混沌序列加密后的水印图像进行小波变换，再嵌入到宿主图像的蓝色分量的最深层的四个子带中，嵌入位置则由广义猫映射确定；将整数小波变换和图像子采样技术应用于数字水印，提出了一种彩色图像盲提取水印算法，水印嵌入时，先对宿主图像在YIQ色彩空间中的Y分量进行子采样，并对得到的四个子图像分别进行二级离散小波变换，然后将置乱并加密后的水印图像嵌入到小波变换后的低频子带中，其嵌入位置由Logistic混沌映射产生的混沌序列确定，实现了水印的盲提取。

Then this thesis presents another SLAM algorithm-the Relative Map Filter, The RMF is however disadvantaged by the inability to guarantee consistency of the estimated relative map. The following sections introduce a new navigation filter - the Geometric Projection Filter or GPF. The consistency of the estimated relative map is enforced by the application of the constrained estimator to an inconsistent relative map produced by a standard RMF.

然后介绍了SLAM问题的结构，分析了绝对地图滤波器的性质，介绍另一种解决方法—相对地图滤波器，但是相对地图滤波器产生不一致的相对地图，因此在相对地图滤波器的基础上应用约束估计产生一致的相对地图，这就是几何投影滤波器，从而有效的解决了SLAM问题。

The results show that the SI value of MAP is the logarithmic function of the mass concentration of P, of ammonium N and of Mg, respectively, and increases with the increase of the mass concentration of each element, The SI value of MAP is a polynomial function of the solution pH value, and the optimum pH value for the crystallization of MAP is 9.0 and increases slightly with the increase of N/P. Moreover, the SI value of MAP is a power law function of the solution ionic strength but decreases with its increase.

计算结果表明，磷酸铵镁的饱和度指数与氮、磷、镁的质量浓度分别呈对数函数关系，并随任何一个因子的增大而增大；与溶液pH值呈多项式函数关系，结晶反应的最佳pH值为9.0，并随溶液中氨氮与磷摩尔比的增大而略升；此外，磷酸铵镁的饱和度指数与溶液离子强度呈幂函数关系，随离子强度的增大而减小。

On the net collect summed up the following respects, offer text to receive the main page on the site repeatedly, according to website size, more or less can webpage numerary receive all pages repeatedly even; For every join provides a brief introduction, in order to hints this one's duty allows the person that visit is about which on one hand; Exceed in website map and text the mainest crucial term alludes inside join, the help searchs theme of page of join of engine identifying place is about which on one hand; Help engine indexes a few dynamic pages, because a few pages will be of dynamic generation, if not be user behavior is called,will not show come, can put this join on website map, in order to help the dynamic page with engine main index; To make website map attracts the visit of network spider, the descriptive sex statement with go up certain must be written to use this connective keyword to have simple description at the back of join, but the use keyword that cannot transfer, can be just the opposite to what one wished otherwise; Because general spider catchs page of before 3 class only, so website map makes the same score better more, what point to here is logical way, is not physical method.

在网上搜集总结了以下几个方面，提供文本连接到站点上主要的页面，根据网站大小，网页数目的多少甚至可以连接到所有的页面；为每个连接提供一个简短的介绍，用以提示访问者这部分内容是关于哪一方面的；在网站地图和文本超连接里面提及最主要的要害词语，帮助搜索引擎识别所连接页面主题是关于哪一方面的；帮助引擎索引一些动态页面，由于一些页面将是动态产生的，假如不是用户行为调用将不会显示出来，可以将此连接放在网站地图上，以帮助引擎索引重要的动态页面；为了使网站地图吸引网络蜘蛛的访问，一定要在连接后面写上一定的描述性语句并使用此连接的要害词进行简单描述，但不能过渡的使用要害词，否则会适得其反；因为一般蜘蛛只抓前三级页面，所以网站地图越平越好，这里指的是逻辑路径，而不是物理路径。
