The algorithm performs discrete cosine transform on sub image of host image, which is cover by visible watermarking, and compresses sub image by select the set of visually important DCT coefficients. Then, the algorithm hides the compressed sub image, which is encrypted by the hash function that is constructed by Rijndael code, in the high coefficient of wavelet domain.

算法将水印图像与宿主图像进行融合，并对隐藏子图采用DCT变换，按Zig_Zag排序保留视觉重要DCT系数的方法作压缩处理，并利用Rijndael密码构造单向Hash函数作加密处理，最终分散嵌入到宿主图像的带参数的整数小波域中的高频系数，实现了可见水印的有效嵌入。

The paper includes:The author calculate the structures inner force and displacement of the free end , analyze the influence of the height and the value of pretress of cable by making use of ANSYS 9.0 soft, pose the concept of critical prestress,conclude the function relation between displacement of the free end, initial strain and the height of cable ,analyze the dynamic properity and point out that Newmark-β method should be adopted when we analyze the dynamic properity of the cable-stayed spatial structure with direct integral test to guarantee the contribution of high mode,finally conclude the functional relation among coefficient of earthquake inner force, initial strain and the height of cable, wish to get some helpful conclusion applied to cable-stayed spatial truss design.

本文系统介绍了斜拉空间桁架竖向地震反应的分析理论与方法、详细分析了斜拉空间桁架结构在静力和竖向地震作用下的受力性能，主要内容包括：利用通用有限元软件ANSYS9.0计算了斜拉空间桁架在静力和竖向地震作用下内力及自由端位移分布规律并得出地震内力系数与节间位置、预应力以及斜拉索高度之间的函数关系；详细分析了斜拉索中施加的预应力以及斜拉索高度的变化对于该种结构内力及自由端位移的影响并提出了斜拉空间桁架的临界预应变概念，进而得到了自由端位移与初始预应变以及斜拉索高度的函数关系，即：△=-(40h+2180)ε+9.8；分析了该种结构的动力性能，并指出：在时域内采用直接积分法计算该种结构的动力响应时，应该考虑采用不引起振幅率减小的Newmark-β法，以保证高阶模态响应的贡献仍然保留在响应中而不致于被忽略。

There can be no doubt, I imagine, that modern ideas on the subject of crime are based upon two assumptions contended for by the Church in the Dark Ages-first, that each feudal ruler, in his degree, might be assimilated to the Roman Magistrates spoken of by Saint Paul; and next, that the offences which he was to chastise were those selected for prohibition in the Mosaic Commandments, or rather such of them as the Church did not reserve to her own cognisance.

我以为，毫无疑问，对于犯罪问题的各种现代观念，都根据"黑暗时代"教会所主张的两种假定——第一，每一个封建统治者在他的地位上得比拟于圣保罗所谈到的罗马高级官吏；其次，他所要惩罚的罪行是"摩西十诫"中规定要禁止的，或是教会并不保留在其自己审判权之内的。

Its author's bizarre cognomen is his own invention; and, of course, this mask — through which two hypnotic eyes seem to glow — had to remain unlifted in accordance with its wearer's wish.

而本书作者的奇特的笔名这是他本人起的——按照他的遗愿，这个新奇的笔名理所当然的被保留了下来。

A group of researchers in Princeton University have managed to prove and demonstrate that disk encryption mechanism used by BitLocker of Windows Vista; FileVault of MacOS X; dm-crypt of Linux, TrueCrypt and possibly other secure encryption software, can be cracked, hacked and defeated by imaging state of physical memory which still carry and retain traces of code bits, in what hackers called cold boot attack by dumping all data in memory to disk.

一组研究人员在美国普林斯顿大学已成功地证明，表明磁盘加密机制，利用BitLocker的Windows Vista的； FileVault的MacOS下；德国马克，隐窝的Linux ， TrueCrypt ，可能还有其他安全的加密软件，可以被破解，黑客入侵并打败由成像状态的物理内存，其中仍保留痕迹的代码位，在什么所谓的黑客攻击冷启动倾倒所有的数据在内存到磁盘。
