The digital watermark was hided by the modification of DCT coefficient of chromatism in the YC_bC_r, the matrix of chromatism was disparted into 8×8 blocks, which were divided into two types by the density of edge point, then the watermark components with different strength were hided into the blocks according to the classification.

利用彩色图像在YCbCr域内对色差分量的DCT系数的改变加入水印，将色差分量矩阵进行8×8分块，根据每个小块内边缘点的密度将所有小块分成两类，不同类的小块分别按照不同的拉伸因子，加入水印信息。

As to the shortage of goals up front , I am as flummoxed as everyone else , except to say that it will change .

对于攻击线进球不多，我像每个人一样困惑，希望这点能有改变。

I grew up hating Liverpool," he said,"and that hasn't changed.

He noticed this, and thrust at an inner door with the end of his spade, intimating by an

他注意到这点，就用他的铲子头戳戳一扇黑门，不出声的表示如果我要改变住处，就非走这儿不可。

The shortages of typical BP algorithm are that its convergence speed is slow and it possibly mires to local minimum. To solve the former shortage, BP algorithm was modified from several aspects, such as adjusting learning rate adaptively, adding momentum factor, preprocessing training data and modifying network structure, etc.. For the latter shortage, factor γ was introduced to avoid most of local minimum and accelerate the convergence speed.

为解决现有BP算法收敛速度慢的问题，对BP算法进行了改进，采用了动态改变步长、加入动量因子、对训练样本进行预处理以及调整网络结构等措施；针对经典BP算法可能收敛到局部极小点的问题，加入γ因子，可以避免大部分的局部极小值，从而使网络的收敛速度加快。

Maybe it is because we are more offensive - but it is not because we are changing the system.

&可能是因为我们进攻火药点太猛，但是并不是我们改变系统的缘故。&

Q: Have you ever thought about changing your style and trying your hand at more pessimistic work?

问：您有想过改变风格，尝试一些悲观点的作品吗？

On the basis of atmospheric corrosion analysis and on the premise of unaltered originappearance of metal antiquity, a novel systematic technology of rust stabilized conversion and corrosioninhibition for archeological iron was developed in this thesis. Model occulted corrosion cell was used to studythe formation of bronze powder rust, its characteristics of pit corrosion and effect factors. The filmingtreatment of azoles composite corrosion inhibitors was used to prevent silver tarnishing, and its anti-tarnishingmechanism was proposed by measurement of electrochemical techniques and Surface-enhanced Ramanscattering.

在不改变文物原状的前提下，本文基于对金属质文物大气腐蚀过程的分析，发展了一种新的铁器文物表面锈层稳定转化与缓蚀保护的系统处理方法，用&模拟闭塞电池&的方法研究青铜器文物&粉状锈&的形成、点蚀特征和影响因素，采用唑系复合缓蚀剂成膜处理技术防止银器文物变色，利用电化学方法、SERS等方法研究并提出了唑系复合缓蚀剂防银变色的作用机理。

Traditional literature and reader meet is a kind of enclosed home remedy peddles, and network literature is in the reader pay close attention to all the way and breathe out go into battle of the convoy in drinking sound, its give those who rise to be born even if accompanying a hit to grow all the way, it is the creation of a kind of open mode, the reader's opinion and attention can change the direction of creation and outcome even.

传统文学与读者见面是一种封闭式的单方叫卖，而网络文学则是在读者的一路关注和呼喝声中护送上阵，它的出生就是伴随着点击率一路成长起来的，是一种开放式的创作，读者的意见和关注甚至可以改变创作的方向和结局。

Their models, physiognomies and cephalometries before and after treatment were compared.

结果：矫治后前牙覆牙合覆盖正常，软组织凹面面相改善，&B&点后移，ANB角，Wits值发生显著改变。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
