嵌入

This paper mainly studied the semilinear biharmonic elliptic equation with multi-singularity and critical exponcnt,in which we mainly studied,where N≥5,k∈N,(λ_1,λ_2,…,λ_k)∈R~4,(a_1,a_2,"",a_k)∈R~(4n) and 2~*=2N/N-4 is the critical Sobolev exponent.

文章主要在有界域Ω中研究了如下含多奇性的半线形椭圆型问题其中N≥5，k∈N，(λ_1，λ_1，…，λ_k)∈R~k，(a_1，a_2，…，a_k)∈R~且2~*=2N/N-4是临界的嵌入指数，由于Sobolev嵌入失去紧性，所以文章将通过集中紧原理得到正解的存在性。

But he draws a distinction between his 'technology' and methods like drugging bugs or inserting tiny metal spears into their jaws -- the insect equivalent of a razor blade in a boxing glove.

但是他将他的"技术"与给蟋蟀喂兴奋剂或在其颚上嵌入小铁刺（这就相当于给拳击手戴上了嵌入刀片的拳击手套）等方法相区别。

For example, a watermark is embedded in the luminance component and a cyclically shifted version thereof in the chrominance component of a video signal.

例如，将水印嵌入在视频信号的亮度分量中，并将其循环移位版本嵌入在视频信号的色度分量中。

In the discrete wavelet transform domain, the watermark information is embedded by quantifying the coefficient of the transform domain andthe watermark can be extracted without the original audio.

This dissertation selects two-dimension binary image as watermark information, and selects audio as embedding object, and embed the watermark in the coefficient of the DFT domain, the DCT domain, the DWT domain.

本文以直观的二值图像作为水印信息，以音频数据为嵌入对象，分别在离散傅立叶变换域、离散余弦变换域、离散小波变换域的系数上嵌入水印。

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。

With the help of the Mountain-Pass Theorem lacking Palais-Smale compactness condition (PSc condition and by adoption of the best attained function of Sobolev embedding, the paper proves the existence of nontrivial solutions of two classes of critical biharmonic equations on boundary conditions by overcoming serial difficulties caused by loss of compactness due to Sobolev embedding.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
