In this thesis, we will mainly do research on the novel scheme for Digital image Steganography, Digital Image Secret Transmission in network and the development of the information hiding device for application. The main contributions of this thesis are as following: The novel conversion method for mapping image to complex number is proposed, and the plus, minus, multiply and complex conjugate operation of image are defined based on Positional number systems and complex number system. Following new results have been gotten: 1 The suitable complex number basis to be used to express integers is a big set. 2 Any image can be mapping into a one-to-one point. 3 Lots of image processing problem can be considered based on geometric theory.

在本论文中，研究工作集中在数字图像伪装算法的新模型、图像在网络中的加密传输的新方案和信息伪装设备的研发等三个方面，主要包括：基于位值制记数法和复数系理论，提出利用复数作为基底的数字图像新的表示方法，用复数运算定义了图像和图像间的"加"、"减"、"乘"、"共轭"等运算关系；得到理论结果： 1、能表示任何整数的复数基是很大的一个集合。2、任何一幅图像，都能和复平面上的一个点一一对应。3、可以将图像问题化归为平面几何问题处理。4、复数系下的图像表示适合用于信息伪装。

The analysis of molecular variance revealed that 93.85% of the variance component was attributable to the variation among individuals within ditches. Low levels of the genetic differentiation coefficient among ditches, G=0.172 and Nm=2.4, indicated that the ditches barely hinder gene flow between Scaevola populations. UPGMA cluster analysis and principal coordinate analysis revealed no major groupings among ditches or among plants.

经过分子变方分析显示海南草海桐有93.85％的变方成分存在於个体间；POPGENE分析结果显示其遗传分化系数G(下标 ST为0.172，而基因流为2.4，显示沟渠并无阻碍基因交流之能力；UPGMA归群分析及主座标分析结果显示海南草海桐个体间几乎无差别或差异很小。

The cells labeled with PKH26 were seeded on the bio-derived bone to construct tissue engineered bone in vitro. Then the compound of cells and material were observed under fluorescence microscope. The compound of labeled cells and material were implanted into the rabbit thigh muscle, and the transformation of the labeled cells was observed by fluorescence microscope 14 and 28 days later.

将PKH26 标记的BMSCs 接种于生物衍生骨材料，48 h 后荧光显微镜观察细胞与材料的复合情况；将细胞-材料复合物植入成年新西兰大白兔双后肢肌袋，14、28 d 后荧光显微镜观察标记细胞的转归。

Exactly one month before the wedding party, till now I just get chance to catch up with my 'comrade in arms', my: host, wedding supervisor, make-up artist, photographers, chocolate maker, my alliance, and my long-distance but always caring groom, our battle is just about to start.

离婚礼恰好一个月的时间，从西面回到东面，才有机会看订好的酒店，才有机会和各路人马真正开始讨论婚礼的各项事宜细节，我的司仪，我的督导，我的化妆师，我的摄影摄像，巧克力制作，我的各位同志们，还有我那还在远方，暂不能归，却时时牵挂的新郎，我们的战斗开始了。

In this paper the natural boundary reduction for some elliptic boundary value problems with concave angle domains and its natural boundary element methods are investigated.

本文研究凹角型区域椭圆边值问题的自然边界归化及其边界元法。

Part II, the artificial boundary condition and its numerical methods based on natural boundary reduction for a hyperbolic initial boundary value problem in an infinite domain with a concave angle is investigated.

第二部分，研究一类具有凹角的无界外区域的双曲型初边值问题基于自然边界归化的人工边界条件及其数值方法。

When it is concentrically banded it is called by the subvaritey name agate.

如果玉髓有同心圆的带状花纹(当然，花纹似乎往往更"狂野"一点=^w^=)，它就被归为玛瑙这一亚种。

This will lead the recursive traversal algorithm to follow both the paths, the instruction immediately after the conditional jump instruction and the target of the jump instruction, potentially leading to an inconsistent state.

它将引导递归遍历算法跟随这两个路径：条件跳转指令之后紧接的那条指令和跳转指令的目标，潜在地导致一个不相容的状态。

The recursive traversal method can be fooled by placing garbage data after a conditional jump instruction and programmatically ensuring that the jump condition always succeeds.

通过在一个有条件跳转指令之后放置无用数据、并且有规划地确保跳转条件总是跳转成功，能够欺骗递归遍历方法。

"In logic, a relation that holds between two propositions when they are linked as antecedent and consequent of a true conditional proposition."

在逻辑中，指两个命题被归为真实条件命题的前因与后果时二者之间的关系。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
