本文的主要工作及创新点主要包括以下几点：1一般情况下，一种图像压缩的方法对不同特点的图像，压缩效果会有所不同，本文利用分形压缩编码对不同特点的图像进行编码，分析了分形编码对不同图像的编码适用性，利用去掉8种变换的分形编码算法与简单的均匀量化编码方案相结合，得到了一种可以调节压缩比与解码质量的分形编码方案，该提高编码速度6倍以上。2分形编码的特点之一是分形解码的分辨率无关性，即对于一组分形编码可以将其解码到任意分辨率下，本文利用分形编码的这一特点，结合不同的量化编码方案，选择合适的定义域块与值域块及适当的编解码分辨率，得到了一种提高解码质量，编码速度提高12倍以上的加速算法。3比例因子是基本分形算法中的一个重要变量，目前有两种计算比例因子的方法，文中给出了一种新的求比例因子的方法，该方法简化了求比例因子的计算，从整体上减小了基本分形算法的计算量，简化了算法4分形压缩的数学基础是不动点定理与拼贴定理，本文根据基本的自动分形编码方法，建立数学模型对其进行推导，得到了用普通数学的极限理论解释分形编码的数学表达式，从而对由基本分形编码得到的解码图像中的像素点的值给出了确定的表达式。

Confronted with the new course reform, the teacher is not to turn his role into other roles, but to determine anew in accordance with the requirements of new course his own professional connotations, which are expressed in the following "5-er/or＇ s": The teacher is a service performer of the students, which is the essential characteristic of the role, showing the nature and the working attitude of the teacher; he is a promoter of the students＇study, which is the kernel characteristic of the role, normalizing his teaching behavior; he is a cooperator of teaching and study, which is the basic characteristic of the role, normalizing the equal relation between the teacher and students as well as between teaching and study ; he is a constructer of the new course and a teaching - study researcher, which are the significant characteristics of the role, normalizing his specialty research and advanced learning and improvement.

面对新课程改革，教师不是把自己的角色转变为其他角色，而是根据新课程的要求重新确定自己的职业内涵：教师是学生的服务者，这是教师角色的本质特征，表明教师的性质和工作态度；是学生学习的促进者，这是教师角色的核心特征，规范教师的教学行为；是教与学的合作者，这是教师角色的基本特征，规范师生平等的教学关系；是新课程的建设者和教学研究者，这是教师角色的重要特征，规范教师的专业研究与进修提高。

The reliability of analysis result depends largely on the in-house experimental conditions. Unlike the previous analysis that only concerns the sole effect of permeable pressure, this article considers both permeable and confining pressure and deformation characteristics of concrete material under the interaction of them according to the real work state of construction, which may leads to the changing pattern of permeable rate as listed below: permeable rate always reaches its peak with the time process going on, than goes down and remains straight on some certain value; The PR will tend to decline while the confining pressure is increased, and the time taken before the peak will be extended as well; Under the constant permeable pressure and circularly changing confining pressure, the minus-exponential ascend and descend relationship could be applied between the PR and Time axes respectively with crannied and intact concrete samples, and the PR of crannied concrete is far more larger than that of intact concrete. The change pattern of concrete could also be mathematically analogized using the least square method.

室内的实验条件是研究成果可靠性的重要因素，而以往的研究都只考虑了渗透压单一作用，本文根据混凝土结构的实际工作状态，同时考虑了围压与渗透压共同作用下的混凝土材料的渗透性变化特征，得出了混凝土材料在围压作用与渗透压共同作用下的渗透率的变化规律：渗透率都是随时间推移先达到一个峰值，再降低并趋于平稳；渗透率会随围压的增大而减小，并且峰值的到达时间也会随之延长；在渗透压不变，围压升降循环的情况下，有裂缝、无裂缝混凝土的渗透率变化规律是随时间成负指数关系上升、下降，且有裂缝混凝土试件的渗透率远远高于无裂缝混凝土的渗透率，并对混凝土的变化规律运用最小二乘法进行数学拟合。

德育是学校各育之首，在学校教学中处于首要的、核心的地位。在当前社会变革中，面对小学传统德育教育模式和内容对社会现实的不完全适应，社会传媒及网络对学校德育的负面影响，如何做好小学德育工作，使小学生迈好人生的第一步，打下扎实、良好的道德品质基础，成为迫切需要我们解决的一个重要课题。
