The result tells that at the beginning of English learning, semantic competence plays a major part in causing pragmatic failure while in the senior stage; social cognitive competence is the major cause. The thesis based on the research result establishes a semiotic Competence Cultivating Teaching Model in which markedness theory ,theory of interlanguage and interculture and content teaching approach are used to improve semiotic competence and reduce pragmatic failure.

研究结果也对语言学习者和教授者提出了一个新的问题,即在语言教学过程中,如何适当考虑语义能力,解释能力和社会认知能力三者的关系,构建一个教学模型,可以把这三者整体纳入语用能力培养的方案之中,笔者尝试性的提出一个解决方案,借用当前的词义习得标记性理论,过渡语与过渡文化理论和内容教学法理论,构建了一个符号能力发展模型,认为该模型将有利于学习者提高符号能力,进而减少语用失误。

After certifying the irreality of ideal filtering function, we can get a better filter selecting a proper window function. Comparing two actual filters, we designate a good"Panama hat"filtering function. Meanwhile, an effectively linear interpolating function is introduced to raise the image reconstruction quality. Describing its realizing steps on the micro-computer briefly, we reconstructed some images from the anlogue projections of some models. The number of projection views is 180, 100 same interval parallel lines per view; the size of reconstructed images is 64×64 pixels with 64 gray levels; the reconstructing speeds are 40" on PC-386 and 12"on PC-486, respectively; each pixel is 0.31mm.

The stude announces that their changeable regular of the center of gravity level speed in supporting phase is falling in tne first cushioning phase. When their center of gravity's vertical lines pass their heels and their knee joints go on extended contraction ,their center of gravity level speed has extended .the reason is that their angles have passed the heels and their swinging legs' kenn joints have swinging the front of their bodies. Its power originates the swinging leg's forward active swinging and the decurtation contraction of hip joints 、ankles of the supporting legs.the swinging leg shows "the calf's active backward swinging"before its landing impact,the skill affects the loss of center of gravity level speed when the swinging leg lands.they enlarge their trunks' forward-landing impact phase ,it can decrease the center of gravity level speed's loss after landing and impel the center of gravity level speed to pass the supporting spot quickly.

两人缓冲阶段身体重心水平速度变化规律是在体前缓冲阶段呈下降趋势;当身体重心垂线超过脚后跟后,在膝关节继续缓冲做退让收缩的情况下身体重心水平速度开始加大,原因是踝关节在最大缓冲时身体重心已移过支撑面及摆动腿膝关节已做体前摆动,主要动力来源于摆动腿的积极前摆和支撑腿髋、踝关节的克制性收缩;在摆动腿下压着地前期是大腿积极下压小腿随大腿的积极下压顺势向前下滑摆,在摆动腿下压着地后期表现出"小腿积极回摆"技术,对减小着地时的水平速度损失、加大向前用力都有积极影响;适当加大摆动下压着地阶段躯干的前倾角度,有利于减少着地时相的速度损失和有利于身体重心较快的移过支撑点;缩小后蹬结束后的后伸动作幅度,有利于减小腾空时间。

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。
