The main work and innovation1 In general , a image compression method has different effect to different image . Some are fit for image which has much high frequency . Some are fit for image which has much low frequency .This paper analysis the applicability of fractal algorithm . In this dissertation , an improved algorithum is given . The basic algorithum without eight change and the joint use of quantitative coding , The compression ratio and PSNR can be adjusted , and it can get more quickly speed of coding .2 To a group of exact fractal code , the decoding image can be any resolution .With this characteristic ,choose the proper domain block and range block,this paper get an algorithum which can get higher decoding PSNR and speed than the basic fractal algorithum.3 Give a new method to calculate the scale factor . The calculation of basic algorithum is complex and enormous . The factor of scale is an important variable of the basic algorithm. Now there are two methods to calculate the factor of scale .A new method was given to calculate the factor of scale. The calculation load and complexity are reduced by the new method. Compared with the basic algorithm , the method can reduce coding time.4 The basic fractal algorithum is based on the Collage theorem and contraction mapping theorem . A mathematic model based on basic fractal algorithum is given .

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。

Small mud mounds accumulate to form a big mountain. Creeks converges to form a river. A great man gathers the mass to form a group.

小泥丘累积在一起，从而形成了一座大山；小溪汇流而成江河；一个伟大的人，他聚合大众而成为一个团体。

The theoretical plasma concentration versus time was calculated for all patients on the basis of the pharmacokinetic models described by Sheiner et al. Predicted effect versus time was calculated by following the pharmacokinetic-pharmacodynamic link model. The Ke0 was estimated by fitting a sigmoid cure. Group B was given the drug in a bolus of 2 mg.kg-1 and the Ke0 was calculated according to the method reported by Minto et al.

22例ASA ⅠⅡ级择期手术患者，A组(n=11)持续输注罗库溴铵0.03 mg·kg-1·min-1直至4个成串刺激降至20% 30%，B组(n=11)单次注射罗库溴铵2 mg·kg-1.A组血浆药物浓度用Sheiner等报道的药代动力学参数模拟计算，预测效应根据药代动力学-药效学关系公式换算，Ke0通过S型曲线拟合计算。B组采用Minto等提出的方法计算。

You may look at a group of cows standing under the trees or catch a bee at his early drink in a morning-glory bell, and you would laugh if any one should ask you whether you can tell an animal from a plant.

你可能看到站在树下的一群牛或着一只蜜蜂一大早在牵牛花上汲取露水，如果有人问你能否区分开动植物，你会大笑起来。

You may look at a group of cows standing under the trees or catch a bee at his early drink in a morning-glory bell, and you would laugh if any one should ask you whether you can tell and animal from a plant.

你可以观看伫立树下的牛群或者捕捉清晨在牵牛花冠中吮吸甜汁的蜜蜂，这时如果有人问你能否区别动物和植物，你会觉得好笑。

One theory is that it was named for a group of poets who wrote in Limerick in the 18th century; another, that it came from a custom at parties of making up a nonsense verse and following it with a chorus of Will you come up to Limerick.

一种理论认为它是源于18世纪在利默里克写作的一群诗人；还有一种看法认为它是源于一种集会上的风俗，这种风俗要求写完一毫无意义的诗后众人合唱"你将去利默里克吗"。

Looking back from this path in a northwestern direction one can obtain a magnificent view of the wooded heights which stretched across the Lushan Valley. small path branched off to the northeast and led steeply to a charcoal kiln, then turned in a northwesterly direction past a group of temple ruins to the side valley.

从这条路上往西北方向看，你可以看见高大的树木布满了整个山谷，有一条东北方向的陡峭的岔路通向炭窑，然后又朝西北方经过一些寺庙的遗迹通向侧谷。

If suitable, volunteers may either be placed in a group to support a paid tutor or may work with a student on a one-to-one basis.

假使适当，义工可能会被安排在一个团体内来支援一位有薪水的助教，或可能是与一位学生做一对一为主的工作。
