压缩

Definition Compression ratio is the size of the compressed file as a fraction of the uncompressed file.

压缩比是指已压缩文本的大小与未压缩文本大小的比率

The algorithm realizes the compression for large number of data in high speed and high compression ratio in undamaged way .

该压缩算法在不损失数据的前提下，实现了对海量数据的快速，高压缩比压缩。

Unique compression method, based on space vector compression method, compression ratio is not good, however.

详细说明：独特的压缩方法，基于空间向量的压缩方法，压缩比不大但是效果好。

When we designed the system, we considered some key factors such as the system must deal with and store a great deal video and audio data, the capability of the hard disk in the server and client, hi the part of video compression, we choose the currently MPEG-4 video constringent card to complete the collecting and compression of the video and audio signals .

在论文研究与实用系统设计中，充分关注到大量视音频数据的处理、存储以及服务器和远程客户端的硬盘容量等关键因素，视音频压缩采用了最新的MPEG-4视音频压缩卡进行视音频信息的采集和压缩。

With this fracture model, some important results are obtained for composite thin-walled circular tubes under axial compression; the calculation of the critical delaminate load is gained based on the linear elastic analysis As for the dynamic loading, this delaminated model modified in depth by introducing a dynamic factor will be helpful.

利用该模型本文得到一些重要的结论，并给出压缩载荷临界判据。利用该模型研究复合材料圆管的轴向压缩承载行为，为后继动力轴向压缩问题的研究奠定基础。

This paper gives some analysis of the working process of the screw compressor with economizer, separates it into three stages: quasi-compression process of the low stage, charge-compression stage, and quasi-compression process of high stage, sets up the mathematical models and its solution of the actual process. The capability increscence of the screw compressor with R717 and R22 after using the economizer has been calculated.

在分析带经济器螺杆制冷循环系统工作机理的基础上，本文着重分析和研究了压缩机的工作过程，把带经济器螺杆制冷压缩机的工作过程分成&准低压级压缩&、&充气——压缩&、&准高压级压缩&三个阶段，并提出了反映该循环实质的数学模型，给出了求解方法，计算了R717、R22两种常用制冷工质的螺杆压缩机在带经济器后的性能增长情况。

Under the same vertical pressure, coefficient of compressive deformation decreases with increscent dry density.

在同一压力下，随试样起始含水量的增大压缩变形系数逐渐增大，压缩变形系数与压力的函数关系，结合改进的分层总合法可用于路基压缩沉降量的计算。

It is shown that the generation of the PA effect results from two kinds of contribution only. One is the contribution of so called"thermal piston"--the gas boundary layer adjoining the heated sample which expands cyclically and pushes the rest gas just like piston. The compressing process of it is comfirmed to be isochoric. And the other is that of"mechanical piston"--the thermally expansive sample itself, the compressing process of which is found to be polytropic with a index of (2-〓).

一即是被称为&热活塞&的与材料受热表面相邻的边界层气体周期性热膨胀产生的压缩，其是定容过程；另一是被称为&机械活塞&的材料本身热膨胀产生的压缩，其是多变过程，多变指数为2-〓，γ为绝热压缩因子。

The results show that the degree and period of squeezing depend strongly on the initial parameters, and energy nonconservation item has a great impact on squeezing property.

结果表明，光场的压缩程度以及压缩周期都强烈地依赖于光场初始参数的选取；能量不守恒项对光场压缩特性的影响很大。

In OverEasy mode, the threshold of compression is defined as the middle of the OverEasy threshold region, that is,"half-way" into compression.

在OVEREASY模式中，压缩阀值被定义成OVEREASY压缩区域的中点，也就是说，&中途&被压缩的。
