查询词典 compression of data

In fact, it is probable that little gain can be made by selecting a geometric compression ratio which would raise the gas temperature by adiabatic compression behind the temperature of the hot zones (except for accelerated heating by gas density and proximity effect, which would make it possible to achieve higher RPM).

事实上，它很可能使小增益可以作出选择几何压缩比率，从而将提高的效果，气体温度接近后面的绝热压缩气体密度和温度的热区（除加速它加热能够达到更高的转速）。

The efficiency of the Carnot cycle increases with the compression ratio—the ratio of gas volume at full expansion to its volume at full compression.

在与压缩比，在充分膨胀比的天然气量在全压缩到其批量卡诺循环提高了效率。

In order to help for evaluating properties of soil in interaction more precisely, the paper applies elastic theory solution on different modulus in tension and compression for vertical load into semi-infinite elastic body. Through quoting Heaviside function, the solution of elasticity theory with different modulus in tension and compression is established founded on the solution of elasticity theory for the material incapable in tension and Mindlinsolution for equal modulus.

为使地基土在共同作用中的行为特征评价更为合理，本文应用了半空间问题竖向荷载下地基土的拉压模量不同弹性理论解，该理论解是通过引入Heaviside函数，利用不能承受拉应力材料的弹性理论解并结合拉压模量相等的经典Mindlin解而获得。

The article will mine Data-Item set compression to a Boolean Vector Matrix.The algorithm only needs to scan the database one time and rational use of data storage structure so that it would not generate a large number of candidate sets.

将挖掘的数据事务集压缩到一个布尔型向量矩阵中，只需扫描数据库一次，合理利用数据存储结构，且不会产生大量的候选集。

This article is about data compression and data encryption.

本文是关于数据压缩和数据加密。

Data compression provides a significant (not less than 3 times less) decrease in the volume of data transferred via the network.

数据压缩提供了一个显著性（不低於3倍，以较低者为准）减少，在量传输的数据通过网络。

Portable Document Format is the object to be studied in my paper, which is one of the electronic document formats. How to write image data to PDF is the focus of the study. Image data compression and its application in PDF are studied in-depth in the paper.

本文以电子文档格式PDF为研究对象，以如何将图像数据保存到PDF中为研究重点，深入地研究了图像数据压缩在PDF中的应用。

Wavelet are considered to be a powerful tool both in function representation and data compression, so it is natural to adopt wavelet as tool of compressing geometry data.

小波被认为是进行数据压缩的有力工具，因此将小波用于几何压缩也就是自然而然的事。

Deep researches on relative key technologies of image database, including partitioning, coding and index of image block, query and visualization of image data, image data compression and etc.

深入研究了影像数据库相关的一些关键技术：影像块的划分、编码与索引机制、影像数据的可视化与查询及影像数据库的数据压缩等。

However this advantage is at the cost of massy quantity of data that brings difficulties of images' storage and transmission. So it is very important to search a high effective hyperspectral images' data compression algorithm .

然而高光谱图像的这种具有较高谱分辨率的优越性是以其较大的数据量及较高的数据维为代价的，高光谱图像巨大的数据量，给数据存储和传输带来困难，因此在现有条件下，寻找一种有效的高光谱图像压缩方法具有十分重要的实际意义。

Chinese traditional virtue is humility and wariness,the compliment and praise to the others should be declination
