In the face of above cases, this paper attempts to break through the bottleneck of data security with another way. Through study of Error Correction Code and Finite Field theoretics, this paper tries to apply the Reed-Solomom arithmetic based on Finite Field Galois Field to Redundant Array of Independent Disk, and tries to realize a simple RAID6 level programme, thereby could offer an idea for securer storage device.

面对这样的现实情况，本文试图换个角度突破这个安全瓶颈，通过对纠错编码理论及有限域数学理论的一步步深入研究，尝试将基于有限域数学的Galois域Reed-Solomon算法应用到RAID(Redundant Array of Independent Disk 独立冗余磁盘阵列)磁盘阵列当中，并尝试实现小型的RAID6级别的实验程序，从而为实现更加安全的存储技术提供了思路。

Because the mathematical expressions of the software development process cost function are so complicated and Gamma function is usually applied in statistic theory, so we can deal with this kind of model easily.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
