GUID is pseudorandom number, by the hardware information of the computer with software information (the Office version that founds documentation for example) form, software of the original author that the GUID information that embeds according to making public documentation interior so hunts down this documentation likely, creation and hardware information.

GUID是伪随机数，由计算机的硬件信息和软件信息（例如创建文档的Office版本）构成，这样根据公开文档内部嵌入的GUID信息就有可能查获该文档的原始作者、创作软件和硬件信息。

This Stop message usually occurs after the installation of faulty hardware or in the event of failure of installed hardware (usually related to defective RAM, either main memory, L2 RAM cache, or video RAM).

这个停止信息通常产生于安装了有故障的硬件或者安装硬件的一个错误操作之后（通常与有缺陷的RAM，可能是主存，二级缓存，或者显存有关）。

The paper further realizes a hardware accelerate boundary-scan controller to improve the performance of the remote experiment system. The controller can realize the process of "configuration" and "verify"automatically without the control of CPU. The controllers operation in the remote experiment system can reach the expected goal. By performance analysis, we conclude that hardware accelerate boundary-scan controller is significant faster than that realized with software.

从提升远程实验系统性能出发，本文进一步设计实现了一个硬件加速的边界扫描控制器，该控制器能够完成对目标FPGA的"配置"和"验证"，执行过程中不需要CPU干预，在整个远程实验系统联合调试的过程中，运行完全正常，达到了预期目标，并且通过性能分析证明，硬件加速的边界扫描控制器相比于软件实现，速度有显著提升。

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.
