A new method of unitary space-time constellation, which can improve the influence on block error rate by fast fading, is designed based on a systematic method.

在系统化酉空时星座设计方法的基础上，提出了一种抗信道快变的酉空时星座设计方案。

Using the subshell, you can collectively redirect their standard and error output for the entire block instead of for each individual command.

通过使用子外壳，可以对整个块（而不是单个命令）的标准和错误输出进行集体重定向。

One day, the error report started logging problems about a bad block being unable to relocate itself on one of the disks.

有一天，错误报告指出在其中一个磁盘上坏块无法重新定位。

That says it's in here. It's in this tri-block. It raised an exception, but it wasn't and I O error.

这在这里它是一个try程序块,它报出异常，但他不是io错误。

And so I've done a little bit different things here which is I put the accept part of the block with I O error.

所以我这里在处理部分,所做的同io错误，有一点不一样,这表明什么。

We also saw a brief demo of the prototype application, and sure enough, it showed us when an LED block was placed backwards with an error message -- you can see it in action in the video below.
