It presents a new method for automatically segmenting brain parenchyma and cerebrospinal fluid in routine single-echo MR images. This method is based on the weak membrane model.
提出一种自动分割单通道磁共振脑图像的新方法，这种方法建立在弱膜模型的基础上。
The first echo statement uses the single > to force the creation of a new file.
第一个echo语句使用单个的 >强行创建新文件。
Bats are the only mammal capable of flying and are so highly evolved to be capable of pinpointing a single insect flying in the pitch black and plucking it out of the air using echo location.
蝙蝠是唯一会飞的哺乳动物，进化程度很高，能够在一片漆黑中精确定位一只飞虫的位置，并利用回波定位准确地从空中捕捉。
If you're appending only a single line instead of multiple lines or an entire file, you can use echo instead of cat.
如果您仅追加单行而不是多行或整个文件，您可以使用echo而不是cat。
Did you also notice the use of double-quoted strings instead of single-quoted strings on the echo line?
另外，你注意到在echo一行它使用了双引号而不是单引号吗？
you could use the following code to replace the multi-echo statement, and UNIX would only need to process a single execution
可以用以下代码替换多个echo语句，UNIX 只需处理一次执行
Some methods of enhancing detection performance in dealing with the single pulse echo signal and the multi-period pulse bunch echo signal by accumulating are summarized.
