If you run this code with a larger number for the Fibonacci sequence index (say, 12), you'll end up watching output scroll by for a long time.
如果对大的斐波纳契数列(比如说12)使用这段代码，将会看到长时间的滚动输出。
To this end, we attach a "tee" (T-shape pipe) that permits two things at the same time: placing the output into a file AND displaying the output into the screen. The plumbing analogy would be.
为达到此目的，我们连接允许两件事同时进行的“tee ” (t -形管道)：将输出结果放在文件中同时将输出结果显示在屏幕上。
Most of the programs we have seen so far are transient in the sense that they run for a short time and produce some output, but when they end, their data disappears.
目前为止我们见过的程序大多是很短暂的，它们往往只是运行那么一会，然后产生一些输出，等运行结束了，它们的数据就也都没了。
Rising output slowed the decline of state revenues and by the end of 2009 these had grown, year-on-year, for the first time since the collapse of Lehman Brothers in September 2008 (see chart).
财政收入的减少因为产出的增长而放缓，甚至在09年末出现同比增长，这在08年9月雷曼兄弟破产以来还是第一次(见图表)。
The start message is output a second time, the second call to suspend returns immediately, and the end message is sent in response.
第二次输出start消息，立即返回对suspend的第二次调用，并且发送end消息进行响应。
