This produced no output, because the "d" command zapped every single line in the pattern buffer!

这不会产生输出，因为“d ”命令除去了模式缓冲区中的每一行！

Once a line was read into the pattern buffer, it performed the 'd' command and printed the contents of the pattern buffer (nothing in this example).

一旦将一行读入模式缓冲区，它就执行'd '命令，然后打印模式缓冲区的内容(在本例中没有内容)。

The whole finite element model includes 5 nodes and 5 elements, and these element types are D. C. motor element, reduction gear element, beam element, crank element and buffer element.

有限元模型包括5个节点和5个单元，这些单元分别是直流电机单元、齿轮减速器单元、梁单元、曲柄单元和缓冲器单元。
