求翻译：关键路径上的每一道工序的时间分别为：A工序的时间为20天，B工序的时间为20天，D工序的时间为40天，G工序的时间为50天，H工序的时间为30天，J工序的时间为40天，K工序的时间为30天，M工序的时间为20天。是什么意思？

The time of every process on the critical path are as follows: a process time of 20 days, b process time of 20 days, d process time of 40 days, g process time of 50 days, h process time is 30 j process time of 40 days, k process time of 30 days, m process time of 20 days.

On the critical path of each of the processes of the time were as follows: A operation time is 20 days, and the time the operation B for 20 days, D operation for 40 days, the time the operation G for 50 days, the time the operation H for 30 days, J operation for 40 days, K operation time is 30 days,

In the essential way each working procedure time respectively is: The A working procedure time is 20 days, the B working procedure time is 20 days, the D working procedure time is 40 days, the G working procedure time is 50 days, the H working procedure time is 30 days, the J working procedure time

Key path Shang of each road process of time respectively for:-a process of time for 20 days, b process of time for 20 days, d process of time for 40 days, g process of time for 50 days, h process of time for 30 days, j process of time for 40 days, k process of time for 30 days, m process of time for
