基本解释

It is bounded above by a road that overhang it and below by a path.

It says that function, f of x, is bounded above here's an upper limit on it, that this grows no faster than quadratic in n, n squared.
這意味著這個方法f是有上限的,這個方法增長的速度,不會比括號內的n*n快。
When it is used, a job that never self- suspend is blocked at most once, and the duration of blocking is bounded from above by the maximum execution time of critical sections of lower - priority jobs.
使用該協議，一個作業不可能掛起自己，其至多被優先級低的作業阻塞一次，且阻塞時間僅爲一個臨界區的執行時間。
