That effort will be bootless.(那種努力將是無益的。)

In the absence of exact data, these discussions are bootless.(由于缺乏確切的資料，這些討論是徒勞的。)

To erase the bootless power dissipation of the redundant leap of the clock, this paper proposes the RTL design of double edge triggered counter using parallelism and pipeline technique.(該文從消除時鐘信號冗余跳變而致的無效功耗的要求出發，提出了應用并行技術和流水線技術，實現基于RTL級的雙邊沿觸發計數器的設計。)

And abaft every bootless man, there are two.(每個不勝利男人的背地，都有兩個。)
