求翻译：将所选定的关键工作的持续时间压缩至最短，并重新确定计算工期和关键线路;当计算工期仍超过要求工期时，则重复以上步骤，直至计算工期满足要求工期或计算工期已不能再缩短为止。是什么意思？

Duration of the selected work of compression to a minimum, and to redefine the calculation of the duration and critical path; calculate the duration still exceeds the requirements of the duration, repeat the above steps, until the calculation of the duration to meet the requirements of the duration

Will the selected key to the duration of the compression to the shortest, and re-establish computing project and key line; when the calculation period is still more than that, when finished, repeat the above steps until you calculate deadlines deadlines or meet the required deadlines can no longer b

Designated key work duration compression to shortest, and determines the computation time limit for a project and the essential line; When the computation time limit for a project still surpassed the request time limit for a project above, then duplicated the step, until the computation time limit f

Will be compressed to the shortest possible duration of selected key work, and then determine the calculation of the duration and the critical path when calculating duration still exceeds the duration is required, repeat the above steps until the calculated duration meet the requirements further sho
