通过对流水线上操作人员在不同作业姿势下的疲劳分析，研究站姿、坐姿和站、坐交替三种姿势的疲劳时间阈值和劳动时间率。
By analyzing operator's fatigue states under different working posture on assembly line, studys the fatigue threshold and working time rate of standing posture, sitting posture and alternate posture.
因此，许多分析人士着眼于劳动生产率，通常来讲就是用总产出除以全部的劳动人口或者劳动时间来计算。
Most analysts focus on Labour productivity, which is usually calculated by dividing total output by the number of workers, or the number of hours worked.
利用直接劳动时间计算预先决定的预算率。
Calculate the predetermined overhead rate based on direct Labour hours.
未来几个月间，由于产出增速将高于劳动时间增速，因此，生产率将保持强劲增长，据此估算，劳动生产率的趋势增长率将在2%左右。
That strong pace should continue for a few months as output rises faster than hours, confirming that the underlying trend is around 2%.
