Papaya for instance contains an enzyme called papain which promotes the faster transit of food through the gut helping to shed the pounds .

例如，木瓜含有一种酶（木瓜蛋白酶）， 加快食物在肠道的消化速度帮助 减肥。

If less time could be spent accelerating the shuttle and the transit time of the shuttle through the shed could be reduced higher loom speeds could be obtained .

如果减少给梭子加速用的时间，而且 梭子穿过 梭 口的时间也能减少，织机便可以以较高的速度运转。
