adj.省工的；節(jié)省勞力的；減輕勞動(dòng)的

=labour-saving(英).

The increase in their profits is due partly to their steady production of labor saving devices. 他們利潤(rùn)增長(zhǎng)的部分原因是由于源源不斷生產(chǎn)出節(jié)省勞力的器具。

What aids there were to lighten labor were immemorial, like the mill, which was already ancient in Chaucer's time. 那些幫助減輕勞動(dòng)的機(jī)械都不知從哪個(gè)年代就有了，比如磨坊，在喬叟的時(shí)代就已經(jīng)是古老的了，而工業(yè)革命就是從這些機(jī)械開(kāi)始的。
