(三)decrease n times/n--fold (14) decrease by n times(15) decrease by a factor of n(16) 以上三式均译为:减少到1/n[或:减少(n-1)/n]。 decrease常被reduce, shorten, go/slow down等词替代。 Eg. Switching time of the new-type transistor is shortened 3 times. 新型晶体管的开关时间缩短了1/3(即缩短到2/3)。 Eg. When the voltage is stepped up by ten times, the strength of the current is stepped down by ten times. 电压升高9倍,电流强度便降低9/10(即90%)。Eg. The equipment reduced the error probability by a factor of 5. 该设备误差概率降低了4/5。
