求翻译：通过将酸洗和提杂的温度从20-25℃降至0-5℃，有效抑制了闭环产物（CPPI）的生成，从而将该步收率从原来的约60%大幅提高至80%以上是什么意思？

Pickling and mention the complicated temperature dropped to 0-5 ° C from 20-25 ° C, effectively inhibited the formation of closed-loop product (cppi) to the step yield a substantial increase from about 60% to more than 80%

It will be adopted by reference and the temperature from 20 - 25 °C drops to 0 - 5 °C, effectively suppresses the closed-loop product (CPPI) generation, and thus will be the further from the original rates about 60 per cent increase to more than 80 per cent

Through and proposes the acid pickling the mixed temperature from 20-25℃ to fall to 0-5℃, has effectively suppressed the closed loop product (CPPI) production, thus this step receives original rate from 60% largely enhances approximately to 80% above

By pickling, and noise temperature from 20-25 ° c down to six degrees Celsius, inhibit a closed-loop product (CPPI) generation, so that the sharp increase in yield from about 60% to over 80%
