求翻译：在425℃、10MPa和10000h-1的条件下，测得用柠檬酸处理的钴前驱体所得催化剂活性是未处理的150%，柠檬酸处理前驱体使催化剂活性得到明显提高。是什么意思？

425 ℃, 10mpa and 10000h-1 of the conditions, the measured starting a citric acid treatment of the cobalt precursor obtained catalyst activity is 150% of the unprocessed precursor of citric acid treatment has been markedly enhanced the activity of the catalyst.

At 10, 425 °C MPa and 10,000 H-1, measured under the conditions used citric acid treatment of the cobalt catalyst precursor activity is derived from body is not processing the 150 per cent, and citric acid precursor processing makes catalyst activity is significantly improved.

In 425℃, 10MPa and under the 10000h-1 condition, obtains with the lemon acid treatment cobalt forerunner body obtained catalyst activeness raw sewage 150%, the lemon acid treatment forerunner body enable the catalyst activeness to obtain the distinct enhancement.

At 425 ℃ under 10MPa and 10000h-1 conditions, the measured using cobalt catalysts derived from precursor activity of citric acid is 150% is not processed, citric acid precursor catalyst activity to be markedly improved.
