Journalist:In physics journals, the number of articles reporting the results of experiments involving particle accelerators was lower last year than it had been in previous year. Several of the particle accelerators at major research institutions were out of service the year before last for repairs ,so it is likely that the low number of articles was due to the decline in availability of particle accelerators .

Can you help me tranlate it to Chinese.thanks.

记者说：在物理期刊中，去年报道有关粒子加速器实验结果的文章数量少于往年。一些在主要研究机构的粒子加速器在前年停止工作用于维修，所以低的文章数量很可能是可以使用的粒子加速器减少造成的。

I hope it's clear enough.
