求翻译：当企业需要在旧派和新派管理科学之间找到某种平衡时，他们将面临一个真正的难题，尤其是在默契与其所进行的事物型活动和转换型活动均匀地混合在一起时，更是如此。是什么意思？

When companies need old school and new school when finding a balance between management science, they will face a real challenge, especially in a tacit understanding with the thing-activity and conversion type activities evenly mixed together, and even more so.
