是Professionalisation还是Professionalization?

两个在百度中都能查到。
考研中的句子是： But specialization was only one of a series of related developments in science affecting the process of communication. Another was the growing professionalisation of scientific activity.

professionalisation被word给标红了，我查字典是Professionalization，到底哪个正确？

都正确。
它俩的关系就像 color 和 colour 一样。

有些事情别人帮不了你，还是得自己拿主意。
