我的看法,断句应该是:
this assumption is (for example) satisfied, if members belongs to a single association, and are differentiated in a direction (which is) orthogonal to (that of) platform differentiation.
"orthogonal to...." 是解释direction的
括号里的是修饰词,断句时可跳过
不知道具体说的什么专业内容。。。试着翻译:
如果成员(分子)属于某一单一组合,并且成员间的分化与平台分化成正交,那么这个假设就可满足。
