broaly speaking和generally speaking这两个意思是一样的吗?

第一个应为 broadly speaking 固定词组,一般来说,总的来说
Broadly speaking,there are two ways of storingelectrical energy in a chemical system.
一般来说,在化学系统中有两种储存电能的方法.
Broadly speaking there are two categories of softwaremaking organisations.
总的来说,存在于两类软件开发组织.
generally speaking = broadly speaking
是固定词组,无需分辨什么磁性,真要说的话是动词的现在分词
