Thus，a regularity for which there are general theoretical grounds will be more readily called a natural law than an empirical regularity that cannot be subsumed under more general laws or theories.
结构分析：句子的框架是a regularitywill be more readily called a natural law than an empirical regularity。介词for加关系代词which引导定语从句修饰a regularity。an empirical regularity后又有定语从句that cannot be subsumed under more general laws or theories修饰。grounds意为根据，理由subsume意为把归入，纳入。
译文：因此，与一条不能被归入更普遍的法则或理论而是基于经验的规律相比，一条具有普遍理论依据支持的规律很可能被认可为一条自然法则。
