By combining mathematical models and the underlying physical systems, the concept of blown-ups is formally introduced for the study of whole evolutions.

通过把数学模型与其潜在的物理系统进行结合，正式地引入了在整体进化研究中的溃变概念。

True, we have mathematical models that approximate the behavior of many physical systems, and in some cases (like quantum mechanics) it does so with extremely high precision.
