Read the following paragraph carefully and then translate it into Chinese.
Physics, as well as pure mathematics, has supplied material for the philosophy of logical analysis. This has occurred especially through the theory of relativity and quantum mechanics（量子力学）.What is important to the philosopher in the theory of relativity is the substitution of space-time for space and time. Common sense thinks of the physical world as composed of “things” which persist through a certain period of time and move in space. Philosophy and physics developed the notion of “thing” into that of “material substance,” and thought of material substance as consisting of particles, each very small, and each persisting throughout all time. Einstein substituted events（事素）for particles; each event had to each other a relation called “interval,” which could be analyzed in various ways into a time element and a space-element. The choice between these various ways was arbitrary（任意的）, and no one of them was theoretically preferable to any other.
