path integral的用法和樣例：
例句
- The quantum information can be taken from the classical description of physics by Feynman path integrals.
通過費曼路徑積分可以從物理學的經典描述中提取量子信息。 - On the other hand, the path integral over metrics with nontrivial topologies leads to correlation functions that decay to zero.
這樣隨著時間推移只有保留在拓撲平凡路徑積分上的完整物質信息將起作用。
