I don ' t know who is doing that . general coordinate invariance is again a symmetry ( i do think it is possible to derive it from quantum mechanics 也有的想在广义相对论的基础上重建量子力学（后者大概是弯曲时空中的量子力学或量子场论吧？ ） 。
This was not only a brand - new understanding of controversy , but also a good illustrate to how our party became the representative of advanced culture 这既是对这场论争的一个全新的认识，亦是对我党是如何成为先进文化的代表的一个最好说明。
One would like to know to which extent properties of quantum field theories on commutative spaces also arise in quantum field theories on noncommutative space 我们总是想知道对易空间的量子场论的特点在多大程度上同样适用于非对易空间的量子场论。
In this paper , we mainly take two dimensional non - commutative chiral qcd2 model as an exameple to discuss the chiral anomaly in noncommutative field theory 在这些问题中，量子场论中的反常问题引起了人们的广泛兴趣。在这一方面，我们做了如下工作。
The study on unifying several kinds of force is the “ unification field theory ” , which was put forward by albert einstein at the beginning of the 20th century 研究将几种力统一起来的理论叫做“统一场论” ，它是由阿尔伯特?爱因斯坦于20世纪初提出来的。
