平直空间 meaning in English
flat 2
Examples
- When this tensor vanishes, the space is calleda flat .
当这一张量为零时，空间叫做平直空间。 - Although derrick ' s theorem forbids solitons in more than 1 + 1 dimensions , gopakumar , minwalla and strominger found that soliton solution in ( 2 + 1 ) noncommutative scalar field theory can be exactly given in terms of projection operators
尽管derrick定理说明在超过1十1维普通空间标量场论中孤子解是不可能存在的， gop砍umar 、 headrick和spr耐lin发现在( 2 + 1 )维平直空间非对易标量场论的孤子解是存在的。
