原声例句
TED-Ed（视频版） While the storms that reach us are generally harmless to humans, the high-energy particles falling into the atmosphere create secondary magnetic fields, which in turn generate rogue currents that short-circuit electrical equipment. 虽然到达我们的风暴通常对人类无害，但落入大气层的高能粒子会产生二次磁场，进而产生会使电气设备短路的流氓电流。

Primary field（重定向自Secondary field）
In theoretical physics, a primary field, also called a primary operator, or simply a primary, is a local operator in a conformal field theory which is annihilated by the part of the conformal algebra consisting of the lowering generators. From the representation theory point of view, a primary is the lowest dimension operator in a given representation of the conformal algebra. All other operators in a representation are called descendants; they can be obtained by acting on the primary with the raising generators. |
