Quantum Transition in the NMR System in the Case of Producing the A-A Phase

该文研究在产生A -A相的条件下 ,核磁共振系统的量子跃迁 .结果表明 :对于一个大小给定的旋转磁场 ,其角速度只能在为一系列离散的、依赖于自然数n(n =2 ,3 ,4,… )的值时 ,才能产生A -A相 ;系统在演变过程中 ,存在量子跃迁 ,随n的增大 。

This paper discusses the quantum transition in the nuclear magnetic resonance (NMR) system in the case of producing the A-A phase, and concludes that the A-A phase can be produced only when the angle speed is one of discrete value depending on natural number n(n=2,3,4,...) for a revolving magnetic field when its size is given; There is quantum transition when the system evolves and transition probability will decrease when n increases.
