摘　　要：利用产生算符和消灭算符构造出费米系统的自旋阶梯算符。针对粒子数不变的情形,所构造的阶梯算符能对自旋角动量的本征值和对应的本征态起升降作用。讨论了费米子系统的自旋与强磁场相互作用能量本征态完备集的确定方法。Work out Fermi System' s spin step operator by producing and diminishing operator. According to thesituation of unchangeable particle's number, the constructed step operator can serve as rising and falling to spin angularmomentum's eigen values and vector. And discuss the dertermination of Fermi Particle System's spin and strong magneticfield's complete of interactive cooperation energy eigen vectors.
