First, we probe into the crafts of rotor spinning and ring spinning and combining the characteristic of the fiber to spin.

结合天然彩棉纤维本身的特点，在纺纱过程中分别运用气流纺纱和传统的环锭纺技术进行了纺纱工艺的探索。

For a ring of two spins, the entanglement between the two spin particles can be created and is a periodic function of time when the external magnetic field is greater than a critical value.

在圆环中只有两个自旋粒子时，外加磁场大于某个阈值时，一对自旋粒子之间才能产生纠缠，而且纠缠是时间的周期性函数。
