After integrating out the electron degrees of freedom, we derive the effective action describing the nuclear spins and the propagator for the spin wave.

将电子自由度积掉后，我们得到了描述核自旋的有效作用量以及核自旋的自旋波传播子。

The core of the sun - where nuclear reactions produce neutrinos - apparently spins more slowly than the surface we see.

我们看到进行核反应产生中微子的太阳核心的自转速度明显比太阳表面慢。

Some physicists have conjectured that the two possible nuclear spins of P-31 make it ideal for use as the basis for solid-state quantum computing.

Nuclear experts also noted that North Korea could be facing similar technical difficulties as Iran in operating the equipment, which spins at supersonic speeds and can easily break apart or leak uranium gas if its parts aren't balanced and fortified with high-end metals.
