polarization transfer造句

For example, the polarization transfer is spontaneous after a homolysis chemical reaction.
When electron spin polarization deviates from its thermal equilibrium value, polarization transfers between electrons and nuclei can occur spontaneously through electron-nuclear cross relaxation and / or spin-state mixing among electrons and nuclei.
On the other hand, when the electron spin system is in a thermal equilibrium, the polarization transfer requires continuous microwave irradiation at a frequency close to the corresponding electron paramagnetic resonance ( EPR ) frequency.
It's difficult to find polarization transfer in a sentence. 用polarization transfer造句挺难的
