在林克最近的一篇论文中，他指出，中子星星核心由中子超流体和质子II型超导体的混合物组成的标准图像与孤立恒星中长周期进动的观测结果不一致。在下文中，我们将证明，当质子涡旋的结构发生强烈变化时，对相互作用的两组分超流体（由中子和质子库珀对组成）进行适当的处理，可能会极大地改变标准图像，从而产生I型超导体。在这种情况下，磁场被从中子星星的超导区域中排出，导致超导物质和正常物质交替共存时的中间态的形成。
In a recent paper by Link, it was pointed out that the standard picture of the neutron star core composed of a mixture of a neutron superfluid and a proton type-II superconductor is inconsistent with observations of a long period precession in isolated pulsars. In the following we will show that an appropriate treatment of the interacting two-component superfluid (made of neutron and proton Cooper pairs), when the structure of proton vortices is strongly modified, may dramatically change the standard picture, resulting in a type-I superconductor. In this case the magnetic field is expelled from the superconducting regions of the neutron star, leading to the formation of the intermediate state when alternating domains of superconducting matter and normal matter coexist.
