研究了中子涡旋的运动和钉扎，并参考了超流分量，其弛豫给出了PSR 0355 + 54和0833 {-} 45观测到的角速度时间导数的大的不连续性。在高温下，在脉冲星生命的早期，涡旋不是被钉扎的，而是与超流体几乎精确地共转。证据的平衡表明，涡旋和超流体的共转，这对解释定时噪声和估计内部温度有影响，在脉冲星的整个生命周期中持续存在。参考文献18篇。
The movement and pinning of neutron vortices has been studied with reference to the superfluid component whose relaxation gives the large discontinuities in angular velocity time-derivative observed for PSR 0355 + 54 and 0833 {minus} 45. At high temperatures, early in the life of a pulsar, the vortices are not pinned but move in almost exact corotation with the superfluid. The balance of evidence indicates that corotation of vortices and superfluid, which has consequences for the interpretation of timing noise and the estimation of internal temperatures, persists throughout the life of a pulsar. 18 refs.
