我们提供了一个高精度的、相干消散的毫秒脉冲星(MSPS)偏振分布的大样本，频率在410到1414 MHz之间。这些数据包括对几颗脉冲星的第一次偏振观测，以及对其他脉冲星的第一次低频偏振轮廓。我们的观察结果支持了之前的观点，即MSP的脉冲形状和偏振比它们速度较慢的近亲更复杂。一个直接的结论是，为年轻脉冲星提出的基于偏振的分类方案在应用于毫秒脉冲星时只能有限地使用。
We present a large sample of high-precision, coherently dedispersed polarization profiles of millisecond pulsars (MSPs) at frequencies between 410 and 1414 MHz. These data include the first polarimetric observations of several of the pulsars and the first low-frequency polarization profiles for others. Our observations support previous suggestions that the pulse shapes and polarimetry of MSPs are more complex than those of their slower relatives. An immediate conclusion is that polarimetry-based classification schemes proposed for young pulsars are of only limited use when applied to millisecond pulsars.
