摘要
利用180颗脉冲星的法拉第旋转数据，详细研究了银河系经度40◦< l < 70◦方向的磁场，包括人马座旋臂区域。银河系北半球的磁场是指向太阳的，而南半球的磁场是指向太阳的。我们提出人马座旋臂主要位于银面北面，而银面下方方向相反的磁场是银河系南半球的晕场。
Magnetic Field in some Selected Directions of the Galaxy: Sagittarius Spiral Arm
Faraday rotation data on 180 pulsars are used in a detail study of the magnetic field in the direction of galactic longitude 40◦ < l < 70◦, including the Sagittarius spiral arm region. The highly regular magnetic field in northern hemisphere of galaxy is directed to the Sun, when the magnetic field of southern hemisphere is directed from the Sun. We propose that the Sagittarius spiral arm lies mainly to the north of the Galactic plane, while the magnetic field with opposite direction below this plane is the field of the halo of the southern hemisphere of the Galaxy.
