Abstract

The recently discovered celestial sources of pulsed radio energy can be used to test general relativity, to study the solar corona, and to determine the earth's orbit and ephemeris time. The vector positions and transverse velocities of pulsars can be measured with radio interferometers; in combination with pulse-arrival-time data, the distance determination will yield the average interstellar electron density.

摘要

最近发现的射电脉冲能量天体源可用于检验广义相对论，研究太阳日冕，以及确定地球轨道和历书时。脉冲星的矢量位置和横向速度可用射电干涉仪测量；结合脉冲到达时间数据，可确定距离，从而得到平均星际电子密度。
