讨论了一种基于通过重新连接磁场线加速的相对论电子加热的球粒原始熔化的新机制。该机制不存在用于加热的碰撞的产生-湮灭问题。重联的基本要求是具有反转区域的行星际磁场。早期磁场是根据陨石的古地磁学和太阳自旋下降的要求推断出来的，而重新连接所依据的磁场反转是当前时代太阳风的共同属性。
A new mechanism for primordial melting of chondrules based upon heating by relativistic electrons accelerated by reconnecting magnetic field lines is discussed. This mechanism is free of the creation-annihilation problem of collisions used for heating. The basic requirements for reconnection are an interplanetary magnetic field with regions of reversals. An early mangetic field is inferred from the paleomagnetism of meteorites and the requirements of solar spin-down, while the field reversals upon which the reconnection is based are a common property of the present epoch solar wind.
