随着空间技术的发展,空间带电粒子的测量正迅速地向深度和广度发展。从近地空间的测量扩展到星际间的测量;被测粒子的能量已向高(几个GeV)、低(几+eV)端延伸;被测的粒子成分从电子、质子到Z≥30的重核;同位素丰度的测量已从氢扩大到硫;研究的领域也从宇宙线空间物理发展到宇宙线天文学。对带电粒子的成分、能谱、时间和空间变化,以及不同成分到达方向的测量,将为粒子的起源、加速和传播过程、寿命和动力学过程以及星际介质的性质提供信息;对同位素丰度的测量将提供源区核反应过程的性质等。
With the development of space technology, the measurement of space-charged particles is rapidly evolving to depth and breadth. From near-Earth space measurements extended to interstellar measurements; the measured particle energy has been high (a few GeV), low (a few + eV) end extension; measured particle composition from electrons and protons to Z ≥ 30 Heavy nuclei; isotope abundance measurements have expanded from hydrogen to sulfur; and research has also moved from cosmic ray space physics to cosmic ray astronomy. The measurement of the composition, energy spectrum, time and space, and direction of arrival of different components of charged particles will provide information on the origin, acceleration and propagation of particles, life and kinetic processes and the properties of interstellar media. For isotope abundance The measurement will provide the nature of the nuclear reaction process in the source zone.
