微小碎片超高速撞击太阳电池阵的研究进展

概述了空间环境下微小碎片超高速撞击太阳电池阵的影响，不仅对太阳电池阵造成机械损伤，还诱发持久电弧放电，对其寿命和可靠性形成威胁。详细介绍了日本、欧洲、中国等一些国家在本领域的研究状态、研究特点，对实验中涉及的对瞬态等离子体诊断和等离子体诱发二次放电进行了重点介绍。提出了加快我国空间碎片超高速撞击特性研究的建议，这也是做好卫星太阳电池阵防护的重要途径。

RESEARCH PROGRESS OF THE SPACE SMALL DEBRIS HYPERVELOCITY IMPACT ON SOLAR CELLS

The infections on solar array by small space-debris hypervelocity in space environment are summarized. It causes not only mechanical damage but also permanent sustained arc （ PSA ） to solar array. And it also makes threats to solar array life time and reliability. The research progress is introduced in detail in Japan, Europe and China. And the key method is both diagnose instantaneous plasma and measures the second discharge by plasma induced. The research of hyperveloeity characteristic about space-debris impact on solar array is suggested in order to protect the satellite solar array.
