核火箭原理、发展及应用

人类在不懈地对浩瀚的宇宙进行着探索，而强劲的推力是人类探索宇宙的关键。化学火箭在人类宇宙探索活动中书写了一页又一页的华丽篇章，现今在人类新的探索使命下，出现了激光、太阳能、微波、核热能等新的推进技术。在这些技术中，核火箭推进无疑是人类继续探索太空最有希望的技术之一。对核火箭的原理、发展状况以及应用前景进行了介绍。

The fundamentals,developments and applications of nuclear rocket propulsion

The vast space is explored continuously by human being, and the strong thrust is of great importance. The chemical rocket has been used during the former exploration events. Today, some new propulsion technologies, such as laser, solar energy, microwave and nuclear thermal propulsion are presented. In these technologies, one of the most promising technologies for the future exploration to deep space may be Nuclear Thermal Rocket Propulsion. The fundamentals, developments and applications of Nuclear Thermal Rocket Propulsion will be discussed here.
