首先，在太空微重力环境下，金属熔池和液滴成形控制难度极大，如同“用勺子盛太空中的水”，稍有不慎便会“洒落”。此外，这次实验无人工干预，完全依靠设备自主运行。为此，我和团队成员研发了高精度自适应闭环控制系统，通过多项关键技术攻关，实现了对熔融金属沉积与凝固过程的稳定控制。
Cornman arrived in Colorado just as the airlines were confronting a series of mysterious crashes. On June 24, 1975, an Eastern Airlines plane was blown to the ground half a mile short of its runway in New York.
