据国外媒体报道,科学家们对肆意浪费氦这种稀有且不可再生资源来给气球充气的行为敲响了警钟:作为医疗成像、火箭引擎以及监控设备等科技的基本资源,氦显然有比用来灌气球更有价值的作用。可是地球上大多数的氦却就这么被我们给轻易用气球放到大气层去,最后消失不见了。美国宾夕法尼亚州立大学的埃文皮尤物理学教授陈豪解 According to foreign media reports, scientists are sorely beating the wanton waste of helium, a rare and nonrenewable resource, to inflate a balloon: Helium, apparently as a fundamental resource for technology such as medical imaging, rocket engines and surveillance equipment, Balloon more valuable role. However, most of the earth's helium is so easily we can use the balloon to the atmosphere, and finally disappeared. Chen Hsien-Xie, professor of physics at Evan Piyu, Penn State University, USA
