求翻译：The brilliant white polar ice caps of Mars have long played a role in our understanding of the planet. Interpreted as early as the 1790s by William Herschel as arctic ice fields (like those of Earth), they inspired him to argue that Mars was Earth-like. For about a century, from the 1860s to the 1960s, scientists argue是什么意思？ 待解决

明亮的白色火星极地冰盖长在我们这个星球的了解发挥了重要作用。解释，早在18世纪90年代由威廉·赫歇尔的北极冰原（如地球），他们启发了他争辩说，火星是地球类似的。大约一个世纪，从19世纪60年代到20世纪60年代，科学家们争论什么样的冰在那里。第一个假设是冷冻水，地球上。后来的研究者开始认识到它可能被冻结的二氧化碳就是我们所说的干冰，因为二氧化碳是主要的气体在火星大气中和极地的冬天不够冷冻结固体。
