八边形

It was wholly in the lower ice, but close against the upper, and was flattish, or perhaps slightly lenticular, with a rounded edge, a quarter of an inch deep by four inches in diameter; and I was surprised to find that directly under the bubble the ice was melted with great regularity in the form of a saucer reversed, to the height of five eighths of an inch in the middle, leaving a thin partition there between the water and the bubble, hardly an eighth of an inch thick; and in many places the small bubbles in this partition had burst out downward,and probably there was no ice at all under the largest bubbles,which were a foot in diameter.

在气泡之下和周围已经结了一层新的冰，所以气泡是在两片冰的中间；它全部是在下层中间的，却又贴近上层，扁平的，也许有点像扁豆形，圆边，深四分之一英寸，直径四英寸；我惊奇地发现，就在气泡的下面，冰溶化得很有规则，像一只倒置的茶托，在中央八分之五英寸的高度，水和气泡之间有着一个薄薄的分界线，薄得还不到一英寸的八分之一，在许多地方，这分界线中的小气泡向下爆裂，也许在最大的直径一英尺的气泡底下完全是没有冰的。
