Cannily, the Corning researchers simply took the arithmetic mean of the oxide compositions and created a winning combination, known as "1737 glass", with exactly the right density.

康宁公司精明的研究人员们仅采用了算术平均法来处理氧化物，便成功地制造出一种称为“1737玻璃”的合成物，该玻璃的密度正好符合要求。

You are shrunk to the height of a nickel and your mass is proportionally reduced so as to maintain your original density. You are then thrown into an empty glass blender.

假设你被缩小到一枚硬币那么大，你的质量也同比例缩小以保持你的密度不变。

The density of Saturn is so low that if you were to put it in a giant glass of water it would float.

土星的密度是如此之低，以至于如果你能把放在一个巨大的装有水的玻璃杯里，它会漂浮在水面上。

The company has tweaked the chemical and atomic composition of the raw materials of the glass, which in turn has increased its density -- making it much more scratch and dent resistant than last years model.

The wall of glass on one side of the library, combined with its geographic exposition and the density of students in the small facilities turned it into a sauna for half the day during the spring months (which were also the exam months, when the libraries were most in demand).
