The Moon's mean density is much lower than that of Earth but is about the same as that of Earth's mantle.
月球的平均密度比地球低得多,但与地球的地幔密度大致相同。
So you mean the density of the wood in the Cremonese violins is, is more uniform?
你是说,克雷莫纳小提琴的木头密度更均匀吗?
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。
So what is actually going to matter is how closely that electron can penetrate to the nucleus, and what I mean by penetrate to the nucleus is is there probability density a decent amount that's very close to the nucleus.
所以实际上有关系的是,电子可以穿越至原子核有多近,我所指的穿越至原子核是,这里有一定数量的概率密度,可以距离原子核非常近。
And when we look at this, it's actually split by what's called a nodal plane, which is pointed out in light orange here on this picture, but what we just mean is that there is this whole plane that separates the two lobes where there is absolutely no electron density.
我们来看这里,实际上它被一个节面分开,在这图里用淡黄色表示,这意味着这个分开,两个叶瓣的平面上,是完全没有电子密度的。
