but I'm not sure everybody understood it.

但不是所有人都能明白
John, do you have an idea?

你觉得呢
The top one seems to be more dense than the bottom one.

上面的电子密度好像比下面那个大
One, two, three, four;

一二三四
one, two, three four five.

一二三四五
That's true, it is a little more dense.

确实是密度要大些
That kind of thing could be experimental error,

这种东西应该是测量误差
because even though this was done so precisely,

因为就算这是很精确地做出来的
you're subtracting two numbers that are very large,

但扣除的两个数值实在很大
so that any error you make in the experimental one,

所以任何测量上的误差
or in positioning things for the theoretical position of the atoms,

或者在理论上给原子定位的时候的误差
any error you make will really be amplified in a map like this.

在最终的成图上都会被这样放大
