在牡蛎季节中的牡蛎壳，在龙虾季节中的龙虾壳，在所有季节中的破碎的陶器和枯萎的卷心菜叶，像小坟般一堆一堆地侵占了铁路线的路堤。

Little tumuli of oyster shells in the oyster season, and of lobster shells in the lobster season, and of broken crockery and faded cabbage leaves in all seasons, encroached upon its high places.

So, let's take a look at one of these rows in more detail to think about why this might be happening, and it turns out the reason that these glitches occur are because the sub shell structure predominates in certain instances, and that's where these glitches take place.

那么，让我们仔细地看一看其中一行,想一想为什么会这样，结果是这些小偏差的出现,是因为在一定情况下,亚壳层结构会产生重要影响，这正发生在小偏差出现的地方。

So, what we can do to actually get a probability instead of a probability density that we're talking about is to take the wave function squared, which we know is probability density, and multiply it by the volume of that very, very thin spherical shell that we're talking about at distance r.

我们能得到一个概率,而不是概率密度的方法,就是取波函数的平方，也就是概率密度，然后把它乘以一个在ｒ处的,非常非常小的,壳层体积。
