或者，通过使用一个“下标数组”，您可以对具有特定下标的元素有选择地进行操作。

Or you can operate selectively only on elements with certain indices, by using an "index array".

RAND _ LOOKUP，随机查找函数，该函数根据作为查找表中下标的随机数从查找表中选择目标列的值。

RAND_LOOKUP, a random lookup function that selects a value for the destination column from a lookup table based on a random number as the subscript in the lookup table.

更常见的是用一个或一组值，例如一个索引寄存器或下标的值来寻找一个特定数据元素。

More generally, a value or set of values, such as an index register or a subscript, used to locate specific data.

The exception is right there. It's an index error, that is it's trying to do something going beyond the range of what this thing could deal with.

但他事实上抛出一个异常，异常就在这里，这是一个下标错误,它是试图去取超出范围的元素造成的。

So let's just think exactly what this means, and that means that if we take away function and we define it in terms of n, l and m sub l, what we're defining here is the complete description of an orbital.

让我们来考虑一下这是什么意思，这是说如果我们不考虑波函数,而是用ｎ，ｌ，ｍ下标ｌ来定义它，我们定义的,是一个轨道的完整描述。

If I don't show you any argument for v, it means v at time t and the subscript of 0 means t is 0.

如果我不对v做任何标志,那就表示t时刻的速度v,下标0表示的是t=0
