For functions and constants, if the current namespace does not contain that function or constant, PHP's fallback mechanism will fall back to the standard PHP function.
对于函数和常量,如果当前的名称空间不包含这个函数或常量,PHP的后退机制会后退到标准的php函数。
Once you have made the changes to the XML document in memory, a single function call writes it back out to the configuration file.
在对内存中的XML文档完成了相应的修改之后,只需使用一个函数调用就可以将其写回到对应的配置文件中。
The activation record isn't needed anymore, so we are going to cut it out and redirect the tail-called function back to the function that called us.
再也不需要活动记录(activation record),所以我们将删掉它,并将尾部调用的函数重定向返回到调用我们的函数。
It's totally legit to cull a function, get back a value, do nothing with it other than compare it to another value.
挑选一个函数是完全合法的,返回一个值,用它来做些事情而不是用它与其它的值比较。
So, that's probability density, but in terms of thinking about it in terms of actual solutions to the wave function, let's take a little bit of a step back here.
这就是概率密度,但作为,把它当成是,波函数的解,让我们先倒回来一点。
You try to design actually I'm going to come back to that in a second. It's like you're trying to use a hash function that spread things out pretty evenly. But the places you store into in those lists may have to themselves have a small list in there, and when you go to check something, you may have to do a linear search through the elements in that list.
你尝试着去设计,实际上过会儿我会回头讲解这个问题,类似于你需要用一个哈希函数,非常平均的将物体分发出去,但是在列表中你数据,映射到的地方可能会有自己的一小段列表,当你回头查找数据的时候,你可能需要在那一小段列表中做线性查找。
