-which means `heap_end_ptr` or `_end` + `512`(`0x200h`). The last check is whether `heap_end` is greater than `stack_end`. If it is then `stack_end` is assigned to `heap_end` to make them equal.
 
-Now the heap is initialized and we can use it using the `GET_HEAP` method. We will see how it is used, how to use it and how the it is implemented in the next posts.
+接下来代码判断`heap_end`是否大于`stack_end`，如果条件成立，将`stack_end`设置成`heap_end`（这么做是因为在大部分系统中全局堆和堆栈是相邻的）。
+
+到这里位置，全局堆就被正确初始化了。在全局堆被初始化之后，我们就可以使用`GET_HEAP`方法。至于这个函数的实现和使用，我们将在后续的章节中看到。
