	The default memory resource uses the global `operator new` and `operator delete` to allocate memory. This resource is not reference counted and has a non-trivial deallocate function. All default-constructed <<ref_storage_ptr>> objects reference the same memory resource:	默认内存资源使用全局 `operator new` 和 `operator delete` 来进行内存分配。该资源不采用引用计数，且其 deallocate 函数是非平凡的。所有默认构造的 <<ref_storage_ptr>> 对象均引用同一个内存资源：</ref_storage_ptr>
	Default-constructed library containers use the default memory resource:	默认构造的库容器使用默认内存资源：
	The default memory resource is well suited for general usage. It offers reasonable performance for parsing, and conservative memory usage for modification of the contents of containers.	默认内存资源适用于一般用途。它在解析时提供合理的性能，在修改容器内容时则具有保守的内存使用特性。
	This memory resource is not guaranteed to be the same as the result of `boost::container::pmr::get_default_resource`. It also cannot be changed with `boost::container::pmr::set_default_resource`.	该内存资源不保证与 `boost::container::pmr::get_default_resource` 的返回结果相同，也无法通过 `boost::container::pmr::set_default_resource` 进行更改。
	Consider the pattern of memory allocation during parsing: when an array, object, or string is encountered the parser accumulates elements in its temporary storage area. When all of the elements are known, a single memory allocation is requested from the resource when constructing the value. Thus, parsing only allocates and constructs containers at their final size. Memory is not reallocated; that is, a memory buffer never needs to grow by allocating a new larger buffer and deallocating the previous buffer.	考虑解析过程中的内存分配模式：当遇到数组、对象或字符串时，解析器会将其元素累积在临时存储区中。当所有元素都已知后，在构造值时会向内存资源发起一次内存分配请求。因此，解析过程仅在容器最终大小确定时进行一次分配和构造，不会发生内存重分配；也就是说，内存缓冲区无需通过分配更大的新缓冲区并释放旧缓冲区的方式来扩容。
	The <<ref_monotonic_resource>> optimizes this memory allocation pattern by allocating increasingly large blocks of global memory internally and parceling those blocks out in smaller pieces to fulfill allocation requests. It has a trivial deallocate function. The monotonic resource does not actually deallocate memory until the resource is destroyed. Thus, it is ideally suited for the use-case where JSON is parsed, and the resulting value is then inspected but not modified.	<<ref_monotonic_resource>> 通过在内部分配逐渐增大的全局内存块，并将这些块切分为更小的部分以满足分配请求，从而优化了该内存分配模式。它具有平凡的 deallocate 函数，实际上不会释放内存，直到该资源被销毁。因此，它非常适合用于解析 JSON 后仅检查结果值而不对其进行修改的场景。</ref_monotonic_resource>
	The resource to use when constructing values may be specified in calls to <<ref_parse>> as shown here:	在调用 <<ref_parse>> 时，可按如下方式指定构造值所使用的内存资源：</ref_parse>
	Or, to parse into a value with shared ownership of the memory resource:	或者，可按如下方式解析到一个对内存资源具有共享所有权的值：
