	The emplace members of <<ref_value>> return a typed reference to the underlying representation. For example, the call to <<ref_value_emplace_string,`value::emplace_string`>> in the previous example returns a <<ref_string,`string&`>>. This table shows the underlying type for each kind:	<<ref_value>> 的置入成员函数返回对底层表示形式的类型化引用。例如，前例中对 <<ref_value_emplace_string,`value::emplace_string`>> 的调用返回一个 <<ref_string,`string&`>> 。下表列出了每种 kind 对应的底层类型：</ref_string,`string&`></ref_value_emplace_string,`value::emplace_string`></ref_value>

	= `value` JSON documents are represented in memory as instances of <<ref_value>>: a {req_Regular} type which satisfies {req_DefaultConstructible}, {req_CopyConstructible}, {req_CopyAssignable}, {req_MoveConstructible}, {req_MoveAssignable}, and many of the requirements of allocator-aware containers. It is implemented as a https://en.wikipedia.org/wiki/Tagged_union[__variant__] internally, and can dynamically store any of the six defined JSON value types:	= `value` JSON文档在内存中表示为<<ref_value>>的实例：一种{req_Regular}类型，满足{req_DefaultConstructible}、{req_CopyConstructible}、{req_CopyAssignable}、{req_MoveConstructible}、{req_MoveAssignable}以及许多分配器感知容器的要求。它在内部实现为一个https://en.wikipedia.org/wiki/Tagged_union[__variant__]（变体），并且可以动态存储六种已定义的JSON值类型中的任意一种：</ref_value>
	string: A sequence of zero or more Unicode characters,	字符串：由零个或多个Unicode字符组成的序列，
	array: An ordered list of values, like {std_vector}.	数组：值的有序列表，类似于{std_vector}。
	object: A collection of name/value pairs, also known as an	对象：名称/值对的集合，也称为
	https://en.wikipedia.org/wiki/Associative_array[__associative array__].	https://en.wikipedia.org/wiki/Associative_array[__关联数组__]。
	Functions like <<ref_value_if_object,`value::if_object`>> actually return a pointer to the object if the value is an object, otherwise they return null. This allows them to be used both in boolean contexts as above, and in assignments or conditional expressions to capture the value of the pointer:	诸如 <<ref_value_if_object,`value::if_object`>> 的函数在值为对象时返回指向该对象的指针，否则返回空指针。这使得它们既可用于上述的布尔上下文，也可用于赋值或条件表达式中，以捕获指针的值：</ref_value_if_object,`value::if_object`>
