	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>

	If the <<ref_kind>> of a <<ref_value>> is known, functions such as <<ref_value_as_bool,`value::as_bool`>> or <<ref_value_as_string,`value::as_string`>> may be used to obtain a reference to the underlying representation without changing the existing value:	如果已知 <<ref_value>> 的 <<ref_kind>>，可使用诸如 <<ref_value_as_bool,`value::as_bool`>> 或 <<ref_value_as_string,`value::as_string`>> 等函数，在不改变现有值的情况下获取对底层表示的引用：</ref_value_as_string,`value::as_string`></ref_value_as_bool,`value::as_bool`></ref_kind></ref_value>
	However, as shown above these functions throw an exception if the kind in the <<ref_value>> does not match the kind denoted by the function signature. This can be used as a concise form of validation: access values as if they were the right type, but handle the resulting exception indicating if the schema of the JSON is not valid.	然而，如上所示，如果 <<ref_value>> 中的实际类型与函数签名所指定的类型不匹配，这些函数会抛出异常。这一行为可作为一种简洁的验证形式：以预期类型直接访问值，若 JSON 结构无效，则通过捕获异常进行处理。</ref_value>
	We can query a value for its underlying representation of a particular kind in a way that does not throw exceptions by requesting a pointer which may be null, instead of a reference. Here we use <<ref_value_if_string,`value::if_string`>> to conditionally perform an assignment without using exceptions:	我们可以通过请求一个可能为空的指针（而非引用）来查询值中特定种类的底层表示形式，而不会抛出异常。这里我们使用 <<ref_value_if_string,`value::if_string`>> 来条件执行赋值操作，而无需使用异常：</ref_value_if_string,`value::if_string`>
	Functions returning {ref_result} allow you to use both approaches:	返回 {ref_result} 的函数允许您同时使用上述两种方式：
	When a <<ref_value>> is formatted to a {std_ostream}, the result is serialized JSON as if by calling <<ref_serialize>>.	当将 <<ref_value>> 输出到 {std_ostream} 时，其结果等同于调用 <<ref_serialize>> 所生成的序列化 JSON。</ref_serialize></ref_value>
