"在下文中" can be translated into English as "in the following text", "hereafter", or "below", depending on the context and tone. Here are some examples:
1、 In the following text, we will discuss the specific implementation steps.
在下文中，我们将讨论具体的实施步骤。
2、 Hereafter, all references to "the company" shall mean XYZ Corporation.
（此句中“hereafter”意为“此后；自今以后”，但若用于类似“在下文中提及的‘公司’均指XYZ公司”的语境，可传达类似含义，不过更自然的表达可能是“From now on”或“In the context that follows” ）更自然的对应表达：In the context that follows, all references to "the company" shall mean XYZ Corporation.
在下文中提及的“公司”均指XYZ公司。
3、 Please refer to the information below for further details.
（此句中“below”虽不完全等同于“在下文中”的所有语境，但在指代下文信息时可用；更贴近原意的可能是“Please refer to the following information” ）更准确的对应表达：Please refer to the following information for further details.
请参考下文信息以获取更多详情。
For most cases, especially when you want to explicitly refer to the content that comes next in a text, "in the following text" is a suitable and clear translation.
