推荐答案

短跳跃（和邻近的呼叫）是跳跃卫生组织目标是相同的模块中（他们是intramodular，但它有可能获得某些黑客intermodular变体） ，它们是最常见的多达127个字节相对位移（它们改变执行向前或向后从指令的地址的流动），但也有16位的变体提供的32k字节。你并不需要担心它了，它真的superfluos信息，但英特尔开发者手册（卷2a和2b，特别是2A）将覆盖血淋淋的细节

Short jumps (and near calls) are jumps whos target is in the same module(they are intramodular, however it is possible to get intermodular variants from certain hacks), they are most commonly up to 127 bytes of relative displacement(they change the flow of execution forward or backward from the address of the instruction), however there are 16bit variants offering 32k bytes. You don't really need to worry about it much, its really superfluos information, but the intel developer manuals(volumes 2a and 2b, specifically 2a) will cover the gory details
