synchronous
🇺🇸 /sˈɪŋkɹʌnʌs/
🇬🇧 /ˈsɪŋkɹənəs/
表示多个事件在同一时间或同一节奏上进行;在计算机语境中,还可指一个操作必须等前一步完成后,后续工作才能继续。
💡 记忆钩子
把它想成几件事被同一只钟牢牢对齐:它们同时发生、按同一频率运行;在程序里,这种“对齐”进一步表现为调用者停在原地,等同一条执行线上的工作完成后再继续。
📖 中文释义
adj
-
core 同时发生;同频运行📖 指多个事件在同一时间发生,或多个周期性过程以相同频率运行,核心是它们被同一个时间节奏对齐。💡 常用结构是“同步的+名词”或“两个过程是同步的”,也可说某信号与另一个信号同步。它比一般的“同时”更强调时间安排、节奏或频率的一致,常用于技术、科学和较正式的说明。中文学习者容易把它误解成“完全相同”,但这里主要说时间关系相同。The two clocks are synchronous and show the same time.这两只钟是同步的,显示相同的时间。The dancers moved in synchronous steps.舞者们迈着同步的步子。
-
common 同步阻塞的📖 在计算机中,指一个操作开始后,调用它的程序或执行线必须停下来等待该操作完成,之后才能继续进行。它体现的是“按同一条时间线对齐”,而不是让任务在后台同时推进。💡 常见结构是“同步调用”“同步操作”或“同步地执行某任务”,也常与“异步”对比。它通常说明调用会阻塞当前执行线,因此不适合需要保持界面流畅或同时处理其他工作的场景。不要把“同步”误读成“多个任务同时运行”;这里的关键是调用者要等待完成。A synchronous request blocks the program until the server responds.同步请求会阻塞程序,直到服务器作出响应。

🌳 词源
源自古希腊语中表示“共同、一起”和“时间”的词根,后来经晚期拉丁语进入英语。
Borrowed from Late Latin synchronus, from Ancient Greek σύγχρονος (súnkhronos, “contemporaneous”), from σῠν- (sŭn-, “with, together”) + χρόνος (khrónos, “time”). By surface analysis, syn- + chron- + -ous = synchrony + -ous; however, all related words (e.g., synchronic, synchrony, synchronicity, diachronous, diachronic, diachrony, diachronicity) were coined later, either as back-formations from, or otherwise by analogy with the surface analysis of, synchronous.
