摘要
本文介绍了增强型 X 射线计时与极化测量任务（eXTP）的当前进展，该任务已于 2030 年获准发射。eXTP 是一项旨在极端物质密度、引力与磁场条件下研究基础物理学的空间科学任务。该任务旨在确定超核密度物质的方程状态、测量量子电动力学效应，并理解强引力场中物质的动力学。除了基础物理学研究外，eXTP 任务有望成为 2030 年代时域与多信使天文学的领先观测站，同时为多种银河系内外天体提供前所未有的观测质量。在简要介绍 eXTP 任务历史与科学目标概述后，本文综述了：1) 任务科学仪器的前沿技术、技术规格与预期性能；2) 完整的任务概况，涵盖 spacecraft 设计、运行能力与地面段基础设施。
