把扩散模型的"预测噪声"换成"预测物理反演位移场"，并用木材纤维微结构与应力扩散耦合构造可计算的正向形变模型——这套"物理正向模拟+逐步反演"的思路可直接迁移到其他非刚性形变复原任务（褶皱文档、弯曲织物、软体形变）。

由模型翻译 · 术语统一 · 请对照原文核对关键结论竹简是记录古代东亚文明的重要载体，但出土竹简常因脱水和应力作用而发生严重形变，给复原工作带来巨大挑战。传统人工复原耗时且存在损坏风险，而现有生成模型难以应对竹材中复杂的非线性形变。我们提出一种面向形变竹简逆向复原的新框架，提供渐进式的物理形变建模与逐步逆向位移预测。该方法基于木材纤维微观结构与应力—扩散耦合效应，建立了可计算的形变数学模型，使正向过程能够以确定性的、物理驱动的渐进演化方式模拟物理上合理的形变轨迹。逆向过程则从预测抽象噪声转变为学习具有物理意义的逆向位移场，从而逐步复原形变。实验结果表明，该方法在保持精细文字特征的同时显著提升了复原保真度，能够可靠地校正传统技术难以处理的复杂非线性形变。通过将竹材物理特性的洞见与渐进式复原建模相结合，本工作为数字考古复原建立了一种新范式，有望改变形变文物被重建与研究的方式。代码见 https://github.com/VillanelleQQ/PGDR-BambooSlips。

Bamboo slips are essential media for recording ancient East Asian civilizations, but excavated slips often suffer severe deformation due to dehydration and stress effects, creating substantial challenges for restoration. Traditional manual restoration is time-consuming and risks damage, while existing generative models struggle with the complex non-linear deformations in bamboo materials.We propose a novel framework for inverse restoration of deformed bamboo slips that provides a progressive physical deformation modeling with stepwise inverse displacement prediction. Our approach establishes a computable mathematical model of deformation based on wood fiber microstructure and stress-diffusion coupling effects, enabling the forward process to simulate physically plausible deformation trajectories as a deterministic, physics-driven progressive evolution. The inverse process transforms from predicting abstract noise to learning physically meaningful inverse displacement fields that progressively restore deformations.Experimental results show substantial gains in restoration fidelity while preserving delicate textual features, enabling the reliable correction of complex non-linear deformations that defeat traditional techniques. By integrating physical insights into bamboo material behavior with progressive restoration modeling, this work establishes a new paradigm for digital archaeological restoration--one that holds significant potential to transform how deformed cultural relics are reconstructed and studied.
