摘要：
从过去的扰动中存储和检索机械印记是软物质物理学的核心主题。本文研究普通胶带部分剥离时的这种效应，剥离停止点会留下一条强粘接线。我们展示了如何利用这种行为机械存储和检索连续剥离循环的振幅。这种多记忆行为类似于许多滞后系统中常见的返回点记忆，但关键区别在于此处的驱动是整流的：剥离是单向的，每个循环开始和结束时胶带都平贴在基底上。该条件意味着胶带展现出一种独特的多记忆原理。通过考虑最近提出的另一种机制，我们确立“锁存”为整流驱动下形成记忆的通用原理，且存在多种物理实现。我们还分别展示了可调整胶带以部分擦除记忆，并证明胶带可作为机械计算设备，从输入序列中提取特征并比较连续值。
英文摘要：
The storage and retrieval of mechanical imprints from past perturbations is a central theme in soft matter physics. Here we study this effect in the partial peeling of an ordinary adhesive tape, which leaves a line of strong adhesion at the stopping point. We show how this behavior can be used to mechanically store and retrieve the amplitudes of successive peeling cycles. This multiple-memory behavior resembles the well-known return-point memory found in many systems with hysteresis, but crucially the driving here is rectified: peeling is unidirectional, where each cycle begins and ends with the tape flat on the substrate. This condition means that the tape demonstrates a distinct principle for multiple memories. By considering another mechanism that was recently proposed, we establish ``latching'' as a generic principle for memories formed under rectified driving, with multiple physical realizations. We show separately that tape can be tuned to erase memories partially and also demonstrate the function of tape as a mechanical computing device that extracts features from input sequences and compares successive values.
