The fourth harmonic is the one you get from the string vibrating in quarters, at 4 Hz. This note is an octave higher than the second harmonic, and so is also called C. (The eighth harmonic will also play C, as will the sixteenth, and the thirty-second, and all the powers of two up to infinity.)
综上，OpenClaw在中国的普及不仅让算力变现成为可能，更建立了高价值任务轨迹数据采集体系。低成本环境、广泛用户基础和分布式数据收集，使国产模型在训练迭代上占据领先位置，也为未来AI商业化、投资和产业布局提供清晰方向：在Agent时代，数据才是决定模型竞争力和商业价值的核心资产。
