Since the sandwich-like structure of the integral foams resembles that of natural wood, the foams are often referred to as artifical wood or plastic wood, thereby emphasizing not only the formal 978-3-662-02488-1978-3-662-02486-7作者: FEAS 時間: 2025-3-22 01:36 作者: 推延 時間: 2025-3-22 05:45 作者: 適宜 時間: 2025-3-22 12:21
