"刮削下的碎屑" can be translated as "scrapings" or "shavings" in English, depending on the context.
"Scrapings" typically refers to small pieces or fragments that have been scraped or rubbed off a surface.
"Shavings" usually refers to thin, flat pieces that have been shaved or cut off from a larger piece, often with a tool like a knife or plane.
In the context of scraping or shaving off material, both terms could be appropriate, but "shavings" might be more commonly used when referring to the thin, flat pieces that result from shaving operations, such as in woodworking or metalworking. If the context is more general or the pieces are not necessarily thin and flat, "scrapings" could be a more inclusive term.
