《现代汉语词典》“曝光”的“曝”在P母,注明“暴”是它的异体字。在B母有“暴光”,注“曝光”;这就是说“暴光”就是“曝光”。有一本新词新语词典说,“曝光”也称“爆光”。这么一来,pùguāng的pù书面形式有了三种:曝、暴、爆。“曝光”作“暴光”好理解,作“爆光”就觉得有些牵强,至少对它的来源很难说清楚。 “Modern Chinese Dictionary” “exposure” of “exposure” in P mother, indicating that “violence” is its variant character. In B mother has “exposure”, note “exposure”; This means that “exposure” is “exposure.” There is a neologism dictionary that says “exposure” is also called “exposure.” As a result, there are three pùguāng pù written form: exposure, violence, explosion. “Exposure” as “exposure” to understand, as “exposure” to feel a bit far-fetched, at least its source is hard to say clearly.
