题目内容
When Chinese scientists unearthed more than 1,000 bamboo slips (竹简) in a 2,000-year-old tomb in Hubei Province earlier this year, they were more worried than happy. How could they stop these priceless ancient works from being damaged by the light? As soon as the slips dried out, they would break and the words written on them would be lost forever.
Scientists have had similar problems dealing with some of China's greatest discoveries. The Terracotta Warriors and Horses (兵马俑) of the Qin Dynasty, for example, lost their bright colors when they dried out after coming into contact with the air. Fortunately, Chinese experts are now using modern techniques to preserve cultural relics (保护文物). They have started covering the warriors with a very thin layer of chemical paint to protect them. This paint absorbs sunlight and keeps out bacteria (细菌), so the colors don't fade.
As the bamboo slips found in Hubei were waterlogged (浸水的), another technique is used. Scientists take out the water and replace it with alcohol (酒精) and special chemicals before letting the wood dry. However, not all solutions are modern ones. In some cases, scientists have turned to history for an answer.
