Products made of the waste cause the micronuclei rate to be increased because of its low radio active action,but the change in abnormal nuclei rate can’t reach a remarkable level.It shows that rare-earth waste has a certain effect of causing mutation on aquatic organism.Harmfulness of products made from this waste is decreased largely,and resources can be effectively saved.展开更多

The 1,000-year Dai documents, including Buddhist Scriptures on Pattra and the famous Dai calendar, prove that the Dai nationality has long cultural history. The Dai narrative poem, Zhaoshutun and Nanmunuona (a legend about a prince and a peacock princess) and the medical classic entitled Traditional Dai Medicine, are important to the precious Chinese cultural heritage. The Dais celebrate the Water-sprinkling Festival every April.The Dais tend to settle along rivers. The ever-green Dai area has a subtropical climate with thick forests. The plentiful rainfall and the fertile soil are favorable to farming.Xishuangbanna Prefecture, dubbed as the "Kingdom of plants" and "Kingdom of animals", has a variety展开更多
