北京天坛是世界上最大的祭天建筑群,天坛南端的回音壁、三音石及圜丘台以其奇妙的声学现象闻名中外,成为我国四大回音建筑之首.四十年前中科院院士汤定元先生率先对这几个声学现象进行了科学猜测,受当时条件限制他无法用实验来检验这些科学猜想正确与否.他的这些假设在以后四十多年中广为流传,以致不少人以为它就是真理.我们经过仔细考察发现①它没有经过实践检验,只能为假
Beijing’s Temple of Heaven is the world’s largest building for worship. The Echo Wall, Sanyue Stone, and Luqiu Terrace at the southern end of the Temple of Heaven are known for their wonderful acoustics. They have become the first of four major echo buildings in China. Forty years ago, Academician Tang Dingyuan of the Chinese Academy of Sciences Mr. Chen took the lead in making scientific guesses on these acoustic phenomena. Due to conditions at the time, he could not use experiments to test whether these scientific conjectures were correct. His assumptions were widely circulated in the next 40 years, and many people thought that It is the truth. After careful inspection we found that it has not been tested in practice and can only be false
