天坛内的回音壁,圜丘,三音石的传声特征是什麽?

关于“祈年殿”和“圜丘”是详写,其他的景点,像“黑洞”,“六角亭”,“扇面亭”,“双珏亭”等是略写,作者这样处理,一方面是作者对详写的两个景点印象比较深刻,一方面是要突现出“祈年殿”是史上奇迹般的建筑和“圜丘”有趣的“回音壁.”.让人们对这两个景点有更深的了解.

原句：北京的名胜古迹有故宫、天坛、鸟巢等
改正：1.北京的名胜古迹有故宫、天坛等
2.北京的名胜有故宫、天坛、鸟巢等
原因：鸟巢不是名胜古迹,而是现代文明的建筑.
希望会对你有所帮助.

选动物园啊

将古迹改成风景名胜

由 Q吸=cm(t-to) 求水吸收的热量：
Q吸=cm(t-to) =4.2×10³J/(kg ℃)×200kg×(40℃-10℃)=25200000J；
由 η=Q吸/Q放 得到 Q放=Q吸/η 求需要天然气完全燃烧放出的热量：
Q放=Q吸/η =25200000J/70%=3600000J；
由 V=Q放/q 求需要完全燃烧的天然气体积：
V=Q放/q =36000000J/(40000000J/m³)=0.9m³.

足踏圆丘祭昊天,焚香祈愿祷丰年.
红坛碧瓦演天地,古佛神灵佑万川.
皇诏龙吟成古迹,华章史纪入藏笺.

主要是声音的反射,他距离反射面在17米以内,所以没有明显的回声
反射回来的声音和原来自己的声音叠加后感觉声音被放大了
这和天坛圜丘坛的形状是很有关系的,圆的,所以反射面多

有时间还是去颐和园吧,有山有水有亭台楼阁,景点很多,空气也比较好,还能划船,玩上一整天都可以.
如果时间不够,就选天坛吧,最多1、2个小时就足够了,因为没多少东西,不过毕竟是皇家祭天之地,吸天地之灵气,集日月之精华.

声学原理
回音壁“回音”的原理是圆形墙面连续反射声波,所以说话时要和墙有一定的距离.
回音壁就是皇穹宇的外墙,围墙建造的磨砖对缝,十分的平滑,是很好的声音载体,可以传声,在传递途中对声音损失极小,只要对着墙说话,就算相隔四五十米,见不到面,都可以清晰的听到对方说话.

The Temple of Heaven was constructed between 1406 and 1420 during the reign of Ming Emperor YongLe (1403-1424), who also oversaw the creation of the Forbidden City during the same period.
The Temple of Heaven was originally established as the Temple of Heaven and Earth, but was given its current name during the reign of Ming Emperor JiaJing (1522-1567), who built separate complexes for the earth, sun and moon. The Temple of Earth (DiTan) can be found in north Beijing. The temples of the sun and moon are in the east and west of Beijing.

The Temple of Heaven（天坛）

1.Where is The Temple of Heaven in Beijing?
2.
== 是写文章吗
The Temple of Heaven is located in southern Beijing.It is included in the UNESCO world heritage list in 1998.With an area of 2.7 million square meters,it is the largest of its kind in the country.Built in 1420,the 18th year of the reign of Ming Emperor Yongle,the temple was where emperors went to worship heaven for good harvests.
The temple consists of two parts——the inner altar and outer altar.The main buildings are in the inner altar,on the north-south axis.At the southern end are the Imperial Vault of Heaven(1) and the Circular Mound Altar(2).On the northern end are the Hall of Prayer for Good Harvests(3) and the Hall of Imperial Zenith(4).The structures at both ends are connected by a 360-meter-long walk.There is also the Hall of Abstinence(5) inside the West Heavenly Gate in which the emperor fasted for three days and bathed before prayer.
The temple's main building is the Hall of Prayer for Good Harvests,where the emperor prayed for good harvests.The round hall,38 meters high and 30 meters in diameter,has triple eaves and a cone-shaped deep blue tile roof crowned with a gilded knob.Surrounding the hall is a six-meter-high spacious circular stone terrace on three levels,each edged by a balustrade of carved white marble.

病因：归类不当（“鸟巢”和“水立方”不属于名胜古迹，应该属于现代工程）故，应改为：我去北京参观了故宫、颐和园和天坛等名胜古迹。
