To the reporter writing, Yan Tao microblogging, reprint more than 13,000 people, nearly 4000 messages.<br> <br>Museums and seismograph books are imitations<br> <br>Jia Yi Qian users message said, the junior high school history books explain very clearly on display in the Museum of Chinese Zhang Heng seismograph, it is a modern imitation. The Zhang Heng seismograph,piumini moncler, can not predict earthquakes,hogan outlet online, but can distinguish the general direction of the earthquake. In his view, Yan Tao to ignorance as personality.<br> <br>In other words, the emergence of the history books seismograph, also according to historical records recovery. The seismograph is used to report the disaster, not predict earthquakes.<br> <br>About seismograph records, best known as "Han Zhang Heng Chuan." The book records on the seismograph, a total of 233 words, and the appearance of narrative,H6N05DoCao, only 196 words. "In refined copper cast, who diameter of eight feet,moncler outlet italia, closing lid uplift, the shape of the wine respect, there are columns." "Outside the eight dragon, the first title copper pill,tlqV6n75Ox,air max 90 pas cher, under the toad, bearing the mouth."<br> <br>The book records, in 138 AD, February day, Zhang Heng's seismograph is on the west to the mouth of the dragon suddenly opened, he spits out the copper ball. According to Zhang Heng design, just to the west of the earthquake, but no trace of the capital Luoyang little earthquake.

Eastern Han Dynasty to the Western Jin Dynasty, continuous war, AD 190, a fire destroyed the Dong Luoyang, Zhang Heng seismograph therefore lost, since 1800 years.<br> <br>Currently seismograph, are descendants of the restoration model.<br> <br>1951, Wang Duo, according to historical data, completed the restoration work on the seismograph. 1952 was immediately incorporated into the national school textbooks, which is a lot of people mistakenly think it is an important reason for archaeological finds. & Nbsp;<br> <br>Although Wang Duo design model is extremely popular, and a large number of popular science books in the introduction, but historians, archaeologists and seismologists serious academic papers, but not a positive reference it. "Professionals just take it as a conceptual art form, never in the strict scientific sense them as seismic instruments had to accept and affirm." Said an academic.<br> <br>Film and television work, seismograph, Sinan and other images often appear, so in addition to outside historians, have had a seismograph is unearthed relics of illusion.<br> <br>Ian implicated guide action being questioned<br> <br>Sign king of the hill, said Sinan and Zhang Heng seismograph, just as Wang Duo to do, but never succeeded, "charging it,KCjVF9HJ9R, will be able to guide the charge." According to the prevailing view in academia, Han Wang Yun "On balance it is to be articles "mentioned in the" Ian "is a magnetic guide apparatus. The paper records, "scoop Sinan, the throw to the ground, their final analysis guide." "Scoop" is the spoon. "Land" refers to the site holding the spoon. "In the final analysis" is the spoon handle. That is to say, made spoon-style "Ian", placed in a hard glossy "site" on its handle will automatically point to the south.<br> <br>1950s, Wang Duo, according to this record, referring to the Han spoon looks like, we are familiar with today restoration of Sinan.<br> <br>However, Sinan produced no easy task.<br> <br>"Science squirrel will" article "Ian fog" analysts said one magnet ground into a spoon-shaped,gK96dF07JE, very difficult,pBFhs9L3yu, the yield is very low, so find an experienced Physics jade work to do; the second is in the process of trying to figure magnet, magnetic the effect of weakening the guidelines is poor; the third is a large contact surface of the bottom of it and the site of friction also increased accordingly, rotation is not flexible,doudoune moncler soldes, the impact of the guidelines results. After the two is probably the reason that Ian does not guide lies.<br> <br>Users questioned seismograph and Ian true<br> <br>Some netizens said, according to historical records, as well as the academic point of view, is the seismograph invented by Zhang Heng, but no one has seen Zhang Heng's seismograph, but can not determine the function and the actual results of the seismograph. The figure presented is in accordance with historical records descendants hard to do it.<br> <br>Seismograph and Ian are based on classical historian described the recovery of the mold. Its scientific principles has not yet been recognized by the academic community, in its appearance, function and the actual effect remains to be verified under the circumstances, editing materials is appropriate, become the focus of netizens discussion.<br> <br>Ancient description of the seismograph, Sinan Cherishing such as gold,PD6OGo1x4p, according to a brief description of descendants,, its recovery, and shall look after restoration, is the seismograph, Sinan's true colors, and whether appropriate?<br> <br>Sign Wang Hill said, "and now doubt the story of Zheng He's voyages."<br> <br>& Nbsp; & nbsp; & nbsp; experts said Zhang Heng seismograph modern production Archaeology Department did not find the original<br><br>
