Seismograph model is presented in textbooks
Yesterday, the hottest topic of microblogging What is it? That Zhang Heng seismograph. Sign Yan Tao said: "until yesterday that I know, that the national treasure Zhang Heng seismograph,chaussures nike tn pas cher, is the last century fifties made out, Wang Duo, according to 196 words ancient depiction, combining British scientists earthquake theory, design and invention of The Zhang Heng seismograph,http://xmruidi.com/news/html/?103466.html, as elected to the materials,http://hisamatsu-online.org, people thought it was Han stuff, in fact, that the beads fall out ...... "in elementary school textbooks, we familiar with the Zhang Heng seismograph. But yesterday, most people know, we can see that the seismograph is a modern system that ignited controversy.
Experts say Zhang Heng seismograph really
But no one has seen long-sawed
Textbooks seismograph is a modern production
Original seismograph Nobody seen long-sawed
"Seismograph and Ian national museum is being manufactured!" Topic on the microblogging is crazy reproduced, and even led to netizens Zhang Heng seismograph existence questioned. User "Lianwai banana thirty-two" said: Zhang Heng seismograph is a modern Wang Duo made? I know them from primary school textbooks, and now has cheated more than ten years! "Netizens" He was Gigi "said:" China is rich in ancient literati poet, described the lack of objective and scientific, we compared the effort to get to play the permutations and combinations of adjectives. Five thousand years, the number of lost invention is true? Chances are that a cottage history of invention. "
Reporters found that, according to historical records, Zhang Heng after years of painstaking research, seismograph come in 132 years. 133 On June 18 the capital sudden earthquake, Zhang Heng letter Han emperor, the ruling must change strategy, to bless God in the world. Han emperor Liu Bao was forced to lower crime edict, Sagong Wang Gong are removed,jordan homme, and Zhang Heng has been promoted to attract, to become his assistant. Seismograph Zhang Heng as a scientific instrument is given a sacred function, became the test artifacts imperial justice.
However, the seismograph soon lost. After AD 190 to 220 years ago, the seismograph begins disappeared from sight.
How seismograph disappear? "Because it is copper, may be of the lost, may also be buried in the ground, has not been found through archeology, had seen the Zhang Heng seismograph in the end a long look like." Experts say speculation.
Recovery seismograph age of only 59 years old
Nanjing Museum's restoration experts Wang Chao said, and now we see the Zhang Heng seismograph indeed the age of only 59 years old, rather than 1800 years old, Wang Duo, made in 1951. This statue seismograph hidden in the National Museum of China, published in primary and secondary school textbooks, printed on stamps, in over half a century, we think that Zhang Heng seismograph is like this.
According to reports, textbooks, where an earthquake, and the corresponding orientation Pearl will fall in the toad's mouth on the seismograph. But half a century, the dragon's mouth was firmly in his mouth not promoted beads. This is also the reason causing users questioned,http://seweb.siogon.com/1004/news/html/?412075.html, Zhang Heng seismograph is not just a legend? The ancients fooled everybody 1800 years?
Wang Chao said Zhang Heng seismograph without any kind handed down, the information is limited. Wang Duo, according to heritage experts "Han Zhang Heng Chuan" and said "the shape Jiuzun" record design its shape, and the internal structure of historical data,http://jsem.jp, only a mere 196 words, he is only in accordance with the "hanging pendulum" principle in the design of the structure. Later,http://www.kct.or.jp, Wang Duo and modify the drawings, according to Han in "in both columns," the records and refer to the "upright pole" principle, with the year, the recovery of the wood 1:10 "Zhang Heng seismograph" model in 1951. "However, it is a model, did not say can seismoscope."
However, this wooden model by most Chinese people mistakenly thought it was a prototype, in many local museum, the model can also be used as relics to imitation and collections, not only entered the textbooks, and even China Seismological Bureau also use this recovery model done for decades flag, only recently removed.
Questioned the ancient seismograph fly it?
From 1875 to the present, the past 100 years,chaussure nike pas cher, there have been 13 kinds of conceptual seismograph restoration model, including the works of Wang Duo included, are not seismoscope. Well, the original Zhang Heng seismograph,http://www-ya.magma.ne.jp/~y-jc/cgi-bin/yjcbbs/honey.cgi?mode=howto, in the end can not seismoscope it?
"I asked myself many times in my heart, it will not be the ancient people to give themselves 'paste',http://club.chedian168.com/forum.php?mod=viewthread&tid=193443, and threw the big lie?" In order to accurately understand the scientific principles Zhang Heng seismograph, since 2002, the China Earthquake Networks Center researcher Feng Its sharp recovery group carried out scientific research Zhang Heng seismograph.
"The answer is yes, Zhang Heng seismograph certainly, but also will work." By up to eight years of efforts, Feng Rui affirmative answer.
Feng Rui said, seismograph recovery model can not work because faced with several challenges: "Han Zhang Heng Chuan" of 196 words was the only historical data, in accordance with the "solitary card can not stand" principle, should not and can not do Restoration work. Moreover, the previous recovery model are not on the Han Lingtai conducted site visits. Secondly, over the years its 138 years of Longxi earthquakes are misinformation, because with "Han" recorded "to unknowingly move" contradictions. Again, the principle decision shape, the shape of the principle of error inevitable mistakes,nike tn pas cher france, it needs to be Jiuzun Han Dynasty unearthed in order to meet the historical data, but also different from the "Wang model" shape.
People today strive seismograph really lived
Through 8 years of exploration, Feng Rui found the key to Zhang Heng seismograph work. He was assisted by the National Library of Rare Books and Special Collections library, found the country's first in mind the preservation of the seven ancient seismograph edition version, corroborated the Chinese seismograph for historical records are not solitary card. "" Han Zhang Heng Chuan "written before,http://longbai.info/longbai_info/bbs/forum.php?mod=viewthread&tid=12161843, our country has been in existence for the seismograph record."
Finds more data, the Feng Rui began Lingtai study trip. Historical records, 132 years after the invention of the seismograph Zhang Heng, put it in the capital in the south of Luoyang Lingtai 2 observations. Institute of Archaeology in 1975 Lingtai foundation of archaeological excavations carried out, shooting a lot of photos. "We looked believe Luo Lingtai in the south bank of the river floodplain, are relatively high background noise environments." & Nbsp;
Through these documents, Feng Rui Zhang Heng seismograph calculated height, hanging pendulum length, vibration frequency. At the same time,scarpe louboutin outlet, the group transferred to the previous waveform Longxi earthquake. Through the calculation waveform prove Zhang Heng's seismograph in 134 AD did the Longxi earthquake measured. Zhang Heng seismograph is really not a "legend" and "myth." "Now, Zhang Heng seismograph can really work."
September 20, 2009, the opening of China Science and Technology Museum, the seismograph in the new museum meet with the audience, and spit balls work in a simulation of the seismic shock waves. Viewers can hands-on button is pressed, the effects of different responses in different wave type lower seismograph - it was only the arrival of transverse spit balls, the other from the longitudinal wave of shock, it can not make any response seismograph. This rules out other disturbances such as heavy closed car transit vibration, huge guns and the like. Express reporter Hu Yumei
