Zhang Heng seismograph for the modern production experts say no one has ever seen the original

Zhang Heng's seismograph is just a legend?

Yesterday, the hottest topic of microblogging what? That Zhang Heng seismograph. User Yan Tao said: "until yesterday that I know, the thp probook 4310s battery of the Zhang Heng seismograph, is the last century, the fifties was made out, and Wang Duo, according to ancient books describe in 196 words, with British scientists earthquake theory, design and invention The Zhang Heng seismograph, as elected to the materials, people all thought it was Han goods, in fact, that the beads do not come out ... ... "In primary school textbooks, we will know the Zhang Heng seismograph. But yesterday, most people know, you can see that the seismograph is a modern system that ignited the controversy.

Zhang Heng's seismograph, experts say there really is

But no one has seen a sawed

Textbook is a modern seismograph in the production of

Original no one has seen a seismograph sawed

"National Museum of the seismograph and Ian are manufactured!" Bo on this topic is in the micro crazy reproduced, and even led to netizens for the existence of Zhang Heng's seismograph questioned. User "Lianwai banana thirty-two" wrote: Zhang Heng's seismograph was made of modern Wang Duo? I know they are from elementary school textbooks, and now has cheated more than a decade! "User" Wo was Gigi, "said:" The ancient Chinese poet, scholar-rich, the lack of objective scientific account, we get over the awkward combinations of adjectives to play. Five thousand years, the number of invention is really lost? Probably the history of the invention is a cottage. "

Press survey found that, according to historical records, Zhang Heng after years of painstaking research, seismograph come in 132 years. 133 on June 18 earthquake in the capital suddenly, Han Zhang Heng Shundi letter, you must change the strategy of the ruling God to bless the world. Han Bao Liu Shun, who favored the crime under the edict forced, Sagong Wang Gong are removed, and Zhang Heng has been promoted to sijung, as his assistant. Seismograph invented by Zhang Heng as a scientific instrument is given a sacred function, as a test artifact of imperial power and fair.

However, seismograph soon lost. AD 190 to 220 years ago, the seismograph did give the people of sight.

Seismograph how did they disappear? "Because it is copper, may be of the lost, there may be buried in the ground, has not been archaeological finds before, had seen the Zhang Heng seismograph in the end a long look like." Expert speculations said.

Recovery seismograph age of only 59 years old

Nanjing Museum's restoration experts said Wang Chao, and now we see Zhang Heng seismograph indeed age of only 59 years old, not 1,800 years old, Wang Duo, produced in 1951. The statue hidden in seismograph National Museum of China, published in the primary and secondary textbooks, printed on stamps, in over half a century, we think that is like Zhang Heng's seismograph.

According to the textbook description, where the earthquake occurred, the corresponding position on the seismograph of Pearl will fall in the toad's mouth. But over half a century, the dragon's mouth is firmly in his mouth, not relent beads. This is caused by Internet users questioned the reasons for Zhang Heng seismograph is not just a legend? 1800 years of ancient deceived everyone?

Wang Chao said that Zhang Heng seismograph handed down without any kind, hp probook 4210s battery is limited. Heritage experts and Wang Duo accordance with the "Later Han - Zhang Heng Chuan" says "looks like Jiuzun" record design its shape and internal structure of the historical data, only a mere 196 words, he is only in accordance with the "hanging pendulum" principle to design the structure. Later, Wang Duo and modify the drawings, according to the Book of "in both columns," the records and refer to the "vertical bar" principle, with a year, in 1951 the proportion of the wood recovered from 1:10 "Zhang Heng seismograph" model. "However, that is a model that was not said to experience the earthquake."

However, this wooden model is that most Chinese people think that is the prototype in many local museums, the model was also used as artifacts to imitation and collections, not only entered the textbooks, even the China Seismological Bureau also used this recovery model logo done for decades, until recent years was removed.

Ancient seismograph Kaopu question it?

From 1875 to now, 100 years in the past, there have been 13 restored seismograph conceptual model, including the works of Wang Duo included, can not experience the earthquake. So, the original Zhang Heng seismograph, in the end it can not experience the earthquake?

"I asked myself in my heart many times, it will not be the ancient people to give their own 'paste', and threw a big lie?" Zhang Heng seismograph in order to accurately understand the scientific principles, since 2002, the China Earthquake Networks Center research fellow Feng Rui and Zhang Heng's seismograph research group carried out a scientific rehabilitation research.

"The answer is yes, certainly Zhang Heng seismograph, and it will work." Through the efforts of up to 8 years, Rui Feng replied in the affirmative.

Feng Rui, said seismograph recovery model can not work because the face several challenges: "Han Zhang Heng Chuan," the 196 was the only historical character, in accordance with the "card not stand alone" principle, should not and can not to do restoration work. Moreover, before the recovery model are not carried out on site visits Han Ling-tai. Second, the 138 years of propaganda is misinformation on the Longxi earthquake, because the same "Han" recorded "to unknowingly move" contradictions. Again, the principle decision to form, the shape of an inevitable failure theory wrong, it needs to be unearthed Han Jiuzun to conform to historical HP Pavilion tx1000 battery, but also different from the "Wang model" shape.

Modern people to really live seismograph

After 8 years of exploration, Feng Rui Zhang Heng seismograph work to find the key. National Library of rare books in his library with the assistance of special collections, to find the earliest record of domestic saving has seismograph old version edition of 7 copies, evidence of China's historical records for the seismograph is not a solitary card. "" Later Han - Zhang Heng Biography "written before the existence of our country have been recorded in the seismograph."

Find more information, visit Feng Rui began Lingtai trip. Historical records, Zhang Heng seismograph invented 132 years later, put it on the south of the capital of Luoyang in the Lingtai 2 observations. Archaeology of the Chinese Academy of Sciences in 1975 on the archaeological excavations carried out Lingtai ground, shooting a lot of photographs. "We investigated that the south bank of the River Luo Lingtai in the floodplain land, belonging to a relatively high background noise environments."

Through these documents, Feng Rui calculated the height of Zhang Heng's seismograph, hanging pendulum length, the oscillation frequency. At the same time, the research group to the transfer of waveform Longxi previous earthquakes. Waveform through the calculation of Zhang Heng's seismograph proved 134 years is indeed measured in the year to Longxi earthquake. Zhang Heng seismograph is really not a "legend" and "myth." "Now, Zhang Heng seismograph can really work."

September 20, 2009, the new Museum of Science and Technology Museum of China opened a new museum and the seismograph in the audience, and the shock wave in a simulation of the seismic work carried out spit balls. Viewers can press the button hands, observed at different wave seismograph under different reaction - just wave it before the arrival of spit balls, the other from the shock wave, seismograph can not make any hp pavilion dv8000 battery. This exclusion of other disturbances such as heavy door, the shock transit vehicles, huge guns and so on.
