an earthquake can be felt

Recently, some users on the microblogging post, said the well-known human history textbooks Zhang Heng seismograph restoration model is in fact the last century 50's, 1800's seismograph in the end is what already looks like no documented. Science writer Fang is issued yesterday, said Zhang Heng seismograph construction year "is likely to recover those models like modern people,hogan outlet milano, just a decoration." China Earthquake Networks Center researcher Feng Rui yesterday expressed, in 2005 successfully restored seismograph model can actually monitor earthquakes.

DAVID only "59 years old"

November 28, Yan Tao users on the microblogging post, said, "I did not know until yesterday, that the national treasure Zhang Heng seismograph,http://dct.1st.gr.jp, is the 1950s was made out of, Wang Duo (archaeologist) according to ancient descriptions of 196 words, combined with British scientists earthquake theory,http://marionette.mtlab.jp, design and invention of the Zhang Heng seismograph. Because elected to the materials, people thought it was Han stuff, in fact, that the beads do not fall out. "

His remark immediately sparked heated debate online. As of yesterday afternoon,http://www.donggen.net/thread-1133983-1-1.html, the quote was forwarded 15,000 times, nearly 5000 comments.

Many users said they did not know before, in the history textbooks and Technology Museum in the frequent appearance of the seismograph was only a "young as 59 years old," the recovery model. They do not know, because of the principle of error, this recovery model does not work, has been questioned and denied Chinese and foreign scientists. "Han" recorded "in order to verify the matter, together deed if God" seismograph, in fact,http://www.axiabridge.com/sunbbs/sunbbs.cgi, already lost. Some netizens said that the fact that greatly affected the people's confidence,nike tn 2014,http://www.stadtjugendfeuerwehr-neustadt.de/forum/thread.php?threadid=1533705&sid=, and even some of the other ancient Chinese scientific and technological achievements "four great inventions" and questioned.

In Beijing,hogan outlet milano, a junior high school teacher to teach the history of Korea said that the current high school history textbook in use, or Wang Duo restored seismograph model pictures, they generally do not deliberately Explain to students that this is the original or restoration model, "Zhang Heng I even portraits are the descendants of the simulation. " Han says that introducing seismograph, they will speak with students "there are organs, an earthquake can be felt, beads will fall."

Zhang Heng seismograph work?

Online waves is not flat, science writer Fang boomed again in the media. He was issued yesterday on Zhang Heng seismograph questioned whether it works.

"Seismograph already lost, whether it has a role in monitoring the earthquake,http://bbs.suofeiya.com/forum.php?mod=viewthread&tid=12167554&fromuid=160427, has become a mystery." Fang said, according to many experts at home and abroad,abercrombie pas cher, "Han Zhang Heng Chuan" brief description, trying to recover the seismograph, but all of these recovery model no one can really be used to monitor earthquakes, but is "art."

Fang said that in 2005, China Seismological Bureau,woolrich outlet online italia, experts announced that they go through three years of research, the establishment of a new seismograph recovery model, and for the first time realized seismoscope function. "They claimed seismograph new model for three real earthquake in Tangshan, Hebei, Yunnan Luxi,http://www.sgjy169.com/home.php?mod=spacecp&ac=blog&blogid=, more Nanmeng arts occurred have been tested. But this three earthquakes occurred at 1976, 2000 and 2001, seismograph new model in 2005 was completed, how could they be tested for it? "Fang said, after understanding that the original new seismograph restoration model is not true test of earthquake occurrence, but the laboratory simulation of real earthquakes.

Fang said that after the new seismograph restoration model built in China more than five earthquakes occur several times a year,moncler pas cher, in monitoring the seismograph recovery model range, but never heard of the recovery model to monitor even once. 2008 Wenchuan earthquake was felt in Beijing,http://drivermagazineonline.com,Scarpe hogan outlet, have not heard of the restoration model on display at the Beijing detected.

Fang is still on paper, "Han Zhang Heng Chuan" seismograph forecast earthquakes recorded in Longxi questioned the authenticity, saying the historical part of the conflicting suspect that the earthquake was "to illustrate the seismograph magical and fabricated the story."

Fang said that no records to prove that after the Zhang Heng seismograph he played a role in the invention. "We do not have to build out a suspect Zhang Heng seismograph station called instrument, but there is no evidence to prove that there is no convincing reason for seismograph has played a seismoscope function, it is possible to recover those models like modern people, is just a decoration. "Fang said.

The new restoration model for the earthquake response

Was involved in the 2005 edition of the restored seismograph model China Earthquake Networks Center researcher Feng Rui, said yesterday that the new seismograph recovery model is a response to the earthquake, and this has been identified several academicians experts.

"Fang earthquakes in this area do not understand." Feng Rui said they use recorded earthquake occurred in the real seismic wave length, as a basis for control of special vibration table,moncler sito ufficiale, complete the seismograph restoration model test. This is an earthquake,giubbino peuterey uomo, "reproduction" rather than simply "simulation."

Feng Rui said that if you want to monitor the earthquake actually happened, building foundations and other facilities shall then seismograph restoration model on top, but this experiment costly monitoring, location and other issues is not a good solution, "We are moving in this work towards. "

For Fang questioned Longxi earthquake,woolrich outlet roma, Feng Rui said, according to historical speculated that the earthquake occurred in 134 AD. Pingrui Jiang stressed that these historical data are the professional history of seismology experts to examine before. Due to old age, and some historical deviations are inevitable,abercrombie, but when the earthquake occurred Longxi conclusion no problem.
