Japan’s Jiji Press reported that 20 Chinese naval destroyer Su Shepao aimed at 13 to track the Chinese Navy, Japan Maritime Self Defense Force fleet of P-3C patrol aircraft. Reported that the Chinese navy’s behavior was “threatening behavior”, made the Japanese patrol aircraft in a “state at any time could be shot down” is “the former Soviet Union during the Cold War has not only taken Japan Jian Shi had such action”, the Japanese government is through diplomatic channels to negotiate with China.
Reported that the Japanese time at 15:30 on the on the 13th (14:30 Beijing Time) China’s naval fleet of destroyers Su Shebao targeting “is in accordance with international law for normal patrol flight,” the Japanese P-3C patrol aircraft. Chinese Navy spent a total of 2 Su Shebao targeting Japanese P-3C, and at any time fire status.
Japan’s Jiji Press commented that, even in the former Soviet Union during the Cold War did not have to take such action, the Chinese navy in the Pacific and Japanese coastal waters, on what to do? Japan must be carefully observed.
However, according to common knowledge, modern warships are generally used on the Su Shebao intercept anti-ship missiles at close range on, one can imagine the Japanese and Chinese warships patrol aircraft at a distance of nearly. Japan’s P-3C patrol aircraft is a powerful anti-ship anti-submarine platform, you can drop anti-submarine torpedoes, Harpoon anti-ship missiles and other airborne weapons.
Japan has a huge number of P-3C force, a strong anti-submarine capability. P-3C mission alone both, can also be used to support such as aircraft carriers, amphibious battle group like the friendly. Its mandate expanded to include the other side attacks, anti-submarine and mine-laying, reconnaissance and surveillance. P-3C weapons including the AGM-84 “Harpoon” anti-ship missiles, AGM-65 “Maverick” ground missiles, MK-46 torpedo. P-3C can also plug in the bomb bay and rack up to 9 tons of mine to bring.
Japanese Foreign Minister that the Chinese ships by the Japanese coastal waters beyond reproach
According to Kyodo, the Japanese Foreign Minister Katsuya Okada 21 in the House of Representatives Foreign Affairs Committee, said recently at the Japan-China summit in Washington talks did not involve Chinese ships in Japanese coastal waters in the matter. He said “There is no mention of this matter during the talks the Prime Minister Hatoyama Yukio and officials around the result of comprehensive consideration.”
Reported, Okada explained: “The Chinese ship by the Japanese coastal waters is allowed by law. Even (Japan) territorial sea is also possible, bearing in mind this is not to enter territorial waters.”
Including missile destroyers, submarines, warships, including 10 in China before the implementation of the East China Sea gas field in the vicinity of the ship-based helicopter training and passed the Okinotorishima offshore. Offshore activities may still be present.
Shanghai Oriental Pearl lightning strike fire like matches

Oriental Pearl TV Tower on fire
June 2006, the Oriental Pearl TV Tower over the lightning
At 23 o’clock on the April 12, 2010, the Shanghai Meteorological Observatory issued yellow warning lightning.
April 13, early morning lightning Huangpu River. Two twenty or so witnesses to see the Oriental Pearl TV top Burning like a match.
1 hour and 20 minutes later, fighting and rescue work has basically ended. Pearl of the Orient the responsible person, top of the tower caught fire because of strong lightning in the top of the tower transmitting antenna, antenna housings caused by combustion.
As a landmark in Shanghai, one of the high 467.9
M Pearl of the Orient is not the first time encountered by lightning. Lightning on the high-rise buildings in the “preference” does not impede the quest for the truth: the lightning incident, whether natural disaster or a man-made?
Current Guests: off like a stone, mine experts, the International Electrotechnical Commission IEC/TC81 (Working Group III) of China experts. Born in 1945, in lightning protection of nearly 20 years, has many achievements in the field of lightning protection standards.
“The thunder outside antenna in a fiberglass cast, after the breakdown of the insulating layer of non-fire retardant asbestos.”
“Pearl of the Orient was a flank attack is a normal thing, the higher the building the greater the chance of being swiped.”
“Pearl of the Orient using less semiconductor lightning eliminator with long needle, the product of 90 years in the last century caused a great academic debate.”
Shanghai Oriental Pearl TV Tower, Beijing suspected the fire started by lightning Lightning Detection
Non-fire retardant asbestos induced Oriental Pearl
Tower to the top has been burned black
“Tower struck by lightning not uncommon, but the fire is the first time I heard.” Kwan, 65, as the stone of the last 20 years in lightning protection, lightning in the Pearl of the Orient after the incident, he was as usual to the media reports are collected up.
He said Shanghai is indeed a time when the fire tower is thunder, the day of the radar echoes can be proved. If lightning strikes in the Pearl of the Orient cement wall, cement down the lightning current will go down in a bar, “better, then even if the skin is nothing concrete, the situation of almost likely to play down a cement or brick.” However, according to the relevant analysis, as stone, hit the mine sideswipe outside antenna fiberglass cast, ignited after the breakdown of asbestos insulation.
Shanghai Fire Network news confirmed this is the signal launchers fire wall on the cable and housing on the asbestos Wasi. Stone said, as related on February 9 last year, the CCTV fire also because of the asbestos insulation ignited by fireworks.
According to his analysis, the Oriental Pearl non-asbestos insulation layer of flame retardant materials. He said this event gives us a big lesson is that high-rise buildings within the walls must use fire retardant insulation material, “Pearl of the Orient if the insulation is flame retardant material, will not fire.”
No lightning eliminator
Semiconductor few long needle eliminator
The International Electrotechnical Commission standard, wrote: “So far there is no one kind of equipment and methods to change the weather phenomena of nature to prevent the occurrence of lightning and the lightning in the vicinity of the building or buildings.” In the implementation of relevant norms, three types of lightning protection lightning protection device efficiency buildings were 95%, 90% and 80%.
“Some people believe that lightning protection devices installed after the building was perfectly safe. From an economic point of view, to achieve this is just a waste. Therefore, the special that” or reduce “to show it is not foolproof, because the design in accordance with this standard anti- mine safety device is not 100% mine. “” Building Lightning Protection Design Standards “provision in the Article 1 reads.
Therefore, in the final years of the last century, the once red-hot country, claiming up to 100% elimination of mine (usually occurs from high up the building run leader triggered lightning) and the main discharge current gradually weak 99.9% less semiconductor lightning eliminator with long needle caused controversy in academic circles. Pearl of the Orient is exactly this eliminator.
Since 1995-1998, China’s academic community for this one product, launched a major debate. Lightning experts debate by many as “the development of the mine a major impact on the industry one of the events.” In 1997, organized by the Beijing Municipal Disaster Reduction Association Symposium eliminator after the end of 22 in Beijing from various scientific research, design, and the University engaged in the work of scientists and joint mine wrote an article calling for the authorities strictly and promptly rectify mine standards, norms and product market.
This 22 scientists, including the originator of China’s mine, now 90 years old when Wang Xu, National Standard, “Lightning in design,” the drafters of Lin Weiyong to study the “Tiananmen Square, Great Hall of the lightning protection” horse simulation HTC et al.
Off as the stone is one of the 22 science and technology workers. He took out a 22 year joint editor of a letter addressed Science and Technology Daily, which wrote: “your newspaper published an article entitled” Order of nine days, P Plus Green Lightning protection – less semiconductor lightning eliminator with long needle development and promotion of Revelation . “After reading our long-term construction, electricity and other departments engaged in research and run the comrades, on paper, and a distorted view of the fact that shocked. For a long time, international academic organizations did not recognize the eliminator, the international standardization bodies to resist Such products will be included in the standard. at home, since the consumer since the advent of lightning, because it has no scientific basis is controversial, especially without a scientific experiment to validate its performance kept it a lot of promotion to the market, used in engineering, causing huge losses of state property, people feel sad. To this end, numerous discussions, we have drawn out the views to be published in your newspaper to set the record straight. “
In a debate, the electricity sector, the Ministry of Posts and Telecommunications issued a document to other units to stop using the eliminator. But “45 years ago, Pearl of the Orient looking from another time, for the or the eliminator of new products,” Stone said this off as a lightning event at least prove that the “eliminator does not eliminate the mine.”
High-rise building measures should be done against a flank attack
“Pearl of the Orient was a flank attack is quite normal, not a small probability event,” said Kwan as stone.
The world’s first tower was struck by lightning is known as “Europe’s first tower,” Austin Tan Jinnuo Moscow TV Tower, 573.5 m high. It was in 1972 statistics, it is 4 years and a half years was a 143 times by lightning. Ray often played the middle position in the Moscow television tower, this phenomenon has aroused the concern of mine academia, lightning EGM theory was born.
Lightning EGM decided to high-rise buildings flank attack might occur, the higher the building the greater the chance of being swiped. In the 2000 edition of “Lightning in design”, according to the height of the building on the first class, second class, third class Fanglei separately anti sideswipe building requirements. Pearl of the Orient in the second class of mine buildings, standard construction requirements for this type of “high degree of more than 45m of reinforced concrete structures, steel structures, still should take the following anti-flank attack and other potential protective measures.”
But Kwan learned as stone, and many buildings not designed to do against a flank attack, “some are too ugly.” According to his analysis, this time the site was struck by lightning do not measure against a flank attack. After the incident, the most so that he worried about whether the ball has done a tour level measures against a flank attack. Tourist layer on the sphere diameter 45 meters 263 meters high, is the best place overlooking the Greater Shanghai and another in the revolving restaurant 267 meters, DISCO dance hall, piano bar and is located in 271 meters of the 20 KTV private rooms. The ball was struck by lightning in the area with the same glass-steel housings are, “If there is no anti-flank attack on the trouble.”
