【正文】 ning body, has also ordered an immediate investigation into the referee39。s actions.CSKA said they were surprised and disappointed by Toure39。s plaint. In a statement the Russian side added: We found no racist insults from fans of CSKA.Baumgartner the disappointing news: Mission aborted.The supersonic descent could happen as early as Sunda.The weather plays an important role in this mission. Starting at the ground, conditions have to be very calm winds less than 2 mph, with no precipitation or humidity and limited cloud cover. The balloon, with capsule attached, will move through the lower level of the atmosphere (the troposphere) where our daytoday weather lives. It will climb higher than the tip of Mount Everest ( miles/ kilometers), drifting even higher than the cruising altitude of mercial airliners ( miles/ kilometers) and into the stratosphere. As he crosses the boundary layer (called the tropopause),e can expect a lot of turbulence.The balloon will slowly drift to the edge of space at 120,000 feet ( Then, I would assume, he will slowly step out onto something resembling an Olympic diving platform.Below, the Earth bees the concrete bottom of a swimming pool that he wants to land on, but not too hard. Still, he39。ll be traveling fast, so despite the distance, it will not be like diving into the deep end of a pool. It will be like he is diving into the shallow end.Skydiver preps for the big jumpWhen he jumps, he is expected to reach the speed of sound 690 mph (1,110 kph) in less than 40 seconds. Like hitting the top of the water, he will begin to slow as he approaches the more dense air closer to Earth. But this will not be enough to stop him pletely.If he goes too fast or spins out of control, he has a stabilization parachute that can be deployed to slow him down. His team hopes it39。s not needed. Instead, he plans to deploy his 270squarefoot (25squaremeter) main chute at an altitude of around 5,000 feet (1,524 meters).In order to deploy this chute successfully, he will have to slow to 172 mph (277 kph). He will have a reserve parachute that will open automatically if he loses consciousness at mach speeds.Even if everything goes as planned, it won39。t. Baumgartner still will free fall at a speed that would cause you and me to pass out, and no parachute is guaranteed to work higher than 25,000 feet (7,620 meters).cause there 序號名稱規(guī)格型號單位數(shù)量備注一制冷系統(tǒng)1壓縮機(jī)組4AV10臺42冷凝器LN70臺13貯氨器臺14桶泵組合臺15氨液分離器AF65臺16集油器JY219臺17空氣分離器KF32臺18緊急泄氨器JX108臺19冷風(fēng)機(jī)KLL250臺810冷風(fēng)機(jī)KLD150臺411冷風(fēng)機(jī)KLD100臺212閥門套8613電磁閥套614管道及支架噸15管道及設(shè)備保溫m32216管道保溫包扎鍍鋅板噸17附件套1二氣調(diào)系統(tǒng)1中空纖維制氮機(jī)CA30B臺12二氧化碳洗滌器GA15臺13氣動電磁閥D100臺144電腦控制系統(tǒng)CNJK406臺15信號轉(zhuǎn)換器8線臺16果心溫度探頭臺77庫氣平衡袋5 m3個78庫氣安全閥液封式個79小活塞空壓機(jī)臺110PVC管套111附件套1三水冷系統(tǒng)1冷卻塔DBNL3100臺22水泵SBL80160I臺23水泵SBL50160I臺24閥門套305管道及支架噸6附件套1四電儀控系統(tǒng)1電器控制柜套12照明系統(tǒng)套13電線電纜套14橋架管線套15附件套150
