【正文】 Baumgartner the disappointing news: Mission aborted. r 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 supersonic descent could happen as early as Sunda.The weatheThe 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.

Due to the development of the digital integrated circuit technology and adopts the advanced quartz technology, walking make digital clock has advantages of accurate, stable performance, easy to carry, it is also used in timing, automatic feed and automatic control and other fields. Although already on the market at present the readymade digital clock chip for sale, cheap, use is convenient, but in view of the single chip microputer timer function also can plete the design of the digital clock circuit, therefore is necessary for the design of digital clock. Here we will have learned more fragmented knowledge of digital circuit of the organic link, the system used in practice, to develop our prehensive analysis and circuit design, programming, debugging circuit ability.SCM has small volume and powerful function, high reliability, low price and a series of advantages, not only has bee widely used in the field of industrial measurement and control in
