Asthma( 哮 喘 ) is a long-lasting breathing disease that affects millions of Americ

ans, many of whom are children. People who get asthma will suffer from lack of breath, difficulty in breathing or coughing---which are caused by the tightening of the muscles in airways. Untreated asthma can lead to poor lung function and death, but asthma can also be effectively controlled with proper treatments. Research is discovering genes that contribute to the development of asthma. This development has pointed researchers to the role of indoor and outdoor pollution as environmental factors that contribute to the increased occurrence of asthma. The Indoor Pollution Indoor pollution has increased with the developments in building materials and in heating and air conditioning systems. In addition to poisonous gases that come from paint, other materials like dust and perfumes used in household products such as washing powder are recycled continuously through the house, winter and summer. Unlike the days before central heating or before whole-house air conditioning, these materials and chemicals cannot get out of modern homes. Most often, they cause breathing problems in the members of the family with the least-developed autoimmune( 自 身 免 疫 的 ) systems. Proper venting ( 通 风 ) and use of environmentally-friendly building materials and carpeting can help reduce the presence of these chemicals. The Out door pollution Researchers have also established outdoor pollution’s role as a probable cause of asthma. Asthma has been proven to result from some fuel products. Smog and the small matters carried by it have been recognized as a factor which leads to asthma

since the 19th century when London saw more and more diseases in the industrial population. Industrial pollutants and other chemicals which are produced in water treatment and open treated water like that found in the swimming pools also contribute to increased cases of asthma as well as other illnesses. Those most affected by the increase of industrial and environmental pollution are children. Although much has been done to control the levels of pollution in the US, there still remains much to do as it is a worldwide phenomenon. Until an international effort can be made to limit carbon emissions, the occurrence of environmental asthma will probably continue to increase.

The proof of that came out today in accounts of the plan to get bin Laden: Once the CIA and the U.S. military focused in on bin Laden’s potential hiding place in the Pakistani town of Abbottabad, views from above could be turned into a detailed map of the building, most likely with the help of the National Geospatial-Intelligence Agency. The map was so detailed that the operation’s planners could build a copy of the building for rehearsals (演习). “The outer features of the building were studied intensively,” John Brennan, the White House’s deputy national security adviser for homeland security and anti-terrorism, told journalists today. The Pentagon (五角大楼) used a group of military satellites for imagery in a variety of wavelengths, but it also picks up pictures from commercial satellite companies such as GeoEye and DigitalGlobe — the same companies that provide mapping data for websites such as Google Earth. A series of satellite pictures can be used to trace the history of the building site from an empty lot in 2001, to a newly built complex in 2005, to an even more built-out neighborhood this January. Tracking down the precise location of bin Laden’s base on satellite imagery occupied the attention of geo-geeks for hours, until the CIA provided the solution to the puzzle. Postings on the Google Earth blog trace every step of the hunt. Once the decision was made to go ahead with the surprise attack, another set of satellites came into play: A space-based military satellite system that provides a secure communication channel between the warfighters in the field and the experts directing the operation from far off.

President Obama could monitor the action in real time from the White House Situation Room, just as CIA Director Leon Panetta could from the spy agency’s headquarters. The main satellites involved here are the Defense Satellite Communications System, or DSCS-III and the Milstar system. Milstar has more capability for secure communications, but it doesn’t offer as much signal bandwidth as DSCS-III. The satellite system links up with communication terminals that are installed at bases on the ground, placed on ships stationed offshore, or even carried around by the helicopter fighters. The Navy SEALs who took on the “get bin Laden” mission typically wear helmet-cameras that can send a stream of coded video halfway around the world. These high-tech surveillance (监视) and communication tools finally provided the U.S. military with a high-tech edge over bin Laden and his supporters, who had to go low-tech to avoid detection. But it was just that very low-techiness that gave away to the CIA: The fact that a million-dollar complex had no phone lines or Internet links led analysts to suspect that they had the right target in their sights.
