When Matthew Kahn and Iestimated household carbon emissions across American metropolitan areas we found that the three areas with the lowest emissions were San Diego San Francisco and San Jose. Carbon emissions in these places are still more than four times the emissions in the brownest Chinese city and10 times as high as the household emissions in the average Chinese city. Thatgulf reminds us why America has so little moral authority on global warming and why the world's carbon emissions will probablysoar as China and India acquire the living patterns of prosperous nations.

Matthew Kahn和我估算着美国大都市的居民碳排放，我们发现圣地亚哥、旧金山和圣何塞是碳排放最低的3个地区，但是这些地方的碳排放仍然高出中国污染最严重的城市4倍多，而且比中国一般城市的居民排放率高出10倍，这种差距提醒我们为什么美国在全球变暖事务上没有足够的权威性，以及为什么全球的碳排放将继续增长，随着中国和印度正在向富裕国家的生活模式靠近

It imply various complicated composition in the fuel, at burnable after produce various harmful material, even not the fuel with miscellaneous quality attains the complete combustion, also wanting to produce the water and carbon dioxides, positive because the fuel combustion makes the carbon dioxide in the atmosphere density increased continuously, breaking the balance of the nature carbon dioxide, to go to and may cause" green house effect", cause the Earth air temperature rise.

燃料中含有各种复杂的成分，在燃烧后产生各种有害物质，即使不含杂质的燃料达到完全燃烧，也要产生水和二氧化碳，正因为燃料燃烧使大气中的二氧化碳浓度不断增加，破坏了自然界二氧化碳的平衡，以至可能引发&温室效应&，致使地球气温上升。

It is called carbon capture and storage, or carbon sequestration, and entails hoovering up carbon dioxide from the smokestacks of power plants and other big industrial facilities and storing it safely underground, where it will have no effect on the atmosphere.

那就是二氧化碳回收和储存，也叫做碳吸收。这包括将电厂及其他工业机构从烟囱中排出的二氧化碳进行回收，然后将其安全地储藏于底下。这样就不会对大气造成任何影响了。

The impure carbon dioxide which can be obtained from any available source of carbon dioxide will typically contain as impurities sulfur compounds such as carbonyl sulfide, hydrogen sulfide, dimethyl sulfide, sulfur dioxide and mercaptans, hydrocarbon impurities such as aldehydes, alcohols, aromatics, propane, ethylene, and other impurities such as water, and carbon monoxide.

可由任何二氧化碳源得到的低纯度二氧化碳通常含有以下杂质：硫化合物，例如硫化羰、硫化氢、二甲硫、二氧化硫和硫醇；烃杂质，例如醛、醇、芳族化合物、丙烷、乙烯；以及其它杂质，例如水和一氧化碳。

The results show that the normal total emissivity of T700 carbon fiber and T300 surface desizing carbon fiber are lower than T300 original sample, and the variation of spectral emissivity is in three wavebands, spectral emissivity is in three wavebands, this is related with the microstructure of carbon fiber.

结果表明：T700碳纤维和经过表面除胶后的T300碳纤维样品，其法向总发射率有所降低，光谱发射率基本在三个波段范围内变化，这与碳纤维的微结构有关。

During the period of carbon fibers growth, each nano copper catalyst particle can synthesize three pieces of carbon fibers simultaneously, and then Y-shaped carbon fibers were obtained finally.
