用磁秤模拟方法研究了冷却速度和过冷温度对镍铬钢排氢速度和排氢量的影响。
The effect of cooling rate and undercooling temperature on the rate and amount of dehydrogenation was studied by magnetic balance simulation method.
在该机制之下，单一减排数量最大的是某些工业气体，如制冷剂的副产品氢氟碳化物。
The greatest single reducer of emissions under the CDM, is the elimination of certain industrial gases – such as hydrofluorocarbons, a by-product of refrigerants.
这部未来风格的跑车是一部氢动力零排放燃料电池超级汽车。
The futuristic sports car is a hydrogen-powered, zero emission, fuel-celled supercar.
这款零排放汽车由氢-电混合动力驱动，燃料电池位于后部。
It is powered by a hydrogen-electric, emission-free, fuel cellsystem located at the rear.
“未来发电”计划将实现建设接近零排放的电厂，在这里将煤转化为氢，再转换到涡轮发电并且产生二氧化碳，将二氧化碳封存在地下。
FutureGen would be a near zero-emissions plant that converted coal into hydrogen, to power electric turbines, and carbon dioxide, to be pumped underground.
这意味着汽车不直接产生二氧化碳排放，但是否完全零排放取决于用来制造氢的能量原料。
This means the car produces no CO2 emissions directly, but whether it is emission-free overall depends on the source of the energy used to produce the hydrogen.
就像Hazen博士指出的那样，碳是宇宙中含量排第四的元素，仅落后于氢，氮和氧。
As Dr Hazen pointed out, carbon is the fourth-most-abundant element in the universe, after hydrogen, helium and oxygen.
国内现有的一些排肥器，在排施易吸湿、潮解的粉状碳酸氢铵化肥时，多数容易引起架空、粘附、堵塞等现象。
When feeding the moisture-absorbing and moistened ammonium bicarbonate, the most of available fertilizer feeders are liable to make the fertilizer bridging, adhering and blocking up.
一辆尚处于实验阶段的清洁能源汽车依靠天然气行驶。另一辆使用从谷物蒸馏而来的酒精。第三辆则装有由氢燃料电池提供能量的零排放发动机。
One experimental clean-energy car runs on natural gas. Another USES ethanol distilled from corn. A third has a zero-emissions electric motor powered by a hydrogen fuel cell.
燃料电池汽车正是利用清洁的氢能源、并可实现零排放的汽车。
Fuel Cell vehicle (FCV) is the vehicle that we are looking for to use clean fuel (hydrogen energy) and realize zero emission.
