The silver metal cups react with theoxygen in the air and releasing trace amounts of bio-active silver ions into the water, keeping it free from harmful intruders.
In many organisms including humans,the ability of the lungs to capture theoxygen in the air is dependent on a substance called the alveolar surfactant that is present in the lungs.
Combustion means that flammable textile products are decomposed by the heat of the ignition source, gasified,and mixed with oxygen in the air to cause a violent oxidation reaction.
Rainwater, drinking water, weather, climate, coastlines, much of our food,and even theoxygen in the air we breathe, are all ultimately provided and regulated by the sea.
SOFCs have the highest power generation efficiency among fuel cells. In principle, hydrogen and hydrocarbons, including methane and butane,can be used to generate power by producing an electrochemical reaction with oxygen in the air.
The fuel is not burned,but rather the SOFCs generate electricity from the chemical reaction between oxygen in the air and hydrogen and carbon monoxide extracted from reformed city gas, while the MGTs generate electricity from the post-process.
The fuel is not burned,but rather the SOFCs generate electricity from the chemical reaction between oxygen in the air and hydrogen and carbon monoxide extracted from city gas.
At the interface between the air electrodes and electrolyte, oxygen in the air(O2) reacts with the electrons that have moved over to produce oxygen ions, and these oxygen ions are captured in the electrolyte and move to the fuel electrode side.
強い還元力をもち、空気中の酸素分子を還元する。
TDAE has a high reducing power and reduces oxygen molecules in air.
億年前、地球の空気中の酸素は非常に少なかった。
Billions of years ago there was very little oxygen in Earth's atmosphere.
億年前、地球の空気中の酸素は非常に少なかった。
Around 4 billion years ago there was very little oxygen in the atmosphere.
物が燃えるときに空気中の酸素と窒素が化合してできます。
NOx gases are produced when oxygen and nitrogen in the air combine during combustion.
いわゆるNOx(ノックス)で、物が燃えるときに空気中の酸素と窒素が化合してできる。
They are what is called NOx, a chemical product of oxygen and nitrogen in the air when something burns.
気温や湿度、空気中の酸素、光などは味や香りを損なう原因になります。
Temperature, humidity, oxygen, and light may damage the taste or aroma of tea.
空気中の酸素が薄いので、慣れるまでは平地の60~80%程度の強度で運動してください。
Since the oxygen in the air is thin, exercise at an intensity of about 60-80% of the flat ground until you get used to it.
ここで、冬は寒く、風が強く、湿度の大幅に変化する空気中の酸素を低減します。
And here it gets cold in the winter, the wind blows stronger,reduces the oxygen content in the air, drastically changing humidity.
