“carbon”造句，怎麼用carbon造句

Green plants capture carbon dioxide through photosynthesis and store carbon in their tissues.

Captured carbon would still need to be disposed of.

The fragmentation mechanism of the carbon black was analysed.

Steel is an alloy of iron and carbon. Coking coal is a source of carbon in the smelting process.

"Life seems to exploit every possible chemical pathway to obtain energy and make carbon-carbon bonds," says Hazen.

When carbon unites with oxygen, it forms a colorless, odorless, and tasteless gas called carbon dioxide, which is heavier than air and will extinguish a flame.

Like carbon dioxide, black carbon absorbs sunlight and infrared radiation, trapping heat in the atmosphere — including the boundary layer closest to Earth's surface.

But calculating the carbon footprint of a product is far from easy.

And then we have gas cooled reactors which can use supercritical carbon dioxide or helium.

The resulting carbon dioxide cloud rushed downhill, asphyxiating 1, 700 people and thousands more animals.

For example, planting fast growing pine trees on grassland will help to lock up carbon in the tree, but it may also disrupt the soil and release carbon already stored in the grassland.

Dr Jiao estimates that the amount of carbon stored by the oceans in this way is equal to the amount in the atmosphere, in the form of carbon dioxide.

Though silver is a good conductor, carbon is cheaper, and the nanotubes provide the extra electrical conductivity needed.

The researchers next want to look into what happens when engineers inject liquid carbon dioxide from power plants deep underground, in an attempt to keep the carbon from entering the atmosphere.

The team predicts that further increases in carbon dioxide will halve the amount of water lost to the atmosphere.

They are working in his fields, helping convert another small patch of peatland, and adding to Indonesia’s alarming emissions of carbon dioxide.

Today the copious carbon dioxide emitted to the atmosphere is left for nature to pick up, which it cannot do fast enough.

A car with a natural gas-powered internal-combustion engine emits87 per cent less nitrogen oxide,70 per cent less carbon monoxide and25 less carbon dioxide than a car with an engine that uses petrol, according to research by the Honda Motor Co.

Scientists are tantalized by plants and trees because they store far more energy than is consumed by cars, trucks, trains and planes, and they do it by taking carbon out of the atmosphere.

"Personal carbon offsets are akin to indulgences sold by the Church in the Middle Ages," said Roger Pielke Jr, an expert on science policy from the University of Colorado in Boulder.

Carbon dioxide consists of carbon and oxygen.

The body is fiberglass and carbon fiber.

This releases a mixture of hydrogen and carbon monoxide, known as syngas, and leaves a residue of amorphous elemental carbon called carbon black.

It all depends on how you wield the carbon calculator.

Swedish researchers have shown that carbon retention by sediment is highly temperature-sensitive and that a warmer climate would result in increased carbon dioxide emissions to the atmosphere.

For example, the behaviour of carbon nanotubes — markedly different from that of graphite, another form of carbon — is hard to predict.

At best it can only sequester 90 percent of the carbon emitted.

By removing whales, sharks and large fish, we ve reduced the amount of carbon stored in these populations.

Even if we, say, halve all carbon emissions today, it would not have an immediate effect on atmospheric CO2 concentrations.

Randall designed a series of "carbon conversations" in which she encourages people to explore their attitude to consumption, identity and status.

Although biomass fuel has the potential to be virtually carbon neutral, the demand for cooking wood is driving deforestation in some parts of the world.

Monolithic/refractories are shaped within the furnace with a chemical binding. The commonly-used firebricksare silica brick, semisilica brick, fireclay brick, high-alumina brick, chrome brick, magnesia brick, carbon brick, etc.

Fit the carbon canister holder.

He decided to use carbon because it does not melt.

That's a film formed by applying heat to carbon black mixed with resins. How do you make resins and what, pray, is carbon black?

Currently half the carbon we release into the atmosphere gets absorbed by land and sea-much of it by plants, which take in carbon dioxide in the process of photosynthesis.

Anyone taking all these flights over a year might rack up a carbon footprint totalling more than 35 tonnes.

In the meantime, other scientists had identified a receptor in a group of neurons that enable fruit flies to smell carbon dioxide, which signals the presence of a good meal of tasty yeast.

Besides water, the plume also contained carbon monoxide, carbon dioxide, ammonia, sodium, mercury and silver.

But carbon capture must also be applied to gas power plants.

For another, the atmosphere is filled with carbon monoxide and other deadly gases and nobody could possibly breather this air and survive.

She put the carbon paper in the wrong way round.

That would involve putting a floor under the price of fossil fuels by imposing a price on carbon emissions and import duties on oil to keep the domestic price above, say, $70 per barrel.

But, he said, people must be able to earn carbon credits that can be sold on a global market for preserving soil, which contains 75% of all carbon on land.
