atoms

n. 原子

Two atoms of hydrogen combine with one atom of oxygen to form a molecule of water.
两个氢原子和一个氧原子结合而成一个水分子。
All matter ultimately consistsof atoms.
一切物质从根本上说都是由原子组成的.

Fusion, combining two atoms, is the power of nuclear warheads. Fission, splitting an atom, is the power of old atomic weapons and of today's nuclear power plants.
Other experiments aboard LDEF were designed to gather interstellar gas atoms and micrometeoroid material.
The boron and control rods absorb neutrons from decaying uranium atoms, preventing them from striking other uranium atoms and starting a chain reaction.
The boron and control rods absorb neutrons from decaying uranium atoms, preventing them from striking other uranium atoms and starting a chain reaction.
Alan D. Frankel said he and his collegues have discovered that molecules of an HIV protein called Tat are bound together by metal atoms.
"I understand they want to break down atoms and see what's inside them," said Mrs. Wilburn's grandson, Dale Wilburn, a 38-year-old machinist who lives with her. "I don't really understand much more.
When an electric current is applied to the apparatus, it begins to decompose the heavy water into oxygen and deuterium atoms, just as a high school electrolysis experiment decomposes ordinary water.
Superoxide is known as a free radical, a class of atoms and molecules that are missing an electron and thus are unstable.
The tip holds a magnet-like attraction for atoms.
Richardson and his colleagues, using a $1.5 million super-refrigeration unit, will try to achieve absolute zero _ the temperature at which even atoms stop rubbing together and creating heat.
On other questions, the survey found that 43 percent said correctly that electrons, which are components of atoms, are smaller than atoms; 20 percent thought they were larger and 37 percent had no idea.

The same kind of vision lets us turn atoms into electricity, lets us fling rockets into space and bring them home again.
Cold fusion is the claim that the decomposition of water at room temperature into hydrogen and oxygen by an electric current passing through a palladium electrode leads to the absorption of hydrogen atoms in the electrode.
It differs from nuclear fission, which powers conventional nuclear plants by splitting heavy atoms into smaller pieces.
Scientists in the past had been unable to fuse atoms except at temperatures in the millions of degrees.
Copper-based superconductors work best when the electrical current runs parallel to their stacked layers of copper and oxygen atoms.
The controversy rages over claims that the fusion of deuterium atoms inside the palladium rod releases excess energy.
These contain atoms that function like teeth, biting into and holding certain metals inside the ligand but not others.
The compounds can last 100 years, but when they reach the stratosphere, about 15-25 miles above the earth's surface, they break apart and their chlorine atoms destroy ozone.
The resulting compression causes atoms from the cluster and the target to fuse, producing a small burst of nuclear energy.
The result often is chemical chaos, as each atom or molecule robbed of an electron becomes a free radical itself and instantly seeks electrons from still other atoms and molecules.
I'm very grateful to all my colleagues and co-workers, teachers and family." Ramsey developed a way to study the structure of atoms by exciting them to different energy levels using two oscillating electromagnetic fields.
Fusion, the process behind the sun and the hydrogen bomb, releases energy by fusing atoms together.
Scientists say their chlorine atoms destroy ozone, allowing more of the sun's ultraviolet rays to reach Earth, causing more skin cancer and eye cataracts, and suppressing human immune systems.
Studying the tiny yeast-generated crystals should help researchers understand how small transistors can be shrunk before they begin to take on the quantum properties of atoms and molecules, losing their normal semiconducting properties.
"This is a major new tool that will enable us to actually visualize molecules and atoms, something that has not been possible before," he said in a telephone interview.
Scientists build quantum lasers by "spray-painting" atoms in a layer cake of incredibly thin layers, some of which have impurities added.
The components on these chips are so small - no more than 10 atoms across or 100,000 times thinner than a human hair - that the electrons in them behave both as particles and waves, in accordance with the somewhat bizarre predictions of quantum theory.
Thus, four decades after the nation began splitting atoms to make electricity for consumers and nuclear weapons for the military, prospects for permanently isolating the long-lived reactor wastes from the human environment remain in doubt.
