Fusion reactions are different to the ‘fission’ reactions which power nuclear power stations. There, heavy and unstable atoms are split apart to produce energy (and radioactive by-products too). "裂变 "反应与为核电站提供动力,聚变反应与其不同。裂变反应中较重原子的和不稳定原子被分裂开,产生能量...
How does a combustion reaction differ from other chemical reactions? What can change the rate of a reaction? What is a decomposition chemical reaction? How do you do stoichiometry equations? Is fusion a chemical reaction? In a chemical equation, where do the reactants appear?
Safe- The amounts of fuel used for fusion are small compared to fission reactors. This is so that uncontrolled releases of energy do not occur. Most fusion reactors make less radiation than the natural background radiation we live with in our daily lives. Clean- No combustion occurs in nucle...
Even so, fusion energy has long remained an elusive vision for the future, in large part because it's complicated and difficult to artificially duplicate the furnaces that power stars on Earth, without expending more energy than the process generates. Extreme temperatures and pressures are needed t...

Despite this intense strain localization, the material does not crack and the grains in the localization band maintain deformation compatibility with the undeformed grains outside it. This is achieved by the activation of secondary slip modes, primarily prismatic, but also by variation in the ...
energy in the wire can continue to move in the resistance in the light bulb and produce light and heat. energy is every where. some energy you can see and some you cannot see. why you cannot see it because it is not in your physical spectrum of light that your physical eye ca...
Fusion does produce some radioactivity in the materials comprising the reactor. But this isn't expected to be anywhere near as long-lived or intense as theradioactive waste produced by nuclear fission—making it potentially a safer and more palatable choice than conventional nuclear power. ...
However, hydrogen does not naturally exist on Earth in its elemental form. Engineers and scientists must produce pure hydrogen from hydrogen compounds, including fossil fuels or water. In order to extract hydrogen from these compounds, you have to exert energy. The required energy may come in ...
hydrogen in its core, it switches to helium, then carbon, then neon, all the way up the periodic table of elements until it reaches iron. The problem is that iron doesn’t produce energy through the fusion process, so there’s nothing holding back the mass of the star from collapsing ...
