China's“artificial(人造的)sun”,the Experimental Advanced Superconducting Tokamak(EAST), has set a new world record. It 1 worked for1056 seconds at a high temperature close to 70,000.000℃,which is about five times 2 than the temperature of the real sun.
The high heat 3 in a nuclear fusion reactor(核聚變反應(yīng)堆),which is part of the EAST project. It reproduces the natural reactions(反應(yīng)) 4 happen inside our sun and other 5 . The scientists want to develop the artificial sun to provide near-endless clean energy. The EAST project has cost China more than $950 billion.Total costs will run over $1trillion this year.
Scientists around the world have been trying 6 best for many years to develop nuclear fusion.They say it is the best way to provide clean energy,as the nuclear fusion process needs no fossil fuels(化石燃料) and leaves behind no 7 waste.If scientists can make it 8 ,the world will become greener and cleaner. It also means the lower cost of fuels.
Nuclear fusion technology is still not developed enough 9 a global industry.10 .researcher Dr Gong Xianzu. a nuclear fusion scientist says the EAST project is an important step and that the recent operation lays the foundation(基礎(chǔ))for the running of a fusion reactor.
