由于被大致认为作为加速源的暗能量的提出,我们膨胀的宇宙的动力学可以与它适度的物质含量相一致。
Thanks to dark energy-as the source of the acceleration is loosely labeled-the dynamics of our expanding universe can be reconciled with its modest mass content.
他说:“它的废气排放量是零,不排放碳,而且氢是宇宙中含量最丰富的物质。”
It is zero emissions, there is no carbon, he said. And hydrogen is the most plentiful element in the universe.
氢气在宇宙中的含量很丰富,却不容易储存和分离。
Although hydrogen is the most abundant element in the universe, it is difficult to store and distribute.
他说:“它的废气排放量是零,不排放碳,而且氢是宇宙中含量最丰富的物质。”
"It is zero emissions, there is no carbon," he said. "And hydrogen is the most plentiful element in the universe."
就像Hazen博士指出的那样,碳是宇宙中含量排第四的元素,仅落后于氢,氮和氧。
As Dr Hazen pointed out, carbon is the fourth-most-abundant element in the universe, after hydrogen, helium and oxygen.
虽然含量丰富(除了光子以外,它在宇宙中的含量比所有其他类型的粒子都要多),但要探测到它们却难于登天。
Though abundant (the universe probably contains more of them than any other sort of particle except photons), they are fiendishly difficult to detect.
宇宙在一种神秘的“暗能量”的作用下,分崩离析,不断膨胀;这种暗能量虽然含量极微,却遍布宇宙各个角落。
The universe is expanding, being thrust apart by some mysterious "dark energy", minute traces of which pervade all space.
他说:“它的废气排放量是零,不排放碳,而且氢是宇宙中含量最丰富的物质。”
It is zero emissions, there is no carbon, "he said." And hydrogen is the most plentiful element in the universe.
有证据表明宇宙中锂元素的含量比预计要少,所以假设的超级弱相互作用重粒子可以作为一种方法解释这种差异。
There is some evidence that the universe has less lithium than expected, and the super-WIMP hypothesis is one way to explain the discrepancy.
首先,人们发现这种难以捉摸的粒子具有质量。理论家相信它和光子一样,在宇宙中含量丰富,但是几乎从不与任何物质发生反应。
First the elusive particles, which theorists believe to be as abundant in the universe as photons, but which almost never interact with anything, turned out to have mass.
采用大含量氟利昂气体,用宇宙线测量该探测器的探测效率,输出电荷,时间分辨。
The efficiency, output charge and time resolution were measured by cosmic muons when the detector was operated with F134a rich mixture in avalanche mode.
