Even 15 billion years or so after the big bang , echoes of that event still linger in the form of background radiation , only a few degrees above absolute zero 原始大爆炸已过了150亿年左右,大爆炸的痕迹仍以背景辐射的形式存留在宇宙中间,只比绝对零度高几度。
The cold of interstellar space , thousands of degrees below freezing point or the absolute zero of fahrenheit , centigrade or raumur : the incipient intimations of proximate dawn 星际空间的寒冷,冰点以下几千度或华氏摄氏或列氏的绝对零度194 ,即将迎来黎明的最早兆头。
The universe is being bathed in an extraordinary uniform microwave light which translates into a frigid average of 2 . 73 kelvin degrees above absolute zero , or - 273 c 宇宙万物其实皆沐浴于一种微波辐射之中,它代表著平均只有2 . 73绝对温度绝对零度即摄氏- 273度的冰冷空间。
Even fifteen billion years or so after the big bang , echoes of that event still linger in the form of background radiation , only a few degrees above absolute zero 即使在宇宙大爆炸发生大约150亿年之后,大爆炸的遗迹仍以背景辐射的形式存在于茫茫宇宙之中,这背景辐射只高出绝对温度几度。
Even 15 billion years or so after the big bang , echoes of that event still linger in the form of background radiation , only a few degrees above absolute zero 宇宙大爆炸在一百五十多亿年后的今天仍余波未平,爆炸当时所释放的能量(即使这些能量看起来似乎微不足道)仍以背景辐射现象的形式存在着。
Consequently , the first chip - trap proposal , put forward by a group at the california institute of technology in 1995 , involved cooling the entire chip to near absolute zero using a bulky and expensive liquid - helium refrigerator 所以, 1995年加州理工学院的一个小组首度提出晶片阱的构想,需要用庞大且昂贵的液态氦冷冻机,将整个晶片冷却到接近绝对零度。
The heart of the 3 . 5 - tonne satellite is a container holding four spheres the size of ping pong balls that will be chilled to near absolute zero and spun 10 , 000 times a minute , making them the most accurate gyroscopes ever built 这个3 . 5吨的人造卫星核心部分是一个装有4个乒乓球大小的圆球的容器,这些小球可以被冷冻到绝对零度并能每分转10000转,这些都使这个装置成为建造过的最精确的陀螺仪
She has cooled them just shy of absolute zero ( - 459 degrees fahrenheit ) and observed their funky quantum doings , leading the way into an unexplored realm that holds implications for superconductivity ? the creation of resistance - less electrical flow 她将它们冷却至接近绝对零度,观察到它们诡异的量子行为,为一个未经探索的领域开辟了一条道路,那里蕴涵了超导的奥秘,材料的电阻可骤降至近乎零。
The theory stated that at temperatures near absolute zero , the atoms could reach a state of such low energy that they collapsed into a new state where it was no longer possible to distinguish between them - a state known as einstein - bosecondensation 这项理论预测在几乎处于绝对零度的温度下,气体原子的能量非常低,以至于它们会分解,形成一种新的状态,在这种新的状态下,原子和原子之间无法再区分开来。
From there the antiprotons go into a " catching trap , " where most of their remaining energy is absorbed and radiated away by electrons swirling in a magnetic field , lowering them to a temperature of about 15 degrees above absolute zero and speeds of a few hundred feet per second 从那里反质子进入一个“捕获线圈, ”在一个磁场中它们中的大多数以能量被吸收而且以电子涡流辐射掉了,降低它们的温度为绝对零度上大约15度且速度为每秒数百英尺。
(cryogenics) the lowest temperature theoretically attainable (at which the kinetic energy of atoms and molecules is minimal); 0 Kelvin or -273.15 centigrade or -459.67 Fahrenheit
百科解释
Absolute zero is the coldest possible temperature. More formally, it is the temperature at which entropy reaches its minimum value.
