Now physicists believe that they have detected activities related to a fifth physical force, originating from the helium atom.
然后氦会爆发爆发,并在整个脉冲星表面释放出热核火球。
Then, the helium erupted in an explosion and released a thermonuclear fireball across the entire pulsar surface.
我很担心她――如果你不习惯氦气,呼吸很长时间会很痛,她需要回到地下。
I was worried for her- if you weren't used to the helium it was painful to breathe for very long, she needed to get back Underneath.
在太阳核心区氢转化为氦,而这些量的改变很慢。
In the Sun's core, hydrogen is converted to helium, so these percentages change slowly over time.
我们会用氦气球把模型送到35公里高的平流层。
We will send our model on a helium balloon into the stratosphere at a height of 35 km.
氦核的闪光产生了一系列不同的波,在恒星中传播。
A Helium flash will cause a series of different waves moving out through the star.
然后氦爆炸喷发,并在整个脉冲星表面释放出热核火球。
Then, the helium erupted in an explosion and released a thermonuclear fireball across the entire pulsar surface.
然后火球迅速冷却,氦又重新回到脉冲星表面。
The fireball then quickly cools, and the helium settles back onto the surface.
一杯氦2自发地流动起来,从容器中流泻出来,就好像它自己决定离开一样。
Cup of helium spontaneously flow up, pouring out from the container, as if it were to decide to leave the same.
剩下的大多聚合成了氦以及极少量的锂和其它轻元素。
The rest had fused mostly into helium with traces of lithium and a few other light elements.
当氦熔化时,碳和氧被形成,核心的温度再次上升。
As the helium fuses, carbon and oxygen are formed and the temperature of the core rises yet again.
这种方法告诉研究人员如果氦运动速度足够快逃离地球。
This measure tells the researchers if the helium is moving fast enough to escape from the planet.
在太阳焦点区氢转化为氦,而这些量的改变很慢。
In the Sun's core, hydrogen is converted to helium, so these percentages change slowly over time.
氦膨胀得更快,在氢层消散之前就超过了氢层,然后变慢,停止并沉降回到脉冲星表面。
The helium expanded faster, overtook the hydrogen layer before it could dissipate, and then slowed, stopped and settled back down onto the pulsar's surface.
年9月1日,氦气储罐在发射前测试中爆裂,导致爆炸。
The helium tanks were ruptured in a pre-launch test on Sept. 1, 2016, causing an explosion.
氦核的闪光产生了一系列不同的波,在恒星中传播。
The helium core flash produces a series of different waves that propagate through the star.
我们可以问,如果它来自氦原子或氖原子有什么不同,例如,“他说。
We can ask how is it different if it came from a helium atom or a neon atom, for instance,” he said.
尽管氢原子能够快速电离并响应多种力,但氦原子的运行路径很大程度上受太阳重力的控制。
While hydrogen atoms quickly ionize and respond to numerous forces, the helium atoms travel paths largely governed by the sun's gravity.
虽然氦被包含在电浆内,但是中子具有中性电荷,并且射进围绕电浆的'毯子(blanket)'里。
While the helium is contained within the plasma, the neutron is has a neutral electric charge, and shoots off into the'blanket' surrounding the plasma.
由于氦标志出现在红外波长不被地球大气吸收,它可以通过地面望远镜和卫星进行研究。
Because the helium signature appears at infrared wavelengths that aren't absorbed by Earth's atmosphere, it can be studied by ground-based telescopes as well as satellites.
