查询词典 helium

The conclusion made in the paper provides a technical support for the design of instrument of in-rod helium pressure scatheless measurement.

为了防止氦气泄漏造成的包壳内压力降低，威胁到反应堆的安全，就有必要对燃料棒进行进堆前氦气压力无损检测。

scatheless measurement ; numerical simulation ; helium pressure

利用氦气在不同压力下具有不同的状态参数和热力参数，可以通过传热方法测量包壳内的氦气压力。1试验装置和研究方法如图1，把燃料棒浸入到一个高温的池子内，热量会在燃料棒内传递开来，通过测量管壁外面不同位置出的壁面温度，就可以推测到包壳内的氦气压力

For an hour or so, the homemade silver foil or mylar-coated helium balloon floated high above the countryside in southern Colorado State.

大约1个小时的时间，这个自制的用银箔或聚酯薄膜包膜的氦气球一直高高的漂浮在科罗拉多南部乡村的上空。

And looking back on his own academic work he showed a certain solidarity with his subject's sloppiness:"I'm very grateful that the isotopic composition of helium has not become a key matter of public interest."

回顾他自己的学术研究时，他表达了一些对其调查对象马虎的同袍情，"我很庆幸氦的同位素组成这研究没受到大众关注"。

Slick Smitty entered the annual forest marathon race with helium balloons tied to his body.

斯力克。斯密提参加了年度森林马拉松比赛，他把氦气球系在自己身上。

3He is one stable isotope of helium, which is expensive because of its sparsity.

摘要氦-3是氦的稳定性同位素之一，十分稀缺昂贵。

Based on them, we calculated precisely some enegy levels of P-wave and D-wave of a helium atom, presented and proved the general interdimensional degeneracies for a quantum N-body system, derived the general spherical spinor functions and the exact solution to the Dirac equation for the hydrogen atom, and proved uniformly the Levinson theorem for the Dirac equation in D-dimensions.

在此基础上，我们精确计算了氦原子P波和D波若干较低能级，建立和证明了量子N体系统不同维数状态间最普遍的简并，推导出任意 D 维空间广义球旋函数和Dirac方程氢原子的精确解，统一地提出和证明了任意 D维空间Dirac方程Levinson定理的一般形式。

Gravity from the larger white dwarf slowly pulls helium from the surface of its neighbor, and the siphoned gas builds up into a shell around the star.

从较大的白矮星重力缓缓进站从邻国表面氦，而抽走瓦斯积聚成空壳了围绕恒星。

Their shells, which apart from hydrogen, helium, and carbon also contain portions of the heavy elements formed in the stellar core, are inherently unstable, and their pulsing creates a withering stellar wind a billion times stronger than the solar wind we know today.

它的壳层除了氢层、氦曾和碳层外还有包含一部分产生自恒星核心的重元素，天生的不稳定，它们的脉动产生了一种毁灭性的星风，比我们现在知道的太阳风要强数百万倍。

With the decreasing of the immersion depth, different kinds of boiling modes appear in the superfluid helium II.

在超流氦的沸腾实验中，随着静压液柱的降低，会出现不同的沸腾状态。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
