A radioactive transuranic metallic element; produced by bombarding plutonium with helium nuclei.

一种放射性超铀元素，在用氦核子轰击钚时发现。

The argon-helium knife is no a real knife, actually it is a kind of apparatus like trocar, isn't it?

这个氩氦刀其实它不是一种刀，是一种象导管一样的装置，是吧？

Uranian atmosphere, by composition, is 83% hydrogen, 15% helium and 2% methane although traces of other hydrocarbons have been found.

天王星大气的组成，是83％的氢，15％的氦和2％的甲烷等碳氢化合物虽然已发现的痕迹。

A mineral consisting of uranium oxide and trace amounts of radium and thorium and polonium and lead and helium; uraninite in massive form is called ''.

一种含有氧化铀和少量镭、钍、钋、铅、氦的矿物；块状的晶质铀矿称为沥青铀矿，是主要的铀矿石。

This design reduces heat leak and vaporization of liquid helium during transportation .

这种设计减小了运输过程中的热泄漏和液氦的蒸发。

At higher pressures, six-body effects become significant, and the inclusion of its contribution can extend the theoretical prediction from 60 to 180 GPa, where the empirical Vinet EOS give a lower prediction by 6-14%.

结合双原子势能函数，证明了单原子对体系总势能贡献分量的计算公式E=1/2[β~2U_2+(1-β~2)V_n]，对于高压氦体系，其中待定参数β的取值约0.5。

Using He as working substance, the pulse tube refrigerator reaches 160 K at the cold end and achieves

利用氦气作工质，脉冲管冷端最低温度达160K，每1K有0.75W的制冷量。

The results show that the angular distribution of the total differential cross section at zero degree increases and the position of oscillation minimum of the same order gradually shift towards small scattering angle along with the increase of the incident isotope He atom mass at identical collision energy. And crossing angle between the elastic and total inelastic DCS gradually decreases and the total inelastic DCS gradually increases.

结果表明：在相同碰撞能量时，随着同位素氦原子质量的增加，总微分截面在0°时的角分布逐渐增大，同一级衍射振荡极小值位置逐渐向小散射角方向移动；弹性与总非弹性截面交界角逐渐减小，总非弹性截面逐渐增加。

A protective atmosphere in the production of reactive metals, such as titanium and zirconium.

在活泼金属，如钛和锆的生产中，氦可以提供保护性气氛。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
