氦

Based on the helium isotope composition of eclogites, some ofthose problems are discussed in this paper.

本文通过对该地区榴辉岩的氦同位素研究对上述问题进行探讨。

Measurements can be performed in a vacuum or helium atmosphere.

测量可在真空或氦气氛中进行。

If we have reached the Helium pressure the time T18 starts.

如果我们达到了氦气压力，时间T18就开始了。

We have an anomaly in a helium pressure system valve.

我们有一个系统阀门氦压力异常。

The experimental environments are selected as helium and air.

试验的环境气氛为氦气和空气。

We have three days at best till the helium leaks out of those balloons.

我们最多有3天，直到那些气球里的氦泄漏出去。

China mainly natural gas used in the production of nitrogen, followed by the production of methanol, formaldehyde, acetylene, methylene chloride, carbon tetrachloride, carbon disulfide, nitromethane, hydrocyanic acid and extraction of helium and carbon black. Since the 70s, has built more than natural gas and oil field associated gas as raw materials for large-scale ammonia plant, as well as a number of small and medium-sized ammonia plant, so that the national structure of the synthetic ammonia production of raw materials, natural gas share of about 30%; also be built at the same time A system of acetylene gas plant to manufacture Vinylon and vinyl acetate, acetylene gas used in the production of methanol.

中国天然气主要用于生产氮肥，其次是生产甲醇、甲醛、乙炔、二氯甲烷、四氯化碳、二硫化碳、硝基甲烷、氢氰酸和炭黑以及提取氦气。70年代以来，已兴建多座天然气和油田伴生气为原料的大型合成氨厂，以及一批中、小型合成氨厂，使全国合成氨生产原料结构中，天然气所占的比例约达到30％；同时还兴建了天然气制乙炔工厂，以制造维尼纶和醋酸乙烯酯，乙炔尾气用于生产甲醇。

Angular distribution for scatterings of 3He、4He、6He and 7He with hydrogen bromide molecules are calculated by using close-coupling approach from the anisotropic intermolecular potential of the He-HBr system established by the author. The calculations are performed separately at the collision energies of 60 and 100 meV. The influences of He isotope atoms on angular distribution is discussed in detail.

基于作者构造的He-HBr体系的各向异性势，采用密耦方法计算了碰撞能量分别为60和100 meV时3He、4He、6He和7He被HBr分子散射的角分布，详细讨论了氦同位素对散射角分布的影响。

They who in the obedience attain to the greatest height which is possible in this life, are so far from being able to excel, and to do more than God requires, as that they fall short of much in duty they are bound to do.

When other modalities become inefficacious, Argon-helium knife still can get very good results.

其它方法都无效的情况下，氩氦刀依然取得非常好的效果。

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。
