查询词典 helium

In 2004, Professor Chan received international attention for his discovery of a new phase of matter -- a supersolid form of helium-4 with the remarkable properties of a superfluid.

二零零四年，他发现物质新位相──氦气4超固体形式中有超流体的特质，引起国际注目。

A metastable helium atomic beam effused out of atom source is firstly cooled transversally by laser. This well-collimated atomic beam traveling through the light standing-wave whose direction is perpendicular to atomic beam is quenched, and channeling effect happens in atomic density distribution.

亚稳态原子束从原子源喷出后首先对其进行横向激光冷却，准直后的原子束穿过与之垂直的激光驻波场时发生淬火过程，原子的密度分布出现沟道化效应，给出基于光掩模制作纳米图形的基本原理、理论分析及模拟结果。

Indicates Main Propulsion OXID, FUEL and HELIUM quantity.

As the two fight, Jen suddenly floats up, as if on the helium of her young arrogance, and canters up and down the courtyard walls, with Shulien in urgent pursuit.

当俩人在打斗时，玉娇龙忽然腾空而起，像是在驾御自己的年轻傲气，在庭院墙上忽上忽下，而俞秀莲在后面紧追不舍。

Even though helium atoms are four times chunkier than hydrogen atoms, they are still small enough to find all the weak spots as they worm their way through the crystalline structure of solid steel several centimetres thick.

即使氦原子比氢原子的体积大四倍，当他们缓慢的通过几厘米厚的晶体结构的脱氧钢时，它们还是足够的细小能检查出所有的裂缝。

Klein continued,"Perhaps it is the absence of great issues, great crises; perhaps it is simply the absence of suffering—but baby-boom politicians, even in middle age, still seem like helium-filled dilettantes."

Joe Klein还补充说：&也许是因为他缺乏大事的体验，困苦的磨折；出生于婴儿潮的政治家即便到了中年，看上去还像是一知半解的门外汉。&

Structural materials in fusion reactor are easily embrittled by He atoms produced from α particles and neutron irradiation, resulting in the degradation of stability and safety in nuclear facilities. Thus, it is necessary to improve the ability of helium embrittlement resistance in materials.

聚变堆结构材料极易因α粒子和中子辐照引入大量的He原子而脆化，降低核设施的稳定性和安全性，因此，必须提高材料的抗氦脆能力。

These so-called dark stars, named for the song "Dark Star" by the Grateful Dead , would contain mostly normal matter, in the form of hydrogen and helium molecules, but would be vastly larger (about 400 to 200,000 times wider) and "fluffier" than the sun and other stars.

这些所谓的暗恒星，是根据&感恩而死&乐队创作的歌曲《暗恒星》命名的。暗恒星中所包含的主要是普通物质，以氢分子和氦分子的形式而存在。但是暗恒星比太阳和其他恒星要大得多（大400倍至20万倍），密度也要低得多。

Objective To observe the change of macrophages in peritoneal cavity, immune function, and TNF-α in peritoneal fluids after a pneumoperitoneum with insufflating carbon dioxide (CO2) or helium in rat model, investigating the effects of different gases on peritoneal local immunity.

目的 研究二氧化碳(CO2)、氦气在模拟气腹条件下，动物模型腹腔巨噬细胞的数量、免疫功能和腹腔液中肿瘤坏死因子－α含量的变化，探讨不同气体对机体腹腔内局部免疫的影响。

Solvents are normally degassed before pumping by sparging with helium, sonication or using on-line membrane/vacuum modules to avoid the creation of gas bubbles in the detector cell.

溶剂被抽之前，通常用氦气鼓泡，超声波或使用再线膜/真空组件来去除气体，以避免检测池中气泡的产生。

He and Nina moved to California and lived at 2005 Ivar Street, Apt.
