It was found that increasing temperature contributes to the coalescence of helium clusters.

研究发现，温度的升高会加快氦团簇的融合。

The coalescence of helium clusters has been investigated in great detail in a range from 300 to 800K.

在300—800K的温度范围内，模拟了钛基底中氦团簇之间的融合过程。

The coalescence of helium clusters has been investigated in great detail in a range from room temperature to 800 K.

At the eclipses of 1868 and 1869, observed from Siam and from the United States, respectively, the first coronal emission line was detected: about 25 years later, it was said to be from the element 'coronium', by analogy with the prior discovery of helium.

1868-1869的一次日蚀期间，观测者由泰国和美国分别观测，第一个日冕射线被检测到，大约25年后，被证实来自元素"coronium"，于氦的发现类似。

Then director Pete Docter ties a bunch of helium-filled balloons to Carl's dead-end life, sending the crotchety old man and a feckless young interloper to South America for a lesson in what constitutes a life of adventure.

然而，导演皮特道格特以一束氢气球，卡尔的死亡为线索，告知一个古怪的老人和一个无能的年轻人在南美洲，什么是冒险的生活。

The stability of a liquid helium free superconducting magnet could be analyzed using the adiabatic stability criterion because there is no cryogen in the system.

制冷机直接冷却的超导磁体，没有冷却介质，因此，用绝热稳定化判据分析其稳定性是合适的。

It was found that the main source of uncertainty in the system is the additional noise from the movement of the frozen flux by the pressure fluctuation in the cryostat, which disturbs the system during the dynamic process. Thus a new type of helium gas filter was designed to solve this problem.

并通过对低温电流比较仪系统及运行过程的研究，发现了氦气气压波动引起的冻结磁通蠕动导致的附加噪声是限制系统不确定度的主要原因。
