查询词典 helium

Helium balloon in the floating line about 80 kilometers, two hours later landing on their own, but did not see the trace of Falcone.

氦气球在飘行大约80公里、两个小时后自行降落，但没有见到法尔科内的踪影。

Followed by a ground rescue personnel search, but the end result thing is that Falcone does not climb into the helium balloon, he has been hiding for fear of his father blamed the home loft.

救援人员随后展开地面搜索，而事情最终结果是，法尔科内并未爬进氦气球，他因害怕父亲责备一直躲在家中阁楼内。18日，治安官吉姆。

A homemade helium balloon that broke free of its moorings in the United States, reportedly with a 6-year-old boy inside, has landed in a field after a flight across the Colorado countryside.

一自制的氦气球在美国挣脱了下锚处，据报有一位六岁的小孩在其上，该气球在非越科罗拉多州乡间后已降落。

Also calculated are dynamic heat transfer characteristics in the fuel rod under different pressure and it is found that we can use the temperature raising speed at x=14.5 cm to calculate helium pressure in the fuel rod.

通过用RODTRAN程序计算各种不同压力情况下的燃料棒动态传热特性，发现利用x=14.5cm处的包壳表面升温速率可以推算燃料棒内的氦气压力，氦气压力的测量精度可小于5％，也就是说可以区分1.9MPa和2.0MPa的压力差别，此时的最大温差可达0.5℃，同时也发现压紧弹簧段的温度响应比铀芯块段要快。

In the early 1950s American scientists produced the hydrogen bomb by inducing fusion reactions in a mixture of the hydrogen isotopes deuterium and tritium, forming a heavier helium nucleus.

1950年代，美国科学家在氢的同位素氘和氚的混合物中引导聚变反应生成较重的氦原子核，从而制造出了氢弹。

Based on the preliminary design of fusion reactor ,aiming at the outline of solid blanket design,an advanced helium cooled solid blanket concept was developed.

在聚变堆初步概念设计的基础上，针对固态包层设计路线，提出了一个先进的氦冷固态包层概念。

To solve these problems, we must make it clear that: why helium could state in these materials; what disadvantages whill bring to the performance of these materials by these processes; what the influence factors of these processes and how we could control them. These problemes were came up from metaphase of 20th century, and that from 1970s, with the design of fusion reactor and the research development of its materials, we make it sure that these problems must be solved firstly.

为了解决这些问题就需要搞清楚：氦在材料中为什么能够滞留，在什么情况下会聚集、扩散及释放出来；这些过程对材料性能有什么害处；它受什么因素影响以及如何控制它等等。20世纪中期这些问题就已经被提出来，而从70年代开始，随着聚变反应堆的设计和聚变堆材料研究的进展，更加明确它是一个需要解决的难题。

For example Helium, which we typically engage in its gaseous form.

以氦气为例，一般我们接触的是气态的。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
