查询词典 hydrogen ion

The gaseous impurities in the alloys were well controlled with the sum of C, N and O less than 500wppm. For the first time it was found the strong interaction between Cr-Ti-CON, which reduces the mobility of Ti and CON, enhancing high-temperature strength and the aging-hardening property, and keeping the cold-work induced hardening at higher temperature. Aging-hardening could increase the tensile strength of V-4Cr-4Ti by 30% and could be utilized at 00 C for better economical performane of a vanadium structure. Hydrogen release will occur for the alloys tensile loaded at room temperature, which will affect the safety of a vanadium structure due to the resulting dimensional instability. For hydrogen embrittlement, impact toughness and fracture toughness of the alloy showed higher sensitivity than the tensile test elongation,so the toughness should be used as a new standard for the assessment of the embrittlement. Vanadium alloys were easily oxidized in air.

合金的气体杂质含量得到有效控制，C、N、O总量低于500wppm；首次发现Cr-Ti-CON之间的强相互作用，它使Ti、CON的高温可移动性降低，提高合金的高温强度、增强时效强化特性、使冷加工强化保持到更高温度；时效强化可使V-4Cr-4Ti的强度提高30%，可在低温（00C）下应用，提高构件的经济性；室温下，钒合金在拉应力的作用下，存在着氢释放，带来部件使用中的尺寸不稳定性，影响构件安全；氢脆是钒合金聚变应用的一个关键问题，合金的冲击韧性和断裂韧性表现出比拉伸延伸率更强的氢脆敏感性，应作为评价合金氢脆行为的新标准。

Hydrogen always has valence 1, so other elements' valences equal the number of hydrogen atoms they combine with.

元素的特征价数是以该元素一个原子可结合的氢原子数或可从一化合物中置换出的氢原子数来表示。

One of the challenges with hydrogen production is the cost of compressing and transporting hydrogen from central locations.

氢气生产的所面临的一个很大的挑战是在能源中心压缩和运输氢气的成本问题。

When aeration was applied, hydrogen peroxide increased with the increase of dose until 300 krad.If deaeration before radiation, no hydrogen!

辐照白酒时，过氧化氢随辐照剂量的增加而增加，100krad达最大值，嗣后，随剂量增大而逐渐下降，如果辐照时通入空气，直至300krad辐照，过氧化氢仍在继续增加。

We also try to give a new definition about the AGB stars. We may refer TPAGB stars as homology AGB stars and the second ignition of hydrogen is an appropriate criterion of the HAGB, since after the second ignition of hydrogen, AGB stars have similar properties and structures: a degenerate CO core covered by double thin burning shells.

我们还尝试着给出一个有关AGB星的新的定义，即可以将热脉动AGB星称做相似AGB星，把恒星是否经历氢的第二次点燃看作恒星是否处于相似AGB的判据，因为在氢的第二次点燃之后，AGB星具有相似的性质和结构：一个简并的碳氧核上面覆盖着两层很薄的燃烧壳层。

The results show that 5% nucleating agent,twelve-hydrated disodium hydrogen phosphate,could reduce the supercooling degree of acetate hydroxide trihydrate to some extent but the supercooling degree was still large.However,the supercooling degree of sodium acetate trihydrate could decrease clearly by adding 3% thickener gelatin and 5% twelve-hydrated disodium hydrogen phosphate.

实验结果表明，质量百分比为5%的成核剂十二水磷酸氢二钠能一定程度上抑制无机水合盐三水醋酸钠的过冷度，但其过冷度仍然较大；使用质量百分比5%的十二水磷酸氢二钠和质量百分比3%的增稠剂明胶做添加剂后，三水醋酸钠的过冷性能得到明显改善。
