金属元素

It is a metallic element that is found in the crust of Earth.

这是一种金属元素，存在於地球的地壳。

All of the chemical elements, other than hydrogen and helium, have only about one-tenth the abundances seen in our own galaxy.

所有的金属元素的丰度，只有我们银河系的十分之一。

Said metal nitride is prepared through mixing the aqueous soltuion of nitrate or sulfate of A with the aqueous soltuion of Cr, Mo or W acid or one of their ammonium salts, coprecipitation or impregnation to obtain load-type or non-load-type dual-component metal salt or compound oxide, then pass in NH3, sequentially heating and azotizing at 600-750 deg.C.

该金属氮化物是由含A过渡金属元素的硝酸盐或硫酸盐水溶液与Cr、Mo或W酸或者Cr、Mo或W酸铵水溶液混合，通过共沉淀法或浸渍法制成负载型或非负载型双组元金属盐或复合氧化物，再将双组元金属盐或复合氧化物通NH3进行程序升温，至最终氮化温度600～750℃下进行反应而制得。

The relationships between crusts and substrate rocks have been probed from the following four aspects:(1) the characteristics of major metallic elements content in seawater, substrate rocks and crusts;(2) the different close relations between different bedrocks and crusts by cluster analysis;(3) the distribution characteristics of crusts;(4) the influence of rock types on the growth of crusts.

从以下四个方面探讨结壳与基岩之间的关系：(1)海水、基岩和结壳中主要金属元素含量特点；(2)通过聚类分析方法探讨结壳与基岩之间的亲疏程度；(3)结壳的分布特征；(4)不同基岩类型对结壳生长的影响。

Adding chelations in solution to avoid hydrolyzing before to deal with the etched foils. There are some reasons: to avoid hydrolyzing of the cation in solution, to give facilities for the soakage to the surface of etched foils, to decrease the size of crystals.

由于复合氧化物中的阀金属元素的特殊性质，为保证处理液在工业生产中的稳定性，应尽量将阀金属阳离子单离子化，这样处理有如下好处：避免阳离子在水溶液中水解变性；便于处理液与腐蚀箔的浸润；尽量缩小晶粒尺寸。

Metals listed in the chemical analysis are complexed in the mineral.They do not necessarily exist as the free oxides.

列出的金属元素为矿物中的复合物，并非一定是以自由氧化物的形式存在。

However, the desorbing plateau pressure of the alloys increased and the desorption capacity increased apparently with increasing Cr content.

而随着金属元素Cr含量的增加，合金的放氢平台压力升高，放氢量则明显提高。

The desorbing plateau pressure of the alloys decreased slightly and the capacity of absorption and desorption increased slightly with increasing V content.

而随着金属元素Cr含量的增加，合金的放氢平台压力升高，放氢量则明显提高。

The influence of V and Cr content on the hydrogen storage properties of TiVCr based alloys was investigated. The desorbing plateau pressure of the alloys decreased slightly and the capacity of absorption and desorption increased slightly with increasing V content.

为此研究了钛钒铬基合金中V、Cr含量对贮氢性能的影响，结果表明：随着金属元素V含量的增加，合金的放氢平台压力略有降低和吸放氢量略有增大。

The analysis was performed by subjecting the oil sample to high-voltage plasma which energises the atomic structure of the metallic elements, causing emission of light.

分析应通过把机油样本放入能使金属元素原子层活跃而发出光的高压等离子体中。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
