查询词典 calaverite

The monocrastal minerals of gold are native gold, calaverite and electrum. Besides the native gold, pyrites and pyrrhotites are main auriferous minerals, inside which the aurum are in the form of fracture aurum, intercrastalline aurum and aurum inclusions.

Au的独立矿物主要为自然金、碲金矿和银金矿，金除了自然Au之外，黄铁矿和此黄铁矿是主要载金矿物，在载金矿物中Au主要呈裂隙金、晶间金和包体存在。

From mineral associations ofnative gold -calaverite, ga1ena -altaite in conunon, and native silver-hessite at the endof the sulfides quartz stage, it is concluded that Te, fugacity is in "unstheated statefor native Te" and will decline with the temperature of metallogeulc fluids decreased.

自然金-跨金矿、碲铅矿-方铅矿与晚阶段碲银矿-自然银共生组合分析表明，本区碲逸度处于&自然碲的不饱和&状态，并随成矿温度降低而减小。

Most of thesete1lurites and tellurates in these deposits are found to be products of coeval oxidationof calaverite, altaite and sufides, by Which "refractory gold" of Au tellurides will bereleased as naive gold. Most native gold released through oxidation of tellurides,however, will be trapped in the telluraes or tellurites; or be combined by Te intellurites or tellurates, which prevent gold of hyPergene from secondaxy enrichmentunder the supergene oxidation environrnenis.

研究表明，这些碲含氧盐大多数为碲金矿、碲铅矿与硫化物共同氧化的产物，&难溶金&矿物在氧化条件下发生分解，一般释放出自然金；由于金要么以自然金形式被&捕获&于这些含氧盐，要么重新与碲形成Au－Te含氧盐，所以抑制了金的次生富集。

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。
