查询词典 metallic

From the structural analysis of three praseodymium complexes, we could draw a conclusion that as the dentate arms of carboxyl group on ligands elongating, the coordination numbers of Pr and the coordination modes of ligands increase, and the mean distances between metallic atoms of metallic helices existing in these complexes augment.2.

Using silicon and metallic iron,α-Si_3N_4 olivary microparticles with a diameter of about 300～500 nm have been obtained at 650℃.When silicon and metallic aluminium were used to react with ammonium chloride,α-Si_3N_4 nanowire bundles with diameter of about 8 nm can be also obtained at 600℃.Since all of the starting materials used are relatively cheap,the methods will have potential prospect in industrial application.3.Graphite-like carbon nitride nanowire bundles with diameters of 200-500 nm were synthesized from the solid state thermolysis of melamine at relatively low temperature(400℃).

The mechanism of abnormal swelling caused by CaO is that Ca(superscript 2+) in crystal lattice of iron oxide accelerates the formation and growth of metallic iron whisker during the reducing procedure from wüstite to metallic iron giving abnormal swelling.

对CaO导致球团异常膨胀的机理进行了探讨：在浮氏体还原成金属铁的过程中，固溶于铁氧化物晶格中的Ca(上标 2+)会促进&铁晶须&的生成与发展，导致球团产生异常膨胀。

In the course of reduction at about 1000℃,Fe_2O_3 and then Fe_3O_4 was almostcompletely transformed into Wüstite within a few minutes prior to the formationof metallic iron;but the reduction of Wüstite to metallic iron lasted a much lon-ger time.

在1000℃左右的还原过程中，在金属铁出现之前，在数分钟内Fe_2O_3和Fe_3O_4几乎都已全部还原成浮士体，但后者还原成金属铁的阶段，则须经历数十分钟之久，因此后一阶段便成为还原过程中控制的一步。

In the course of reduction at about 1000℃,Fe_2O_3 and then Fe_3O_4 was almostcompletely transformed into Wüstite within a few minutes prior to the formationof metallic iron;but the reduction of Wüstite to metallic iron lasted a much lon-ger time.Therefore the last stage reaction controls the whole reduction process.
