They feature increased chromaticity, higher color purity and more brightness and hiding power than traditional non-metallic metallic colors.

它们具有高彩度、高颜色亮度的特点，提供强烈鲜艳的金属颜色效果。

The results show that quartz cannot react with oleic irons at pH=8-10, because it is difficult to combine with metallic irons. On the contrary, clinochlore can adsorb with oleic ions because there are enough active metallic positive ions between the minerals layers which can combine with clinochlore. The clinochlore can be hydrophobic, and so the separation can be realized finally. At pH=9, the clinochlore removal rate is the maximum, the purity of SiO2 is 99.86%, and the recovery of SiO2 is 35%.

结果表明：在pH为8~10的碱性溶液中，粉石英难与金属阳离子缔合，所以，不与油酸根离子结合；而斜绿泥石解离后层间存在活性金属阳离子，可与油酸根离子发生化学吸附产生疏水作用，因而使用反浮选的方法能有效地实现二者的分离：当pH为9时，斜绿泥石的去除率最高，粉石英的纯度达99.86%，回收率为35%。

In order to ensure the safety of the metallic wires in use, it's essential to analyze the causation of metallic wire's damnification and offer some improving approaches.

为了确保使用中钢丝绳的安全运行，分析钢丝绳的损伤原因及改进措施很有必要。

NO elimination reactions are much complicated in the system of NO-CO-CO2-N2 with the existence of metallic oxides. Homogeneous reaction between NO and CO, reduction of NO by the lower valued metallic oxides, direct decomposition of NO as a catalytic reaction and catalytic reaction of NO/CO may all contribute in NO elimination.

金属氧化物存在条件下NO-CO-CO2-N2体系中，NO去除反应较为复杂，NO/CO气相直接反应、低价氧化物对NO的还原作用、金属氧化物对NO分解反应的催化作用及金属氧化物对NO/CO反应的催化作用等都可能存在。

Electrical oscillations in a metallic "sending coil" radiate inductive photons toward one or more "energy-magnifying coils" comprised of a photoconductor or doped semiconductor coating a metallic conductor, or comprised of a superconductor.

电气振荡的一个金属"发送线圈"辐射感应光子对一个或一个以上的"能源-放大镜线圈"组成的一个光导体或掺杂半导体涂层的金属导体，或组成的超导。
