含金属的

The results suggest that the electronic π-π* transitions in AlQ_3 are localized on the quinolate ligands; the transition from a phenoxide donor to a pyridyl acceptor includes C→C and O→N transferences. There hardly is any relation to the metal aluminum.

结果表明，电子从基态跃迁到低激发态时主要为π-π*跃迁；电荷从含氧的苯酚环转移至含氮的吡啶环上，包括两环之间 C→ C转移和 O→ N转移，与金属离子关系不大。

The scrap metal are steel, ferreous and non ferreous. the grade of the steel I dont have the exact classification. If I have to class them, then we would have more time consuming and it will cost more money to seperate them.

钢的、含铁或不含铁的废金属，我们没有精确的划分等级标准，如果我们去划分它们，我们将花费大量的时间，并且会浪费很多钱来区分他们。

A direct smelting process and a fixed, ie non-rotatable, metallurgical vessel for producing metal from a metalliferous feed material is disclosed.

本发明涉及用于从一种含金属喂入材料制造金属的一种直接熔炼工艺和一种固定的即非转动的冶金容器。

Through the addition of rare earth oxidation La_2O_3 and CeO_2 into the electrode coating , the effect of rare earth oxidation on high temperature oxidation and sulphidation resistance is studied and the rational addition amount is suggested.

通过A402，A302，A202及Cr24Ni7不锈钢焊条熔敷金属的抗高温氧化腐蚀性能对比试验分析，设计了新的专用焊条合金系统Cr26Nil6，并在焊条药皮中分别添加微量稀土氧化物La2O3及CeO2，研究不同稀土氧化物添加量对焊条熔敷金属在空气中和含硫气氛中抗高温氧化及腐蚀性能的影响，从而确定了合理的稀土氧化物加入量。

The mathematical method for calculating the infinite oscillating integration with complex argument modified Bessel functions is discussed. The borehole correction charts of the coils with metal mandrel are given.

给出了含复宗量变型Bessel函数无穷限振荡积分的数值计算方法和含金属心棒线圈系的井眼校正图版。

The metal-bearing rock can also show large dielectric enhancement when the metal particles are coated by low conductive membrane.

对于含金属颗粒的岩石模型，如果金属颗粒表面存在低电导率膜层，该介质就会在低频端出现很大的介电增强。

Putting the contaminated scrap into the bath directly without preheating and pyrolysing will increase the metal loss by oxidation, because the contaminants are containing oxygen, which will react with liquid aluminium immediately.

将含杂质的废铝在未经预热和热分解的情况下直接加入到熔池中会增加金属的氧化损失。因为杂质中含氧，直接加入到铝液中，会立刻与铝液发生反应。

Its preparing process includes dissolving the salts containing metal in group VIB or VII or their mixture in ammonia water until full dissolving, and adding citric acid to stabilize the solution.

其制备方法为：先用氨水溶解含ⅥB族金属或Ⅷ族金属的盐，或二者混合物，使之完全溶解后，加入柠檬酸以使溶液稳定。该溶液稳定性好，制备过程快速、简便、节能。

The metallicity excess could result from either the accretion of planets/planetesimals on to the star or the protostellar molecular cloud.

含金属过多是由行星/行星原质或原始恒星分子云的吸积引起的。同时，这种过金属性质也表现在类太阳&有行星&恒星中（参见图表2c）。

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。
