金属的

"These metals are similar chemically because their atomic structures are generally similar; all form compounds in which they have valence 3, including stable oxide s, carbides, and borides."

这些金属的化学性质十分相似，因为它们的原子结构通常相似；它们都可以与其它元素形成化合物，包括稳定的氧化物、碳化物、硼化物，它们在其中的原子价为3价。

Through reviewing the reproductive toxicity of some major environmental chemical pollutants, including endocrine disrupters, organic phosphor and chlorine pesticides, organic solvents, and some metals such as lead, cadmium, mercury, manganese, the paper finds that all these ECPs have different extents of toxic effects to experimental auimals on procreation, gestation and even on offspring, some of which have been evidenced by the population epidemiological studies.

本文通过对邻苯二甲酸酯类和双酚A等内分泌干扰物、有机磷和有机氯农药、常用有机溶剂以及常见金属的生殖毒性研究的综述，发现它们均在不同程度上造成对实验动物的生殖毒性、妊娠毒性以及对子代的毒性影响，其中部分在人群流行病学研究上得到证实。

The heat of fusion welding is generated in several ways,depending on the sort of metal which is being welded and on its shape.

熔焊的热度有几种来源，取决于被焊金属的种类及其形状。（注重的是翻译出语言的简练

Anyone who has children will be familiar with aluminisedparty balloons. Such balloons are made from metal-coated plastic.

任何家有小孩的人对铝膜晚会气球都不会陌生，这样的气球是使用涂有金属的塑料制作的。

Hardness of a metal is its resistance to surface indentation or penetration under standard test conditions.

一种金属的硬度是它的抵抗表面凹口或者在标准测试条件下的洞察力的能力。

They were chosen in this study to calculate the molecular geometries, electronic structures, and IR spectra of a series of Pcs having different centers or/and different substituents on the benzene rings. CPHF and ZINDO are the most popular methods to study the non-linear optical and excited state properties, respectively.

ZINDO和CPHF分别是计算激发态和NLO极化率的最常用方法之一，本文用ZINDO计算了部分化合物的激发态，得到了紫外可见光谱图，用CPHF/3-21G方法研究了近20个不同取代基和不同金属的菁化合物的NLO性质。
