1. The toughness, lightness, strength, and elasticity of whalebone gave it a wide variety of uses. 鲸须的坚韧、轻巧、结实而又有弹性赋予它广泛的用途。
2. According to the public, at least, it's not that they lack toughness, management talent or proper skill sets. 至少在公众看来，这并不是因为他们缺乏韧性、管理才能或是与之匹配的技能。
3. Now, though, a novel type of steel has been developed that resists fractures at much lower temperatures, while retaining its strength and toughness—without the need for expensive additives. 然而现在，一种新型的钢已经被开发出来，它可以在更低的温度下抵抗断裂，同时保持其强度和韧性，而不需要昂贵的添加剂。
4. The resulting steel appears to achieve a combination of strength and toughness that is comparable to that of modem steels that are very rich in alloy content and, therefore, very expensive. 产出的钢在强度和韧性方面的综合性能可与合金含量非常丰富的现代钢相媲美，因此价格非常昂贵。
5. The resulting steel appears to achieve a combination of strength and toughness that is comparable to that of modern steels that are very rich in alloy content and, therefore, very expensive. 由此产生的钢似乎达到了强度和韧性的结合，这与合金含量非常高因而非常昂贵的现代钢相当。
