1. Then in 1925, a team of chemists led by a scientist named Ida Tacke claimed that they had found element 43. 然后在1925年，一个由科学家艾达·塔克领导的化学家团队声称他们发现了43号元素。
2. A person's armpits have all the appeal, and some truffles take advantage of such a human nature—at least to chemists. 一个人的腋窝会产生全部的吸引力，一些块菌就是利用了这样一种人性的特性——至少在化学家看来是这样的。
3. Arrhenius calculated the capability of carbon dioxide to trap heat in the Earth's atmosphere, but other chemists disagreed. 阿伦尼乌斯计算了二氧化碳在地球大气层内的蓄热能力，但是其他化学家对此有异议。
4. The chemists did find small amounts of the three remaining suspected chemicals but pointed out that these occur naturally in all canned foods. 化学家们确实发现了少量残留的三种可疑的化学物质，但他们指出这些化学物质在所有罐头食品中都会自然产生。
5. Both chemists were sufficiently farsighted to leave gaps where their analyses of periodic physical and chemical properties indicated that new elements should be located. 这两位化学家都非常有远见，他们对周期性的物理性质和化学性质进行分析，并在预示应该出现新元素的地方留下了空位。
