1·In one case, executives discovered a coating advertised as pure gold that masked a complex alloy, which included rare metals such as osmium, iridium, ruthenium and rhodium.
在一个案例中，业内高管发现一种号称纯金的涂层其实是一种复杂的合金，含有锇、铱、钌、铑等稀有金属。
2·Increasingly, rhodium and ruthenium are being plated over more traditional contact materials to increase the contact life.
逐渐地，铑和钌被镀在传统的接触材料上来延长触点寿命。
3·Because the ruthenium may be subject to photodegradation, the total exposure to the excitation energy should be minimized.
因为光降解影响钌，对激发能总的外露面积应当最小化。
4·This metal complex's core element is ruthenium.
这金属配合物的核心要素是钌。
5·Polypyridyl ruthenium complexes play an important role in the research fields such as photophysics, electrochemistry and DNA structure probes.
多吡啶钌配合物在光物理、电化学、核酸结构探测等研究领域占有重要的位置。
