Polycrystalline tungsten (W) and four kinds of tungsten alloys were exposed to pure and impurities seeding deuterium (D) plasma to investigate the deuterium retention behaviour. The results show that D retention in W increases with the increasing fluence and incident energy, and decreases with the increase of temperature. The doping of alloying element and compounds, such as Re, La₂O₃, and ZrC, suppress the D retention at lower fluence but has limited effect at fluence above 2.6 × 10²⁵ D/m², and D inventory in these W alloys is higher than in W at temperature of 800 K. Helium (He) and nitrogen (N) impurities seeding significantly reduce D retention in tungsten. And higher N content in plasma causes more obvious reduction of D inventory. But the argon (Ar) impurity seeding leads to the increase of D retention.

将多晶钨（W）和四种钨合金暴露于纯净和杂质注入氘（D）等离子体中，以研究氘的保留行为。结果表明，D在W中的保留率随着通量和入射能的增加而增加，而随温度的升高而减少。合金元素和化合物（例如Re，La ₂ O ₃和ZrC）的掺杂会抑制较低通量下的D保留，但对通量大于2.6×10 ²⁵ D / m ^2的影响有限在800 K的温度下，这些W合金中的D存量要比W中的存量高。血浆中较高的N含量会导致D存量的减少更为明显。但是氩（Ar）杂质的注入导致D保留的增加。
