遗憾的是，它也和许多已被人类淘汰的其它熏蒸剂一样，由于它属于消耗大气臭氧层的物质[1]，为了保护人类子孙万代良好的生活环境，已经在国际上取得共识，把它列为逐步淘汰的物质[2]，而且已于1979年开始采取了具体的法规性行动[3][4]。

The concentrations of CO2, CF4, thionyl sulfide (SOF2), sulfuryl fluoride (SO2F2), disulfuryl decafluoride (S2OF10), sulfur dioxide (SO2) and sulfureted hydrogen (H2S) were in partial normal distribution. The concentrations of CO2, CF4, SOF2, SO2F2, S2OF10 were all below 0.1%; the concentrations of SO2 were below 3μL/L; the concentrations of H2S were below 1μL/L. The SF6 byproducts concentrations in 500kV GIS were lower than those in 220kV GIS. The SF6 byproducts concentrations were lower in GIS that have been operating longer. The SF6 byproducts concentrations were significantly different in equipment from different manufacturers.

结果显 示：SF6 GIS 中CO2、CF4、氟化亚硫酰（SOF2）、氟化硫酰（SO2F2）、十氟化二硫酰（S2OF10）、二氧化硫（SO2）和硫化氢（H2S）都成偏正态分布，其中，CO2、CF4、SOF2、 SO2F2、S2OF10 的含量均小于0.1％，SO2 的含量均低于3μL/L，H2S 的含量均低于1μL/L.500kV GIS 设备中SF6 分解产物含量低于220kV GIS 设备；运行时间越长，设备中SF6 分解产物的含量越高；不同设备厂商的GIS 中 SF6 分解产物含量有显著性区别。

The concentrations of CO2, CF4, thionyl sulfide (SOF2), sulfuryl fluoride (SO2F2), disulfuryl decafluoride (S2OF10), sulfur dioxide (SO2) and sulfureted hydrogen (H2S) were in partial normal distribution.

本文总结了广东省74 个220kV 和500kV 全封闭组合电器变电站共3770 个气室中SF6 分解产物的含量，为SF6 GIS 潜伏性故障及其故障类型判断累积经验。

The radiation synovectomy using188Re-Sulfide was a kind of effective and safe method of treating osteoarthritis of the knee.

188Re-硫化铼放射性滑膜切除术是治疗膝关节骨关节炎的一种有效和安全的方法。

The sediment of sulfide can be separated from the solution by filtration and syphon. After the sediment is dissolved by diluted nitric acid, Ni 2+ and Co 2+ in solution can be determined by the flame atomic absorption spectrometry method.

将沉淀过滤，或者加入明矾以加速硫化物的沉降、凝结，再用虹吸法吸去上层清液的方法将沉淀分离，用热稀硝酸将沉淀溶解后直接用火焰原子吸收法测定镍、钴的含量。
