摘　　要：以精馏和光解纯化工艺获得的高纯偏二甲肼为原料,制备了渗透率范围为0.5～30μg/min的偏二甲肼渗透管标准物质。经过均匀性、稳定性检验,结果表明:该标准物质均匀性、稳定性良好,为航天作业环境中各类快速检测仪的监控准确性提供了判定依据。The UDMH permeation tube were prepared with high purity UDMH as the raw material. The high purity UDMH was obtained by rectification and photocatalytic degradation, and the permeation rate scope was 0.5 - 30μg/min. The homogeneity and stability examination for 13 months showed that they were well. The permeation tube ean be used to judge monitoring accuracy of rapid detector.
