If analytical equipment is available, purge system until oxygen content of residual gas is either less than or meets the process specification impurity level.
如果有分析仪器的话，一直净化设备，直到残留气体的氧含量或者低于或者满足工艺规范的纯度级别。
The residual liquid processed by use of above method is up to colorless, smell less, no-impurity and anhydrous.
经过上述方法处理后的残液液体，达到无色、无味、无杂质、无水份。
The results show that the residual resistance ration relates not only to the aging temperature and the impurity concentration of the metal, but also to the aging time.
结果表明：金属铍的剩余电阻比不仅与时效温度和金属内杂质的浓度有关，而且受时效时间的影响；
