摘要
文中结合日常工作中对液体无水氨残留物含量测定分析的实际情况,对国家标准GB/T8570.4-2010使用中遇到的问题提出了改进建议,并推算出新的简化计算公式,既保证了测量精度又提高了测量效率,值得同行业参考和借鉴。
in this paper, combined with the actual situation of the determination and analysis of the residue content of liquid anhydrous ammonia in daily work, the national standard.The problems encountered in the use of GB/T 8570.4-2010 are proposed, and a new simplified calculation formula is derived. The easurement accuracy is guaranteed, and the measurement efficiency is improved. It is worth the same industry reference and use for reference.
