The optimal conditions for synthesis of alkali green 4 are reported, including the carbamide and zinc chloride as catalyst, chloranil and bichrome as oxidation agent in the acetic acid medium. 报道了合成碱性绿-4的最佳条件:在醋酸介质中,尿素、氯化锌为催化剂,四氯苯醌和重铬酸钾为氧化剂;
In the paper the fluctuation in temperature measuring by original bichrome thermometer is analysed and the improvement is introduced. 分析了在钢筋热处理线的温度测量中,常规红外双色测温仪测量值跳动较大的原因,并据此对双色测温仪进行了改进。
