An investigation on the corrosion behavior of 55 al - zn - 1 . 6 si alloy coat in ammonia water 合金镀层在氨水中的腐蚀行为研究
Aqua ammonia applicator 氨水注施机
Imaging materials - ammonia - processed diazo photographic film - specifications for stability 成象材料.氨水处理重氮摄影胶片.稳定性的规范
Character : light pink poweders , dissolving in ammonium water slightly dissolving in water and acids 性状:浅红色粉末,溶于氨水,微溶于水和酸。
Serum leels of amylase , lipase , and electrolytes , and plasma leels of ammonia were normal 血清淀粉酶,脂肪酶和电解质水平无异常,血浆氨水平无异常。
Effects of initial ammonia concentration upon mass transfer rate have been investigated 实验分析中,讨论了初始氨水混合液浓度对氨蒸汽吸收率的影响。
Treatment of ammonia and phenol in residual - ammonia wastewater from coking mill by membrane absorption process 膜吸收法处理焦化厂剩余氨水中氨氮及苯酚
In a small bowl , soak the jewelry in a half - and - half solution of cold water and household ammonia for thirty minutes 取一小碗,将首饰浸入日用氨水与凉水1 : 1所配成的溶液。
First , it has been found that the less the initial ammonia concentration , the greater the mass transfer rate 首先可以看到氨水混合液的初始浓度越低,氨蒸汽的吸收量越大。
Production : monomer boron , danhuapeng , boron anhydride , without detectable ; hydrochloric acid , yean , ammonia water 生产:单体硼,氮化硼,硼酐,无水硼砂;盐酸,液氨,氨水。
