Water has higher melting point , boiling point , heat of vaporization , heat of fusion and surface tension than comparable hydrides such as hydrogen suiphide or ammonia or most liquids 与氢硫化物、氨水或其他大多数的液体相比，水具有较高的熔点、沸点、蒸发比热、熔解热和表面张力。
By experiments the conclusions were got that the actived carbon electrode could provide better capacitive character in 7mol / l potassium hydroxide solution after activation in ammonia 通过大量的实验发现氨水活化处理后的活性炭在浓度为7mol l的氢氧化钾溶液中具有良好的电容性能。
Dl - aspartic acid has been synthesized from maleic anhydride and ammonia , the yield of dl - aspartic acid was above 70 % which is much higher than those reported in the literature 摘要以顺丁烯二酸酐与氨水为原料合成dl -天冬氨酸，使其得率由现有的63 %提高到70 %以上，并对其反应机理进行了研究。
In addition , police also discovered various quantities of other chemicals , mainly hydrochloric acid , ammonic and acetone , which are suspected to have been used for the conversion of the solution containing cocaine into powder - form cocaine 此外，警方亦检获多种化学物品，包括盐酸、氨水及丙酮。警方怀疑该等化学物品是用以将混有可卡因的液体提?成粉状可卡因。
