1) carbonic acid
碳酸
1.
Experimental study on effect of acetic acid and carbonic acid on clay’s geotechnical behaviors;
乙酸和碳酸对粘土土工性状影响的试验
2.
The source,existing form and equilibrium of carbonic acid in natural water are presented in this article,which points out that alkalinity is determined by double indicator that indicates purply at the first terminal point,while at the second terminal point should use methyl red-bromocresol green mixed indicator.
介绍了天然水体中碳酸的来源、存在形式及平衡关系;指出用“双指示剂”法测定水中碱度的第一终点应显粉紫色,第二终点宜采用甲基红-溴甲酚绿混合指示剂;测定游离二氧化碳要用双样测定并严格控制滴定终点;各种碳酸的含量可与pH值、硬度的测定结果进行校核。
2) carbonate carbon
碳酸盐碳
1.
In this study, carbonate carbon is used as an indicator for sand storm and dust storm source identification for the first time in China, taking the characteristic of China aerosol into account On the basis of carbonate carbon measurement of such samples as aerosols, Asian dust, soil and sands in source area, some conclusion is drawn and compared with other research methods.
根据中国大气颗粒物特点 ,在国内沙尘暴研究中首次尝试利用碳酸盐碳进行沙尘暴来源地识别。
3) Carbonate (anhydride carbonate)
碳酸盐(无水碳酸)
4) durcal
碳酸及碳酸钙
5) carbonate
[英]['kɑ:bəneit] [美]['kɑrbə,net]
碳酸盐，碳酸酯
6) Carbonic Acid,Carbonates and Carbides
碳酸，碳酸盐，碳化物
补充资料：碳酸
化学式H2CO3。为二氧化碳溶于水生成的二元弱酸。在常温、常压下,二氧化碳饱和溶液的浓度约为0.033Μ，pH为4。二氧化碳在溶液中大部分以微弱结合的水合物形式存在，只有一小部分形成H2CO3。在常温时CO2:H2CO3为600:1。碳酸的热稳定性很差,在加热时全部分解并放出二氧化碳。碳酸在碱的作用下，可分别生成酸式碳酸盐和碳酸盐。
