例句与用法
- Mar 01 , the doc of the usa initiated antidumping investigation against sodium hexametaphosphate ( shmp ) from china
3月1日,美国商务部发布公告，对原产于中国的进口多聚磷酸钠（六偏磷酸钠）进行反倾销调查。 - Hi this thesis , the setting time of various retarders had been tested , in which three retarders with good retarding action , citric acid , sodium tripolyphosphate , bone glue are respectively chosen from three types of retarders , hydroxyl carboxylic acid type , phosphate type and protein type , and the strength and setting time of gypsum added with them are determined . effect of some factors , such as ph value , fineness of hemihydrate , type of gypsum on the retarding action of the retarders is also studied
本文对多种缓凝剂进行凝结时间测试，选择效果良好的羟基羧酸、无机盐和蛋白质类型的三种缓凝剂：柠檬酸、多聚磷酸钠和骨胶，测定它们对石膏凝结时间、强度等宏观性能的影响，并分别研究ph值、石膏细度和石膏种类等因素对它们的缓凝效果的影响。 - Through the analyzing the macro - structure to micro - structure , the author considers that retarding mechanism of citric acid is that citric acid and ca in the gypsum form the complexant ion , and hinder the crystallization center of dihydrate crystal bigger ; that of sodium tripolyphosphate is that it combined with ca , hinders the dissolve of hemihydrate . formation and growth of crystallization center ; that of bone glue is the glue - protection and chemical absorption action of active group , which also retards the formation and growth of crystallization center
通过宏观到微观的分析，笔者认为，柠檬酸的缓凝作用的原因主要在于柠檬酸与钙形成络合离子，影响了二水石膏晶体的晶核长大过程；多聚磷酸钠与钙形成某种复盐，对于石膏晶体的溶解、成核和长大过程均有强烈的阻碍影响；骨胶则在于胶体对半水石膏的包裹和活性基团的化学吸附，使二水石膏晶体的成核和长大困难。 - Amp and adp were not significantly changed throughout the experiments , pa tended to decreased with the increases of concentrations of pollutants , nitrite - na and sodium polyphosphate could decrease atp , while methyl parathion showed a disordered atp change . aec , atp / adp and total adenylate content solely could be poor health condition markers . pa and atp are proposed as direct health condition markers of an organism to environmental stress
整个实验中未发现腺苷一磷酸( amp )和腺苷二磷酸( adp )有显著变化，磷酸精氨酸随着化合物浓度升高呈下降趋势，亚硝酸钠和多聚磷酸钠能引起腺苷三磷酸( atp )下降，而甲基对硫磷中atp变化混乱。
