亚磷酸铅 meaning in Chinese
lead phosphite dibasic
Examples
- Preparation of ultra - fine dibasic lead phosphite powder by precipitation method
化学沉淀法制备超细二盐基亚磷酸铅粉体 - Lead hydrogen phosphite superfine powder , lead oxide phosphite hydrate superfine powder and tribasic lead sulfate superfine powder were prepared by micro - liquid - phase synthesis method ( mlps method ) in this paper . at room temperature , acetic acid worked as catalyst , lead oxide and phosphite or sulfate were blended thoroughly , then were ground for tens minutes
本文采用微液相合成法制备了亚磷酸铅、二盐基亚磷酸铅和三盐基硫酸铅超细粉末，以氧化铅和亚磷酸或硫酸为原料，以醋酸为催化剂，在室温下充分混合、研磨几十分钟，干燥后即可得到产物。 - Tem was used to consecutively investigate the size and appearance of dibasic lead phosphite in the reaction process . it found that nanocrystal grain of lead oxide phosphite hydrate had favorite direction in the mlps method , many nanocrystal grain in near area would aggregate and assembled as nanowire , the diameter of the nanowire was about a crystal grain size and the length of nanowire could reach hundreds of nanometers , then they would gather to needle or bar like particles
利用tem对二盐基亚磷酸铅在反应过程中粒子的大小、形貌进行跟踪观察，并记录下三个时间下的微粒照片，发现用微液相合成法制备的二盐基亚磷酸铅晶粒在生长团聚时存在取向规律，同一区域的晶粒会长成一条纳米线，直径有一个晶粒的大小，长度可以达到几百nm 。
