5) migration
[英][maɪ'ɡreɪʃn] [美][maɪ'greʃən]
迁移规律
1.
Study on the migration of lead and arsenic during underground coal gasification;
褐煤地下气化过程中铅和砷的迁移规律的研究
2.
Since the migration of charged ions has the direct influence on the efficiency of separation and determination, therefore, the research on the migration of charged ions in the electrophoresis can help to optimize the electrophoresis conditions to obtain good results.
但其应用范围主要在于微量荷电粒子的分析与鉴定,而对于连续制备过程应用较少,因为在此条件时,电场中离子的迁移规律直接影响分离、鉴定的结果,因此,研究电泳过程中荷电粒子的迁移规律对优化电泳条件具有重要意义。
补充资料:迁移
分子式:
CAS号:
性质:又称渗移,泳移。在场的作用下,物质的分子、离子或其他粒子等沿一定方向的运动。场可以是电场、磁场、重力场或离心力场、浓度场等。例如在电场下的迁移是电泳;在浓度场下的迁移是分子扩散;在重力场下的迁移是沉降;在温度场下的迁移是热扩散。
