离子取代 meaning in Chinese

ion substitution
ionic replacement

Artificially softened water is exceedingly corrosive because the process substitutes sodium ions for magnesium and calcium ions
由于人工软化水采用钠离子取代镁离子和钙离子，因此具有极强的腐蚀作用。
It is reported that an increase in the zr content induces a reduction in the average grain size , decreases the dielectric constant , and maintains a leakage current low and stable . this is possible because the zr4 + ion has lager ionic size than ti4 +
Zr4 +离子取代ti4 +离子之后将会抑制ti4 +离子与ti3 +离子的电子跃迁,从而减小了薄膜的漏电流,同时还有助于减小平均晶界体积,降低介电常数。
The investigation of structure by x - ray diffraction shows that crystal parameters changes clearly when percenting ca and la into pbtio _ 3 , it was caused by the ca ion and la ion replaced the pb ion of a position in perovskite compound , that bring lattice mismatch and asymmetrical replace
在pbtio _ 3中掺入la和ca可以有效改变薄膜的晶格常数,这是因为在abo _ 3型化合物中,钙离子、镧离子取代了a位的铅离子,造成晶格失配和不对称取代。
