系统研究了填充原子的种类、填充方式以及置换原子的种类对晶格热导率及热电性能的影响。
The effects of the kinds of filling and replacement atoms and the form of filling on the lattice thermal conductivity and thermo-electric property were discussed in this paper.
例如有机锡的稳定剂可以和羧甲基纤维素分子的不稳定氯原子配位结合，有机锡和不稳定的氯原子发生置换反应。
For example, the stabilizer of organotin compounds can be combined with the unstable chlorine atom of the carboxymethyl cellulose molecule, and the organotin and unstable chlorine atoms are replaced.
方法：用原子吸收分光光度法测定血液滤过置换液中总钠含量，并根据《测量不确定度评定与表示》（JJF1059-1999）中有关规定评估其不确定度。
Methods:To determinate the total sodium in hemofiltration replacement fluid by atomic absorption spectrophotometry and appraise the uncertainty according to JJF1059-1999.
这就使得用重金属原子作同晶置换法遇到了麻烦。
This can make heavy atom derivatization in the presence of reducing agents, difficult and frustrating.
元素的特征价数是以该元素一个原子可结合的氢原子数或可从一化合物中置换出的氢原子数来表示。
Hydrogen (h) always has valence 1, so other elements' valences equal the number of hydrogen atoms they combine with.
