Using the propertyof Markov at the points of replacement period, a model of determining the optimal period is developed with objective of maximizing the mean time to first failure of system.
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.
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。
