   通過對一系列不同晶粒尺寸cosb _ 3化合物的熱導(dǎo)率、電導(dǎo)率和seebeck系數(shù)的測定，討論了晶粒尺寸大小對結(jié)構(gòu)納米化對熱導(dǎo)率、電導(dǎo)率和seebeck系數(shù)的影響，結(jié)果表明：隨著cosb _ 3化合物晶粒尺寸的減小，晶格熱導(dǎo)率_ l顯著降低，從而導(dǎo)致cosb _ 3化合物的熱導(dǎo)率的降低；電導(dǎo)率也有一定的降低；以及seebeck系數(shù)顯著增加。
2. The filled skutterudite compounds attract aboard attention owing to their high mobilities and relatively large seebeck coefficients in the middle temperature range of 600 - 800k . but their thermal conductivities are very high , so the problem how to decrease their lattice thermal conductivities and improve their zt values becomes a research hotspot
