移动度 meaning in Chinese

degree of excursion

As a type of potentially good thermoelectric materials , cosb3 compounds with the skutterudite crystal structure mx3 have attracted attention widely , because of their high carrier mobility , large electrical conductivities , and large seebeck coefficients . however , the thermal conductivity of skutterudite is too large , so , zt is low . therefore reducing the thermal conductivity of cosb3 has becomed a main research way at present
Cosb _ 3方钴矿化合物作为一种具有潜在高热电性能指数的新型中温热电材料具有大的载流子移动度、高的电导率和较大的seebeck系数，但由于热导率较大，因此要提高cosb _ 3方钴矿化合物的热电性能，降低其热导率是当前研究的热点之一。
