摘　　要：在4—300K 的温度区间内,测量了金属玻璃 Zr_(100-x)Co_x(x=22,28,33.2)和Zr_(66.7)M_(33.3)(M=Fe,Ni,Cu)的电阻温度关系.实验指出,这两组典型的 Zr 基金属玻璃的电子输运性质,有着共同的规律性.分析表明,在10K<T<80K 时,这种规律可以用弱局域化理论来解释;而当 T>80K 时,这种规律与现有的理论有较大的偏离,对这种偏离出现的可能起因作了讨论.The temperature dependence of resistivity has been measured for metallic glasses Zr100-xCox(x=22,28,33.2) and Zr66.7M33.3 (M=Fe,Ni,Cu) in the range from 4K to 300K.The results show that there is a common regularity in these typical Zr-based glassy metals,In 10K <T<80K,the regularity can be explained by a weak localization theory.When T>80K,the regularity has larger departure from the present theories.The cause that induces this departure is simply discussed.
