摘　　要：文章采用熔融电解还原法制备纯的蓝青铜单晶Rb0.3MoO3,测量了该样品的低场电阻—温度关系和非线性电输运性质。在100K以下,纯样品的ET1随温度的升高而增大。研究了蓝青铜Rb0.3MoO3在77.1K下电荷密度波的横向电流调制效应随着横向调制电流由零逐渐变大,样品的ET1呈减小变化,在定性上符合Radzihovsky等人的理论预期。In the paper,the single crystals of molybdenum blue bronze and rubidium blue bronze (Rb__(0.3)MoO_3) are successfully prepared by the electrolytic reduction method and with Rb_2CO_3and MoO_3. The resistance-temperature correlation and nonlinear transport of Rb__(0.3)MoO_3in a low electric field are investigated. The result shows that E__(T1)of the pure bronzes increases with the increase of temperature below 100　K. Furthermore, the transverse current-effect of rubidium blue bronze (Rb__(0.3)MoO_3)at the temperature of 77.1　K is researched. The result shows that E__(T1)of the pure bronzes decreases with the increase of the transverse current.
