Normal-state properties of some epitaxial YBa₂Cu₃O_7-δ thin films which were derived from the metal-organic deposition route were studied through the context of Aslamazov and Larkin theory of fluctuation conductivity. Six samples with various superconducting properties were selected for this purpose. Resistivity vs. temperature analysis showed that the general normal-state behavior of the samples can be described by 3D, 2D, and 1D Aslamazov and Larkin model of fluctuation conductivity. Samples with the higher superconducting transition temperatures showed the higher Josephson interlayer coupling. Moreover, a linear behavior has been found between Josephson interlayer coupling constant and critical current density. In addition, fitting excess conductivity with Lawrence-Doniach (LD) and Maki-Thompson (MT) models revealed that the LD term dominates in 3D region near the superconducting transition. However, the MT term gains an important role in 2D region far away superconducting transition.

一些外延的YBa的正常状态的属性₂的Cu ₃ ö _7-δ通过Aslamazov和Larkin波动电导率理论研究了由金属-有机沉积途径衍生的薄膜。为此选择了六个具有各种超导特性的样品。电阻率与温度的关系分析表明，样品的一般正常状态行为可以通过3D，2D和1D Aslamazov和Larkin波动电导率模型来描述。具有较高超导转变温度的样品显示出较高的约瑟夫森层间耦合。此外，已发现约瑟夫逊层间耦合常数与临界电流密度之间存在线性关系。另外，用Lawrence-Doniach（LD）和Maki-Thompson（MT）模型拟合过量电导率表明，LD项在超导转变附近的3D区域占主导地位。
