摘要：

本文给出了在10^{13}-10 ^{14} eV能量范围内一年测量各向异性随能量变化的初步结果。比较了两种数据分析方法的结果：一种是采用气象改正的标准方法，另一种是所谓的“东减西”方法。本文报道了三个中位能量E = 25 TeV、E = 75 TeV和E = 120 TeV的各向异性的振幅和相位。阐述了各向异性对能量的幅相依赖性的简要考虑。

英文摘要：

Preliminary results of one year anisotropy measurement in the energy range 10^{13} -10^{14} eV as a function of energy are presented. The results are compared for two methods of data analysis: the standard one with meteo correction approach in use and another one so-called "East minus West" method. Amplitudes and phases of anisotropy for three median energies E = 25 TeV, E = 75 TeV and E = 120 TeV are reported. Brief consideration of amplitude-phase dependence of anisotropy on energy is expounded.
