摘　　要：用快、慢光电倍增管分别构成两种探测装置,记录了广延空气簇射(EAS)切伦科夫()光的脉冲形状和光强.测量了海平面EAS(能量E_0>5×10^(14)eV)光脉冲的半高全宽(FWHM)分布和光子密度谱.两种光强探测结果的比较表明:由GDB100慢光电倍增管和峰值ADC组成的光强测量系统,对于测定EAS光的光强是一种简单和经济的好方法.The pulse shape and the intensity of Cerenkov light from extensive air shower have been recorded by using two different types of photomultipliers (fast and slow). The distribution of the FWHM of Cerenkov light pulse and the spectrum of Cerenkov photo density have been measured for E>5×10^(14)eV, at sea level. Comparing the two intensity results from two types of tubes indicate that the system which consists of the slow tubes and the peak ADC is not only simple but also cheap for the Cerenkov light intensity measurement.
