【摘要】 利用单泡声致发光光脉冲间期短以及与声场精确同步的特点,首次把高时辨的光子计数器用于单泡声致发光光谱的测量,极大程度地提高了信噪比,在较高的灵敏度下亦可达到较高的分辨率.利用该方法得到了稳态单泡声致发光的光谱曲线,并且对原始光谱曲线进行了校准.更多还原

【Abstract】 Due to the picosecond flashes and the weak intensity of light it is hard to measure the spectrum of single bubble sonoluminescence(SBSL).In terms of the characters of the short flashes of light and the clocklike regularity,the time-discrimination photon counting was utilized to measure the spectrum of SBSL for the first time. The signal-to-noise ratio is improved and the high resolution can be attained.The spectra of SBSL were obtained after the calibration.更多还原
