rise-decay time meaning in English

上升衰减时间

Were used for this study . durations of tone and weak white noise bursts used as sound stimuli were both 40 ms ( 2 - ms rise - decay times ) , and delivered synchronally at 2 per second in free field . 177 neurons were obtained in this experiment , and frequency tuning curves ( ftcs ) of 76 ic neurons were measured in our study
本实验共用12只健康、听力正常的成年小鼠，雌雄不拘，共获得177个神经元，测量了76个神经元的频率调谐曲线( frequencytuningcurve ， ftc ) ，发现弱噪声对神经元ftc的影响有三种类型：锐化、拓宽和基本不受影响。
