1. The experiments show that with large pulse width and high repetition rate of pump pulse, the dependent jitter scope of output laser pulse with pump pulse is increased. 结果表明在抽运时抽运脉宽和重复率较大的情况下,输出激光脉冲相对于抽运脉冲抖动范围明显加大。
2. A rectangular pulse and a rectangular pulse with first pulse differentiated and the spectrum is the spectrums of pulse multiplied by the angular frequency. 一方波及一方波,其前一脉波之微分。验证其频谱为原本频谱乘以频域之角频率,但微分定理对于不连续脉波只有低频部份有较精准之近似。
3. Turn on oximeter by activating power. Observe pulse waveform/intensity display and audible beep. Compare oximeter pulse rate with client's radial pulse. 打开电源,接通血氧计。观察脉搏波形/强度和嘟嘟声。对比血氧计脉率与病人桡动脉搏动。
4. The design method for hybrid waveforms utilizing ran-dom poly-cell code pulse position modulation (PPM) and pulse-to-pulse binary sequences phase modulation (PM) is introduced in this paper. 该文提出了一种利用随机多元码脉位调制(PPM)和脉间伪随机或随机二元序列相位调制(PM)相结合的混合波形设计方法。
5. In this paper, the distorted pulse shape is derived in the chirp pulse transmission through dispersive optical fiber , and the method is given for the chirp pulse not to be widened. 本文导出了啁啾激光脉冲经色散光纤传输后的畸变波形,以此为基础讨论了避免啁啾光脉冲被光纤展宽的各种方法。
