wave packet造句
例句与造句
- The reasons focusing only on ray travel times are " noise tolerance could be enhanced and the sensitivity to the environment model mismatch may be reduced by neglecting amplitude information ; phase ambiguity is eliminated by employing the group delay of arriving wave packets ; travel times are pseudo - linear functions of sound speed profiles of the medium , and the perturbation of ray travel time is much smaller than sound pressure ' s
之所以选择声传播时间的原因是：噪声容限可以得到提高，并且传播时间的计算可以不考虑声压的信息，从而降低了对环境模型失配的敏感性；相位的起伏也可通过到达包络的群延时来消除；传播时间是介质声速分布的伪线性函数并且传播时间的起伏远小于声压的起伏。 - When the pulse width of input gaussian wave packet was reduced and the length of forbidden region retained , the result displayed the output signal distorted seriously and its spectrum changed very hard . a frequency above the cut - off frequency became the main frequency and the group velocity was below than c
在保持截止区长度不变，而减小输入高斯波包的脉冲宽度时，模拟显示输出波形严重失真，而且，频谱也发生很大的变化，主频已变为一高于截止频率的频率，群速度小于光速c 。 - The followings were discovered in the simulations of undersized waveguide : when the pulse width of input signal , a gaussian packet , is rather wide , the output signal distorted little . a superluminal group velocity 3 . 21c was revealed when the wave packet crossing 50mm forbidden region
对凹陷波导（ undersizedwaveguide ）的模拟发现：输入脉冲宽度较大的高斯波包，模拟结果显示输出波形失真较小，经过计算得到电磁波包穿过长50mm的截止区时，电场的幅度衰减了- 41 . 5db ，群速度为3 . 21c 。 - It's difficult to find wave packet in a sentence. 用wave packet造句挺难的
