The existence of various lacunas in bolt bonding system will cause the acoustic wave energy attenuation, phase aberration and frequency dispersion.
由于锚固体系中有不同大小和程度的缺陷，声波在传播过程中将产生能量衰减、相位突变及频散现象。
The results of simulation show that dispersion seriously reduces the peak power and sample energy on the FFH OCDMA system. Hence, bit error rate(BER) of system is increased by dispersion.
结果表明，在FFH- OCDMA系统中，光纤色散导致解码自相关光脉冲峰值功率和光脉冲取样能量的降低，进而导致系统误码率（BER ）的增加。
