由于地层吸收衰减及球面扩散,使得深层地震反射波的振幅衰减严重,导致地震仪记录信号的有效动态范围远小于120dB,满足不了高分辨率地震勘探对记录信号动态范围的要求。从视等厚层状吸收介质模型入手,理论计算了地震反射波的振幅谱。其特征分析表明:反射波振幅随深度的增加按指数规律衰减,但衰减主要发生在1.5s前的中浅层。设计了智能程控型前置放大器,它的增益随深度增加自动增大,其值依次为0dB、18dB、24dB、30dB、36dB和42dB,使深浅层地震反射波的振幅在记录前均得到适当补偿,确保了地震仪记录信号的有效动态范围接近120dB,这对高分辨率地震勘探理论和开发新一代地震仪具有重要意义。

针对插电式燃料电池汽车(PFCHV)能量管理优化控制问题,为在保证经济性的前提下兼顾燃料电池的使用寿命,提出了考虑燃料电池寿命衰退的自适应等效氢耗最小策略。将燃料电池在启停、大功率波动与重载等状态下的寿命衰减量化为使用成本,并将其与燃料电池氢耗、动力电池电耗共同组成等效氢耗成本。建立了融合短时车速预测与电池SOC反馈的等效因子自适应调整方案,同时依据动力电池SOC的状态变化而不断调整等效因子的调节周期,实现等效因子的高效调节,以保证该策略能够更好地适应不同的行驶工况。在NEDC、CLTC标准工况下,所建立的控制策略与ECMS策略相比氢耗量下降9.5%和17.66%,燃料电池寿命衰退改善37.3%和47.1%。燃料电池的不良运转工况有所减少,同时动力电池SOC维持能力有所提升,提高了整车的经济性与燃料电池系统的耐久性。
