【摘要】

：

提出了一种基于时频分辨的精细描述方法,有效地对核脉冲信号的快速及奇异变化进行表达.对核脉冲信号进行多层时频分解,自适应选择香农熵意义下的最优子频带空间,并提取各空间重要系数作为描述信号的特征参数.结果表明,用来描述信号的特征参数仅占原始数据量的6％便可将脉冲幅值及其时间常数误差控制在0.4％以内,波形及其奇异点重要信息保持完好,对于后续核脉冲成形及参数获取等数字处理过程的研究具有重要意义.

半航空瞬变电磁测量系统发射系统研究

在半航空瞬变电磁测量系统中,瞬变电磁发射机场源系统在测量中占有重要地位,它产生一次电磁场激发地下地质体,当瞬变电磁发射机场源关闭时产生,激发地下地质体将产生二次场.通过测量二次场的变化,进行目标体的探测.本文根据半航空瞬变电磁测量系统的要求,设计了30kW的半航空瞬变电磁测量系统发射机系统,其发射电压可达600V,最大电流为100A,发射频率为1.25～200Hz,能发射多种波形,关断时间小于50

横向交变载荷作用下双螺栓连接结构的松动试验研究

在自主设计的试验设备上对双螺栓连接结构进行横向交变载荷下的松动试验,研究拧紧方式、载荷水平和材料配副等因素对松动的影响.结果表明:拧紧方式和载荷幅值对松动影响明显.相同实验参数下,双螺栓结构中同一螺栓的预紧力损失分散性大,不同螺栓的松动程度差异更大,一般靠近加载端的螺栓松动程度大.采用铝/钢配副比钢/钢配副预紧力大从而防松效果明显.
