Abstract: The responses of shaft bow and their relationships with unbalanceresponses and mechanical or electronic run out are analyzed based on the theory of rotor dynamics.The responses of shaft bow are separated from the unbalance responses successfully 文摘:依据转子动力学理论分析了柔性转子弯曲响应的特征,在此基础上讨论了它与不平衡响应及机械与电气跳动量之间的关系,并利用转子在不同起车情况下的振动信息,有效地分离了弯曲响应和不平衡响应,求解出弯曲量与不平衡量的比值.提出了转子在恒定转速下,基于二维全息谱技术的热弯曲故障识别方法.研究结果表明,当弯曲量相位稳定而其幅值变化时,转子响应的二维全息谱初相点的切线是相互平行的,由此可以有效地实现转子热弯曲故障的识别与诊断.
Abstract: The restoration of the riparian vegetation disturbed by human activities is one of the hotspots of watershed ecology.Through interpreting the images of Remote Sensing in 1985 and 1999,the basic information of forest resources of Lushuihe Forest 文摘:本文对两期遥感图像进行解译,并在GIS支持下提取露水河林业局主要河流两岸各缓冲区森林资源信息,经分析得到各类地物在1985年及1999年的变化趋势.结果表明:在河流沿岸对森林的采伐强度1999年较1985年明显减小,整体生态环境较1985年有所改善.在缓冲区1,2,3除中龄针叶林大幅度增加外,其它地物类型面积均减少,由此可以看出,在这三个缓冲区内针叶林得到了较好的恢复.在缓冲区4内,中龄针叶林、成熟针叶林、成熟阔叶林形成一个林龄梯队,有利于森林生态系统的稳定与功能的发挥,十五年间缓冲区4受到的干扰相
