VERY little is known about the roles of microorganisms in the metallogeny of weathering crust REE deposits, although there has been much literature on REE behavior in weathering conditions. The present note deals with the microorganisms in 4 weathering profiles of an REE deposit and their roles in migration and accumulation of REE in weathering conditions. 1 Cultivation and identification of microorganisms Under strict sterilization, samples were collected from various parts of 4 weathering profiles of granites in a weathering crust REE deposit in South China. The samples were then cultivated for microorganisms with ordinary agars as culture media and then the cultivated microorganisms were dyed and identifiedunder a microscope. The sampled positions and cultivated numbers of microbial colonies are shown

关键词： microbial metallogeny weathering crust REE deposit South China.

基于声传感器阵列的变电站设备异常声源定位技术的性能不仅与处理算法有关,还取决于传感器的阵列模型,用增加传感器数目的方法提高估计性能的同时往往会导致成本的增加。为此提出了一种基于均匀平面阵的非冗余四阶累积量阵列虚拟扩展方法,该方法可以在不改变硬件设计的情况下提高阵列的性能。与低阶累积量相比,高阶累积量通过阵列的虚拟扩展增加了传感器数量,提高了定位估计性能和可分辨信源数目。此外,由于高阶累积量只包含非高斯分量的信息,因此扩展后的阵列具有更好的抗高斯噪声性能。为此还通过对累积量矩阵的去冗余降维处理,降低算法复杂度,提升定位方法的实时性能。仿真和现场测试结果表明,该方法可以实现比真实传感器阵元数目多的声源信号的定位估计,在低信噪比时定位精度得到明显提升,提高了定位方法的分辨率,且可有效减少算法的运算量。

现有的基于UHF的局部放电定位技术主要是基于时延来进行定位,为获得精确的时延需要非常高的采样率,由此带来了昂贵的硬件开销,极大地限制了其推广应用。为此提出了基于接收信号强度（RSSI）指纹的局部放电定位方法,该方法具有RSSI技术的低硬件成本及易实现性的特点,又具有指纹定位法对复杂空间环境很好的适应性。在离线阶段建立RSSI指纹图库包括测量方案、数据处理方法等,在线阶段应用综合粒子群算法和BP神经网络的PSO-BP定位算法对局部放电进行精确定位。在现场测试中使用模拟的局部放电信号对该定位方法进行了测试。试验结果表明,其平均定位误差为0.484 m,88%的定位误差〈1 m,定位方差也较小,从而验证了该定位方法的精确性和稳定性。
