摘 要：节点定位是无线传感器网络中的关键技术之一。基于rssi的定位技术是现阶段研究的热点，为解决rssi测量方法定位误差较大的问题，提出一种将rssi测量方法与三角形质心算法相结合的新型定位算法，该算法用三角形质心算法减小rssi的测量误差。仿真表明该算法比基于rssi的三边测量法定位算法的定位精度有较大提高。

From the earliest known for the IFP-100 series, iRiver and proves that his great strength, from out of the sound quality of MP3 no good argument, the iron triangle design enjoys popular support and become classics; after the IFP-300, IFP - 700, IFP-800 continuation of the iron triangle of brilliant, but also the achievement of high-quality high-end Philips chip status, although later experienced core for the short-term decadence, T series or have been successful, also shows that the style and sound Aere The shift, and the recently introduced T50, T60 also for the excellent cost-effective, access to a lot of warm FANS sought after, a gorgeous high-end color of CLIX, the attractive, compact S10, S7, the beautiful people爱不释手Guaiqiao Mplayer and so on. Aere dynasty and show that the overall boom!

从最早的成名之作IFP-100系列开始，艾利和就证明了自己强大的实力，从此摆脱了MP3没有好音质的说法，铁三角的设计深入人心，成为经典；后的IFP-300，IFP-700，IFP-800延续了铁三角的辉煌，也成就了飞利浦芯片高端高素质的地位；虽然后来经历了换芯的短暂颓废，T系列还是获得了成功，也标志着艾利和声音风格的转向，而最近推出的T50，T60也以出色的性价比，获得了众多FANS的热烈追捧，高端华丽出彩的CLIX，小巧可爱的S10，S7，让人爱不释手乖巧漂亮的Mplayer等等，都表明艾利和王朝的全面繁盛！

The advantages of this new method are:(1) The field conductivity distribution function is fitter the actual condition than tradition methods:(2) On the condition of triangle elements cut of field, making the calculation speed increase in large degree than tradition methods.

与单元电导率重建算法相比，节点电导率重建算法的优点有：(1)使场域电导率分布函数更符合实际情况，克服了传统算法中对电导率作离散化处理的缺陷；(2)当场域采用三角形单元剖分方式时，在场域的剖分密度保持不变的情况下，可以大大提高重建计算的速度；(3)在场域采用三角形单元剖分方式时，场域的剖分密度可以比以前加大一倍，在不降低重建计算速度的前提下，可以改善重建计算的精度；(4)由于重建的是所有节点的电导率，避免了先前单元电导率重建图像中"阶梯"状边缘和"锯齿"状边缘的出现，明显地改善了图像的视觉效果。

Our study contained three sub experiments: First, we looked into the music perception neural mode under the u...更多n-attention condition, then pre-attention condition, and attention condition at last. It suggested that:1. Similar to the past studies, ERAN was also acquired when irregular chords was played to both music experts and ordinary persons, with the former swings larger than the latter ones, and the former delitescence earlier than the latter ones.2. N5 was also acquired in the same condition, and it reflected the conformity process of music perception. The swings of experts' N5 were lager than the ordinary ones, and delitescence earlier.
