In the second part , some concepts and theoretics that are related to the antennas in the dissertation are introduced , as well as some review about the research background of reconfigurable fractal antennas 第二部分介绍了论文中所要涉及到的一些基本概念和理论,以及可重构分形天线的研究概况。
Conductivity reconstruction , one kind of electromagnetic measurement , reconstructs conductive property distribution of the biological tissue exposed to electromagnetic fields by measuring the fields around it . this thesis presents the application of improved genetic algorithm to reconstruct the conductivity distribution of stratified biological tissue by measuring the change of impedance in the coil 本文主要研究在载流线圈作用下,通过测量生物组织产生的二次场对线圈阻抗的改变,应用改进的遗传算法重构分层生物组织各层电导率和厚度的方法。
On the basis of the study on ore deposit geology , the paper discussed thedistribution of temperature field of ore body through mineral inclusion thermometry . combining with mineralizing elements distribution condition and the zoning feature of orefabrics , flowing direction of ore - forming fluid was also inferred in the paper 在研究矿床地质的基础上,使用矿物包裹体测温方法,研究矿体温度场的分布,配合矿化元素的分布状态和矿石组构分带特征,推断成矿流体的喷口位置和运移方向。
