dipole layer meaning in English
偶极层
偶极子层
Examples
- Firstly , sp supposed to be generated by point curl source which is the border of dipole layer rather than the line dipole layer in section view , then , curl source scanning function is given , and image is retrieved by probability tomography approach
首先把剖面上偶极层的线分布产生的场看作是偶极层的边缘旋度源的点分布产生的场；然后给出旋度源的扫描函数，用概率成像方法对旋度源进行成像。 - The current trends of this field is to acquire the current density of dipole distribution rather than a few dipoles . based upon that , a new model was proposed - dipole layer localization method ( dllm ) : spherical dipole layer was used as source model , on which dipoles were distributed by equilateral triangles ; three concentric inhomogeneous sphere was used as head model , which contains scalp , skull and cortex with different conductance . the dipole distribution and scalp potential tomography were obtained with singular value decomposition ( svd )
鉴于该领域的研究趋势已从求取少数偶极子过渡到偶极子分布密度的获得，本文提出了新的模型? ?偶极面定位方法( dipolelayerlocalizationmethod ， dllm ) ：以等边三角形均匀分布的偶极子构成的偶极面(球面)作为源模型；包括头皮、颅骨和皮层的三层同心介质球作为头颅模型，运用奇异值分解来求解逆问题，从而获得偶极子分布和头皮电位分布，实现三维成像。 - In the simulation study , the parameters of dipoles were given , it would be considered whether it could be recovered correctly by dllm based on scalp potential sampling with a set of electrode array . it was also examined that how electrode number influenced the recovered quality of dipole parameters . the simulation showed that the number , position and strength of dipole set were greatly close to the original condition ; the shallower the dipoles were , the higher the precision of source localization was ; the optimal depth of dipole layer was greatly close to the ideal position ; the accuracy of source localization was increasing when more electrodes were used
在仿真研究中，首先设定已知的偶极子数目及其所在的偶极面深度等参数，然后用一定数目的电极抽取正向计算获得的头皮电位，考察该模型在上述理想条件下，基于头皮电位是否能正确获取偶极子数目及其参数、以及电极数目对结果的影响。
