场强

The proposed algorithm improves localized nodes ratio by multihop centroid calculating，and improves localization accuracy by decentralizing process and signal strength-weighting process.

该算法对单跳质心算法进行多跳扩展以改善定位比率，并加入场强加权过程和去中心化过程以提高定位精。

By the method of electril charge projection the expression of charge density and field intensity on midperpendicular plane on a conductive plate are given.

利用电荷法,给出导体板上电荷密示式和中垂面上场强分布。

At highest field strengths, the core of the clot may have low signal on T2-weighted images, due to the presence of intracellular methemoglobin or of deoxyhemoglobin.

高场强时，血块中心在T2加权像上是低信号，这是由于细胞内高铁血红蛋白或还原型血红蛋白存在产生。
