The results show that the fluidization characteristics of scrap printed circuit board particles depend on the average size and type of particles. The scrap printed circuit boards particles, belonging to Geldart A group with strong viscous force, whose fluidization was similar to fluidization of Geldart C, was difficult to fluidize. Whereas, the scrap printed circuit board particles belonging to Geldart B can be fluidized smoothly.

实验结果表明，电路板塑料颗粒为Geldart A类颗粒时，粘性力大，塌落特性明显，流化性能较差，具有拟C类颗粒的流化特性；电路板塑料颗粒为B类颗粒时，塌落特征不明显，并且随着粒径的增大，最小流化速度也增大。

This article expatiated on the structure and principle of coreless transformer in printed circuit board, introduced and analysed the Hurly_duffy's method to calculate the self and mutual inductance of coreless transformer in printed circuit board in which I found the fault, re-modified the current unit model, deduced a new formula used commonly, and offered testing process and circuit as well as mended the structure of coreless transformer which made the analysis easy.

本文阐述了无芯印制板变压器的基本结构和原理，介绍和分析了Hurly-duffy 的无芯印制板变压器自感和互感的计算方法，指出了它的不足，在纽曼公式的基础上，重新修正了电流元模型，将线圈看作是粗线圈，推导出普遍适用的计算公式，并给出了测试方法和测试电路。
