摘要本文应用因子分析模型L及其解，求出了经典因子分析模型中公因子载荷、公因子、特殊因子的精确解，解决了经典因子分析模型和理论存在的9个问题，进一步，指出了经典因子分析模型及其解根本的局限性问题：公因子解没有排除观测误差的干扰，不能达到降维的目的等。

For most extrusion grade Estane TPU products,the hopper should be sized so that all of the feed has been subjected to a minimum of two hours of dehumidified,dried air at 220℉（105℃）for 2-3 hours.

Secondly, basing on the analysis and research to the original measurement system NIM-10000H, the methods of exerting demagnetizing electric current and measuring flux are found out and the device is designed. Experiments are made to prove the feasibility of the device. Although there is feasibility in theory, it should be further research and perfection on making sure the exact electrical current.

第二部分是在对原有检测系统NIM-10000H进行分析和研究的基础上，逐步摸索出施加退磁电流的方法和实测磁通的快速检测方法，并设计出实验用的装置，加以实验验证是否可行，是否能达到快速检测，最终给出初步的结论，该方法可行，只是速度还不够快，而且电流大小的确定还有待进一步的研究和完善。
