At the same time, the fouling mechanism of membranes given in this thesis can give a reasonable explanation on the change of membrane performance. Our results show that the magnetization of membranes can effectively improve the anti-fouling ability of the PAN- Fe_3O_4 membrane. The obtained result may give insight to the development of new membranes with a good anti-fouling performance in the filtration of blood solution. No chemical bond was found between PAN and Fe_3O_4 in the membrane at room temperature. The addition of Fe_3O_4 can improve the temperatures of dehydrogenated reaction and decomposition of PAN but dot change the glassy transition temperature. The resistance against acid is stronger than the resistance to base for a PAN- Fe_3O_4 membrane.

结果表明在PAN- Fe_3O_4超滤膜制备过程中使用外加磁场作用能有效提高膜的耐污染能力，这一结果为开发适用于血液处理的耐污染超滤膜提供了一种新途径；在PAN- Fe_3O_4超滤膜中，四氧化三铁与PAN在室温下没有形成化学键，也不存在官能团之间的相互作用；添加Fe_3O_4对膜的玻璃化温度没有影响，但能提高PAN环化脱氢反应的温度和分解温度；PAN- Fe_3O_4超滤膜的耐酸性强于耐碱性，在pH值为10以上的溶液中由于水解作用而溶解，使得膜失去使用价值，膜的耐酸性与酸的种类、浓度和氧化性有关。

Gaolan Hill section is in the southern Lanzhou City with a total thickness of 240 m. 422 paleomagnetic block samples were obtained from the field with an approximate spacing interval of 0.5 m. All samples were demagnetized in a thermal demagnetiser systematically, and then the Nature Remanent Magnetization was subsequently measured using a superconducting magnetometer from room temperature to 500 ℃ in 50 ℃ steps.

When the field is applied along the wires, the hysteresis loop exhibits a shear effect, which always means an equivalent demagnetizing field. It comes from the dipole interaction between the wires. The coercivity of the Fe nanowire arrays in the diameter of 16nm is 2000Oe at 300K, and it will increase to 2800Oe when the temperature decreases to 5K.

不同直径的Fe纳米线的磁滞回线均表明沿着线的方向均表现出shearing effect，表明其中存在一个等效退磁场，它来源于线间的偶极相互作用。16m的Fe纳米线的矫顽力室温下为2000Oe，5K时则达到2800Oe。
