硝酸纤维素膜的制备与应用研究进展

硝酸纤维素膜,俗称NC膜,是一种极具发展前景的材料,具有良好的高蛋白结合能力、高机械强度、耐化学腐蚀性、耐高温以及粘接强度高等优点,本文主要介绍硝酸纤维素膜的制备、应用以及国内外发展情况,最后对未来发展做出了展望。

MAGNETIC PROPERTIES OF THE ALLOYS (Nd_(1-x)Tb_(x))_(16.7)Fe_(75.5)B_(7.8) WITH x = 0-0.4

Using a high pulsed magnetic field system up to 200kOe,we have investigated the magnetic properties of (Nd_(1-x)Tb_(x))_(16.7)Fe_(75.5)B_(7.8)(x=0,0.05,0.1,0.2,0.4)at a temperature range 77-450K.The results show that the spin reorientation temperature Ts decreases with the increase of x.
