磁性沸石既具有吸附性能又具有磁性能,因而在催化应用和环境修复后可用磁场将沸石粉末分离出来[6]。
Magnetically modified zeolites offer the advantage of easy separation recovery of powdered zeolites after catalytic runs or environmental remediation by means of an applied magnetic field [6].
他发现有些材料在受到磁场作用时会改变其电阻性,这种效应也可被应用于回读被记录的数据。
Thomson found that the electrical resistance of some materials changes when a magnetic field is applied to them. This effect can be used to read back what has been recorded.
应用物理杂志的介绍的这一新结果,意味着NIST的迷你传感器可以用来进行磁场测量,这种测量可补充或替代心电图。
The new results, described in the journal Applied Physics Letters, suggest that NIST mini-sensors could be used to make magnetocardiograms, a supplement or alternative to electrocardiograms.
