A magneticholder screwed to the wall is a practical way of keeping knives always within reach and isolated from other objects that could dull and dent the blades by knocking against them.
Fourthly, measurement methods of magnetic filed, temperature, transport and magnetization were researched. A sample holder used to electrical transport was prepared.
第四、研究了磁场、温度、电输运和磁化的测量方法，并研制了适合于脉冲磁场测量的样品杆。
