【摘要】 <正> 在测定弱磁体磁化率和负载型铁磁性催化剂的磁化强度时,通常是测量样品在磁场中所受的力。产生这种力的原因,是和磁性物质在磁场中力图处于最低能位相联系的,即反磁性物质尽量处于H=H_min的位置。相反,顺磁性物质力图处于H=H_max的位置,这里H_min、H_max分别表示最小和最大磁场强度。更多还原

【Abstract】 In this paper, we report differential method maybe used as absolute method. In applying the method a volume must be obtained of the specimen i.e（?）（gradH²）v≤v₀≈0A procedure for determing the optimum volume of the specimen is also propasedThe method is used to measure the magnetic Susceptibilities of Samples更多还原
