| 摘 要： | 測定磁棒磁矩的溫度系数时,用了一个电流綫圈以抵消磁矩变化的影响,因而簡化了計算工作。測定磁棒的綫膨胀系数时,利用現有設备及一个比較簡单的装置,得到了相当准确的結果。測定磁棒感应系数使用的螺綫管（納尔逊法）中磁場的均勻性,在纵方向及横方向都作了核算,因而对它們的影响,能进一步加以估計。綫圈及其他磁强計附加装置也还准确而簡单易制。

| Abstract: | For the determination of the temperature coefficients of magnets, an improved system for quickly stabilizing the temperatures is used. A current coil to compensate the magnetometer deflections due to the change of the magnetic moments, simplifies the calculating work. In the determination of the coefficient of linear expansion of magnet, a simple device is used in conjunction with the available instruments and sufficiently accurate results are obtained. In the determination of the induction coefficient of magnet, the uniformity of the field of a solenoid（Nelson's method） is examined by calculating the field at several points in the coil, thus its effects can be estimated more surely. The magnetometer attachment for the determination of the induction coefficient, which is not complex and rather accurate, is described. |
