This paper introduces the measurement of gradient distribution ofthe pulsed magnetic field using the mini size dual-coil method. The coil is just likea "point", so it can represent the distribution of small magnetic field more exactly.The noncoincidence of the two coils can be compensated by adjusting the "symmetriccircuit". In this paper, the principle of compensation is described. The signals comefrom coil is very weak. For measuring gradient, the outputs of two coils areconnecting in series-opposing, and the total signal is rather weak. Therefore, theinstrument should be sensitive and the resolution of instrument should also be highfor detecting the slight variation of gradient in field. Besides, a lot of data beingcollected in measuring gradient distribution, rapid and automatic measurement isnecessary. According to these requirements a instrument measuring amplitude of pulsesignal is designed. Both the "direct measurement" method and the peak pulse-D. C. comparision method can be used to measure the amplitude of pulse signal withthe instrument. The former method can rapidly and automatically printout the meas-uring data, and the latter one can measure the peak value more precisely. So it'senable to calibrate the first one using the latter method. By matching coils and theinstrument, the reproducibility of measurement is better than ±0.1%. A measuringsystem have been set up, while a vertical milling machine, which can be moved inX, Y, Z three directions, is taken for measuring bench. By means of this systemthe gradient distribution of pulsed field in the gap of the prototype quadrupolemagnet is determined. Measuring results show that the form of gradient distributionof the quadrupole is as a "saddle", and the three dimensions character of this typeof quadrupole is also represented.

本文阐述了利用微型双线圈法测量脉冲磁场梯度的分布形态。微型线圈由于点性好,能较真实地反映微小空间场的分布形态。文中说明了通过调节“对称电路”补偿双线圈的不一致性。微型线圈输出信号微弱。在测量梯度时,两线圈串联反接、输出信号更弱。因此,测量仪器应足够灵敏、分辨率高,且应快速和自动。基于这些要求,设计了测量脉冲信号幅值的仪器,它可同时兼用直读法和交直流比较法两种方法。前者能快速、自动地打印测量数据,后者则有较精确的读数。可用后一方法对前一方法进行校正。仪器与测量线圈配合,测量重复性一般可优于±0.1%。此外,还用了一台能有X、Y、Z三个方向位移的铣床作机械工作台,组成了整套测量系统。用它对一个工艺四极透镜孔中的脉冲场梯度的分布形态进行了测定。测量结果表明透镜孔中磁场梯度分布形态为“马鞍形”。同时还显示了此类透镜磁场的三维特徵。

When the cutting temperature is measured with tool-work thermocouple,its additional thermo E.M.F of the tail of blade is often compensated by using Copper-Constantan compensating circuit,therefore it is necessary to study the errors of compensating circuit.K.J.Trigger,R. K.Compbell,and B.T.Chao,in accordance with a part of their experi- ment,point out that the maximum output of unbalanced voltage is about ±0.02mV,and the error of measuring temperature is ±2°F for cutting steel.In this paper,it is proved through theoretical analysis and experi- mental research that there is limitation on above conclusion.Sometimes unbalanced voltage would be up to 0.34mV;and temperature erorr would be up to(20-30)℃ for this compensating circuit while cutting high tem- perature of blade.The influence of compensating resistance and inter- nal resistance in conductor on unbalanced voltage are analysed. A calculating formula for unbalanced voltage is given and another pair of conductor with smaller error is introduced.

在用刀具——工件热电偶测量切削温度时,常采用铜——康铜补偿电路补偿刀片尾部的附加热电势。因此,研究补偿电路的误差问题是很必要的。Trigger 等人曾根据部分试验指出:在采用铜——康铜组成的补偿电路时,最大不平衡电压输出约为±0.02mv,对于切削钢料来说,测温误差为±2°F。本文通过理论分析和试验研究,证明上述结论是有局限性的。对这种补偿电路,若使用不当,在切削高温合金时不平衡电压有时可达0.34mv,温度误差有时可达(24~30)℃。本文分析了刀片尾部实际温度,补偿电阻及导线内阻对不平衡电压的影响,得出不平衡电压的计算公式,并提出了另一对误差较小的导线,可供选用。
