【摘要】 对自动真空量热仪的测温电路进行了改进。设计出了新的二级放大的测温电路,对温度进行了精确标定。结果表明,改进后的电路有较好的抑制噪声的能力,使量热仪的测量精度得到了提高。
【Abstract】 The circuit of measuring temperature in the automatic vacuum calorimeter is improved. Based on the two-stage magnifying and demarcating temperature scale, new circuit for measuring precise temperature is designed. The results indicate that improved circuir has better ability to restrain the noise and the precision of automatic calorimeter is increased.
