【摘要】 基于温度对反应速率的影响建立了热电池加速寿命试验方法,并用数学分析软件对实验数据进行拟合,并建立了一元四阶回归方程;使用该回归方程设计热电池,可实现对热电池贮存寿命的控制和预测。实验发现热电池工作寿命随贮存时间的增加下降到一定限度后,又会有一定程度的恢复,不同于预期的线性下降或渐近线下降的方式。更多还原

【Abstract】 The thermal battery’s accelerated aging experiment based on the Arrehnius equation.The experiment datum were fit-ted by mathematic analysis software. The regression polynomial equation had been established.And the battery’s design could be controlled by it. At the same time, storage life could be predicted by the equation. The experiment showed that the ther-mal battery’s operating life gradually decreased to the lowest point and then would rebound to some degree. This phenomenon was different from the expected linear decline or asymptote decline.更多还原
