一恒温槽温场稳定性试验
1试验目的
了解恒温槽在稳定状态下，内部各位置之间的温差（温场性能）随时间变化状况，以确定科学、合理的温场测试方法。
2试验设备
四线制A级铠装铂电阻温度计9支；
电测设备（温度巡检仪,型号：
暂缺，编号：
暂缺），分辨力0.001℃；
恒温槽三台，编号和温度范围见表1。

3试验方法
3.1将4支温度计（编号1-4）的底端放置在距液面15cm的水平面上，1支温度计（编号5）的底端置于距液面30cm的水平面中心位置，4支温度计（编号6-9）的底端放置在距液面45cm处的水平面上。
待温度稳定后，测试各温度计数值，每30秒间隔测试一遍。
持续测试4次。
观察各位置点的温度变化幅度。
3.2将4支温度计（编号1-4）的底端放置在距液面15cm的水平面上，1支温度计（编号5）的底端置于距液面30cm的水平面中心位置，4支温度计（编号6-9）的底端放置在距液面30cm处的水平面上，待温度稳定后，测试各温度计数值，每30秒间隔测试一遍。
持续测试4次。
首先计算各位置点的温度变化，最后计算所有温度变化的最大幅度。
