摘要:
地球内部的物理-化学性质与其高温高压环境休戚相关,其结构、成分、演化通常通过高温高压实验来模拟,如何提高高温高压实验中温度测量的准确性非常重要。通过系统总结目前大压机高压实验中的加热方法、温度测量、热电偶性质及实验组装中温度分布特点,并对活塞-圆筒压机高压实验中温度和加热功率关系、不同实验条件下热电偶行为、六面顶压机上直筒型加热器中温度分布情况进行了研究,试图探讨提高高温高压实验中温度测量准确性的方法。结果表明:为达成大压机高压实验中准确温度测量的目的,首先必须了解研究体系的温度范围、压力区间以及相应的物理-化学性质;然后在此基础上合理选择高压设备、实验组装、加热器形状与尺寸、测温方法。需要警醒的是,大压机高压实验中的温度测量受高压设备、加热器形状与尺寸、绝热材料的种类与数量、热电偶的类型及其布置方式与位置等众多因素的影响。总之,了解并综合考虑这些影响因素对提高高温高压实验中温度测量的准确性非常有帮助。
Abstract:
The physical-chemical properties of the Earth’s interior are critically dependent on its high-P and high-T conditions, which are usually simulated with high-P and high-T experiments. How to improve the accuracy of the T measurement at high-P condition is thus crucial. This paper introduces some common aspects of the heating techniques, methods of temperature measurement, properties of thermocouples, and features of temperature distribution in the high-P cell assembly used on different large volume presses, provides some new experimental data about the power-temperature relations in the piston-cylinder apparatus, about the behavior of different thermocouples under different experimental conditions (especially under different oxygen fugacities), and about the temperature distribution in the cell assembly (with straight wall heater) in the cubic press, and tentatively explores how to improve the accuracy of the temperature measurement in the large volume press. It is suggested that in order to achieve a better temperature measurement, researchers must understand the target system, it P-T ranges, and the purpose of the present study, on which the type of the large volume press, the arrangement of the cell assembly, the shape and size of the heating element, and the way of the temperature measurement are based. We emphasize that the temperature measurement in the large volume press can be affected by a large number of complicated factors. A good understanding of these factors and taking them into consideration in designing the cell assembly will result in higher accuracy in the temperature measurement in the experiments carried out with the large volume press.
