评价一种磁性制冷材料的性能好坏，对其进行绝热温变测试是很重要的一步。
Adiabatic temperature changes testing is one of the most important way to evaluate the cooling ability of the material.
用粉末X射线衍射表征材料的相组成，用扫描电镜(SEM)观测样品形貌，用直接法测量材料的绝热温变。
The samples' structures were characterized by using powder-X-ray diffraction (XRD) and the samples' morphologies were observed with SEM and the adiabatic temperature changes were determined directly.
为此，利用基于BWRS状态方程的绝热节流模型计算了板876储气库回采天然气的高压节流温变等焓线。
At present, an adiabatic throttle model based on BWRS equation of state is used to obtain the temperature variation of Ban876 UGS's RNG at constant enthalpy condition.
