步冷曲线 meaning in English
cooling curve
Examples
- In experimental research , the s - l - e of eleven binary system including fatty alcohol / fatty acid , n - octadecane / fatty acid , n - octadecane / fatty alcohol system were determined by cooling curve . at the same time , the s - l - e of one ternary system of n - octadecane / fatty acid / stearic acid was measured by pseudo - duality , and t - x phase diagrams of these systems were drawn
在实验的研究中，采用步冷曲线法测定了12醇-羧酸系列、部分18烷-羧酸体系、 18烷- 12醇体系共11组体系的二元固液相平衡关系，同时采用拟二元法测定了18烷-硬酯酸-月桂酸体系的三元固液平衡关系，绘制了这12组体系的t - x相图。 - This article choosed out organic phase change materials , and , the solid - liquid - equilibrium of eleven binary system including fatty alcohol / fatty acid , n - octadecane / fatty acid , n - octadecane / fatty alcohol system were determined by cooling curve , and , t - x phase diagrams of these systems were drawn . the result shows that all these systems are simple eutectic , at the same time , the entropy of phase change of every system in the eutectic point is determined by using differential scanning calorimetry ( dsc ) . and n - octadecane / fatty acid systems were calculated theoretically
本文初选出部分有机相变贮能材料，采用步冷曲线法测定了12醇-羧酸系列、 18烷-羧酸系列、 18烷- 12醇体系共11组体系的二元固液相平衡关系，绘制了这11组体系的t - x相图，测定结果表明，这几组体系均为简单低共熔体系；同时利用差热扫描量热法( dsc )对上面各组体系低共熔点处的相变焓进行了测定；并对18烷-羧酸系列进行了热力学理论预测。
