I would like to ask for the translation of a chemical term related to “connodal”
Thread Content
Could you please advise on how to translate the following phrases? Connodal tie lines and plait points: From a physical perspective, the most important elements are the connodal lines and tie lines. Korteweg states that, unlike spinodal lines, there is no analytical expression for connodal lines. However, knowledge of spinodal lines and plait points, along with careful application of the general theory of folds, enables one to understand the development of connodal lines and tritangent planes. ————————“Phase equilibrium in binary mixtures” Thank you for your guidance!

It seems to be related to phase diagrams: Plait point: eutectic point; Tie line: a line that connects two equilibrium points within a multiphase region in a phase diagram. The connodal curve appears to be a nodal curve.
That’s how it should be translated! Thank you! Reference: Bi-nodal line: The curve shown in the diagram. The area below the bi-nodal line is the homogeneous region, while the area above it is the two-phase region, namely ATPS. Tie line: A straight line connecting two points on the bi-nodal line. Information reflected by the tie line: A. Lever rule: Each point on the tie line corresponds to two phases with the same composition but different volumes. The volumes of these two phases approximately follow the lever rule. B. Difference in properties: The length of the tie line serves as a measure of the relative difference between the two phases; the longer the tie line, the greater the difference in properties between the two phases, and vice versa. C. Critical point: When the length of the tie line approaches zero, the difference between the two phases disappears, and the distribution coefficient of any solute between the two phases becomes 1.
