Abstract
The combination of the tangent analysis method (TAM) and the root of the discriminator equation can easily be used to find the bifurcation start point and to avoid steady‐state multiplicity for non‐adiabatic reaction systems. However, its limitation is that it can only be applied to the systems, whose orders of characteristic equations are equal to or less than 3. In this paper, we extend the root of the discriminator equation to a fourth order characteristic equation and derive a clear and explicit formula to overcome the flaw of the combined method. An operating strategy to reach a single steady state with a high reaction conversion is proposed. An example of a non‐adiabatic agitated batch gas–solid catalytic reactor with a two species‐reaction is demonstrated.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
