Interval Newton algorithm is used extensively in the calculation of chemical engineering such as the determination of phase stability, reactive azeotropes, robust process simulation, reliable parameter estimation, etc.

• 由于区间牛顿法强壮的全局收敛性和同时求得多个解的能力使得区间牛顿法广泛地应用在化工计算领域，如：相稳定性分析、反应共沸物的判断及组成确定、稳态过程模拟、参数估计等等。
