Like the UNIFAC group-contribution equation of state, it performs satisfactorily in the VLE prediction of systems containing polar components, including VLE under high pressures.

用此法预测了含极性组分体系常压到较高压力的汽液平衡，结果良好，与UNIFAC基团贡献状态方程的结果相当。

Based onthe molecular QCLC model, a group contribution quasi-chemical local composition model is proposed, in which polar molecule is divided into several non-polar functional groups.

本文在前文的分子模型基础上，提出了似化学局部组成的基团模型，可用于极性分子混合物申组分活度系数的预测。

The agency said worse case scenarios, including the contribution of polar ice melt and thermal expansion, could result in much higher levels occurring but these were now thought to be unlikely.
