Results of calculation indicate that the bubble & dew points may be reduced extremely, but the relative volatility rises slightly and the separation of them is affected hardly by decreasing pressure.
计算结果表明，减压可大大降低乙苯—苯乙烯物系的泡、露点，但相对挥发度增加甚微，对其分离的难易程度几乎无影响；

However, the tech cycles were much deeper than the general economic cycles, and as a result, the company was really measuring relative volatility, not performance.
