steepest ascent

The Six Sigma Black Belt able to state the direction of steepest ascent from experimental data.

六西格玛黑带能根据实验数据陈述快速上升的方向.

The optimal condition described as follows: acetone concentration was 62% and extracting temperature was 47 ℃ by the steepest ascent experiment and the central composite design. Under the optimized condition, the highest extracting amount of polyphenols from Humulus lupulus was 47.40 mg · g-1.

通过最陡爬坡试验和中心组合设计试验，优化得到最佳的多酚类化合物提取条件为：丙酮浓度为62%，提取温度为47℃，在此条件下啤酒花中多酚的最大提取量为47.40mg·g-1。

Steepest ascent procedures were applied to define the optimal response region for the three factors, and then, the optimal concentrations for the three factors were determined as urea 0.15%, inoculum 3.05% and initial pH 8.38 using response surface methodology.

用最陡爬坡实验逼近显著因子的最大响应区域后，采用响应面分析法，确定尿素、接种量及初始pH值的最优组合值分别为0.15%，3.05%和8.59。
