另外，区间还能通过离散的选择方法如选择聚合和最大区别缩放等来直接从消费者偏好做模型。
Alternatively, segments can be modelled directly from consumer preferences via discrete choice methodologies such as choice-based conjoint and maximum difference scaling.
这意味着如果你在空间中作两条平行线，它们不会聚合或离散，只会一直保持相等的距离无限延伸下去。
That means that if you draw parallel lines in space, then they will remain the same distance apart along their infinite lengths instead of converging or diverging.
利用变分法推导了连续与离散情形聚合物驱最优控制问题的必要条件。
The necessary conditions of the OCP for polymer flooding were deduced by using calculus of variations. Both continuous and discrete cases are studied.
