It was confirmed that the analogous relations between unsteady one-dimensional chromatographic process and steady two-dimensional CAC process proposed by Wankat still exist regardless of the bioreaction, and the analogous results were shown. A mathematical relation between the feed and the eluant flowrates was established for keeping the CAC in good operation. The optimization of the hybrid process were also discussed.

从理论上指出了在伴有生物反应时，二维稳态CAC过程与一维非稳态间歇色谱过程仍然存在类比关系，并给出了类比结果，推导了使CAC过程处于良好操作状态时进料及洗脱速率应满足的数学关系，对于生物反应液相色谱分离耦合过程的优化原则也进行了初步探讨。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
