查询词典 batch

间歇萃取精馏是分离共沸物或近沸物的一种方法，由于它结合了间歇和萃取的优点，特别适用于化工、制药、溶剂回收、天然产物提取等产量小，品种多的行业，因此间歇萃取精馏近年来已成为非常活跃的研究和开发领域。

Compared with batch mode, intermittent fed-batch mode improved riboflavin production slightly, the constant rate and glucose-limited fed-batch modes can make a significant increase in both dry cell mass and riboflavin production.

同间歇培养相比，分批流加培养能微弱提高重组菌的核黄素产量，而恒速流加和葡萄糖限制流加均能显著提高菌体量和核黄素产量。
