在间歇操作中，精馏塔进料是间歇进行的，即，先向塔内填充一批料，然后开始精馏过程。
Thus, the perturbation model is updated in a batch-wise manner. After completion of each batch, a batch-wise perturbation model is identified linearized around the control trajectory for that batch.
每完成一个批次就利用新得到的数据对模型进行更新，该更新的模型也是在前一批次的控制轨迹基础上进行线性化得到的。
As far as the feeding mode was concerned, constant-speed feed was more effective than batch-wise feed. The abnormal cellular form was often observed when glucose was batch-wise fed.
