在大型的石油化工生产装置上,流量的检测与控制是比较成熟的技术;然而要实现微小流量的控制却并非易事。目前在我国的各种小型及微型实验装置中(进料量为每小时几十至几百毫升),绝大多数仍是靠人工
In large petrochemical plants, flow detection and control is a relatively mature technology; however, it is not easy to control the flow of small quantities. Currently in our country a variety of small and micro experimental devices (feed rate of tens to hundreds of milliliters per hour), the vast majority are still relying on artificial
