微定量是几十年来天天都在使用的、勉强实现相应量输出的一种技术。最出名的一些方法之一是有喷射器与弹筒的定量装置,后者装有油、油脂、颜料等等介质,以此借助于压缩空气脉冲排出需要量。所以,可惜精确量只在粗略范围内是有可能的。为了排出但愿再现量,就必须通过若干试验凭 Micro-quantification is a technique that has been used every day for decades and barely achieves the corresponding output. One of the best known methods is the metering device with ejector and cartridge, which is filled with mediums such as oil, grease, paint and the like to pulse out the required amount by means of compressed air. So, unfortunately, the exact amount is only possible in the rough range. In order to expel the hope of reproduction, we must pass a number of tests
