微量松散物料的重力式定量在加工工程工业中越来越重要。由于最终产品经常是由多成分组合而成的,所以微量的定量稳定性对最终产品的质量是起决定性作用的。本文介绍研究与工业中一些不同的应用例子,即使在严酷的生产条件下,也都证明了使用微量定量是成功的。定量原理与差动定量 Gravimetric quantification of loose bulk materials is increasingly important in the processing engineering industry. Since the final product is often composed of multiple components, the quantitative stability of the trace is of decisive importance to the quality of the final product. This article describes a number of different application examples in research and industry, and demonstrates the success of using trace quantitation, even under harsh manufacturing conditions. Quantitative principles and differential quantitative
