結果：通過對歐前胡素、糖類成分、氨基酸、浸出物、灰分和水分的分析測定，結果表明：北沙參採收以10月份為宜；藥材加工以趁鮮水洗、帶皮切片曬干或低溫烘乾最佳；追肥以酵素菌高效生物肥效果最好，其次為硫酸鉀復合肥、硫酸鉀；栽培品種「白銀條」的糖類成分和浸出物含量最高，而「大紅袍」的歐前胡素含量最高；當年開花和當年結種的北沙參質量較差；北沙參藥材質量以萊陽胡城產最佳，而河北安國和內蒙古產的則較差。 -
The automation of coal flotation has been wandering for many years in china. the production efficiency is relatively low because of the feed forward control which adds the flotation reagent based on the fine coal in feed slurry, ignoring the quantity and quality of the products. aiming at this problem, method of measuring the flotation technical parameters was studied, the slurry level meter and the slurry ash - measuring device were worked out, and the computer control system of the coal flotation was designed. the feedback control was realized by using the fuzzy logic control control technology to regulate the reagent addition and the slurry level in the flotation tank according to the concentrate ash content detectedby the coal slurry ash - measuring device developed. the industrial experiment indicates that the performance inedxes of the coal slurry ashmeasuring device have come up to the advanced levek of the world. the application of the detection and control system in huaibei coal preparation plant results in a high concentrate recovery, a decrease of the reagent consumption, ensuring a highly efficient operation
浮選自動化在我國多年來徘徊不前，一直採用根據入浮煤漿中的干煤泥量來確定加藥量的前饋控制方法，而不直接以產品的數質量指標作為控制目標，導致浮選生產效率較低.針對上述問題，研究了浮選工藝參數的檢測方法，開發了浮選漿位儀和煤漿測灰儀，設計了浮選計算機控制系統，它根據煤漿測灰儀旁線檢測的精煤灰分，運用模糊控制技術，通過調整浮選藥劑添加量和浮選機漿位，來實現浮選過程的反饋控制.工業性試驗表明，煤漿測灰儀的性能指標接近國外先進水平.煤泥浮選測控系統在淮北選煤廠的現場使用，使浮選生產在精煤灰分合格的前提下，得到了較高的產率，並降低了藥劑用量，從而保證選煤廠高效率地運行 -
