yield of extraction

基本解释

If the liquid level above the pump intake, it is impossible to maximum yield of extraction wells.
若液面高于泵吸入口，那么井不可能以最大产量开采。
In single factor experiment, the highest extraction yield of ultrasonic extraction is 16.61%, which is higher than traditional extraction.
在单因素试验中超声波提取的粗阿拉伯半乳聚糖最高提取率为16.61%，比传统浸提法高。
Methods The procedures were evaluated for yield of extraction. the content of the przewatanshinquinone and optimized by orthogonal design with table L9(34).
方法用正交试验设计优化最佳提取条件，以浸膏得率和丹参素含量为指标，选用L9（34）进行煎煮条件的选择。
