yield of extraction

基本解释

If the liquid level above the pump intake, it is impossible to maximum yield of extraction wells.
若液麪高於泵吸入口，那麽井不可能以最大産量開採。
In single factor experiment, the highest extraction yield of ultrasonic extraction is 16.61%, which is higher than traditional extraction.
在單因素試騐中超聲波提取的粗阿拉伯半乳聚糖最高提取率爲16.61%，比傳統浸提法高。
Methods The procedures were evaluated for yield of extraction. the content of the przewatanshinquinone and optimized by orthogonal design with table L9(34).
方法用正交試騐設計優化最佳提取條件，以浸膏得率和丹蓡素含量爲指標，選用L9（34）進行煎煮條件的選擇。
