温室甜瓜加氧灌溉综合效益评价（Evaluation of Comprehensive Benefit in Greenhouse Muskmelon under Aeration Irrigation）
温室甜瓜 加氧灌溉 综合效益评价
2010/12/28
采用基于客观赋值法的熵权信息法与主观赋值法相结合的综合评价方法对不同加氧频率处理温室甜瓜综合效益进行评价，并对各加氧处理进行综合效益排序。结果表明，2天1次的加氧频率处理综合效益最好，每天1次的次之，不加氧处理的综合效益优于3天1次和每天2次处理，沟灌处理的综合效益最差。加氧灌溉均可以不同程度地提高温室甜瓜的产量和品质，但由于加氧处理增加了电费及滴灌设备及管件等资金投入，致使一些加氧处理综合效益降...

An adequate supply of dissolved oxygen (DO) is essential for the survival of aquatic organisms. Hydraulic structures can increase DO levels by creating turbulent conditions where small air bubbles are...
基于温度—含氧量的全自动堆肥通风控制系统设计（Design of Temperature/Oxygen Concentration-based Aeration Control System for Aerobic Composting）
堆肥 通风 温度 含氧量
2009/8/11
采用工业计算机和下位机的监测控制方式，开发了基于温度-含氧量的全自动堆肥通风控制系统，并实现了软硬件的配套设计。运行试验表明：采用该工艺堆肥，时间一般为2周，高温期（55～65℃）可维持9d以上，能有效杀灭病原微生物，产品稳定性好；可在整个堆肥过程中实现自动在线监控堆体温度、含氧量和湿度，运行稳定。
Selection of Co-Substrate and Aeration Conditions for Vanillin Production by Escherichia coli JM109/pBB1
Escherichia coli vanillin ferulic acid
