为了更好地评价半滑舌鳎(Cynoglossus semilaevis Günther)在工厂化循化水养殖模式下的养殖效果及环境可持续性,运用能值理论及分析方法构建了半滑舌鳎循环水养殖模式能值流程图,并对此养殖模式各能值分布进行分析。结果表明:循环水养殖模式环境能值投入只占比1.08 %,能值产出率(EYR)为2.433,环境负载率(ELR)为0.313 4,能值可持续发展指标(ESI)为7.763,表明此种养殖模式已经将农业生产提升至工业化水平,其经济系统发展程度高,生产效率较高;同时该养殖模式极大地减轻了对环境的压力,其可持续性和环境容纳量均较高。

Wind turbine gearbox (WTG), which functions as an accelerator, ensures the performance and service life of wind turbine systems. This paper examines the distinctive modal properties of WTGs through finite element (FE) and experimental modal analyses. The study is performed in two parts. First, a whole system model is developed to investigate the first 10 modal frequencies and mode shapes of WTG using flexible multi-body modeling techniques. Given the complex structure and operating conditions of WTG, this study applies spring elements to the model and quantifies how the bearings and gear pair interactions affect the dynamic characteristics of WTGs. Second, the FE modal results are validated through experimental modal analyses of a 1.5 WM WTG using the frequency response function method of single point excitation and multi-point response. The natural frequencies from the FE and experimental modal analyses show favorable agreement and reveal that the characteristic frequency of the studied gearbox avoids its eigen-frequency very well.
