Abstract : on the basis of the analysis about noise sources of the air compressor, it shows that air dynamic noise is primary one. according to the theory of fluid mechanics, the mathematics model of the air compreesor air dynamic noise is found, which shows the relationship between the sound power level and other parameters. the knowing noise of the air compressor " s air dynamic is of low frequencies. the reliable data is provided for the noise and vibration control
文摘:通過對空壓機噪聲源的分析，確認空壓機噪聲源中的空氣動力性噪聲為最強；由流體流場的聲學理論，建立空壓機動力性噪聲源的力學模型，它表明聲功率與其它參數的關系；並知空壓機的空氣動力性噪聲呈低頻特性，這為噪聲及振動控制提供了可靠的依據 -
The wavelet method used in economic forecast depends on its " mathematics microscope " property. it does the layer analysis and forecast to indicators. it can improve forecast precision, what ' s more it can search and express the structural feature of data such as development cycle, second cycle, especially to some sudden change data which will provide effective and reliable warranty to the complexity and violent fluctuant data indicators in enterprise
基於小波進行經濟預測的方法依靠其「數學顯微鏡」的特性，對待分析的預測指標進行逐層分析和預測，在提高預測精度的基礎上，能對分析數據對象的結構特徵進行挖掘，分析數據特徵如發展主周期、次周期等，尤其對具有突變性質的數據具有很好的表徵分析能力，這對于企業中復雜的變動劇烈的數據指標的預測能提供有效可靠的保證。 -

本文運用系統學理論和模糊數學方法分析了隧道施工裝巖運輸過程中人機環境諸因素對施工安全的影響，確定了運輸系統層次結構及安全評價指針的權重，為隧道施工安全評價提供了可靠依據。 -
Taking account for the multi - factor, multi - object characteristics of the inland waterway network distribution, the obscure connected deciding method of the inland waterway network distribution is proposed for the first time, with the application of obscure mathematics theory and grey system theory. the mathematical and modeling characteristics of this deciding method not only enforce the scientific characteristic of the network decision but also stimulate the development of the inland waterwayl network decision. the obscure connected deciding method takes an overall account of the connection degree so that the deciding result is reasonable and reliable
根據水運網路布局多因素、多目標的特點，運用模糊數學和灰色系統理論，首次提出了航道網路布局模糊關聯決策方法，該決策方法的數學化、模型化，加強了網路決策的科學性，促進了航道網路決策的發展，模糊關聯綜合決策方法全面考慮了由關聯度作出的決策結果是合理的、可靠的。
