1949年以前南滿洲鐵道也有這種車軸排列的蒸汽機車，形式是dk1型和dk2型。On the point of system, this paper mainly studies the optimal distribution of load in the machines of irrigation and drainage pumping station, the mathematical model and it ' s solution are studied among the machines in pumping station with two types of axial pump : full regulation or semi - regulation. this paper also studies the problems of the optimal day - operation of pumping station and the economical operation of grading pumping station. at the end, jiangdu pumping station is taken as a practical example to show the theory on economical operation of irrigation and drainage pumping station
本文從系統的觀點出發，以排灌站機組間負荷的優化分配研究為主，分別對全調節和半調節軸流泵兩種泵型的排灌站機組間負荷優化分配的數學模型及其求解方法進行了研究，同時對排灌站最優日運行方式及梯級泵站的經濟運行也進行了初步探索，最後以江都排灌站為例，建立了排灌站經濟運行的實用模型。They are mainly used in manufacturing plants for ventilation or delivering gaseous materials and products thus they are considered the necessary equipment in ventilation, dust collection, acid and odor removal. there are numerous types of domestic products but most are exhausting fans, radial fans, vortex fans and axial fans. the technology controlled by domestic companies has been elevated from earlier dependent on international companies for technical assistance to self - sufficient in manufacturing
除臭設備及焚化爐等設備不可或缺之一環，目前國內所產制之抽送風機種類繁多，而以抽風機、徑向式送排風機、渦輪式送排風機及軸流式送排風機居多，製造廠商之設計製造能力已由早期的仰賴國外技術支援而提升至相當之自製程度，目前國內所產制透浦式送風機之最大處理風量可達By using of the richness, diversity and evenness indices, combined with twinspan, dca, dcca, multi - factors regression, correlation analysis techniques and so on, species diversity and diversification mechanism were studied. the communities were classified into eight types by twinspan. the first axis of dca indicated basically the diversification of soil water, while the second axis indicated basically the disturbance degree by people. the correlations between n, organic matter, elevation and the first axis are negative association, and the others are positive
通過豐富度指數、物種多樣性指數和均勻度指數，結合twinspan 、 dca 、 dcca排序，多元回歸和相關分析，研究了物種多樣性及其變化機制，把植物群落分為8個群落類型；物種多樣性指數的dcca第一軸基本上反映了土壤水分的變化，第二軸基本上反映了人類對群落的干擾程度，物種多樣性指數隨土壤水分的增加而增大，隨人類的干擾程度的增加而減小。System is coordinated controlled based on serial communication between the computer and plc. the followed variables are controlled : the rotational speed of the seeding device driven draft, the operation of the converter, stability and speed of the convey belt, and inclination of the test platform, which is done to simulate actual working condition of seeder
設計了基於串列通訊的微機與plc集成控制方案，控制內容包括：排種器驅動軸轉速控制、變頻器的控制、傳送帶的穩定性及速度控制、工況模擬過程中的試驗平臺傾斜位置的自動控制等。In the process, aiming at the rare bearing oscilation lift in 600mw magnetizing exciter, the several conclusions given by the expert system are examined, diagnosed and treated
對較為少見的600mw勵磁機軸承振動爬升故障，在長期工作經驗的基礎上，逐一排查「專家系統」判斷出的多種結論，成功地進行了分析診斷和處理，確保了設備的安全運行。分享友人
