It is indicated that, when a two - speed motor is used for driving oil transfer pump, the motor with the characteristic of torque reduction on square rotary speed should be chosen ; the working economy of the variable speed pump is restricted by the characteristic curves of pipeline resistance, and its speed control range is restricted by the pipeline resistance characteristic curve, the pressure head needed by the system and the working characteristic of the pump ; when several pumps work in parallel, the pump with better performance should be changed into speed - variable pump
指出雙速電動機用於輸油泵的調速時，應選用轉矩按轉速平方降低特性的電動機；調速泵的運行經濟性受到管路阻力特性曲線的限制，其調速范圍受到管路阻力特性曲線、系統所需揚程和泵運行特性的限制；在母管制系統中把部分定速泵改為調速泵時，應將性能較高的定速泵改為調速泵。 -
In this paper introduced the study of fuzzy controller which was used for co2 supplying control from co2 source - high - pressure steel tin to culture box, studied the control of relative humidity and co2 concentration in the culture box and effects of co2 enrichment ( enrichment concentration was 900 - 1100mol mol - 1 ) on the growth of chrysanthemum plantlet and tried to clean the air in the culture box by cycling the results indicated that this environment control system operates normally and reliably. it can keep the co2 concentration and relative humidity in setting scope ; it is good to the growth of the culture plantlets to clean the air in culture box by cycling ; co2 enrichment can promote the growth and photosynthetic and can increase the percentage of shooting the number of new leaves of the chrysanthemum plantlet cultured under co2 - enriched condition is 1. 85 times of the plantlet cultured under co2 - nonenriched condition ; the number of the roots of the chrysanthemum plantlet cultured under co2 - enriched condition 5. 67 times greater compared with the plantlet cultured under co2 nonenriched condition
結果表明：所研製的無糖組培微環境co _ 2增施監控系統工作正常、穩定、可靠，能有效地將組培箱內的co _ 2濃度及其相對濕度控制在設定范圍內；用箱外循環法對箱內氣體凈化處理后，改善了組培箱內的氣體環境，有利於組培苗的生長發育； co _ 2富集環境中，組培苗生長健壯、發育良好，生根率顯著提高，根系發達。本實驗條件下，處理組菊花組培苗的新增葉片數是對照組的1 . 85倍；處理組的根總長是對照組的10 . 6倍；處理組根數是對照組的6 . 67倍。 -
The research indicated that, if the secondary combustion chamber was looked on as a controlled object, with the adjusting valve as a input, the pressure and the temperature of a selected point on the inside wall of the combustion chamber as outputs, then such controlled system would be a strongly non - linear, time varying system with number of random disturbances, which resulted in huge difficulty to build an analyzed mathematics model for the spray burning of the liquid fuel, so that classic control methods were all invalid
研究表明，若將rbcc發動機的二次燃燒室視為一個控制對象，同時以燃燒室內壁面取定點處的壓強、溫度和調節閥的開度為輸入輸出變量，則該系統將是輸入?輸出特性非線性很強、隨機干擾嚴重的復雜時變系統。這導致建立燃油噴霧燃燒具體模型的很大困難，從而宣告了經典控制方案的失效。 -
Hydrogeological control of coalbed methane in zhungaer basins were also simply discussed from the influence both hydrogeological conditions on cbm accumulation ; cbm diffusion and seepage flow in multiphase medium coal. it was indicated that the feasibility of occurring cbm pool which was sealing off by hydraulic pressure maybe very small. qualitative and quantitative recoverability comprehensive assessment of every jib and j2x coal reservoirs region w
在準噶爾盆地煤層氣成藏有利條件研究的基礎上，初步預測本區煤儲層成藏最有利的層系是侏羅系西山窯組， j _ 1b煤儲層在南緣東部為有利區、準東為較有利區； j _ 2x煤儲層在南緣東部、準東為有利區，在南緣西部、西北緣為較有利區。
