| 6. | 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 结果表明:所研制的无糖组培微环境co _ 2增施监控系统工作正常、稳定、可靠,能有效地将组培箱内的co _ 2浓度及其相对湿度控制在设定范围内;用箱外循环法对箱内气体净化处理后,改善了组培箱内的气体环境,有利于组培苗的生长发育; co _ 2富集环境中,组培苗生长健壮、发育良好,生根率显著提高,根系发达。本实验条件下,处理组菊花组培苗的新增叶片数是对照组的1 . 85倍;处理组的根总长是对照组的10 . 6倍;处理组根数是对照组的6 . 67倍。 |
| 7. | A new method is developed to predict the temperature distribution of cooling - plate with non - uniform heat load on the surfaces , meanwhile , two types of cooling - plate used in the environment control system of airplane are studied experimentally under conditions of different reynolds number of air and surface heat loads 摘要提出了一种新的冷板简化数学模型,把翅片折合成导热系数?各向异性的等效厚度层实芯板,将冷板与空气的对流换热作?等效层的稳态导热问题,计算了表面热源非均匀条件下冷板的温度分布。 |
| 8. | In metro system , if the absorbing resistor of the vehicle absorbs the regenerative energy during the train operation , the problem of temperature rise will occur in tunnel and platform , and this will consequently increase the load of environment control system in station , increase considerably the energy consumption and the construction & operation cost 摘要在城市轨道交通中,如果采用车辆吸收电阻吸收列车运行过程中的再生能量,则将带来隧道和站台内的温升问题,同时也增加了站内环控系统的负担,造成大量的能源浪费并使城市轨道交通的建设费用和运行费用增加。 |
| 9. | On the basis of analysis of pre - launch satellite ' s requirement to the environment in different stages in addition to the current state and defects of the satellite environment control system , the paper presents a new concept and specific method to design a new satellite environment control system by applying fuzzy logic theory . with the design and simulation of intelligent satellite environment control as the highlight , the paper illustrates that the basic means to realize the intelligent control is to design a fuzzy logic - based satellite environment controller 本文分析了卫星在发射场不同阶段对环境的要求,以及目前发射场卫星环境控制系统的现状及存在的问题,提出应用模糊逻辑控制理论,设计新的卫星环境控制系统的思路及具体设计方法,本文的重点是卫星环境的智能控制系统设计和模拟仿真,实现卫星环境智能控制的基本途径是设计基于模糊逻辑的卫星环境模糊逻辑控制器。 |
