你好 我帮你翻译了一下,, 不用怕 不是谷歌 是有道。。。。With the rapid growth of the airline needs, air traffic network increasingly crowded, especially in the weather conditions, airport delays phenomenon reduced capacity is very Civil aviation flight ZhengChangLv year-to-year Meanwhile, airlines to achieve the maximum economic benefits of our enterprise at the airport, all hope for the best, pursue the enterprise of flight schedules maximum economic Leading to peak at the airport, and crowded and made crowded when idle state at the airport and is adverse The aim of this article is to study collaborative ground-holding timeslot switching methods, fully utilize the airport capacity, in both airlines fairness factors is discussed based on how to scientifically and reasonably in the airline company, namely improve time buttress exchanged between time resource utilization rate, and promote airlines involved in the enthusiasm of coordinated Aimed at the ground wait timeslot switching technology, put forward and adopt priority ranking, for different priority flight requirements are different, reasonable let airlines involved in coordination and deals, to get effective time, solve the problem, reduces the time transactions, of flight delays and makes aviation company meet their own
In the aerospace domain, the environment which the flight vehicle structure locates and bad, like the missile end forehead, the solid propellant engine nozzle throat lining and so on all works in the superhigh temperature Uses in these spots when material work, causes own quality loss through the ablation, absorbs and carries off the massive quantity of heats, the impediment quantity of heat According to the hot shielding material thermochemistry ablation mechanism establishment reasonable mathematics aerodynamics model, the analysis volume ablation causes the material performance along with the temperature change rule is extremely Through guards against heat the material interior thermochemistry ablation mechanism analysis to the high temperature environment under, studied the component material ablation using the Eshelby equivalent mixture method - to change the characteristic and the high temperature mechanics performance and the hot physical performance change After the supposition material thermo-chemical reaction the thermal decomposition production the medium statistics uniform distribution, had considered the ablative response produces between the blowhole and the solid phase medium mutual function, forecast the substrate, the enhancement textile fiber, the unidirectional textile fiber strengthened the compound materials the viewing carefully structure and between the macroscopic mechanics hot physics performance change relations, and has carried on the value The findings indicated that,The unidirectional compound materials longitudinal young's modulus weakens along with the temperature increment, and concerns with the warming The model hot shielding material high temperature performance theory forecast and the empirical datum carry on the comparison, finally tallies well, explained the theoretical model is correct, has laid the foundation for the heatproof compound materials hot structure Key word: Guards against heat the compound materials; Mesomechanics; Volume ablation; High temperature performance
