查询词典 energy-efficient

The energy exchange analysis indicates that gliding energy efficiency is dependant on the lift drag ratio of the wings and gliding angle of the hull. Through the calculation in this thesis, it can be concluded that enhancing the lift drag ratio can largely improve the energy efficiency when the gliding angle is in the range of 10to 40 degree, and when lift drag ratio is fixed, there exists a special gliding angle for the maximum of the efficiency, which provide theoretical basis for the design of operating parameters.

通过能量转换分析，得出滑翔机航行效率由机翼升阻比和机身航行角决定，航行角在10~40度范围内，增大机翼升阻比可显著提高航行效率；并由计算得出，在升阻比一定的情况下，总存在一个使滑翔机航行效率达到最大的航行角度，为样机工作参数设计提供了理论依据。

The calculated results with B3LYP/6-31G-DFT show:(1)the molecular total energy of benzofuroxan is lower than that of o-dinitrosobenzene;(2)the activation energy(Ea+=51.0kJ/mol)of forward reaction that benzofuroxan isomerises into o-dinitrosobenzene,is in agreement with the experimental(58.6kJ/mol)provided by reference,and the activation energy(Ea-=4.6kJ/mol)of back-ward reaction is very small.It is concluded thereby that benzofuroxan is more stable than o-dinitrosobenzene.In addition,the corresponding ab initio calculations at the level of HF/3-21G,HF/6-31Gand MP2/6-31G//6-31G were completed,and it was found that the calculated results by B3LYP-DFT method are superior to those from ab initio calculation.
