The survey, which polled 108 private jet owners with a mean net worth $116 million, found that 94% of those surveyed defined luxury as 'for oneself, ' rather than for the masses (2.8%).
Prince and Associates调查了108位拥有私人飞机的人士,他们的平均净资产额在1.16亿美元。调查发现,94%的受访者给奢侈品选择的定义是“给自己的”,而不是“为大众的”(这个选项的比例是2.8%)。
Results showed that the net heat loss on the downstream side of the jet nozzle could reach 20 ~ 30% of total heat flux. Therefore it can not be neglected in calculating the wall temperature.
结果表明,喷管下游端的壁面辐射损失高达壁面总热流的20 ~ 30%,在壁温计算时不容忽略。
