Slower cruising — at about Mach 0.7, or seven-tenths the speed of sound, which is 5 percent to 10 percent slower than today's aircraft — and at higher altitudes, to save fuel.
更低速的巡航——大约0.7马赫，即音速的十分之七，比今天的飞行器低5 - 10%——并且飞行于更高海拔以节约燃油。
The yield of UFD has exceeded 10% using water or ice as preserving media, which is more applicable than Mach effect charge.
用水和冰作为保护介质可使UF D得率超过10%，比利用马赫效应装药更适用于实际生产。
