四翼飞机

The aircraft also has six (four under-wing and two wingtip) pylons to carry various air-to-air and air-to-ground weapons.

飞机也有六（四个在机翼下和二个在翼尖）挂架携带各种不同的空对空和空对地武器。

Earhart's efforts paid off and she broke many records, several that had nothing to do with her being a woman: she set an altitude record of 18,420ft in 1931, a feat she followed by becoming the first person to cross the US by autogyro (a hybrid of plane and helicopter).

埃尔哈特的努力没有白费，她打破了许多记录，几个毫不相干的她是个女人：她于1931年成立的一万八千四百二英尺高度纪录，她的壮举，成为了第一个跨越美国的旋翼后（1飞机和直升机的混合）。

It adopted the integration of non-wings are tail wing configuration to fly from nose to tip for the acute angle into, but from top to bottom is curved arch of the fixed front, for the front straight edge of the wing after the double-W, There are four pairs of a combination of aileron, elevator and the flap functions to manipulate the face, with its own aircraft and more than 4 degrees fly-by-wire flight control system to complete match.

该机采用了翼身融合的无尾飞翼构形，从机头至翼尖为成锐角、但上下是拱弧形的固定前缘，前缘为直线，机翼后缘成双W形，有四对综合了副翼、升降舵以及襟翼功能的操纵面，与飞机本身的4余度电传操纵系统相配合完成飞行控制。

Four new advancements – algae biofuels, fuel cell vehicles, blended wing aircraft and the electric jeepney – present compelling opportunities and unique challenges for the future.

第二集的《未来之都2050》，Dan Kammen教授等科学家研究如何让汽车减少排放二氧化碳，并提出四个新解决办法：海藻生物柴油、燃料电池车、电子车及翼身合一飞机，为我们未来而战。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
