The community composed of Elaeagnus mollis as the constructive species is one of the typical vegetation types in the hills and lower-mountains of southern of Shanxi.
机器翅果旋转大概每秒15次，并可以导航通过小的地方并且避障，比大的机器如直升机或者飞机更加突出其优点。
The robotic samara spins about 15 times per second and can navigate through small areas and avoid obstacles, giving it advantages over larger vehicles such as helicopters and airplanes.
翅果：指坚果或瘦果中果皮延伸成翼状，以利于风媒传播的果实类型。如白蜡树的果实(欧洲白蜡树)。
Samara a nut or achene whose pericarp is extended to form a wing for wind dispersal, e. g. Ash (fraxinus excelsior).

Samara a nut or achene whose pericarp is extended to form a wing for wind dispersal, e. g. ash ( fraxinus excelsior )
然而，通过自由落体测试，研究者可以量化的测量翅果的飞行动力并且用得到的信息数据来控制翅果的自旋和飞行轨迹。
However, through free-fall testing, the researchers could quantitatively measure the samara's flight dynamics and use this information to control the samara's autorotation and flight path.
正如你所看到的，每个春天枫树的翅果都会大批地盘旋而下，它们纸一样的薄翅能够使自己停留在高处，这样它们就能找到一个适合生根发芽的好地方了。
Maples make those little whirlybird seeds you see spiraling down in droves each spring. Their papery little wings keep them aloft so they can find a good place to germinate and make a new maple.
