部分蜣螂干脆居住在粪便当中,其他蜣螂用自己的后足将粪便滚成完美的球形,进行距离的运输,直到到达它们埋藏粪球的地方。
Some species simply live in the dung, while others form perfectly spherical dung balls, which they roll with their hind legs, often over large distances, to a place where they can bury it.
他们还计算出随着旅行距离的增大,风险也将随之变大。
They also calculated that the longer your journey takes, the higher your risk becomes.
安装了这些任务装备的HC-130J飞机将具有更强的任务能力,同时可以改善燃油效率、提高有效性、增加飞行距离和时间。
The mission-equipped HC-130J aircraft provide increased mission capability with improved fuel efficiency, higher availability, and greater range and endurance, says a representative.
本文论述将滤波理论应用于机载雷达中对单个目标进行距离、速度、方位角和高低角跟踪的多环反馈系统。
In this paper, a filtering theory is applied to the multiple closed-loop feedback system for tracking a single target in range, velocity, azimuth and elevation in an airborne radar.
将高速滑体制成相似的机翼模型,进行风洞试验,即可测定滑坡凌空飞行的空气动力学参数,从而计算大型高速滑坡凌空飞行的空气动力升力、飞行速度和飞行距离等。
If we make a wing model which is similar to sliding mass, we can determine aerodynamic parameters by the wind tunnel testing and thus calculate the lift.
