That means satellite data can be used to predict epidemics without having to collect any flies on the ground.

这就意味着，可以用卫星数据来预测流行病，因而不需要在地面上采集任何的苍蝇。

I'll build my house on the level – more, I'll build it at the very base of the hill, so that you can live above me and keep a wary eye on the fellow-citizen you mistrust.

我会把房子建在地面上，不，我索性把房子建在山脚下，这样你们可以住在我上面，顺便监督我这个不受信任的罗马公民。

Because groundwork adopting ferroconcrete structure is chosen in advance, drive error of theodolite working on it is very little and can be ignored.

由于地基是事先选好的，多采取钢筋混凝土结构，经纬仪借助于地基环固定在地面上，工作时带动误差非常小，可忽略不计。

This room should be above ground and have the fewest openings to the outside.

这避难室应该在地面上，并有最少的进出口。

It can be laid directly onto the ground, or used over an existing flat surface.

它可以直接敷设于地面上，对现有的平面上使用或。

As the skull rises from the foreface, it makes a stop, divided by a groove, or fluting, between the eyes.

体格灵活，能以合理的速度在粗糙地面上工作。

6KHz. Myotis frater preys on middle-sized insects on the ground in complex circumstances such as forest, and etc.

长尾鼠耳蝠在森林等复杂环境中捕食地面上中等大小的昆虫。

Here, we will give an independent proof of the existence for inequality (2.1.3), and by the way, give an estimate on the width of the bi-enclosing annulus of closed convex curves in the plane. Secondly, in this part, we will introduce the notation of average geodesic curvature for curves in the hyperbolic plane, and investigate the relationship between the embeddedness of the curve and its average geodesic curvature.

其次，对双曲平面上的曲线引入平均测地曲率的概念，并讨论双曲平面上凸曲线的嵌入性与它的平均测地曲率之间的关系，其目的是为了将双曲平(来源：ABC论84文网www.abclunwen.com)面上曲线的性质与欧氏平面中曲线的性质作一些对比；最后，我们利用Minkowski支撑函数构造了一类新的非圆的光滑常宽曲线，其目的是想回答有关常宽曲线的一些未解决问题如是否存在非圆的多项式常宽曲线？

When there is no gravitation , our feet no longer stay on the ground .

如果没有地心吸力，我们的脚就不能再站在地面上了。

When there is no gravitation , our feet no longerstay on the ground .
