Although focusing on radar return data for "Echo Tops" and "Merged Reflectivity Composite" maps, these techniques are applicable to any set of planar images.

虽然主要关注“Echo Tops”和“Merged Reflectivity Composite”图的雷达返回数据，但是这些技术适用于任意一组平面图像。

Find a planar point set the distance between two points of a recent algorithm, VS2010 compile.

说明：求一个平面点集最近的两点间距离的算法实现，VS 2010编译通过。

Based on geometry and convex set methods, this paper gives systemically the definitions of global and local convexity for planar closed parametric curve, and proves the two definitions are equivalent.

从几何和凸集的角度，系统地给出了平面闭参数曲线全局凸和局部凸定义，并且证明了这两个定义是等价的。

So what we'll have here is a trigonal planar case, and you can see that we only have three electrons that are set for bonding, so we'll add three hydrogens, and for b h 3, we'll get a stable structure here.

让电子劲量远离的时候，不用考虑它,这个例子是平面三角形，你可以看到，只有3个电子可以成键。

So again, if we think about that shape of that carbon atom, it's going to be trigonal planar, 120° it's going to have bond angles of 120 degrees, because we have this set up of having three hybrid orbitals.

如果我们考虑碳原子的形状，它是平面三角形，键角是，因为我们有这三个杂化轨道。
