查询词典 affine transformation

The curve, to be calledλ-Bezier curve not only inherits themost properties of n-degree Bezier curve, such as endpoints properties, symmetry,convex hull property, geometric invariability, affine invariance, convex-preservingproperty, variation diminishing property and so on, but also can be adjusted inshape by changing the value ofλwithout changement of control points.

曲线不仅具有n次Bézier曲线的特性：如端点插值、端边相切、凸包性、变差缩减性、保凸性等，而且具有形状的可调性：在控制顶点不变的情况下，随着参数不同，可产生不同逼近控制多边形的曲线。

It has been widely used in recent years, for it not only solves some problems in computer graphics, such as arbitrary topology and compatibility, but also retains several advantages of traditional NURBS, including the properties of localness and affine-invariance.

由于细分曲面不但解决了计算机图形学中遇到的任意拓扑和一致性表示问题，而且还保留了传统NURBS曲面表示所具有的局部性、仿射不变性等良好性质，因而近年来得到广泛的应用。

Analysis result indicated that the exceptional-high concentrations of Mn was found to be the limiting factor for plant growth. The concentrations of Mn, Pb, and Cd in the ten plants and Mn-enrichmentalabilities of the ten plants were analyzed in this paper.Poa pratensts, Gnaphalinm affine, Pteris viltata L., and Phytolacca esculenta Van Houtte were proved to have good metal-enrichmental an...

结果表明，早熟禾、鼠麴草、蕨、和商陆对Mn有较强富集能力，同时也是Mn的耐性植物；早熟禾、鼠麴草以及蕨对Pb的吸收和富集能力较强；小飞蓬、早熟禾和麴草对Cd的富集能力较强；但是各种植物对这 3种重金属的富集能力均未达到超富集植物的要求，进一步的改良栽培实验仍在研究中
