secret-sharing-ideas
针对图像秘密共享前需要像素置乱的问题,基于(t, n)门限多重秘密共享思想,提出一种免置乱的图像秘密共享方案,以第n+1人的秘密份额作为因子参与秘密分割与重构,加大相邻像素之间的差距(Based on (t, n) threshold multiple secret sharing ideas, and put forward a kind of scrambling image from secret sharing scheme to n+ 1 people share the secret as factors involved in secret segmentation and reconstruction, increase the gap between adjacent pixels)

说明: 用于三维空间坐标系变换的7参数模型,在设计坐标系变换的各行业应用中用的最多,从数学角度来说也是最严密的转换方法。
由于结果中最多可求得七个转换参数,即三个平移参数、三个旋转参数(Ex、Ey、Ez)和一个尺度缩放因子(m),因此,通常也被称为七参数法。 (Three-dimensional coordinate system transformation for the 7 parameter model, coordinate system transformation in the design of applications using the most, the industry, from the mathematical point of view, the conversion is the most rigorous methods. Since the results can be obtained up to seven transformation parameters, ie three translation parameters, three rotation parameters (Ex, Ey, Ez) and a zoom scale factor (m), therefore, often referred to as seven-parameter method.)

说明: :建立了碳钢渗硫表面和非渗硫表面的多球凸峰面接触模型,模型中,凸峰高度按高斯函数分布.用塑性流线
理论分析了渗硫层的摩擦系数.计算结果表明:摩擦系数随载荷的增加而增加;相同粗糙度下,磨削加工的摩擦系
数比车削加工的摩擦系数大;摩擦系数随着渗层厚度的增大而增大.从减小摩擦系数的角度来考虑,渗硫层并非
越厚越好.
(the multi-asperity sphere-shape model for surface contact between sulphurized layer and unsulphurized
layer is established.in which the height of sphere-shape asperities follows the Gaussian distribution.1he
frictional coeficients of sulphurized layers are analyzed by using plastic flown line theory.1he results show that
the frictional coeficient increases with the load.the frictional coeficient of ground surface is higher than that
of tumed surface in case of the same roughness.1he thicker the sulphuri[ed layer is.the higher the frictional
coeficient is.From the viewpoint of reducing frictional coeficient,the thickness of sulphurized layer should
be smaller.)
