基于计算机视觉与敲击振动融合技术检测鸭蛋壳强度（Duck Egg’s Shell Intensity Model Based on Fusion of Computer Vision and Impact Excitation）
鸭蛋 蛋壳强度 多传感器融合 数据关联
2009/9/11
通过对敲击振动特征频率矩阵变异系数和测定有裂纹蛋壳强度的探索性分析，获得鸭蛋壳强度特征频率的分离阈值λ=0.02。通过传感器数据关联，确定了进入模型的特征变量。采用后向消去法进行多元线性回归建立了无裂纹鸭蛋壳强度预测模型，结合蛋壳强度分离阈值得出基于特征层多传感器融合鸭蛋壳强度的系统模型。验证性试验表明该模型有较好适应性，对于各种颜色、形态鸭蛋的蛋壳强度都有较好的预测效果，误差均值小于3.1%，误...

2010/1/19
An environment-friendly hydrothermal method was used to prepare TiO2@C core–shell composite using TiO2 as core and sucrose as carbon source. TiO2@C served as a support for the immobilization of Ag by ...
Projected SD-pair shell model study for even-even Xe isotopes
projected SD-pair shell model spectrum E2 transition
2009/8/14
Projected SD-pair shell model is used to study the collectivity of low-lying state for even-even Xe isotopes. It is found that the collectivity can be reproduced in term of a three-parameter Hamiltoni...
