On conic optimization, we work over some properties of cone and its dual cone, and solve the relations between special cones (obtuse cone, orthogonal cone, superior and inferior obtuse cones) and their dual cones.Furthermore, sufficient and necessary condition under which they exist are proved detailed .

本文围绕锥规划问题，对锥及其对偶锥的性质进行了研究，解决了一些特殊锥(钝锥、直角锥、优劣钝锥)及其对偶锥之间的关系，并对它们存在的充要条件给予了详细的证明。

Test and analysis show that, the distribution patterns of the tangent veloctiy fields in the big cone area and the small cone area, which are comprised of para-free vortex and para-forced vortex, are basically identical without a change of the radius of the boundary surface; with the increase of the angle of the small cone, the para-free vortex area decreases and the para-forced vortex area increases, and the emulsifiability of the fluid drips increases with the increase of velocity gradient; the tangent velocity increases with the increase of inlet flow, and the maximum tangent velocities of both the big cone area and the small cone area are 4.94 times of the inlet flow; and the maximum tangent velocity increases with the increase of the split ratio and with the radius of the boundary surface not changed.

试验分析表明，大锥段和小锥段切向速度分布规律基本相同，均由准自由涡和准强制涡构成，分界面半径rm没有变化；随着小锥角θ的增加，准自由涡区缩小，准强制涡区扩大，速度梯度增加会加大液滴的乳化程度；随入口流量增加，切向速度增大，经拟合得出大锥段和小锥段的最大切向速度均为入口流量的4.94倍；分流比加大，分界面半径基本不变，最大切向速度增加。

The chapter first studies the closedness, semicontinuity and cone semicontinuity of cone efficient point sets and cone weakly efficient point sets of the perturbed objective sets when both the objective maps and constraint maps are continuous and the constraint cone is semicontinuous.

Nanoparticles encapsulating PPA HCl were prepared using the solid jelly pulverization technique. The size of the PPA HCl - hydrogel nanoparticles was assessed using a LS particle size analyzer and scanning electron microscopy. The rheological properties of suspensions are characterized by Cone and Plate Viscometer. In addition, any drug-polymer interactions were assessed using a differential scanning calorimeter.

A 3D network visualization framework based on Multi-resolution Animated Cone Tree .

2提出并实现了一个基于动态多分辨率Cone tree的3D网络信息可视化模型MACT。

MACT uses an improved cone tree as the metaphor of network topology. Real time traffic between every two directly connected nodes are represented with animated color lines, and the shade of each line's color is determined by the data rate through the line.

MACT用改进的Cone tree作为网络拓扑隐喻，用不同颜色的动态模式变换线，表示任意两个相连节点之间的实时数据流（颜色表示数据流速，模式变换的方向表示数据流向），用始于一个节点的两种颜色的圆柱，表示流入和流出该节点的数据总量。
