摘要：Using certain models of twistor surfaces for fields of force and the mathematical relationships that lie among fields, lines, surfaces and flows of energy, it has been designed and developed a flight electromagnetic type system based on the synergic study of their electromagnetic field geodesics to generate vehicle levitation, suspension and movement without being in contact with the surface. The idea of such work is to obtain a new flight and impulse patent of an electromagnetic vehicle by principles of super-conduction and some laws of the current like Eddy currents and principles which are very similar to mechanics of sidereal objects like galaxies or stars under models of twistor surfaces. This vehicle will be controlled by one microchip that will be programmed by conscience operators algebra of electromagnetic type that leads to the flow of Eddy currents, the iso-rotations and suspension of the special geometrical characteristics vehicle, generating also on the vehicle structure certain “magnetic conscience” that provokes all movements like succeeding to the sidereal objects in the universe.

摘要：以单极子、偶极子和四极子声源为例,研究了在包围声源的四面体等腰三角形测量面上采用等腰三角形扫描路径应用扫描声强法测量声功率的收敛特性,并以扫描声强测量误差为目标函数,以等腰三角形扫描测量面的大小、测量面到声源的距离和扫描线密度为设计变量,应用遗传算法进行了优化.依此优化方法确定测量面的各几何参数,保证了测量精度,提高了测量效率,为快速准确地测量声功率提供了依据.Abstract：To measure the measuring surfaces of isosceles triangle from tetrahedron which surround sound source by the method of isosceles triangle path scanning, the monopole source, dipole source and quadrupole source are taken as examples. The scanning sound intensity method can get the convergent feature of sound power. The convergent feature is studied. The error analysis of scanning sound intensity as objective function, the design variable which made up of the sizeof scanning measuring surfaces of isosceles triangle, the distance between measuring surface and sound source, and the density of scanning line, all of which optimized by GA. This optimization determines the geometry parameters of measuring surface, ensures the measuring accuracy, also improves the measuring efficiency . They lays a solid foundation for swiftly and accurately measuring sound power of sound source.

摘要：很多人都想做出出色的三维CG模型，但是却苦于那些专业三维软件，如3dsmax,maya的复杂！如果你是一名雕塑家，早已习惯了用传统的造型方法，那么Z-brush绝对是你三维CG的首选。Maya用户大概都知道,Maya有一种比较独特的建模方式--SculptsurfacesTool(雕塑表面工具).其实就是利用一支笔刷在模型上涂抹.根据笔刷的影响区域和边界模糊情况在模型(如球体)上进行pull(表面凸起)或push(表面消减)操作,类似于泥塑的过程.这种方式为充满想象力的艺术家提供了有效的建模途径。Z-brush提供了类似的建模方式,并且发扬光大,优化了各个流程,让建模变成艺术雕塑,让雕塑艺术家成为建模艺术家。（其实Z-brush很好的将2维绘图,3维建模,2.5维纹理材质结合了起来）
