The equations of two classes of 3D polynomial maps that are equivariant with respect to the rotational symmetries of either a regular tetrahedron group or a regular octahedron group are strictly given, on the basis of which the properties of the general Julia sets created by these 3D polynomial maps are discussed and proved.
从理论上分析并证明了三维多项式映射满足等变的条件,精确地给出了关于正四面体群和正八面体群具有旋转不变对称性的两类三维等变映射的具体公式,在此基础上讨论并证明了三维多项式映射的广义Julia集所具有的性质。

His arm is up at footstrike, and he keeps the elbow below the PAS shoulder. He avoids excessive reverse rotation, and naturally "scap loads," rather than forcing the issue.
他的手臂在左脚踏出时正在高点,同时保持手肘低於投球侧肩膀,避开了过度逆向旋转的问题,还能够自然地储备肩膀能量,而不是过度用力。

RS+SLINGER type: The SLINGER is fixed to inner ring, rubber seal is fixed to outer ring. The rubber seal and inner ring can form standard torque contact sealing. This combination of two sealing elements can provide an effective barrier against the entrance of foreign matter, such as mud 、 dust 、 vapour, and the leakage of grease to keep the bearing in good working.
防尘盖与橡胶密封圈组合密封:防尘盖固定在内圈上与内圈一起旋转,橡胶密封圈固定在外圈上,密封胶唇与内圈形成标准扭矩接触密封,这种密封能有效地防止外部泥土、灰尘、水气等异物进入轴承内部,同时能阻止轴承内部的润滑脂外漏,使轴承在恶劣的工作环境下也能保持完美的工作性能。

In classic theory,it is held that, in Sobolev Space [H1]3, there is the upper bound of the norm of the constant rotating flow of the incompressible viscous fluid between two closed surfaces. It is inversely proportional to the viscosity of the fluid, and it will go to infinity when the viscosity goes to zero.
经典理论认为,不可压缩粘性流体定常旋转流在Sobolev空间[H1]3中的范数的上界与流体粘度成反比,随着流体粘度的减小,这一上界会无限地增大。

In summary, we used the following tools during this study: 183 degree fish-eye lens, the rotation tripod which takes the lens as the center of rotation and the self-developed software which can transform the fish eye image to the spherical panorama images. The whole spherical panorama images can then be created seamlessly and conveniently for the real estate usage on the Internet and some case studies are shown in this thesis.
总而言之,使用183度鱼眼广角镜头、以镜头为旋转中心的定位云台和将广角影像转换成球形全景影像的制作软体,就可以方便地将某空间各角度的影像撷取至球形全景影像,完整的制作过程可以变得相当简易及平顺,并且基於本研究所制作的房地产实例也证实了本研究的实用性。

It is shown from this thesis that flow fields on synoptic maps can be decomposed into rotation and deformation fields. Geostrophic non-frictional cyclone and anticyclone vortex patterns are closed circulations around the center point, streamlines of frictional cyclone and anticyclone patterns have spiral forms around the focus point. Saddle fields have four vortex centers (two cyclones and two anticyclones) and a saddle point. Blocking high pressure and cut-off low pressure patterns consist of a vortex center and a saddle point.
本文说明了天气图上的流场可以分解为旋转场和变形场:地转无摩擦的气旋、反气旋的涡旋型式是围绕中心点的闭合环流;考虑摩擦的气旋、反气旋的流型是围绕焦点的螺旋型式;鞍型场有4个涡旋中心点(2个气旋和2个反气旋)与1个鞍点;阻塞高压和切断低压由1个涡旋中心点与1个鞍点组成。
