Examples
- Park & powder ? twin ? tip for all fakie tricks : moderate sidecut and enlarged waist width for more stability when landing big air maneuvers
合理的腰部宽度适合做各种的花样动作以及在跳跃落地时稳定性很强。 - Racing - small waist width foe quick edge change : smaller radii slalom shorter skis for carve slalom turns . in giant slalom wider radius longer skis
竞技-竞技回转板的腰部很窄，窄小的腰部在滑行时可以灵活的切换板刃。大回转雪板腰部较宽些，板子也长，在高速滑行中更加的稳定。 - It is shown that the fgb and sgb passing through a paraxial abcd system demonstrate similar irradiance profile at the positions of the equal generalized fresnel number . but the fgb and sgb passing through a paraxial abcd optical system having spherically aberrated lens do not demonstrate similar irradiance profile at the positions of the equal generalized fresnel number . the nearly same irradiance profile at the positions of the equal generalized fresnel number can be achieved if the fgb and sgb have the same a / 2 - factor and waist width
在此基础上首次对相同m ~ 2因子、四川大学博士学位论文不同束腰宽度的平顶高斯光束和超高斯光束作了比较，发现具有棋同矿因子、不同束腰宽度的平顶高斯光束和超高斯光束在近轴abcd光学系统中传输时，在菲涅尔数相同的两个面上具有相侧的光强分布 - By the method of matrix optics , the waist width and imaging distance of gaussian beams through the coupling system are calculated . by the result of the calculation , a set of double planoconvex lens coupling system are designed and manufactured . the coupling efficiency is up to 92 %
利用矩阵光学的方法，计算了高斯光束经耦合系统聚焦后的像距和束腰宽度，以此为指导设计加工了一套双平凸镜耦合系统，耦合效率达92 ；在以上基础上研究了泵浦光与振荡光在激光晶体中的匹配，计算出了泵浦光经耦合系统后的最佳焦点位置。 - ( 2 ) based on the propagation equation of fgbs passing through unapertured paraxial abcd optical systems , the similar transformation conditions are obtained for the first time , which is expressed as that two fgbs with the same beam order have similar intensity distributions at the two positions of equal generalized fresnel number when they propagate through two ajb , cjdi ( i = l , 2 ) systems . furthermore , a comparison between a fob and a sgb of the same beam a ^ - factor but different waist widths is performed for the first time
( 2 )通过对作为整体的平顶高斯光束在无光阑限制近轴abcd光学系统中传输公式的分析，首次得到了平顶高斯光束的相似变换条件，即阶数相同的平顶高斯光束在传输矩阵为a _ ib _ ic _ id _ i ( i = 1 ， 2 )的两个光学系统中传输时，在菲涅尔数相等的两个面上具有相似的光强分布。
