The RF electricity of ice adopts radio frequency technique of the RF dual pole. The frequency can make the water element of the cell which at the certain depth shake at a high speed, it can produce the quantity of heat at 45-60℃ through the quick circumvolved friction. Because the collagen fibre is shrinked, the wrinkle can be tighted. Then the light pyrolysis stimulates collagen and elasticity fibre to become more and arrange once again so as to reach the function of dispelling wrinkle and shrinking pore.
冰电除皱系统采用RF双极射频技术,发射的频率可以在皮下的特定深度内使细胞内的水分子产生高速震动,通过这种高速的旋转摩擦从而产生热量45-60℃,胶原纤维收缩,即刻松弛的皮肤、皱纹被拉紧,随后,真皮层中产生的热效应使胶原增生、重新排列、数量增加,同时修复老化受损的胶原,达到即刻紧肤、长效除皱抗衰老的效果。

For narrow-band signals, three uniform linear arrays, whose grating lobes are not overlapped by setting the angles between the arrays and the same pointing of main-lobes, are used and then multiplication of three patterns is operated to reduce the grating lobes of large-spaced array, which makes the array operate in broad band. For wideband or ultra-wideband signals, array pattern in the whole frequecy band is identical by designing the frequency-dependent weighting coefficients based on the Bessel function, and therefore grating lobes in high frequency parts are suppressed.
对于窄带接收信号,利用三个相交的大间距均匀线阵,通过设置它们之间的角度和主瓣指向相同使各自的栅瓣位置错开,然后把三个方向图相乘从而抑制大间距阵列栅瓣,因而适用于宽频带工作;对于宽带接收信号,利用Bessel函数设计与频率有关的加权系数,产生整个信号带宽内恒定的方向图,从而抑制了高频部分的栅瓣。
