从昨天到现在,朋友圈、微博都是关于“山竹”台风的内容。可能是经过去年“天鸽”和前年“莫兰蒂”给珠海和厦门造成的严重损失的教训,今年关于如何减轻台风损失的方法很多,网上疯传的用胶带给玻璃贴“米”字到底有没有实际用处呢?
答案是有的(见下图),而且作用很大。台风天,玻璃破裂常见两种方式,一是被漂浮在空中的杂物撞击导致破裂,二是风撞击玻璃时玻璃震动产生共振效应导致破裂。风在撞击玻璃时,中间区域受到的压力最大,给玻璃贴上“米”,可以分散压力,是最快捷的防止玻璃破裂的方法,也是最经济的方法。如果风力太强大,或是给空中漂浮物撞击,贴“米”也抵御不住,但是可以抑制玻璃破碎后碎片飞溅和分布,达到减少受伤的效果。
知道这个方法后,我昨晚睡前给家里两个阳台的落地玻璃都贴了“米”,由于玻璃面积比较大,又在“米”中间贴了个“口”。当然,如果你家落地玻璃面积很大,你要贴个八卦阵也是极好的,做好防护措施,总比处理灾后受损要轻松。
除了以上给玻璃贴“米”,台风天里个人/家庭还有很多防御工作要做好,比如备好几天的粮食、饮用水,准备一些常见药品、雨衣、满电的充电宝、手机充满电、花费充足,足够的衣物、照明工具(手电、蜡烛)。
我这里逐渐远离了,还好没太大的损失。

沿海一带比较严重,惠东那边损失应该挺大的。
