据报道,南京卫生器具厂经过数百次试验,于1988年研制出被专家誉为“滴水不漏型”的凹板球式封水器,使长期未能得到解决的抽水马桶漏水问题得以解决。然而,令人不解的是,尽管该产品价格便宜,安装方便,有关领导和部门在试用后赞不绝口,可就是至今也未能推广。 It is reported that Nanjing Sanitary Ware Factory after hundreds of tests, in 1988 developed by experts as a “drip leak-free” intaglio ball sealing device, the long-failed to solve the problem of water closet to be solved. However, what is puzzling is that although the product is cheap and easy to install, the relevant leaders and departments have not given their full promises after the trial. That is, they have so far failed to promote it.
