作者曾于1955年向有关单位提出建议采用橡胶瓶含沙采样器以克服一般瓶式采样器所普遍存在的“突然进注”而严重影响取样成果的问题。该项建议在数年来均未获得重视和试验。近年以来各方面已逐渐感到横式采样器受脉动影响过大,急需给以淘汰,复又苦于瓶式还存在着严重的“突然进注”问题,水文测验规范亦不能不规定瓶式采样器仅可应用在水深不大
In 1955, the author made recommendations to the relevant agencies to adopt rubber bottle sand sampler to overcome the problem of “sudden injection” which is common in general bottle samplers and seriously affect the sampling results. This proposal has not gained much attention and experimentation for several years. In recent years, all aspects of the horizontal sampler have gradually felt the impact of pulsation is too large, the urgent need to be eliminated, complex and suffer from the bottle there is a serious “sudden infusion” problem, hydrological test norms can not provide bottle-type sampler Can only be used in deep water
