一九五○年陝州水文站是用立式採样器採取含沙水样的,工作即不方便,成果也不合理想。后来改用横式採样器,又因彈簧拉力裝置不够恰當,应用時常發生漏水现象,於是我有功夫就拿出採样器来摸索改装,經過同志們的帮助,先后改裝三次,才完成一个用活钩控制槓桿,(?)拉簧關閉蓋子样式。(如图一) In 1950, the Shanzhou Hydrological Station used a vertical sampler to take samples of sandy water, which was inconvenient to work and did not yield satisfactory results. Later switch to horizontal sampler, due to spring tension device is not appropriate enough, the application of water leakage occurs often, so I have time to take out the sampler to explore the conversion, with the help of comrades, has been modified three times before completing a With live hook control lever, (?) Tension spring to close lid style. (Figure 1)
