作者用食盐与硝酸钾制成各种不同比重的漂浮液。浮聚钩虫卵和蛔虫卵。结果证明:在比重较低的1.060漂浮液中,即可查得钩虫卵。比重每增加0.01,虫卵查得数目便增加1倍。比重在1.110-1.350间,查得钩虫卵最多(见图1)。而蛔虫卵仅从比重1.190以上的漂浮液中,查得虫卵数目显著增加。比重1.250的漂浮液较比重1.190漂浮液,查得虫卵数目增加3倍。并证明漂浮液面中央较边绿为多(见图2)。全部实验查得虫卵最多者为比重1.300的漂浮液。故作
The author uses salt and potassium nitrate to make a variety of different proportion of the floating liquid. Floating gather hookworm eggs and roundworm eggs. The results show that: the lower the proportion of 1.060 floating liquid, you can check hookworm eggs. Each increase in the proportion of 0.01, the number of eggs will increase 1 times. The proportion of 1.110-1.350, check hook eggs most (see Figure 1). Ascaris eggs only from the proportion of more than 1.190 in the floating liquid, check the number of eggs increased significantly. The proportion of 1.250 floating liquid than the proportion of 1.190 floating liquid, check the number of eggs increased by 3 times. It is also demonstrated that the center of the floating surface is more than the green edge (see Figure 2). All experiments found that the largest number of eggs for the proportion of 1.300 floating liquid. So pretentious
