文章首先指出氨能杀灭血吸虫卵。农民常用的肥料硫酸(钅亚),可以与消石灰作用生成氨,因而想到用这种方法来增加氨在粪缸中的浓度,以加速血吸虫卵的死亡。该所在1954年7—10月作了五次实验室试验。先将血吸虫病病人的新鲜粪便各200克分装于六个玻璃缸中,各缸再加入400毫升尿和800毫升水;然后按粪尿水的总量分别加入不等量的硫酸(钅亚),其量由1号缸的0.5%递减到15号缸的0.1%,并分别按硫酸(钅亚)量的1/2强来加入消石灰:6号
The article first pointed out that ammonia can kill schistosome eggs. Sulfuric acid, a fertilizer commonly used by farmer farmers, can generate ammonia with the action of hydrated lime. Therefore, this method is envisaged to increase the concentration of ammonia in the excrement tank to accelerate the death of the schistosome eggs. The institute conducted five laboratory tests in July-October 1954. The first schistosomiasis patient’s fresh manure 200 grams each packed in six glass tanks, each cylinder and then add 400 ml of urine and 800 ml of water; and then by the total amount of excrement were added to the amount of sulfuric acid ), The amount of which was reduced from 0.5% of cylinder No. 1 to 0.1% of cylinder No. 15, and slaked lime was added as one-half of the amount of sulfuric acid
