目前对吸虫幼虫从螺蛳逸放的模型知道得很少,对血吸虫尾蚴逸出模型也知道得不多。在以前的实验中是用手把螺蛳拿到不同的水容器中逸放尾蚴。作者认为只有通过自动装置的工作才能期望得到更确切的知识。鉴于最初的“羽化钟”使人们能更深入研究昆虫的羽化模型,因此作者为了研究吸虫幼虫从螺蛳宿主逸出的模型设计了一个自动装置。这装置能把每只用线悬挂的螺蛳至少每隔半小时转移到不同的烧杯中逸放尾蚴。这
At present, little is known about the model of the fluke larvae to be released from the snail and little is known about the escape model of the schistosome cercariae. In previous experiments, snails were taken by hand into different water containers for cercariae release. The author believes that only through the work of automatic devices can expect to get more precise knowledge. In view of the fact that the first “clock of emergence” allowed one to study more deeply the insect eclosion model, the authors designed an automatic device to study the model of fluke larvae escaping from snail hosts. This device can be used to every thread hanging snail at least every half an hour transferred to a different beaker to release cercariae. This
