【摘要】 本实验采用水力学和生物学相结合的方法，在配有循环水的玻璃水槽中，首次测定出不同螺龄钉螺的起动流速和钉螺吸附在泥土上、铁板上和玻璃上的起动流通，为判断水下钉螺的起动，提供了参考依据。更多还原

【Abstract】 With the combination of hydraulics and biological knowledge, the initial movement of Oncomelania snail was observed in a glass tank with cycling water. Through the experiment,the threshold velocity of snails at different ages,and sticking on different materials such as soil, iron plate and glass was determined, which provides reference for judging the initial movement of the snails in water.更多还原
