试验在黄砂、海泥和不投附着基三种状态下,观察了青蛤幼虫在变态时期的附着量和成活率的变化,以及附着后稚贝的生长与成活情况。结果表明:海泥是青蛤工厂化育苗最适宜的附着基,然后在此基础上进行了不同厚度海泥对不同大小稚贝生长的影... 试验在黄砂、海泥和不投附着基三种状态下,观察了青蛤幼虫在变态时期的附着量和成活率的变化,以及附着后稚贝的生长与成活情况。结果表明:海泥是青蛤工厂化育苗最适宜的附着基,然后在此基础上进行了不同厚度海泥对不同大小稚贝生长的影响试验。试验结果显示:不同厚度的海泥对稚贝生长的影响不明显。我们认为在生产中应选用1mm厚度的海泥做为青蛤育苗的附着基是最适宜的。 展开更多

Starting from the short story "The Parrot and Descartes" by Pauline Melville, we argue that Cartesianism has influenced a view on education which tends to consider good and valuable what is "scientific", "objective" and "universal". The subjective and the local seem to be considered undesirable and unreliable. Brazilian scholars on the education field, such as Coracini and Souza are important support for our argument. 展开更多
