查询词典 secondary cell

Closed-system algal toxicity test was applied to evaluate the toxicity of secondary and tertiary propargylic alcohols to Pseudokirchneriella subcapitata. The effects of propargylic alcohols were evaluated by three kinds of response endpoints, i.e., dissolved oxygen production, cell density, algal growth rate.

bstract：本研究以藻类（Pseudokirchneriella subcapitata）利用BOD瓶进行一密闭式系统之毒性试验，使用溶氧变化量，藻细胞的数量变化，以及以藻类细胞密度变化量计算所得的生长率三个终点，评估二级以及三级炔丙基醇类之毒性，藉由Probit模式求出半致死浓度（50% Effect concentration，EC50）。
