TheEffectofpHLevelsByVaryingtheAcidityoftheExtracellularSolution
BackgroundZebrafish, Brachydanio rerio, have a distinct embryonic development. The embryo goes through a process called epiboly. Epiboly, as defined in the sixth edition of Developmental Biology(Gilbert 2000), is the movement of epithelial sheets (usually of the ectoderm cells) that spread as a unit, rather than individually, to enclose the deeper layers of the embryo. Epiboly enables an embr......阅读全文

基质效应（matrix－effect）
化学分析中，基质指的是样品中被分析物以外的组分。基质常常对分析物的分析过程有显著的干扰，并影响分析结果的准确性。例如，溶液的离子强度会对分析物活度系数有影响，这些影响和干扰被称为基质效应（matrix effect）。什么是基质效应？基质是指的是样品中被分析物以外的组分。基质常常对分析物的分析过程有
