TheeffectoflithiumchlorideonLytechinusvariegatesembryos
PurposeThis experiment will study effects of lithium chloride on sea urchin development, forcusing on archenteron formation.IntroductionGastrulation is extensive cell rearrangement where cells undergo dramatic movements and change relative positions. From this ordered movement, layers of cell are created. The cells that will form the endodermal and mesodermal layers, and then organs, are brought inside the embryo, wh......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
