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......閱讀全文

基質效應（matrix－effect）
化學分析中，基質指的是樣品中被分析物以外的組分。基質常常對分析物的分析過程有顯著的干擾，并影響分析結果的準確性。例如，溶液的離子強度會對分析物活度系數有影響，這些影響和干擾被稱為基質效應（matrix effect）。什么是基質效應？基質是指的是樣品中被分析物以外的組分。基質常常對分析物的分析過程有
