EffectofUVTreatmentonEarlyDevelopmentofSeaUrchinEmbryos
Objective:To test the effects of UV radiation at 254nm on Sea Urchin embryo development after radiation at the 2-cell stage.Background:Sea Urchins exhibit radial holoblastic cleavage. The first and second cleavages are perpendicular to one anotherand go through the animal and vegetal poles. The subsequent cleavages separate the cells into mesomeres,macromeres, and micromeres. Sea Urchins undergo formation of the blas......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
