These problem sets are designed to help students understand the importance of ionic concentration gradients and conduction velocities in axons 作業(yè)的設(shè)計(jì)目的是為了幫助學(xué)生理解離子濃度梯度與傳導(dǎo)速度在軸突中的重要性。
2 . to explore and optimize the experimental conditions , such as ionic concentration and ph value , which markedly influenced the detection system of the lsaw biosensor in liquid phase 2 .探索并優(yōu)化液相中na +濃度、 ph值等多種因素對(duì)漏聲表面波生物傳感器液相檢測(cè)系統(tǒng)的影響。
3 . to explore the effects of the different ionic concentrations and ph values on the detection system of the lsaw biosensor and evaluate the consistency of the two channels corresponding to the outer reaction . 4 3 .探索不同ph值和不同na +離子濃度對(duì)傳感器的影響,探討雙通道傳感器受外界條件影響的一致性及最佳反應(yīng)條件的摸索。
Effect of salt treatment on ionic concentration and osmotic potential of cell sap of leaves 2 . 1 effect of salt treatment on ion concentration of cell sap of leaves 2 . 1 . 1 effect of nacl treatment on ion concentration of cell sap of leaves the concentrations of na and cl in the cell sap of leaves increased rapidly with the increase of naci concentration in medium , but the amounts of ci " were lower than those of na + 1nacl處理對(duì)堿蓬幼苗葉片細(xì)胞汁液離子濃度的影響堿蓬幼苗葉片細(xì)胞汁液的na ~ +和cl ~ -濃度都隨著nacl處理濃度的增大迅速增加,但cl ~ -增加量低于na ~ + 。這些結(jié)果說(shuō)明堿蓬幼苗可積聚na ~ + ,作為滲透調(diào)節(jié)劑。
