The concentration of the polymer that can increase the viscosity of the system had nothing with the interfacial tension.

当烷醇酰胺浓度超过0.3%时，界面张力反而升高；部分水解聚丙烯酰胺的浓度对二元体系的界面张力影响很小，它只是增加了体系的黏度。

In the second part of this research, the effect of the addition of ethanol on the micellization of C14TAB was studied also by ITC at temperatures of 15-40℃. The results show that with increasing ethanol concentration the cmc values first reach a minimum at an intermediate ethanol mole fraction xmin and then increase with increasing ethanol mole fraction.

本研究中第二部份为利用恒温滴定热卡计，研究温度范围15℃40℃之C14TAB + ethanol效应，由实验结果发现cmc值会先随著乙醇浓度增加达到最低值，此时的乙醇莫耳分率为xmin，然后cmc值再随著乙醇浓度增加而增加。

While 30μmol·〓 FRCRSFa and 10μmol·〓 E-4031 were dialysed intracellularly via the patch-pipette, FRCRSFa significantly decreased 〓 exchange current and there was no the further decrease after adding FRCRSFa in the perfused solution with the same concentration, whereas E-4031 dialysed had no effect on 〓 exchange current, but a obvious increase of it occurred when adding E-4031 to the perfused solusion with the same concentration.

分别将30μmol·〓的FRCRSFa和10μmol·〓的E-4031加入微电极内液中，FRCRSFa显著抑制了〓交换电流，当在细胞外灌流液中加入同样浓度的FRCRSFa时无进一步抑制；而胞浆内的E-4031对〓交换电流无显著作用，而在灌流液中加入同样浓度的E-4031后，却显著增强了〓交换电流。

Liquid culture medium dilution test was used to study the optimal concentration for intrathoracic and intra - abdominal cavity injection.

结果胸腹腔内注射聚维酮碘抗感染时的最佳抑菌浓度为1000～625mg／L，部分菌在312mg／L有效，实际使用浓度为1500～2000mg／L之间，抑菌、杀菌效果满意可靠。

In this paper, the effects and the regulation mechanism of glucose concentration on SUC2 expression were reviewed and the use of such gene and the invertase in the future and the research trend were predicted.
