查询词典 buffered

It was found that the highest PAO activities in embryonic axes and radicles of the peanut seedlings occurred in day 4 and day 5 respectively after germination in dark. Additionally, the extraction medium of peanut PAO was 0.1 mol/L phosphate-buffered saline （pH 7.0）, containing 0.5 mol/L NaCl and 1 % polyvinylpyrrolidone.

The results show that:(1) MnO2 deposition on the surface is the main factor resulting in cathode polarization, and the flowing of the solution can remarkably reduce this polarization. Furthermore, the buffered solution can reduce the polarization resulting from H+ concentration difference;(2) it is deduced from the polarization curve that the key factor influencing the performance of MFC is microbial number and metabolic rate and the electron transferring rate from microbial to electrode;(3) the power density arrives at the biggest, 824 mW/m2, when outer resistance is 300 Ω, which is accordance to the inner resistance,(284±18)Ω, deduced from I-V curve;(4) the influences of pH and permanganate concentration on cathode potential is in agreement to Nernst equation.

研究结果显示：(1) MnO2在碳纸表面的沉积是阴极极化的主要原因，而溶液流动可以明显降低极化程度；将高锰酸钾溶解在缓冲溶液中可以进一步降低阴极H+浓差极化；(2)根据极化曲线可以推断，影响电池输出功率的决定性因素应是微生物代谢反应速度和微生物与电极之间的电子传递速率；(3)随外电阻的变化，电池输出功率出现极大值824 mW/m2，相应外电阻为300 Ω左右，这与通过 I-V 关系曲线推导得到的电池内阻(284±18)Ω相吻合；(4) pH值和高锰酸钾浓度对电池阴极电极电势的影响符合Nernst方程。
