During coronary sinus ostium pacing, coronary sinus electrodes recorded double potentials, a sharp and high-frequency potential followed by a rounded, low-frequency potential.

冠状窦口起搏时，冠状窦电极记录到双电位，第一个波为高频信号，为冠状窦肌肉结构从其口部向远端激动所产生。

The vib-rotational interaction potentials of He-H2（D2, T2）system were fitted using the Tang-Toennies potential function and nonlinear least square method in a c.m. coordinate system.

运用Tang-Toennies势模型和非线性最小二乘法拟合构造了He与同位素分子H2(D2、T2、)在质心坐标系下的振转相互作用势。

CO〓 oxidation on Pt-Mo and Pt-Ru-Mo electrodes starts at very low potentials c.a.

CO〓在Pt-Mo和Pt-Ru-Mo电极上的氧化起始电位很低，约为0.15V。

The formal potentials in cyclic voltammograms of these 3+ valence complexes are followed: Co〓-TPPS (-0.08V )＞Fe〓TPPS (-0.14V)＞Mn〓-TPPS (-0.23V). The electrochemical reaction of Mn〓-TPPS is reversible, and both of Co〓-TPPS and Fe〓-TPPS are quasi-reversible. The standard heterogeneous rate constants of Co〓-TPPS and Fe〓-TPPS were determined to be 1. 4×10〓cm/s and 1.4×10〓cm/s respectively. The rates of electrode reaction are as followed: Mn〓-TPPS＞Co〓-TPPS＞Fe〓-TPPS, e.i. Mn〓-TPPS is the most easily oxidized by the dissolved oxygen, and Fe〓-TPPS is oxidized slower than Co〓-TPPS. Ni〓-TPPS can not be oxidized. It is considered that oxygen plays an important role in the valence change of central metal atom and the rate of electron transfer in some metalloporphyrins.

三价金属卟啉络合物在循环伏安图上可得到三价到二价的还原和氧化响应，电极电位从大到小排列为：Co〓-TPPS(-0.08V)＞Fe〓-TPPS(-0.14V)＞Mn〓-TPPS(-0.23V)，电极反应可逆性也不相同，Mn〓-TPPS是可逆过程，Co〓-TPPS、Fe〓-TPPS是准可逆过程，实验测得Co〓-TPPS的标准电极反应速率常数ks＝1.4×10〓cm/s，Fe〓-TPPS的ks＝1.4×10〓cm/s，电极反应的速率从大到小为：Mn〓-TPPS＞Co〓-TPPS＞Fe〓-TPPS，即Mn〓-TPPS最容易被溶解氧所氧化，Fe〓-TPPS被氧化的速度最慢，Ni〓-TMPyP不能被氧化，因此我们认为溶解氧对金属卟啉中心离子的价态和电子转移速率起着重要作用。

Greater than -20 mV and decays with time constants ranging from 50 to 110 ms. Inactivation is removed over a very broad range of holding potentials h.p.

N电流在-20mV强除极化中被激化，以衰退常数50-110 ms衰退，并在-40至-110mV被抑止。

为什么呢？因为我的班主任说我严重的违反了校规，于是让我停课三天。

Many of them believe that the conversion of thousands of working-class folk in England spared that nation from the mass carnage and the tyranny that came with the revolution in France.

他们之中有许多人相信，在英国数以千计的劳工阶级之悔改信主使英国免於遭受如法国大革命所造成的大屠杀和专制暴政。
