In this paper the reason of rapid increase of single phase short circuit current in 500 kV substation is analyzed. Through the calculation it is proved that neutral grounding by small reactance is an effective measure to reduce the single phase short circuit current, and the calculation method of the zero\|sequence reactance after autotransformer neutral grounding by small reactance being applied is expounded.

Also the performance of this modified electrode was compared with sodium molybdate modified platinum electrode. The cyclic voltammetry tests show that phosphomolybdic acid modified platinum electrode can increase the catalytic activity for methanol oxidation and it is almost the same as the mono-molybdate (Na2MoO4) modified Pt electrode does. This promote effect mainly comes from the transformation of different valency of molybdenum.

通过循环伏安和计时电流法研究了该修饰电极对甲醇氧化的电催化活性和抗中间产物的毒化作用，并比较了该修饰电极与其单酸盐(Na2MoO4)修饰铂电极的性能，测试结果表明：磷钼酸修饰铂电极能够提高对甲醇氧化反应的催化活性，基本上同其单酸盐Na2MoO4修饰铂电极的催化活性相当，并且这种促进作用主要是由Mo原子价态变化引起的。

The results indicate that the presence of GSH increased the expression of exoY、exoS、phzA1 and gacA,while no difference was observed with others virulence factor genes tested.PAO1 produced markedly less pyocyanin than the wild type strain PAOIP＜0.01Treating with GSH, the PCN production of PAOI(△gshB was increased from 0.47μg/mL to 1.73μg/mL (P＜0.01),the PCN production of PAO1 increased from 1.3μg/mL to 1.9μg/mL(P＜0.05),this result indicates that GSH upregulates PCN production.

The problem is how to consider the relativistic corrections to this potential. Adopting the assummation that the quark interaction is the sum of the usual one-gluon direct exchange and the mixture of linear scalar and vector potentials, we structure the relativistic corrections of order v2/c2to the Cornell potential, including the annihilation potential for the quark and antiquark of the same favors which plays the same role with the one-gluon direct exchange at short distances.
