The results show that smaller height of reaction channel can shorten the time which reactants diffuse from channel to reaction surface, longer length of micro-channel can extend residence time of reactants on the catalyst surface, and consequently increase the methane conversion and hydrogen production. The pressure drop between inlet and outlet increases lineally with the increasing of length, while the height influences the pressure drop significantly when the height is less than 0.4 mm. Based on the overall consideration for the methane conversion and resistance characteristic generally, the suitable height of channel should be between 0.4 mm and 0.6 mm.

结果表明：较小的通道高度能够减小反应物在通道中的扩散时间，较长的反应通道长度能够增加反应物与催化剂的接触时间，甲烷转化率和产氢率提高；通道长度线性地影响微通道进出口压降的大小，而在通道高度小于0.4mm时，通道高度显著地影响进出口压降的大小；综合考虑微通道的重整性能和进出口压降等因素，通道高度在0.4~0.6mm之间较为合适。

In addition, this effect was superficial that made the ion-implanted surface smooth and increased its nanohardness, whereas the abrasion resistance of the treated surface to micromotion test was unobvious.

The research results show for low Sn concentrations, for example 1wt%Sn with respect to Ni, the Ni/Sn surface alloy is energetically preferred. We have also used XPS to characterize the catalysts. The quantified Sn and Ni XP spectra for Ni/Sn/SLT catalysts show that Sn preferentially segregates to the surface of the Ni/Sn alloy. We demonstrate that supported Ni/Sn alloy catalyst provides significantly higher reforming reactivity and resistance to deactivation via carbon deposition than supported monometallic Ni catalyst both in steam reforming of CH4 and CO_2 dry reforming.

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.
