查询词典 length of vector

The results are the following: When calculating the motion mass, it is better to use idler's equivalent mass instead of the rotating part mass and serial idler's rotating inertias and equivalent mass are calculated. The accurate analysis result for the deflection curve length of the belt shows: The error calculated by the approximate parabola length is lower than 10〓. Thus the approximate method is accurate enough for calculation. The relations between the running resistances coefficient and the belt velocity are studied by experiment, which are the bases for calculating the linear coefficient values between them.

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。
