| 1 | ANALYSIS OF THE MUTUAL INFORMATION BETWEEN INPUT AND OUTPUT OF A CLASS OF CLOCK-CONTROLLED SEQUENCES显示文摘In this paper, the mutual information between clock-controlled input and output sequences is discussed. It is proved that the mutual information is a strictly monotone increasing function of the length of output sequence, and its divergent rate is gaven. | Fan Xiubin Li Shiqu(Department of Information Researches, Zhengzhou Information Engineering Institute, Zhengzhou 450002) | 2000 | Journal of Electronics(China)2000，17，2： | 3 |
| 2 | Walsh Spectrum Properties of Rotation Symmetric Boolean Function显示文摘Rotation symmetric function was presented by Pieprzyk. The algebraic configuration of rotation symmetric(RotS) function is special. For a RotS n variables function f(x1,x2,…,xn) we have f(ρkn(x1,x2,…xn))=f(x1,x2,…,xn) for k=0,1,…,n-1. In this paper, useing probability method we find that when the parameters of RotS function is under circular translation of indices, its walsh spectrum is invariant. And we prove the result is both sufficient and necessary. | WANG Yongjuan HAN Wenbao LI Shiqu | 2006 | Wuhan University Journal of Natural Sciences2006，11，6： | 1 |

| 4 | Exploration of the oxygen transport behavior in non-precious metal catalyst-based cathode catalyst layer for proton exchange membrane fuel cells显示文摘High cost has undoubtedly become the biggest obstacle to the commercialization of proton exchange membrane fuel cells(PEMFCs),in which Pt-based catalysts employed in the cathodic catalyst layer(CCL)account for the major portion of the cost.Although nonprecious metal catalysts(NPMCs)show appreciable activity and stability in the oxygen reduction reaction(ORR),the performance of fuel cells based on NPMCs remains unsatisfactory compared to those using Pt-based CCL.Therefore,most studies on NPMC-based fuel cells focus on developing highly active catalysts rather than facilitating oxygen transport.In this work,the oxygen transport behavior in CCLs based on highly active Fe-N-C catalysts is comprehensively explored through the elaborate design of two types of membrane electrode structures,one containing low-Pt-based CCL and NPMCbased dummy catalyst layer(DCL)and the other containing only the NPMC-based CCL.Using Zn-N-C based DCLs of different thickness,the bulk oxygen transport resistance at the unit thickness in NPMC-based CCL was quantified via the limiting current method combined with linear fitting analysis.Then,the local and bulk resistances in NPMC-based CCLs were quantified via the limiting current method and scanning electron microscopy,respectively.Results show that the ratios of local and bulk oxygen transport resistances in NPMCbased CCL are 80%and 20%,respectively,and that an enhancement of local oxygen transport is critical to greatly improve the performance of NPMC-based PEMFCs.Furthermore,the activity of active sites per unit in NPMCbased CCLs was determined to be lower than that in the Pt-based CCL,thus explaining worse cell performance of NPMC-based membrane electrode assemblys(MEAs).It is believed that the development of NPMC-based PEMFCs should proceed not only through the design of catalysts with higher activity but also through the improvement of oxygen transport in the CCL. | Shiqu CHEN Silei XIANG Zehao TAN Huiyuan LI Xiaohui YAN Jiewei YIN Shuiyun SHEN Junliang ZHANG | 2023 | Frontiers in Energy2023，17，1： | 0 |
