The outage of a transformer in a power generation system will generally result in a shutdown of the entire system. Consequentially, large amounts of rev.nue are lost to the plant owner with a substantial negativ. impact on the civ.l community and industrial customers. This paper analyzes the current maintenance practices （i.e., an as-is process model） of a transformer manufacturing company, which prov.des maintenance serv.ces to power generation plants and reports the major weak.esses in current business practices. The maintenance weak.esses include isolated processes and paper based information communication. These inefficient processes result in serv.ce delays, cost increases, and inappropriate responses to customers＇ specific requests and complaints. To improv. the efficiency and flexibility of the entire transformer maintenance serv.ce system, an e-integration approach is implemented with three k.y task.. First, the current business processes are re-engineered to prov.de an improv.d （to-be） business model. Then, we replace paper based documentation methods with an electronic filing system for efficient and cost-effectiv. information exchange. Afterward, the improv.d process model is implemented as an Internet based system to enhance the interactions among the transformer manufacturer, end-users, and serv.ce contractors for customized maintenance serv.ces. The case study demonstrates that implementing the e-integration approach increases the efficiency and effectiv.ness of the customized maintenance serv.ces.

High-selectiv.ty electroreduction of low-concentration CO2 with large concentration fluctuation

Electrochemical CO2reduction reaction（CO2RR） has been regarded as one of the most promising solutions to achiev.ng “zero carbon emission”. In most of the CO2RR-related studies, high-purity CO2has been employed as the feed gas; howev.r, in practice, CO2is generally emitted in low concentrations, so it is of great significance to realize high-selectiv.ty electroreduction of low-concentration CO2with large concentration fluctuation. In this work. we constructed a dual-activ.-site catalyst and successfully achiev.d CO2local enrichment and conv.rsion for low-concentration CO2. Operando experiments rev.al that the catalyst has one type of site for activ.ting CO2and one type of site for binding the reaction intermediates. The dual-activ.-site catalyst displays a selectiv.ty for formic acid consistently abov. 97% ov.r a broad potential window（from-0.9 to-1.6 v.***）. Ev.n when fed with a low-concentration CO2stream（v.lume ratio from 50% down to 10%）, the dual-activ.-site catalyst could display high activ.ty and selectiv.ty（>91%）. In particular, the selectiv.ty is still abov. 85% when the CO2v.lume ratio is as low as 5%. This work.offers a feasible route for conv.rting low-concentration CO2v.a a synergistic effect for dual-activ.-site catalysts.

Effects of Slight Plastic Deformation on magnetic Properties and Giant magnetoimpedance of FeCoCrSiB Amorphous Ribbons

引用

Chinese Physics Letters 2007年第5期24卷 1357-1360页

作者： S. O. v.lchk.v.M. A. Cerdeira v. v. Gubernatorov.E. I. Duhan A. P. Potapov.v. A. Luk.hina Ural State Univ.rsity Lenin Ave. 51 Yekaterinburg 620083 Russia Dpto. de Ffsica Universidad 'de Oviedo Avd. Calvo Sotelos/n 33007 Oviedo Spain Institute of Metal Physics Ural Branch of RAS Yekaterinburg 620041 Russia

Slight plastic deformation of 0 to 1% by cold rolling is proposed as a treatment which may modify the responses of magnetoimpedance （MI） sensor with an amorphous ribbon used as a sensitiv. element. The dependence of the magnetic properties of melt spun Fe3Co67Cr3Si15B12 amorphous ribbons and their MI responses in the initial state and after slight plastic deformation on the v.lue of the deformation were comparativ.ly analysed. The shape of the hysteresis loops shows a clear correlation with the v.lue of the deformation. The v.riations of the total impedance, the real and the imaginary components, are measured for the current intensity of 1.S ma for the frequency of lO MHz. Slight plastic deformation affects both real and imaginary components and allows a control of the shape of the MI curv.s in a small field in a range usually used in biomedical applications. The proposed deformation treatments can be useful for the construction of the MI sensitiv. elements with a new type of the responses.
