The invention discloses a WEB reverse proxy method, device and system supporting an XSLT file. According to the technical scheme, the conversion work of an XML file and the XSLT file is carried out by a client end, a proxy server only needs to be used for converting an XML page which introduces the XSLT file into an HTML page to be sent to the client end, an original HTML rewriting mechanism is used for modifying an XHTML file which is obtained after converting of the client end, and therefore the proxy server does not need to judge which places in the XSLT file need to be modified. When new modified characteristics of the XSLT file are added, the proxy server does not need to be additionally provided with new codes to maintain an original judging process, the original HTML rewriting mechanism only needs to be maintained, and the maintainability and the expandability of the proxy server are greatly improved.

The technology of this invention is realized by elimination of the original addition of two procedures-pre-quenching and subtemperate quenching after technological refining. By this technology, the metallographic structure of 40 Cr may be changed into mixed metallographic structure of rod-like ferrite and stripe-like martensite; thus fine mechanical properties may be assured. Treatment of 40 Cr by this technology may save about 1.50 yuan per kg than that of original technological refining.

The invention relates to a preparation method for an oxidation catalyst used for purifying diesel exhaust and belongs to the technical field of catalysis. The catalyst has a higher conversion ratio to hydrocarbon and carbon monoxide inside the diesel exhaust, and can be used for oxidizing nitric oxide into nitrogen dioxide. The catalyst takes cordierite honeycomb ceramics or Fe-Cr-Al metallic honeycombs as a base body, takes a titanium, silicon and aluminum composite oxide and a molecular sieve as coating layers, and takes Pt or/and Pd as an active component. The catalyst is divided into two layers adopting use levels of Pt and Pd in varying proportions, so as to adjust the proportion of the nitrogen dioxide in the exhaust. The oxidation catalyst can effectively lower HC and CO of gaseous phases in diesel engine exhaust, can effectively improve the oxygenation efficiency of NO, and has better heat stability.
