1、Pph立式止回閥大發(fā)電集團(tuán)的管理要求，這需要我們抓住機(jī)遇，加快技術(shù)進(jìn)步步伐，趕上能源戰(zhàn)略的最后布局。2008年自動(dòng)化市場(chǎng)升級(jí)將達(dá)640億美元面向流程產(chǎn)業(yè)的自動(dòng)化產(chǎn)品及服務(wù)市場(chǎng)隨著對(duì)自動(dòng)化設(shè)備的需求增長(zhǎng)，正在穩(wěn)步發(fā)展。該市場(chǎng)的規(guī)模2003年約為500億美元，未來(lái)5年里有望實(shí)現(xiàn)5.1%的年增長(zhǎng)率，2008年市場(chǎng)規(guī)模將達(dá)到640億美元。美國(guó)調(diào)查公司ARC日前對(duì)面向流程產(chǎn)業(yè)的自動(dòng)化產(chǎn)品及服務(wù)全球市場(chǎng)進(jìn)行了調(diào)查，并公布了上述預(yù)測(cè)。據(jù)報(bào)告，制造業(yè)都在通過(guò)實(shí)時(shí)性能管理，努力提高品牌知名度與企業(yè)的生產(chǎn)效率，智能型現(xiàn)場(chǎng)總線設(shè)備得到了更為廣泛的應(yīng)用。從地區(qū)來(lái)看，中國(guó)仍舊是
