【導(dǎo)讀】通燈運(yùn)行控制的方法。采用組態(tài)軟件實(shí)現(xiàn)監(jiān)控系統(tǒng)的上位機(jī)設(shè)計(jì),在。燈的信號(hào),PLC控制系統(tǒng)和組態(tài)監(jiān)控系統(tǒng)進(jìn)行實(shí)時(shí)數(shù)據(jù)交換。人多、車多道路少的道路交通狀況已經(jīng)很明顯了。技術(shù)和通訊技術(shù)而發(fā)展起來的一種新型工業(yè)控制裝置。近年來PLC的應(yīng)用更為廣泛，數(shù)據(jù)采集、狀態(tài)判別和輸出控制。對(duì)控制對(duì)象的工作過程進(jìn)行全程模擬仿真，實(shí)現(xiàn)遠(yuǎn)程控制。利用了計(jì)算機(jī)和PLC的特點(diǎn)，實(shí)現(xiàn)了優(yōu)勢(shì)互補(bǔ)而得到廣泛應(yīng)用。我們的人身安全。尤其在大城市里，絕容不得有半點(diǎn)失誤。系統(tǒng)啟動(dòng)后，南北方向紅燈亮25S，同時(shí)東西方向綠燈亮20S,兩個(gè)方向的綠燈閃亮間歇時(shí)間均為1S。在眾多的PLC設(shè)備中，我們選用了歐姆龍公司的CPM1A型PLC。首先，歐姆龍公司是世界著名的幾大PC生產(chǎn)一開發(fā)的廠家之一，其產(chǎn)品在用戶中具有很高的聲譽(yù)。而且其屬于整體式的。NTLink與PT之間進(jìn)行高速通信。b.有10點(diǎn)至40點(diǎn)多種CPU單元。由于原有SYSMAC支持軟。件及編程器都可繼續(xù)使用，故而系統(tǒng)的擴(kuò)展及維護(hù)都可簡(jiǎn)單進(jìn)行。包含“MCGS組態(tài)環(huán)境”和“MCGS運(yùn)
【正文】 yntactical structures, speech rhythms, levels of style.” (Wang, 1991:93). （ 2） Poetic art According to Wang, “Bly?s point about the ?marvelous translation? being made possible in the United States only after Whitman, Pound and Williams Carlos Williams posed poetry in speech rhythms shows what may be gained when there is a genuine revolution in poetic art.” (Wang, 1991:93). （ 3） Language “Sometimes language stays static and sometimes language stays active. When language is active, it is beneficial to translation” “This would require this kind of intimate understanding, on the part of the translator, of its genius, its idiosyncrasies, its past and present, what it can do and what it choose not to do.” (Wang, 1991:94). 18 Wang expresses the difficulties of verse translation. Frost?s ment is sufficient to prove the difficulty a translator has to grapple with. Maybe among literary translations, the translation of poems is the most difficult thing. Poems are the crystallization of wisdom. The difficulties of poetic prehension lie not only in lines, but also in structure, such as cadence, rhyme, metre, rhythm, all these conveying information. One point merits our attention. Wang not only talks about the times? poetic art, but also the impact language?s activity has produced on translation. In times when the language is active, translation is prospering. The reform of poetic art has improved the translation quality of poems. For example, around May Fourth Movement, Baihua replaced classical style of writing, so the translation achieved earthshaking success. The relation between the state of language and translation is so
