Develops a new type of swirling cold air diffuser and tests its performance in aspects of aerodynamics , cold air supply and noise 摘要研制了一種旋流式低溫送風(fēng)口,并進行了空氣動力學(xué)、低溫送風(fēng)及噪聲測試。
We are a major korea ' s aquaculture supplier , specialize in supplying a variety of aquaculture and fish farm products such as larval diets , fish feed , feed supplements , fish medicine , fish farm equipment , air pump , chiller , skimmer , probiotic , air diffuser , live fish etc 我公司是韓國主要水產(chǎn)設(shè)備生產(chǎn)商,特別是提供水產(chǎn)設(shè)備和漁業(yè)農(nóng)業(yè)產(chǎn)品例如幼蟲食物,魚食,喂食設(shè)備,漁業(yè)設(shè)備,空氣泵,冷凍設(shè)備,撇去浮物的器具,噴霧器,活魚等。
In this paper , mapinfo profession 6 . 0 was applied to build and manage space geographical information ; mapinfo mapx4 . 5 was used as a activex control to model and describe the air diffusing area of the spilled gas chemical , by the technology of ole , made used of the integrating environment of visual basic 6 . 0 , we finished developing research on the air diffusion system of spilled gas chemicals based on gis . the system can dynamically show the diffusion range of spilled gas chemicals on computer screen after inputting necessary parameters . the paper include 7 chapters 我們是以mapinfoprofession6 . 0作為空間地理信息建立和管理工具, visualbasic6 . 0作為系統(tǒng)用戶界面開發(fā)與計算模塊編程工具, access2000作為有關(guān)數(shù)據(jù)庫開發(fā)與管理工具, mapinfomapx4 . 5地理信息系統(tǒng)地圖控件作為計算機模擬顯示控件,通過ole技術(shù),在vb的集成環(huán)境下進行“基于gis的水運氣體化學(xué)晶泄漏大氣擴散模擬系統(tǒng)”的開發(fā)創(chuàng)建。
In order to rapidly and effectively predicting the air diffusing area of the spilled gas chemical , and giving corresponding emergency decisions , we make a research on the air diffusion system of spilled gas chemicals based on gis . we hope our study can give a little reference for the controlling of shipping chemicals " polluting accidents 為了能在水運氣體化學(xué)品泄漏事故發(fā)生后,及時、迅速、有效、直觀地對水運氣體化學(xué)品惡性泄漏事故大氣擴散過程做出準(zhǔn)確的預(yù)測并以此為依據(jù)制定相應(yīng)的應(yīng)急措施,我們著手“基于gis的水運氣體化學(xué)品泄漏大氣擴散模擬系統(tǒng)”的開發(fā)研究。
