Southeast asian urban problem and its causes 東南亞國家的城市一極化現象
At times , a polarization can occur 有時,會發生極化現象。
Regional structure of innovative poles and polarization index comparison in china 我國創新極化現象的區域分布與極化度比較
The microorganism and substrate could be mixed and the energy consumption reduced by using bionic peristaltic method , and the concentration polarization could be lowered during the membrane separation 利用蠕動技術達到了微生物與底物充分混合并減少了能耗,同時減少了膜分離過程中的濃差極化現象的產生。
Abstract : the paper interprets alternant polarization phenomen on of even alternant hydrocarbons by discussing charge density on every position of even alternate when it is polarized using perturbational molecular orbitals ( pmo ) 文摘:本文用微擾分子軌道法( pmo )討論了偶交替烴被極化時各位置上的電荷密度,解釋了偶交替烴電荷的交替極化現象。
Using practical data , the authors have given the method and results of quantitative estimation for the influence extent of polarization in the process of electric extraction as well as the consideration for seeking out the way of elimination polarization influence 摘要用測定資料對極化現象在電提取過程中的影響程度給出定量的估計方法,以及在尋找消除極化影響途徑方面所作的考慮和試驗。
To shorten charging time and improve charging efficiency , the circuit can change the charging electric current automatically according to real time voltage of the battery , and dispel the polarization phenomenon by narrowing pulse discharge in the whole course 該電路可根據蓄電池端電壓自動改變充電電流大小,并通過全程窄脈沖放電消除了充電過程中的極化現象,縮短了充電時間,提高了充電效率。
When molecules are solvated in the solution , the solute molecule polarize solvent molecules around it and this gives rise to a field reaction field acting back - ob - the molecule , which will have effects on the structure of solvated molecules and their optical properties 當分子溶解在溶劑中時,溶質分子將使溶劑發生極化現象,被極化的溶劑反過來又會產生一個反應場作用于溶質分子,從而影響溶質分子的幾何結構和光學特性。
In fact , information technology will make the economic test more intense all over the world . “ management actions are to be gathered towards high level and production to be proliferated to low level . ” the polarization phenomenon of cities will become intensified and the scale of big cities will enlarge 實際上信息技術使全球經濟競爭更加激烈, “管理的高層次集聚,生產的低層次擴散” ,城市極化現象加劇,大城市規模將會更加巨大。
By the analysis of the mechanism of charge carries transporting in the detector and the polarization effect of msm detector , we get : the polarization effect of cdse detectors is mainly caused by the poor transporting of charge carries ; to avoid the polarzation effect and improve the charge carries transporting property , the detector must has a suitable anode , so as to make a more suitable electrical field 此外,本文還通過分析探測器中的電荷輸運機理,對具有msm結構的探測器的極化現象進行了定性的分析,指出光生載流子輸運受阻是引起極化現象的原因之一,只有改變探測器的正極接觸,從而改變探測器內的電場分布,改善載流子的輸運特性,才能消除極化現象。
