crossover current 中文意思是什麼
crossover current
解釋
交變電流-
The diurnal constituents at some of the crossover points and all of the semi - diurnal constituents at all of the crossover points as well as 16 tidal gauge data are assimilated in the ocean model, this is because the assimilation of the diurnal constituents at some crossover points make the result worse. the improvement is 36 % for m2, 54 % for s2, 42 % for k, 30 % for 01 compared with the results of dynamic model without assimilation. in the stratified ocean, mixing controls the intensity of the ocean current
為了克服交叉點上全日分潮精度較低的局限，文中主要將半日分潮同化進模式中，而全日分潮只在部分交叉點上進行了同化，同時同化了沿岸16個驗潮站的調和常數，同化高度計資料和沿岸資料后， m _ 2 、 s _ 2 、 k _ 1 、 o _ 1四個主要分潮的結果精度分別提高36 、 48 、 20 、 12 。 -
Simulation results show that cathode over - potential under low current density is considerably increased because of methanol crossover, but its effect becomes much lower under high current density
模型顯示在低放電電流密度下，甲醇穿透顯著地增加了電池陰極過電位，降低了電池電壓；但在高電流密度下，甲醇穿透對電池性能的影響不顯著。 -
A genetic algorithm ( ga ) is developed, including encoding, crossover, and mutation operations, which can smartly use the information such as the permissible switching number, switching time, and current condition of equipment
在計算過程中，可巧妙計入開關動作次數限制，動作時段及開關當前狀態等信息。 -
Model indicates that, at low current density and high methanol concentration, the methanol crossover poses a serious problem for a dmfc
模型計算顯示，在低電流密度和高濃度甲醇進料情況下，甲醇滲透將成為dmfc的一個嚴重問題。 -
The economic benefit as the basic study angle ; then establishes the new urban development, particularly the crossover - type extension development as the basic study object following the investigation on the current urban development in china. afterwards, the paper also analyzes the related theories in china and abroad, and elaborates that the urban development must face square the actuality in china and hold a correct attitude of " homeland standpoint " while absorbing the nutn ' ent from the west. moreover, the paper illustrates the basic theory and analysis approaches employed for the study in this field, i. e. the economic principles and thinking, accentuating the philosophy tendency in such studies, which means the proposal of any scientific method and technological measures must be based on the knowledge of their existence and the original background and with equal attention given to the epistemology and methodology
本文通過對城市發展的經濟成因分析，選取城市綜合效益、特別是經濟效益作為基本研究視角；通過對當代中國城市發展的現實考察，確立城市新區發展、特別是跨越式外延發展作為基本研究對象；通過對國內外相關理論的分析，認識到在汲取西方有關理論營養的同時，必須正視中國實情，端正「本國立場」 ；本文還闡明了開展該領域研究的基礎理論和基本分析方法，即經濟學原理和經濟學思維，強調了開展該領域研究的哲學傾向，即一切科學方法和技術手段的提出必須以對事物的存在及其產生的背景的認識為前提，認識論與方法論不可偏廢。
