migration current 中文意思是什麼
migration current
解釋
遷移電流-
But the comprehensive properties were improved remarkably. with the addition of carbon nanotubes, the polarization of charging process decreased, the plateau of discharge became flatter and the migration of potential of peaks value of cyclic voltemmograms reduced. for the other hand, the exchange current increased, ohm resistance and electrochemical reaction resistance of the electrodes decreased, the diffusion resistance of hydrogen and the resistance of adsorption decreased, too
摻入碳納米管對儲氫合金電極的容量影響較小，但其電化學性能卻有較大的改善，主要體現在：充電的極化減小，放電平臺更加平穩、循環伏安曲線的峰值電位隨掃描速度增大的遷移量減小，交換電流密度增大，電極的歐姆電阻、電化學反應、擴散電阻和吸附電阻均減小。 -
Finally, after the long - term ion migration test, we analyzed the relation between the current and accumulative charge with the test time, computed the ion mobility and migration distance, and analyzed the distribution variety of na + and k + in the test samples
對10支試品進行了長期離子遷移試驗，測量了泄漏電流曲線和累計電荷量隨時間變化曲線，計算了試品的離子遷移率和遷移距離，並對試品na ~ + 、 k ~ +的含量進行了化學分析。 -
Then also proceeded the verification to the migration direction of the neuropteris and linopteris at the same time, clarified the research meaning of the current flora finally. firstly, it has certain leading meaning for thorough research the origins of china plants. secondly, provided the new proof again for the migration research of the plants
在此基礎上，作者對中國納繆爾早期植物群整體面貌進行了綜述，指出當前植物群是繼靖遠磁窯靖遠組植物群（李星學等， 1974 、 1987 、 1993 ） 、寧夏植物群（吳秀元等， 1987 ）等之後，西北地區又一個確切的納繆爾早期重要植物群。 -
The following is the current list of occupations in demand for migration purposes
如申請人職業為緊缺職業，但獲得工作- 15分 -
Current representaive policies are in need of special hardware to record history page access infonnation, resu1ted in their poor generality. to overcome this deficiency, we propose an instantaneous information - based dynarnic page migration policy, which does n ' t need any support of hardware. in this policy, we use some instantaneous $ iv n information directly obtained from caches to substitute traditional history information
為了提高策略的通用性，我們設計了一種無需特殊硬體支持的基於即態訪問信息的動態頁遷移策略，在策略的信息收集階段採用直接從cache中獲取的即態訪問信息來代替傳統策略使用的歷史訪問信息，在此基礎上形成頁面動態復制或遷移的策略，從而消除了硬體開銷。 -
This thesis is founded on the investigation of the ion migration of 500kv dc ceramic support insulators for the production of the 500kv dc ceramic support insulators. in the test system, we added the grounding switch for each circuit and the mutual switch, prescribed the four status of the current measuring program, making the measurement system more stabile
在對離子遷移試驗研究的過程中，對原有離子遷移試驗測量系統進行了改進，通過為每路泄漏電流迴路設置接地開關及公共測量開關，並在軟體上為測量迴路設定4種狀態，提高了測量系統的穩定性。 -
Using the 2000 census data this paper estimates the size of the return migrants, describes the socio - economic characteristics of the return migrants and their differences from those of current migrants or non - migrants, and examines individual and household level determinants of return migration
摘要本文利用我國2000年第五次人口普查的數據，估計返遷人口的規模並描述返遷人口的人口社會特徵及其與現在的遷移人口與非遷移常住人口的差異，從個人因素、居住地類型以及家庭戶特徵三個方面分別討論了返遷的決定因素。 -
This system is a totally automatic measuring and analyzing system with wide measuring range ( from 10 - 16 to 10 - 2a ) and high precision ( 0. 2 % ) which is first developed in china. a 50 - loop current measurement and control system, and a micro - current automatically cycling measurement system together with its three - level protecting system are developed in this thesis. additionally, a software package for this measuring system of ion migration test is developed successfully
在對新型絕緣子離子遷移試驗測量系統研製和開發的過程中，本文設計並研製出了50路電流測量控制系統，微電流自動循環測量系統及其三級保護系統；並成功地開發出一套離子遷移試驗測量系統的軟體系統，該軟體系統不但簡潔、易用，而且實現了採用軟體對多個硬體設備的同步、協調控制，以及通過軟體對多個（達100個） i / o節點的實時控制，另外，還實現了測量數據的自動存儲以及對累積電荷量大小和發展趨勢的自動分析功能等。
