excess electron 中文意思是什麼
excess electron
解釋
多餘電子-
Fundamental of laser 40ar / 39ar dating method : our laboratory has successfully set up the laser microprobe 40ar / 39ar geological dating method. our works include adjustment of the high - gain electron multiplier in mass spectrometer and correction of mass discrimination, adjustment of the laser, test for absorption ability of minerals to laser, designing and manufacturing high - vacuum sample chamber, sample preparation and irradiation, research on the variability of j values on the surface of rock chips, measuring atmospheric argon, determination and correction of blanks and ages, etc. the laser microprobe technique is particularly effective for some geological samples. it can be used, for example, for research of distribution of the components in extremely small samples that are very difficult to be separated and purified and those which contain excess argon
本文首先從常規~ （ 40 ） ar ~ （ 39 ） ar階段升溫定年實驗室的改進入手，進而建立了激光~ （ 40 ） ar ~ （ 39 ） ar定年實驗室，利用這兩種先進同位素地質定年方法，結合其他手段，對青藏高原腹地和北緣的阿爾金斷裂系多期地質事件進行了詳細的同位素年代學研究：一、參照國際先進實驗室的流程，對我們的常規~ （ 40 ） ar ~ （ 39 ） ar階段升溫實驗室在樣品的預處理、樣品的照射條件和系統空白測量及校正等方面進行了改進，使之產出的同位素年代數據更可靠並為國際同行所承認。 -
In the case that there is only one island that contains an excess electron, we can get the single charge soliton solution of potential distribution in a finite array from the analytic expression we have got. and we find that in the limit of the junction number our result will naturally reduce to the result in the infinite array approximation
當結鏈中只有一個島上有剩餘電子時，由所得的解析表達式可以得到有限長鏈中電勢分佈的單電荷孤子解，並發現當結的數目趨于無窮大時，這個解將自然過渡到無限長鏈近似下的結果。 -
