impurity concentration 中文意思是什麼

impurity concentration 解釋
雜質濃度
  • impurity : n. 〈常用 pl. 〉1. 不純,不潔。2. 下流,不道德,不貞節,雜質。
  • concentration : n. 1. 集中。2. 【化學】提濃,蒸濃,濃縮;濃度;稠密度;【礦物】汰選,選礦,富化。3. 集中注意,專心。
  1. Some cubic perovskites are good cases in point such as srtio3 and ktao3. experimental results show that when ba2 + and li + are doped into the above materials respectively and at the same time the impurity content is higher than their critical concentration, the impurity induced ferroe lectric phase transition occurs

    Srtio _ 3和ktao _ 3是典型的量子順電體,實驗表明當兩者分別摻雜ba ~ ( 2 + )和li ~ +且雜質濃度超過各自的臨界濃度時,順電相不再穩定,出現由雜質導致的鐵電相變。
  2. From then on, the above two shortcomings had been overcome. impurity concentration and junction depth can be accurately controlled and freely adjusted. both low and high dopant concentration can be gained easily, and ideal distribution of ga in si can also be achieved with uniform surface concentration, good repeatability and high eligibility and excellence ratio, which have greatly improved comprehensive performances of the devices

    此工藝發明以來,克服了上述兩者的弊端,雜質濃度和結深能準確控制而又能任意調整,可進行低、高濃度階段性摻雜,得到元素ga在si中的理想分佈,而且表面濃度均勻一致、重復性好、合格率和優品率高,改善和提高了器件的綜合性能。
  3. Author analyzed the relationship between the length and the impurity concentration of drift region and thickness of buried oxide layer and thickness of soi and the charges of oxide layer and bias voltage of bulk and breakdown voltage and on - resistance by numerical simulation

    採用數值模擬分析方法,深入研究了漂移區長度、漂移區濃度、埋氧層厚度、頂層硅厚度、氧化層電荷以及襯底偏壓對resurf效應、擊穿電壓和導通電阻的影響。
  4. The main contents are as followings : ( 1 ) the rules of choosing characteristic lines of fe and ni elements in the cu - pb alloy are investigated ; ( 2 ) the characteristic line of the impurity element and that of the reference element makes up a line pair. the intensity ratio of the line pair measured as an y - axis and the corresponding concentration ratio as x - axis, calibration curves for composition analysis is fitted at the 4 kinds of buffer gases

    Q )採用內標法,由樣品中雜質元素的分析線和內標元素參考線組成分析線對,對五種不同的鉛黃銅樣品,實驗通過測定了雜質元素分析線隊的強度比,以分析線對的強度比為縱坐標、分析線對所對應元素的含量比為橫坐標,擬合出了一系列在四種緩沖氣體中的定標曲線。
