donor ion 中文意思是什麼

donor ion 解釋
施體離子
  • donor : n. 1. 贈送人，捐款人。2. 【生物學】移植體；【物理學】施主；【化學】給予體，供體；【醫學】供血者，輸血者，（移植術中）皮膚[組織]供給者。3. 【法律】（財產歸屬的）指定權。
  • ion : n. 【物理學】離子。 positive [negative] ion正[負]離子。
  1. A. thalianas were respectively introduced by ion beam with a collection of donor dna having a gradient genetic relation with a. thaliana. in vegetative phase of tl, the ratio of phenotypic variation showed no distinct difference among these transformed populations

    用離子束介導與擬南芥菜親緣關系從近到遠一系列的外源供體的全dna轉化擬南芥菜，在轉化當代營養生長期，各轉化群體的表型變異情況沒有明顯的差別。
  2. But above 700, the resistivity decreases suddenly, as the nb ion diffuse from linbo3 into zno and occupied the interstitial sites. nb ions, as donor doping in zno film,

    Linbo3中的nb擴散到zno中去，占據間隙位置，相當于失主能級，形成電阻率低的n型zno薄膜。
  3. The system we selected is the positive donor ion located in the centers of gaaslgaasal quantum well ( doped density of al is 0. 33 ) in the process of calculation

    在計算過程中，我們選取的體系是0中心的正施主離子處于gaas gaasai （其中以的攙雜濃度為0
  4. In ion beam - mediated total dna transformation, the total dna consisted of all of genetic information in donor, and had multilateral effects on recipient, so there was no common rate of transformation to measure its effect, which meant that it was very difficult to decide an optimum condition of transformation such as influence. implantation experiments showed that the relation between the influence and survival of a. thailand was a saddle curve

    在離子束介導外源全dna轉化中，外源全dna包含有供體的所有遺傳信息，這些外源片段對受體的影響是多方面的，因此轉化效果無法用統一的轉化率來衡量，這就給最佳轉化條件（主要是轉化劑量）的選擇帶來了很大的困難。
