解釋
短點頻率-
The engineering bacterium which carried bcih i - chi and i - glu cdna was pcg - ii. two methods of agrobacterium - mediated and gene gun were used to transformate long ya lillium. the results of pcr analysis and southern dot blotting hybridization demonstrated that the chi a nd glu cdna have been intergrated into host genome. at the same time ; compared agrabactenum - mediated method with gene gun method, the transformation frequency of the former was 16. 7 %, while the latter was 50 %, so gene gun transformation method was suitable for long ya liiliwn
用攜帶有幾丁質酶基因和- 1 、 3葡聚糖酶基因的工程菌，通過農桿菌介導法和基因槍轉化法轉化龍牙百合，經pcr和點雜交檢測證明外源基因已經整合到植物染色體中。同時對農桿菌介導法和基因槍法進行比較，發現農桿菌介導法的轉化率為16 . 7 ，基因槍法的轉化率為50 ，因此可能基因槍轉化法更適于龍牙百合的遺傳轉化。 -
Use dot arithmetic of high precision, dots of frequency adjustment are fine
採用高精密度網點演算法，調頻網點細膩精美。 -
Pcr, pcr - southern blot analysis, southern dot blot analysis of lettuce dna confirmed that adw gene had been integrated into the plant genome. the results also showed that the transformation frequency of pb - adw was higher than that of pbg - adw, which suggested that camv35s promoter would be better than pi ii promoter in the case of transgenic lettuce
（ 3 ）細胞核載體pb - adw 、 pbg - adw均採用農桿菌介導法將adw導入萵苣，細胞核轉化獲得了生長良好的抗性萵苣植株，經pcr 、 pcr - southern 、 southern斑點雜交分析證實， adw基因已整合到萵苣基因組中。 -
The changes of electron and nucleus exchange frequency along with external field in the coupled quantum dot, especially with magnetic field and the horizontal electric field has been given
我們還計算了在外加場，特別是垂直磁場和水平磁場作用下，電子交換頻率、核子交換頻率。 -
It indicated that 76. 5 percent of positive frequency of all the plants was achieved by using southern dot hybridization, 87. 5 percent of the plants with gus positive activity was gotten by pcr southern blotting and 42 percent of the plants with gus positive activity was gotten by southern blotting
轉基因卡那黴素抗性植株中， gus表達陽性率為43 ，隨機抽樣的方法進行殺蟲肽和npt基因的pcr檢測陽性率均為100 。經過分子生物學檢測表明， southern斑點雜交76 . 5植株表現陽性。 -
The telemetry delays for each tool have been standardization as channel alphabetical letters. so the telemetry gauge and interface circuit of tools are designed in this paper. the temperature data of the new kind of telemetry tools has special format consisting of an 8 bit digital temperature wore over an 8 frame time period for its high frequency and the data of flowmeter is uplinked on two time dot to determine downhole or uphole rotational direction
本文重新設計了新型遙傳短節和參數測量儀器的介面電路，部分參數的介面電路完全採用硬體電路實現；針對溫度參數的數據頻率高於新型遙傳方式可傳輸頻率范圍的矛盾，提出了按「位」傳輸的新方式；基於流量參數特有的方向性，對流量數據採用了兩道傳輸的方式。
