誘變程序 的英文怎麼說
中文拼音 [yòubiànchéngxù]
誘變程序
英文
mutational procedure-
The experimental procedure that begins with a cloned segment of dna, or a protein sequence, and uses this knowledge to introduce programmed mutations ( through directed mutagenesis ) back into the genome in order to investigate gene and protein function
在已知dna克隆片段或蛋白質序列上引導程序性的變異（通過直接誘變）並返回到基因組，來研究基因和蛋白質功能的實驗方法。Presently most of the theoretical method to predict the propeller - induced hull pressure fluctuation is based on the calculation method in which the pressure is induced by pulsating source in infinite flow. the calculation method is adopted and the corresponded computer program is complied. the propeller - induced hull pressure fluctuation due to blade thickness, blade load, cavity thickness and the change of the cavity volume can be analyzed respectively in the computer program
目前，螺旋槳誘導的船體表面脈動壓力的理論預報方法，大多是以無限流場中點脈動源誘導的周圍流場的脈動壓力的計算方法為基礎的，本文採用該方法編制了計算程序，可以分別考慮槳葉厚度、槳葉負荷、槳葉上空泡厚度及其體積變化在船體表面指定位置上產生的脈動壓力。The main topics in this thesis are as following : presenting details of the microbeam facility, mc 2000, microscope stage, venus - 1 language, modeling on the control program based on the requirements analysis, the control structure and flow chart, the main frame for the integrated program, utilizing acti vex control to implement serial communication between the computer and mc 2000, seamless integration between vb application and matlab, probing into some factors that may influence the controlling precision and providing some methods to solve them
與此同時，對實驗過程中產生的一系列實驗數據進行必要的分析，為進一步進行離子束生物工程中的誘變方向性問題和估計低劑量電離輻射的生物體效應研究提供理論依據。作者承擔了微束裝置計算機控制系統的設計工作，完成了asipp微束裝置計算機控制系統的系統設計、主程序以及樣本架控制模塊的設計；提出並實現了提高裝置通量的相關優化策略等。Through the study of comparative benefit, marginal benefit and management scale benefit of cultivated land, this paper points out that the low marginal benefit of cultivated land is one of the most important economic causes which lead to cultivated land non - agriculture to the government, the enormous temptation of cultivated land non - agriculture lead to less attention paid to the process of it ; while, to the farmer, the random construction of house and the structure of income lead to the less attention paid to the process of cultivated land non - agriculture
本文通過對耕地經營的比較效益、邊際效益和農戶耕地經營的規模效益的深入研究，指出農戶耕地利用效益低下是耕地非農化最重要的經濟原因之一。並且對政府而言，強制徵用耕地過程中所展現的巨大價值誘惑；對農戶而言，建房無序、農戶收入結構的變化，使之對耕地的關注度不斷下降，並導致其對耕地非農化更加漠視，加之在耕地徵用過程中的一次性變現的巨大誘惑，導致無論是政府還是農戶，對待耕地非農化都有所期待。分享友人
