random mutation 中文意思是什麼

random mutation 解釋
隨機突變
  • random : n 〈罕用語〉胡亂行為，偶然的[隨便的]行動[過程]。adj 1 任意的，胡亂的，隨便的；（話等）信口亂說的...
  • mutation : n. 1. 變化,變異,更換；【生物學】突變；突變種；【語言學】母音變化；【音樂】（提琴的）變換把位；變聲；【法律】讓受。2. （人世的）浮沉,盛衰。
  1. Neutral mutation - - evolution at the molecular level is primarily determined by mutational input and random genetic drift, rather than by natural selection

    天然突變- -演化過程中在分子的層次上主要是經由隨機的基因流而決定，並非藉由天擇所影響。
  2. Adaptive mutation algorithm has been adopted to ensure the global random searching speciality for feasible individual

    而對可行個體，則採用自適應變異演算法，以保證演算法的全局性隨機搜索特性。
  3. Merging the parents dna, and then applying a random mutation to the merged dna simulates procreation

    合併雙親的dna ，對合併后的dna應用隨機變異以模擬繁衍。
  4. The rest mutations in pp38 and pp24 are at random. sequence analysis also shows the first 195 nuclear acids of pp38 and pp24 are the same except for the 81 site ( g / c ), but this mutation does not cause the change of amino acid. we regard this as a genetic marker connecting with geography in the evolution of mdv but not related to isolated time and pathotype of different strain of mdv i

    對pp24基因和pp38基因進行同源性比較分析的結果表明，絕大多數毒株二者的前195個核苷酸完全一致，不同毒株間的第81位核苷酸的差異（ g / c ）並不引起編碼的氨基酸變化，僅僅與地域分佈有關，這很可能是mdv在長期病毒衍化過程中形成的地域性遺傳標志，而與病毒的分離年代及mdv的致病型等因素無關。
  5. Any random mutation in an intron that proved beneficial to the host organism would have been retained by natural selection

    插入子內任何偶然的突變，只要對宿主有利，就會在天擇的篩選下保留。
  6. Finally, the variant line tc243 - 2, was analyzed by rapd - pcr amplification with 100 random primers. the results suggested that phenotypic variation came from exogenous dna transformation rather than exogenous pollen contamination. a mutation corre

    用100條隨機引物對tc243一株系的rapd一pcr擴增結果表明該株系的變異不是來自外源花粉的污染，同時發現了特異條帶5270 _ 1600對應的變異在tz一ts代能連續穩定遺傳。
  7. In the thesis, the key technical problems utilizing genetic algorithm and random method to design any - cast routing algorithms are explored. we designed and realized the any - cast routing algorithm based on genetic algorithm. resolved the problems concerned in the algorithms, such as the code model, the original genus selection, the fitness function, the crossover strategy, the mutation regulation, and the algorithm ' s convergence, avoidance of dead loop etc. aim at different network scales we propose two any - cast routing algorithms

    論文探討利用遺傳演算法和隨機方法研究選播路由演算法的關鍵技術問題，設計實現了基於遺傳演算法的選播路由演算法，解決了演算法中的編碼模式、初始種群選擇、適應度函數、交叉策略、變異規則，以及演算法的收斂、路由死循環的避免和負載均衡等問題。
  8. Still more frightening, they would by either design or random mutation develop the ability to communicate with one another

    更可怕的是，它們可能經由計畫或隨機突變而發展出相互溝通的能力。
  9. Eventually another random mutation to a cancer gene knocks down another obstacle, initiating another burst of growth

    直到有另一個癌癥基因產生隨機突變，去除了另一個阻礙，而引發另一波的生長。
  10. It evolves in two ways : gradually through random mutation, and more rapidly as different strains of influenza swap genes inside a single animal or person [ see box on opposite page ]

    病毒可經由兩條演化途徑得到在人類間散播的能力：隨機突變而逐漸適應，更快的是在同一隻動物或人體內與其他流感病毒交換基因（參見右頁全球流感病毒株的衍生途徑） 。
