Studies on karyotypes wihin clones indicated that all the karyotypes belonged to stebbins ' 3b type. there are different karyotype formulas, polymorphsim of satellite chromosome, variations of chromosomal structure and b - chromosome in clones. chromosomal mutation is important factor of chromosomal structure variations within clones
無性系內核型研究表明：各無性系的核型類型都屬于st吮七us的m型、核型公式不完全川同、隨體染色體具多忐性，染色體存在結構變異，研究認為造成無性系內核型變異的重要原因是染色體突變。 -
In this paper, fuzzy pid controller based on t - s model has been studied. due to lacks of criterion of optimization and excessive tuning parameters, the adaptive genetic algorithm with variable cross and mutation probability is used to optimize the parameters and the performance of control systems is improved. firstly, based on modified pid - flc with four fuzzy rules, scaling factor and the fuzzy consequent parameters are optimized by aga with multiple performance indexes respectively
本文主要研究基於t - s模糊模型構成推理形式的模糊pid控制器，針對以往的模糊pid控制沒有統一的參數整定的準則及大量的待整定參數，本文採用具有動態交叉、變異概率的自適應遺傳演算法（ aga ）優化控制器的待定參數，改善了系統的控制性能。 -
Fourth, the theoretical model of optimum technological growth rate under discrete change is erected. technology is a unique production factor because technological growth experiences a mutation when technological increase accumulates to a certain extent. under this condition, the point - mutation model in tom ’ s mutation theory is applied to explain the phenomenon of technological
將技術作為不同於勞動和資本的特殊生產要素進行考察，即當技術量的積累達到一定程度時，技術增長會產生突變，在此條件下，運用湯姆突變理論中的尖點突變模型，解釋了技術突變現象，討論了勞動和資本的不同組合變化下，在臨界點附近技術突然躍升或下降的突變性質；構建了技術突變完成後的技術增長率優化理論模型。 -
Then, two methods are applied to keep the diversified variety of colony : reserve two special units in new population and increase the mutation factor
針對遺傳演算法的群體多樣性過低的缺點。提出了兩種改進方法，使得群體始終充滿多樣性。 -
The mutation allows for the production of igf - ii, a growth factor that ordinarily comes only from the male genome and is crucial for embryonic development
這項突變讓卵子製造出一般只有雄性基因組才能製造、對胚胎發育非常重要的類胰島素生長因子2 （ igf - ） 。 -
One of them was forecasted to produce transcript factor binding site in intron 6 of silky tyrp1. gel - shift result of this mutation proved that there is transcript factor binding site around the mutated site
經過預測，發現其中的一個snp可能使絲羽烏骨雞的內含子6中出現了新的轉錄因子的結合位點。 -
We are finding evidence that the mutation underlying huntington ' s is double - barreled : it not only encodes an abnormal protein that appears to be toxic to nerve cells, but the faulty protein can no longer prompt production of a key growth factor, starving a particular part of the brain
我們有證據顯示，杭丁頓氏癥突變基因的作用乃是雙管齊下，它不只製造出對神經細胞似乎有毒的不正常蛋白，同時該缺陷蛋白也無法促使某個重要生長因子的生成，造成腦中某個特定部位少了營養物質的滋潤。 -
Correlation of myocyte enhancer factor 2a mutation and the liability to coronary heart disease in patients with metabolic syndrome
