As analyzed, ( 1 ) the rapd technique is highly sensitive to investigating genetic diversity in t. lepturus and e. muticus. t. lepturus exhibits lower polymorphism and genetic diversity than e. muticus ; ( 2 ) according to the analysis of the partial mitochondrial 16s rrna gene sequences, a very low intraspecific variation and considerably high divergence among species were found, which reveals a dual nature of conservatism and variability in mitochondrial 16s rrna gene ; ( 3 ) five primers generate the species - speeific rapd sites and these sites can be served as the molecular markers for species identification and ( 4 ) it can be proved at dna variation level that t. lepturus and e. muticus are of two species respectively pertainiag to different genera, which supported the nelson taxonomic conclusion
分析結果表明: （ 1 ） rapd技術研究黃海帶魚和小帶魚的遺傳多樣性具有較高的靈敏度和檢出率，帶魚的多態比例和遺傳多態度均較小帶魚的低; （ 2 ）線粒體165出兇a基因序列在分析兩物種遺傳變異時表現出保守和變異的雙重特性，種內變異極小而種間較大: （ 3 ） 5個隨機引物擴增出種特異的ra衛d帶，可作為種間分子鑒定標記; （ 4 ）研究證實帶魚和小帶魚是不同屬的兩個種，從而在分子水平上支持了nelson分類系統的觀點。 -
In chapter 4, a simulation approach is presented, which combines the outdoor radio propagation model, the eigen - driven patterns of handset diversity antenna with two feed ports and combining schemes of receiving signals, to investigate the performance of a dual antenna handset under co - channel interference ( cci ) and multi - path fading environment
第四章首先用本徵激勵方向圖的概念來產生手機雙埠分集天線的接收信號矢量，然後將其與城市室外電波傳播模型、分集合併方式相結合，建立了分析在具有共道干擾和多徑衰落環境中手機雙天線系統的性能模型。 -
Although the anthropological foundations for aesthetic experimental writing are diverse, they can be summed up as : ( 1 ) anthropology has dual goals, first describing the diverse social and cultural systems found among human species, and then attempting to discover regularities in this bewildering diversity ; ( 2 ) contemporary anthropological aesthetics provides the foundation for new aesthetics ; it is in itself a kind of experimental writing under the control of the cultural situations
摘要美學實驗性寫作的人類學依據是各異的，但可以簡要地概括為： （ 1 ）人類學有一個雙重目標，首先是要描述那些分佈於各個人類種族中間的不同社會文化系統，然後又試圖去探索令人困惑的多樣性下所隱藏著的社會文化模式的規律性； （ 2 ）當代人類學美學為新美學提供了基礎，它本身就是一種受文化情境制約的實驗性寫作。 -
Superficially, dual separation and amalgamation of china rural finance structure and institution is the result of its practicing finance control policy ; essentially, its existence is determined by china rural economic development and its rural financial demand diversity
摘要我國現階段農村金融市場正式與非正式金融的二元分割與共存，從淺層次上來看，是我國實行金融進入管制與利率管制等金融抑制政策的結果；深層次來看，是我國農村現階段的經濟發展水平及農村金融需求主體的多樣性程度所決定的。 -
In the second charper, two reformed metheds has presented, which are competition adaptation - ga based on elitist and dual mutation adaptive - ga which can increase the population diversity and can decrease the dependence of genetic algorithms " result to the control parameter of operators and the status of initial population. to testify their abilities of algorithms, some studies have excuted which included the study to optimize parameter for pid and the study to multivariable intelligent decoupling control for mimo system. the outcomes have showed us that this amendment has a better effective than conventional means and the genetic algorithms which have no change
第二章中，在已有文獻的基礎上，創新性的提出兩種改進演算法：基於最優保留的聯賽競爭機制遺傳演算法（ competitionadaptation - gabasedonelitist ）和雙變異自適應遺傳演算法（ dualmutationadaptive - ga ） ；通過對演算法中選擇運算元和變異運算元的有效改進，提高了演算法的尋優能力和尋優效率，增加了群體中個體模式的多樣性，對于演算法中存在的欺騙問題、早熟問題以及成熟前收斂問題有明顯的改進作用。
