這種混凝土可以顯著降低混凝土施工中的噪音污染；大幅度減輕工人的勞動強度；減少傳統混凝土施工中因漏振或過振造成的麻面或離析；解決了配筋密集、結構復雜部位因振搗不足而造成的質量缺陷問題；同時，由於自密實混凝土在配製中，大量利用粉煤灰、高爐礦渣等工業固體廢棄物，有利於資源的綜合利用和生態環境的保護；從而被譽為「綠色混凝土」 ，是未來混凝土向高性能發展的方向之一。Aiming at the limitation of basic evolution strategies, a kind of growth mechanism - based evolution strategies and its realization are introduced. chapter three presents the evolution strategies - based optimizing of seaport container logistics system, firstly the structure of chromosome is introduced, then a kind of hybrid mutation operation is used, the detail process of the optimizing method is also described, finally the traveling sequence optimization of the containers is introduced as an example to testify the feasibility of the new optimizing method
在以往的港口物流系統規劃研究中，遺傳演算法和模擬退火法是經常採用的數學方法，第三章首次研究了基於生物進化策略的港口集裝箱物流系統優化方法，提出了一種基於混合變異的自然數編碼進化策略演算法和染色體的構造模式，並以集裝箱運送順序優化問題為例，實現了基於生物進化策略的港口集裝箱物流子系統的優化。Laboratory experiments were carried out to analyse the relationship between ionizing radiation and chromosome non - disjunction, and its pathogenesis. in the epidemiological part, patients were collected from october 1999 to december 2002 ( they consulted doctors in shanghai xinhua hospital pediatric hospital of fudan university, henan province genetic institute ), controls were healthy children who were similar to patients at age, gender, born place and so on. patients were diagnosed according to their karyotype [ 47, xy, + 21 or 47, xx, + 21 or 47, xy ( xx ), + 21 / 46, xy ( xx ) ]
本課題第一部分收集了自1999年10月起至2002年12月止的ds病例（就診于上海新華醫院、復旦大學附屬兒科醫院、河南省遺傳所等醫院）以及與病例組在年齡、性別、出生地等一般情況相對應的正常兒童，病例的診斷以染色體核型分析結果為準，患者核型為47 ， xy （ xx ） ， + 21或核型為47 ， xy （ xy ） ， + 21 46 ， xy （ xy ） ，對照組核型為46 ， xy或46 ， xx 。Cells were collected after being passaged 5 times and used to identify infection by rt - pcr, direct fluorescent antibody, sandwich elisa. results indicated that integrated particles of csfv could be obtained from constructed full - length cdna
連續傳代5代以後，收集各w摘要代細胞至第10代，採用rt一pcr 、直接熒光抗體染色和夾心elisa技術進行鑒定，結果均為陽性。The researchers described seen genetic risk factors ? dna sequences present in some people but not others ? bunched in a relatiely small region of one of the human chromosomes, chromosome 8, that reliably predicted one ' s probability of deeloping prostate cancer
研究者們介紹了這七個遺傳風險因子一些人所含有的特殊的dna序列而另外的人卻沒有聚集在人類8號染色體上一個相對較小的區域，而且它們能夠可靠的預測一個人患前列腺癌的可能性。With the quickening paces of industrialization and urbanization, as the spatial carrier where population, economy, technology, information, culture, institution, and so on, are highly agglomerated, the metropolitan is profoundly affected by social and economic activities, and facing a lot of threats about human settlements, such as pollution, traffic, criminals, infectious diseases, especially the problems of safety spaces, which causes more and more attraction to the quality of urban living space
隨著我國工業化與城市化進程的不斷加快，城市作為人口、經濟、技術、信息、文化、制度等社會經濟要素高度集聚、受到人類社會經濟活動深刻影響的空間載體，環境污染、交通擁擠、城市犯罪、傳染性疾病易發多發性等人居環境問題，尤其是居民生活安全問題越來越突出，促使人們對城市生活空間質量越來越關注。So that combine the genetic algorithms and neural network to complete the production of the system model of high - speed bidding. based on the reasonable model - building, use software " matlab " to get the achievement at the beginning. and take a lot of figures from project experiment as the sample to practice on the net, at the same time lots of experiments have been done to test them
然後將經過0 - 1數字化處理的訓練集樣本送入網路，利用bp演算法訓練網路得出m組權值；之後採用實數編碼，將神經網路的權重作為ga的染色體，生成基因群體，再使用遺傳演算法尋優，使解碼得到的參數組合充分接近最佳參數組合，在此基礎上再用bp演算法對它們進行細調，從而來實現遺傳演算法和神經網路的結合，完成對投標快速報價系統的建模。分享友人
