The long - term domestication of liquor - making microbes under the unique liquor - making environment of maotai liquor ( high temperature starter - making, high temperature stacking fermentation, and high temperature anaerobic fermentation etc. ) and the succession of microbial groups through heredity, mutation, growth and derivation etc. had accumulated abundant high temperature resistant, high acid resistant and high alcoholicity resistant extreme microbes
摘要茅臺酒獨特的極端高溫制曲、高溫堆積發酵、高溫厭氧發酵等釀酒環境長期對釀酒微生物進行馴化，各種微生物經過遺傳、變異、消長和衍化等微生物群落的演替，促成了釀酒微生態環境中豐富的耐高溫、耐高酸和耐高酒度等極端微生物的富集。Systematic cluster analysis was carried out on hu sheep in china in comparison with the same data of 9 asia sheep populations and 5 european sheep ( breeds in japan ) populations. 15 populations can be clustered in terms of gene frequency of 10 loci and 33 allele in blood enzyme and other protein variations
摘要以中國湖羊為研究對象，搜集國內外9個亞洲綿羊群體和5個在日本的歐洲綿羊群體的相同資料作為對照，根據控制血液酶和其他蛋白質變異的10個基因座位共計33個等位基因的頻率，進行系統聚類分析。Satellite laser altimeter return waveform is sensitive to the vertical canopy structure and the change of underlying ground elevation. it is optimal for mapping forest structure. the return waveform and the processing method are described. the relationship between laser waveform and canopy structure parameters is explored ignoring the clumping effects. the clumping caused that structure parameters are different from the actual value. to solve this question, a model by 3 - d canopy structure parameters is needed
星載激光測高儀的回波信號能夠靈敏反映地面植被組成和地表高度的變化，因此能夠用於探測森林地貌;首先對星載激光測高儀的森林回波信號及其處理方法進行了介紹，探討了在不考慮植被聚集情況下，植被組成與回波信號之間的關系;由於植被的聚集效應，例如樹葉群集成樹冠，會導致植被組成參數與真實值之間存在差異，這需要建立關於三維的空間分佈模型加以解決。Besides, proposing an adaptive variation factor to keep the diversity of population, and a novel crossover rule to widen the distribution space of children generations also effectively modified the sga
提出的相應技術包括：採集種群多樣性指標用以調整變異概率；改進交叉運算元，避免子代收縮，並提高其適應度；新增powell尋優運算元，加速局部搜索。In this paper, a method of emergence and survival of lacked allele is proposed, that is, selecting the characters missed in current population as lack allele set by comparing the character set with genes of the population, implementing simulated mutation to the individuals selected from the population by mutation rate, choosing the gene just mutated and its locus of the best individual from mutated individuals by fitness, and using it to mutate the genes in the same locus of original individuals
提出一種缺失基因復現和存活的變異方法，即根據字符集中的字元在種群中的缺失作為預選變異基因集，然後對待變異個體集進行預變異；選擇高適應度個體的對應變異基因和基因位，使其在原待變異個體集中擴散。分享友人
