The results showed that the mean proportion of polymorphic loci ( ppb ) of anabasis aphylla, which comprised 3 subpopulations ( 58 individuals sampled ), generated by 16 primers was 94. 56 %, the value of ppb of ceratocarpus arenarius, which had 4 subpopulations ( 80 individuals sampled ), using 16 primers was 98. 00 %. the paper had proved that the higher genetic diversity and the genetic differentiation existed in the populations of boih anabasis aphylla and ceratocarpus arenarius, while the latter had much more genetic diversity than the former. moreover, the study discussed the shannon information index and nei ' s gene diversity index of the two species natural populations, which indicated that there were more genetic variations within the subpopu
另外,通過rapd資料的聚類分析及相關性分析研究,發現無葉假

木賊亞種群遺傳多樣性水平不僅與
土壤含水量( w ) 、鉀鈉離子濃度( k + na )和氯離子濃度( cl )呈顯著的正相關( p 0 . 05 ) ,還與
土壤中有機質( som ) 、全氮( nt )和全磷( pt )含量呈顯著的負相關;同時,角果藜種群的遺傳多樣性水平與
土壤中有機質( som )和全氮( nt )含量呈顯著的正相關,而與co _ 3 ~ ( 2 - )濃度呈顯著的負相關;除此之外,其它
土壤生態因子與兩物種遺傳多樣性水平的相關性均不顯著(卜0 . 05 ) 。
Conscious that the human organism, normally capable of sustaining an atmospheric pressure of 19 tons, when elevated to a considerable altitude in the terrestrial atmosphere suffered with arithmetical progression of intensity, according as the line of demarcation between troposphere and stratosphere was approximated, from nasal hemorrhage, impeded respiration and vertigo, when proposing this problem for solution he had conjectured as a working hypothesis which could not be proved impossible that a more adaptable and differently anatomically constructed race of beings might subsist otherwise under martian, mercurial, veneral, jovian, saturnian, neptunian or uranian sufficient and equivalent conditions, though an apogean humanity of beings created in varying forms with finite differences resulting similar to the whole and to one another would probably there as here remain inalterably and inalienably attached to vanities, to vanities of vanities and all that is vanity
人體組織通常能夠抗得住十九噸的氣壓169 ,可是一旦在地球的大氣層里上升到相當的高度,越是接近對流層與平流層的境界線,鼻孔出血吸呼困難以及眩暈,隨著算術級數就越發嚴重起來。他曉得這一點,尋求解答時就設想出這樣一個難以證明是不可能的行之有效的假定:倘若換個更富於適應性,解剖學上的構造也有所不同的種族,說不定就能在火星水星金星

Seven plots selected from wanglang reserve were distributed in different types of forest and at different altitude, and different plot has different microclimate. soil property, microbial population, soil nutrient content of forest soil were determined in wanglang natural reserve, from may to october 2002 to july 2003, the ecological distribution of three main groups, bacteria, actinomycete and fungi were determined in the forest soils by the cell enumeration methods. six kinds of physiological groups, including ammoniation bacteria, nitrification bacteria, nitrosification bacteria, aerobic autogenesis azotobacter, aerobic cellulose - decomposing bacteria and anaerobic cellulose - decomposing bacteria were enumerated by the most - probable number ( mpn )
