查询词典 density of population

In a non-breeding, high density population of great gerbil we studied the dependence of stress and sex hormone concentrations, size of the mid-ventral gland and body mass of young males on presence of adult gerbils (≥1 year old) in social groups.

在非繁殖期高密度大沙鼠种群中，我们研究了胁迫以及幼年雄鼠的性激素浓度、腹中腺大小和体重对社群中成体(≥1年龄)存在的依赖性。

CVA was used to study the relationship between 6 cutting heights of 3, 6, 10, 14, 18 and 24cm, and 3 population traits of herbage yield, leaf area and tiller density, on manned swards of tall rescue grown under constant light and temperature regimes. The first canonical variate, which is very significant, explained 98%of separation among the heights.

在控制光温的人工草地上，高羊茅草丛群体的3个特征-牧草产量、叶面积和分蘖密度与刈割高度(3、6、10、14、18和24cm)的关系研究中采用CVA，结果表明，第一典型相关极显著，且第一典型变量能反映刈割高度间98％的变异。

The results from insect bioassay with peach aphid showed that the transgenic plants of pBI121AVA-GUS and pBI121AVAc-GUS were aphid resistant, evidenced by a 60.81%~50.63 reduction in insect population density, some plants were more than 97%.

The research employed nylon bag implantation and in vitro fermentation techniques. With the procession of in vitro fermentation, anaerobic fungal population density in the cultures were shown to increase, with the largest fungal populations growing on ryegrass leaves, ryegrass stem and straw occurring after 48 h of incubation.

结果表明，随体外发酵的进行，真菌数量逐渐增加，以黑麦草叶、黑麦草茎、稻草秸为底物时，瘤胃真菌数量均在48 h达到最大值，且真菌数量的最大值随底物木质素含量的上升呈下降趋势。
