查询词典 decrease in population

Then, introducing the improved straight-line stabilization method to control the chaotic phenomena in the models, a controller is designed to stabilize the biological population in the oribits where the fixed points lie on, thus eliminating the chaotic phenomena in population to keep the population system in persistent existence.

This paper starts with the Naroll-Bertalanffy's hypothesis of the allometric growth of urban-rural population, namely and Sherratt's model about the distribution of urban population density, which are both based on the Christaller-l o ··sch's central place hypothesis and the hypothesis of supposing the regional population movement on the ideal land surface is similar to Brownian movement process.

基于中心地假设，从城市人口分布的Sherratt模型和Naroll Bertalanffy的城乡人口异速生长关系出发导出关于人口分布空间动力学和城市扩展时空过程的数学模型，然后借助Batty等关于城市生长的DLA -DBM模拟结果证明人口的区位选择过程与城市的分形形态存在着内在关系。

When the larvae were fed with Apricot and apple-pear the death rate of the larvae increased,the larval and pupa stages prolonged, the pupa weight decreased, female adult life shortened and the average fecundity.The age-specific life table of codling moth indicated that the trend index of codling moth population fed on Jonathan apple, Red Delicious apple, Zhangye number two apple, Chinese pear-leaved crab-apple and Crisp pear were more than one. Experiment population quantity was at the growth condition. The trend index of codling moth population fed on Apple-pear and Apricot were less than one.
