released density

基本解释

Sometimes, the amount of female wasps and hosts in single tube could be based on the density of target pests and the amount of female wasps released on one plant.
也可以根据防治实际中目标害虫的虫口密度及单株放蜂数量来确定每管的接入寄主数和种蜂数。
Figures released by the Office for National Statistics show that population density in England is already almost double that of Germany and four times the figure for France.
根据全国统计局发布的数据来看，英国人口密度几乎是德国的一倍、法国的四倍。
