A successional Artemisia ordosica and A. frigid community, located on the eastern edge of the Tengri Desert in Alashan Left Banner, Inner Mongolia, was selected as an object for study. Densities of the plants and total nitrogen and available phosphorus in 0~20 cm soil layer were measured of the 400 quadrates (4m×4m) in the sampling plot (80m×80 m) for analysis of relationship between N/P ratio in the soil and plant density thereupon and between the two in spatial heterogeneity.

选择腾格里沙漠东缘内蒙古阿拉善左旗境内的油蒿＋冷蒿群落为研究对象，在80m×80m样地400个4m×4m样方中，调查了油蒿和冷蒿的密度，测定了0~20cm土层中的全氮和有效磷，分析了土壤氮／磷比与植物密度之间及其空间异质性之间的关系。

Or 5 pollen densities and 0 control tested; 6 replicates per test

4或5花粉密度和0花粉对照；每测试有6个重复

Knowing this boundary would help scientists understand the behavior of matter when it is scrunched to extraordinarily high densities.

了解这一界限将会有助于科学家们弄明白当物质被挤压成极高密度时所表现出的特性。

Densities and viscosities of solutions were used to calculate excess molar volumes and excess viscosities respectively.

混合溶液的粘度随温度的关系用Andrade公式进行了关联，各组成关联的相关系数接近于1。

These cause temperatures to vary resulting in changes in stream densities and viscosities.

这些造成了温度变化，导致了流密度变化和粘度的变化。

Finally, the influence of defect densities on the dependence between grain barrier and gate bias was examined by device simulation results.
