平均密度

Area of 12 square kilometers, household residents in 8334, population 27,686, and the population density 2037 people per square kilometer.

面积12平方公里，户籍居民8334户、人口27686人，人口密度平均每平方公里2037人。

He based this relationship, using astronomical parameters calculated that each of their counterparts in Gua stars the average orbital velocity and density values were a secret.

他依据这个关系，利用天文参数进行计算，证明出每一对应卦位所属星体的平均轨道速度和密度均分别为一个密值。

The average iR drop accounts for about 74% of the total voltage losses during the C-D cycle at current density of 60 mA·cm-2,suggesting the voltage efficiency of vanadium redox-flow battery single cell with graphite felt as electrodes and Nafion 117 as battery separator,was limited by the cell ohmic internal resistance.

以石墨毡为电极、Nafion 117作隔膜的全钒液流单电池，在60 mA.cm-2电流密度下，每一充放电循环的平均iR降约占总电压损耗的74%，表明该电池的电压效率受制于电池的欧姆内阻。

The density of particulate matter in north China averages 112 microgrammes and that in the south, 88 microgrammes, he said at a forum on China's investment environment in Chengdu, capital of southwest China's Sichuan Province.

他在一个关于中国西南部四川省的省会成都市的投资环境的论坛上说，空气中粉尘微粒的密度在中国北方城市平均为112微克，在南方城市为88微克。

电流密度的测试结果表明随压缩速度的增加，链结构被压溃更严重，同时由于电场力与粘性力的比值降低，不利于被破坏的链结构的恢复，颗粒间局部平均电场强度降低，从而导致抗压强度降低。
