current density

基本解释

The potential and iso-current density distributions were obtained. The results agreed with classical electric principles.
通过对模型的计算得出了电位电流密度分布图，发现规律与经典电场原理相符合。
With the micro-discharge array, the glow discharge plasmas with high-pressure and high-current density can be formed to make DC plasma display panel.
它产生的高气压高电流密度辉光放电等离子体能够用来制作平面等离子体显示或光源。
If it can be synthesised, the ice will be about 25 percent less dense than the current lowest-density record-holder, developed by European researchers in 2014.
如果它能够被人工合成出来，那么其密度将比当前的记录持有者轻上25%——目前的最低密度冰由欧洲研究人员于2014年制成。

With industry-wide challenges in scaling current areal density technologies, this new platform allows HGST to design seven-platter drives in a standard 3.5-inch form factor that will cost-effectively extend the capacity and cost-per-gigabyte curve for many product generations to come.
ENGADGET: HGST develops helium-filled, high-capacity hard drives: no, they won't float away
Our ability to store electricity in batteries is improving, but current low energy density makes batteries an inefficient choice for large-scale storage.

The rumored device is equipped with pixel density specs that would make the new Nexus more eye-candilicious than the current iPad.
ENGADGET: Editorial: Turning point for the tortoise and the hare

the ratio of the electric current flowing at a particular point in a conductor to the cross-sectional area of the conductor taken perpendicular to the current flow at that point. It is measured in amperes per square metre ( symbol: J)
