查询词典 impedance

The principle difference between RS-422 and RS-485 is that the RS-485 driver can be put into a high impedance, tristate mode, which allows other drivers to transmit over the same pair of wires.

区别RS-422和RS-485的准则是RS-485驱动器可以转入高阻抗、三态模式，允许其它驱动器驱动在同样的对绞线上传输信号。

An occluded corrosion cavity simulated cell was designed,and electrochemical impedance spectroscopy and polarization curves measurement were employed to study the effect of MoO42- on the development of underscale local corrosion of carbon steel in neutral NaCl solution.

设计了一种能够模拟垢下局部腐蚀自催化过程的闭塞电池，采用极化曲线和电化学阻抗方法研究了MoO42-对N80钢在近中性NaCl溶液中闭塞区内化学及电化学状态变化的影响。

The inhibition mechanism of MoO42- was that MoO42- transformed the hydrate ferrous oxide deposition film from anions selective to cations selective,and the cathodic process of underscale local corrosion was suppressed when it migrated into OCC.Meanwhile, the migrated MoO42- resulted in increasing the impedance of the film on the substrate metal and so inhibited the anodic process of the corrosion reaction inside the OCC.

MoO42-的作用机制在于使水合氧化铁腐蚀膜由阴离子选择性变为阳离子选择性，H+可以从膜下扩散出去，而Cl-难以扩散到膜下富集，抑制了腐蚀反应的阴极过程；同时MoO42-迁入闭塞区后增大了电极表面膜层阻抗，抑制了腐蚀反应的阳极过程。

Increasing the dimensions and burying depth of the grounding electrode, as well as the ground conductivity can effectively decrease the grounding impedance.

Since development of volcanic layers and volcanic mounds in basement in Tazhong area, using seismic exploration is usually difficult to acquire better seismic data in the interior of vocatine and below(mainly caused by shield of volcanic layer), but using MT exploration may not produce such problem, because the electromagnetic wave does not suffered from the shield of higher resistance layer; especially the volcanite has the feature of higher magnetic susceptibility and impedance, which provides excellent c...

由于塔中地区的火山岩层及基底火山岩丘发育，采用地震勘探方法通常难以在火山岩内部及其以下获得比较好的地震资料(主要是火山岩层的屏蔽作用)，而利用MT勘探则无此问题，因为电磁波不受高阻地层屏蔽，尤其是火山岩具有高磁化率和高电阻率的特征，从而为在该区应用大地电磁和磁力方法识别火山岩薄层及基底火山岩丘提供了得天独厚的条件。
