When machining solar silicon based on EDM,the machining efficiency is determined by silicon body resistance,which is not the same if the conduction mode is different.

The Influence of the Bulk Resistance and Shunt Current on the Characteristics of GaAs Solar Cells;

The volume resistance and surface resistance measured by three electrodes and the resistance between two electrodes (R) of carbon fiber reinforced cement(CFRC) were studied.

Both volume resistance and contact resistance of the modified composite bipolar plates decreasd obviously after modification.

The results indicate that measured SE of the system increases and the volume resistivity decreases sharply with increasing of doped PAN.

As the axial fan has 4000 hr per year regulated speed in motion in Anqin Copper Mines Xifeng Well, so applied reconstruction of liquid resistance regulated speed technology, it can recomize power cost RMB 200 thousand.

Thte starting characteristics of mine fan driven by coiled asynchronous motor in series connection with symmetric liquid resistances to the rotor is analysed,and the calculating method of liquid resistance is introduced.

To meet the needs of different applications and loads, the conventional starting mode of the high-voltage cage liquid resistance starter is improved.

Influence of the self-resistance on the linearity of humidity sensitive resistor;
