摘要:

The effect of dielectric constant on surface discharge of polymer insulators (polyethylene, polycarbonate, polytetrafluoroethylene, and polyamide) with right cylindrical shape was investigated. The experimental results showed that dc flashover voltage was decreased with increase of dielectric constant in polymers.

摘要:

The stimulated emission cross section of the 1.061‐&mgr;m transition (R1—Y1) in Nd: YAG has been measured and is (5.1 ± 0.5) × 10−19cm2on the same scale that assigns the value 8.8 × 10−19cm2to the 1.064‐&mgr;m line. The thresholds of the 1.061‐ and 1.064‐&mgr;m lines have been determined over the temperature range of 100–300 °K and are equal at 229 °K.
