The plasma ignition threshold of metal is got through experimental and numerical study. The vapour and plasma ignition times of the target are got based on the equation of heat conduction and cascade model. We suppose that the plasma is ignited when generations of new electrons are born in vapour generation time. The influence of temperature on the thermodynamics and optics parameters of material also have been considered in the model. The resulting theory has good agreement with the experiment and overseas report. A blade method to measure the laser spot is given in this paper with validation and error analysis. The plasma threshold of metals in atmosphere and water ambients both are diagnosed with the light deflection and piezoelectric transducer. A Q-switched pulsed Nd:YAG laser operating at infrared (1064nm), visible(532nm) and ultraviolet (355nm) wavelengths has been used. Al、Fe、Cu are used as targets and get a similar results with both method. Theoretical and experimental analyses are applied on the influence of wavelength on the threshold have been done, both of which have shown that the plasma threshold of metals decrease as the laser wavelength increases; The plasma threshold of metals are higher in water than in air and the pressure of the shock wave in water is five times higher than in air .

Results showed that, the specific refining energy consumption is decreased with increment of rotation speed of the primary refiner. At freeness level of about 670 mL CSF, for example, the specific refining energy consumptions is 363 kWh/t o.d. at 3000 r/min, and 305 kWh/t o.d. at 3500 r/min, which is equivalent to 16% energy saving, furthermore the specific energy consumption is only 265 kWh/t o.d. at 4000 r/min, which means 27% less refining energy required. At the same time, pulps produced at higher refiner speed have higher strength properties and lower shives contents. There is little change of optical properties of the pulps.
