查询词典 experimental error

In my theory of absolute velocity of matter, I will show that the variation within all these experimental results, not only IS NOT due to experimental error, but that the measure of the variation itself is of paramount importance to our understanding of physical laws, and indeed of the whole universe.

With the combination of lighting, cooling and heating under daylighting, the study on the effect of the key characteristic parameters on total energy consumption is provided. The validation of the comparability of daylight distribution for building antetype and model is made through theoretical analysis and simulating calculation in the thesis. Due to the variable sky condition, daylighting factor is used for experimental validation instead of illuminance. The error analysis of several testing methods used in the experiment is conducted, followed by the experimental validation of the effect of WWR, sill and transmittance on daylighting factor distribution.

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 .
