when the small angle deviation on one side of the minimum deviation angle of each prism is controlled,the scanning range of laser beam in the horizontal and vertical direction is not less than 500 μrad,and the scanning precision of the device is superior to 0.2 μrad.
Based on the method of minimum deviation angle, man can obtain the accuracy of measuring refractive index of glass at 3×10-6 with fine apparatus for measuring angle, but the classical princip1e formula quoted by these literatures have principle formula error about 4 ×10 - 4 order which lead to an erroneous measure result.
When The goniometer is used as spectrometer, the design of 2:1 driving mechanism of self-hunting minimal angle of deviation method is applied. Synchronous error of the driving mechanism is estimated, and the error data are given.
By determining the incidence angle and the angle of deviation, the author has found a certain law to offer a fast and simple method to the experimentation, and studied at the same time some problems discovered in the experiment.
Regression analyses of experimental data indicated that the relationship between hue angle difference and the magnitude of perceived color shifts could be described quantitatively by an exponential function, and a linear function could describe quantitative relationship between hue angle difference and deflection angle of color shift vector from constant hue line.
The distributions of loss and deviation angle of every blade row, and blockage factors are evaluated using tested total temperature and total pressure at inlet and outlet of compressor, as well as the endwall static pressures.
In order to minimize the deviation angle of the new prism, an additional angle was designed.
Experimentally, its deviation angle is smaller than 3' in the wavelength range of 540-670 nm.
The increase in the intergranular cracking with increasing deviation angle at the |Δθ| values less than 5° could be understood in terms of the increasing GB susceptibility to the GB damage due to air environment.
These operators depend on the differential cross sectionh(?p, q?, cos θ) which is a fonction of energy ?p, q? and of the deviation angle θ.
The effect of the angle of deviation of the original boundary of the discontinuity on the two-dimensionality of the flow is estimated.
In particular, the angle of deviation of the director at the surface from the alignment direction at the exact temperature of the jump in pitch is expressed in terms of the anchoring potential.
It was found that when the angle of deviation of the substrate plane is from the (110) NGO plane, twinning of one or both twinning complexes in YBCO may be suppressed.
The second harmonic amplitude has been studied as a function of the external longitudinal magnetic field, the current frequency, and the angle of deviation of the microwire anisotropy axis from the circular direction.
Finally a simple model is used to evaluate the mean angle of deviation from the ideal lattice.
A linear solution to the problem is constructed under the assumption that the deflection angle of the flap is small and the difference between the length of the plates is of order unity.
0.63), and the deflection angle of the protons reflected inside the crystal is equal to 1.39 ± 0.04 in terms of the critical angle for channeling under the conditions of the experiment (170 μrad).
In the linearized approximation, the Lyapunov stability of vortices is proved and the deflection angle of a light ray in the gravitational field of the vortex (gravitational lens effect) is calculated.
A clear relationship between the final electron energy and the deflection angle is shown.
So, in the present study, the effects of the deflection angle of Coanda nozzle on jet structure and the distribution of impinging pressure at the plate surface are investigated numerically and experimentally.
