When the polarization is considered with zero biase,the UV/solar rejection ratios of Ga-faced solar-blind p-GaN/i-Al_ 0.33 Ga_ 0.67 N/n-GaN IHPs are 750,which meets the Tarsa’s experiment result of about three orders of magnitude.
The comparison result shows that calculation speed of the fast calculation formulae is three orders faster than those of REFPRO 6.01, the maximum relative deviation and mean relative deviation of the fast calculation formulae are within 0.56% and 0.025%, respectively.
The results show that due to the existence of compact oxidation film, aluminum rich layer and Al Fe alloy layer, the corrosion velocities of hot dipping aluminum steel lower two to three orders of magnitude than carbon steel in H 2S NaCl H 2O media.
实验结果表明 :由于表面氧化膜 ,富铝层和中间合金化层的存在 ,使得渗铝钢在H2 S NaCl H2 O体系中的平均腐蚀速率比碳钢低两到三个数量级 ;
The fluorescence of europium(III) was enhanced by about three orders of magnitude in the presence of 2.0 10~(-4)mol·L~(-1)TMA(trimesic acid) in aqueous solution at pH 6.The fluorescence intensity could be greatly increased when the system of Eu~(3+)-TMA was treated with La~(3+)and Lu~(3+).
The calibration graphs for V and Ti were covered by three orders of magnitude. The detection limit for V and Ti is 1. 5 and 0. 8 ng/ml, respectively. The proposed method has been applied to the direct determination of V and Ti in NIST SRM 1635 coal, and the results obtained are in good agreement with the certified values.
In this paper, we prove three types of rigidity results related to CAT(-1) spaces, namely the rigidity of the isometric actions on CAT(-1) spaces under the commensurability subgroups, the higher rank lattices and certain ergodic cocycles.
This is done by reducing the problem to the case of bipartite quivers of a special form and using a function DP on three matrices, which is a mixture of the determinant and two pfaffians.
We study boundary value problems for the time-harmonic form of the Maxwell equations, as well as for other related systems of equations, on arbitrary Lipschitz domains in the three-dimensional Euclidean space.

This wavelet basis is obtained from three wavelet generators by scaling, translation and rotation, and the wavelets are supported either by one corner triangle or a pair of adjacent triangles in the triangulation of level k - 1.

Our main results relate the convergence of the chromatic expansions to the asymptotic behavior of the coefficients appearing in the three term recurrence satisfied by the corresponding family of orthogonal polynomials PMn(ω).
The number of particles of the DNA-surfactant complex on the substrate was changed by varying the concentration of the initial solution within three orders of magnitude.
It was found that the incorporation of nanostructured silver clusters exhibiting the characteristic optical absorption band with λmax～ 420-440 nm increased the conductivity of cellophane films by two to three orders of magnitude.
Three adult human brain stems which presented an unilateral hyprtrophy ofthe striae medullares of the fourth ventricle were studied in serial Weigert sec-tions with the following results. The unilateral hypertrophy of the striae medullares is correlated with thehypertiophy of the contralateral nucleus arcuatus. In the hypertrophied nucleus arcuatus the fibers collect themselves towardsthe bottom of the ventral median fissure. The large bundle thus formed coursesdorsally along the raphe, crosses to the other...
The velocities of reaction of ethyl acetate with sodium hydroxide in dioxane- water mixture have been determined in seven different temperatures(5°,10°, 15°,20°,25°,30°and 35°).For each temperature,the compositions of solvent mixture are 0,5,10,15,20,25 and 30% of dioxane.We thus obtain 49 velo- city constants as summarized in the following table. At low temperatures,the velocity constant decreases slightly with decrease of dielectric constant of solvent.At higher temperatures,such decreases of k' become m...
