For basnaesie from Zhushan,Hubei Province,only a politype 6R was observed,in samples from Bayan Obo an eutectic-oeriented intergrowth of 3R and 6R was found,and the eutectic twin of 3R type was observed.
A planar DC SQUID gradiometer made from high Tc YBCO thin film has been fabricated on a 10×10mm 2 SrTiO 3 bicrystal substrate. We obtain a magnetic field gradient resolution of 443fTcm -1 Hz -1/2 in the white noise region and 2.07pTcm -1 Hz -1/2 at 1Hz for the gradiometer.
A novel soft-switching twin arc pulse MAG welding inverter
It is the first time that a phase compensation for real roots, i.e., the twin lead/lag loop which is facile for engineering applications, is used in superheated steam temperature control.
Immune hematological characteristics and immune instability in twin species of common vole (the Microtus arvalis group) at diffe
Under these conditions, two flow patterns were observable, which differed from each other by the intensity of the transverse oscillations of a system consisting of attached twin vortices and the near wake.
In these schemes the cavity is closed on a flow domain bounded by a closed streamline encircling either a dipole or twin point vortices with circulations equal in magnitude and opposite in sign.
It has been shown that the so-called dispersionless localized waves (polaritons) can exist in a bicrystal formed by two identical crystals.
The exact analytic expression is derived for the velocity of the wave propagating along the bisector of the angle between the optical axes in the upper and the lower parts of the bicrystal.
The formation of grain boundaries of the general type, along with small-and large-angle symmetric grain boundaries with the ? ? axis in the epitaxial layers grown onto bicrystal substrates by the method of thermal migration has been studied.
X-ray specular reflection under conditions of extremely asymmetric noncoplanar diffraction from a bicrystal
The angular dependence of the intensities of X-ray specular reflection has been rigorously analyzed under conditions of noncoplanar grazing Bragg diffraction in a crystal coated with a crystalline film (bicrystal).
