Experimental results indicate that the phase parameters of GFRP fibres with respect to cutting direction change in the circumferential direction at cycle;
A measuring system based on the optical stylus method for on-line measurement of the waviness of a machined workpiece in the circumferential direction and the surface roughness of axial! profile has been developed. Its vertical resolution is 0.02～0.1μm and the horizontal resolution is 30～50μm.
For the problems of non-axisymmetric loads Fourier series expansion is adopted in the circumferential direction. This is a semi-analytic finite element method.
Methods Two-dimensional image of left ventricle (LV) parasternal short axis view (at the level of papillary muscle) were recorded in 15 patients with DCM and 15 normal controls. With special software for VVI we assessed the segmental peak systolic velocity (Vs), systolic peak strain (ε), systolic peak strain rate (SRs) and areas of LV after shortening in circumferential direction.
rotating cone feeders effectively improve mixing property of annular spouted beds,expecially in circumferential direction where mixing rate is boosted by as much as 10 times.
Results showed that non-uniform distribution of the flow, turbulent energyand catalyst particle concentration was found in the axial, radial and tangential directions and the mostcomplex part of the riser reactor was the feed zone.
The modeling results show that the flow pattern of feed spray is very complex and there are large gradients in axial,radial and tangential directions,which is similar with that of the gas solid two phase.
The results showed that the most complicated part is at the bottom of the riser reactor. The flow field,turbulent energy and catalyst concentration field of both gas and solid phases are characteristic of big gradients in the radial,axial and tangential directions.
THE THIRD IS A ROTATING BUSHING . INNER HOLE IS A ROUND ONE OF 6.7±0.2.THE SPIRAL PART IS DESIGNED BY MEANS OF PINS WHICH ARE ARRANGED ACCORDING TO EVERY 19MM ALONG LENGTH DIRECTION AND EVERY 120° ALONG CIRCLE DIRECTION.
This paper presents unequally spaced sectional ring-cutting method through equal residual height on generatrix direction and isoparametric on circle direction.
By analyzing the random contact and impact between drilling string and bore hole wall at arbitrary depth and circle direction in slim hole well, a dynamic model of whole drilling string is presented.
By investigation of characteristics of distortion of the gear tooth surface along the circle direction, the deviation is derived from distortion, and the definition of deviation with the geometrical invariability is proposed.
This paper offers the measured distribution of the surface temperature of horizontal finned tube along the circumference in natural convection heat transfer.
The shell motion is described by Donnell's theory including excitation forces and reactions of rings, bulkheads, stringers and fluid, which leads to the fluid-structure coupling vibration equation. Expressing displacements by velocities, applying modal expansion circumferentially and Fourier transformation longitudinally result in the shell's modal equations of motion.
Objective Using new echocardiographic technology, the velocity vector imaging (VVI) technology to evaluate the circumferential myocardial regional systolic function in patients with dilated cardiomyopathy (DCM).
using fine fiber texture), (2) increasing toughness of the fiber bundle interface, and (3) minimizing local curvature in waviness of the fiber bundles in the circumferential direction.
The angle-function (i.e., the circumferential angular coordinate) was defined in the image plane composed of the stream function coordinate (circumferential direction) and streamline coordinate.
The lattice parameters of epitaxial barium strontium titanate films with various thicknesses (from 6 to 960 nm) were measured as a function of temperature in the normal and tangential directions with respect to the film plane using x-ray diffraction.
The main attention is paid to the cases in which the material stiffness in the tangential directions is much larger than that in the transversal direction.
From its particle motion, this phase is likely to be a fundamental Rayleigh wave packet that arrived with an azimuth largely deviated from each great-circle direction.
First, we discuss the DOA deviation from the great circle direction that repeatedly appeared near the sunset and sunrise terminators.

The heat conduction problem is transformed into an algebraic eigenvalue problem which can be solved very simply by a perturbation method, the perturbation parameter being the small ratio between the coefficients of heat conduction in the gas and in the solid.
This paper deduces the linear polarization mode-LP mode in the optical fiber of the stepped refractive index according to the wave equation and scalar solution then lead into vector mode and introduces the method to classify combined mode.
A new type of self-lubricated porous metal bearing is introduced in this paper. In order to improve tribological behaviors of porous bearings, a special non-uniform distribution of permeability is considered. It has been manufactured by suitable production process. Theoretical analysis and experimental investigation show that, the new bearing has lower friction and higher load capacity than that of ordinary porous bearings, and there is no initial temperature rise and friction increase with the new bearing....
