Firstly three directional high frequent multi-scale coefficients vector is formed by wavelet decomposition, then self-organizing neural network is used to compress coding.

Based on ASME VIII－2,the view points on stress classification,the definitions and characteristics of each kind of stresses,the distribution of the stresses along the thickness and whether the results from the finite element analysis,especially the results from three directional finite element analysis,can be simply resolved and classified were presented in this paper．

In this paper,a new method to measure directly the stress with stress gage is discussed,and the principle of two directional and three directional stress gages is presented. In this case of measuring the component stress with strain gage,the use of stress gage has the advantages of simple data processing and decreasing colloection passageway.

Let τ be the uniform triangulation generated by the usual three directional mesh of the plane and let H1 be the regular hexagon formed by the six triangles of τ surrounding the origin.

Existence and Construction of H1-Splines of Class Ck on a Three Directional Mesh

All three directional measures of elastic and shear moduli were lower in the osteopenic group compared with the normal group.

Three directional vibrations which were detected simultaneously by the accelerometer were analyzed using a statistical method.

In previous research, stylus movements regarding the hidden graph were sonified with three directional-predictive sound (DPS) signals, taking into account an exploration behavior and the concept of the capture radius.

With the aplication of the principle of octagonal ring force measuremen, three dimesional cylindrical grinding dynamoneter has been designed and construted. In veiw of the obvious difference in each directional rigidity of the equal-thickness of the rign, an unequal wall-thichness construction is adopted. Grinding test confirmed that using a ring of unequal wall--thickness will result in reducing diversity of three directional rigidity, increasing axial rigidity and improving anti -interference characterastic....

Hence., the reliability and accuracy of force measurement are thus enhanced.

Evaluation and studies of decorative granite further defined the relation between the ornamentation of decorative stone materials and the mineral composition of rocks. In evaluation of the granite rock samples should be systematically taken in equal space from a standard profile, identified by different methods and classified into different varieties and grades by mineral stoichiometry. Fracture structures of rock masses should be also studied in order to determine the relationship of primary joints and the...

Evaluation and studies of decorative granite further defined the relation between the ornamentation of decorative stone materials and the mineral composition of rocks. In evaluation of the granite rock samples should be systematically taken in equal space from a standard profile, identified by different methods and classified into different varieties and grades by mineral stoichiometry. Fracture structures of rock masses should be also studied in order to determine the relationship of primary joints and the three directional fractured surfaces for specifying the quarry stones and estimating, their recoveries. As to the grinding and processing of the rock materials it is recommended that grinding tools of standard seriation in seven grades should be employed for grinding, and micropowder must be used for fine granding the stones to raise their degree of finish. In addition, organic-inorganic composite bonding agent should be used for making the grinding tools.

By way of theoretical analysis, and numerical calculation and photoelastic test, this thesis analyses the interior stress distribution on railway worn profile wheel and rail under the action of three-directional loading, and obtains a series of important results. Provided two contact bodies are in the critical state of relative sliding, the tangential force is proportional to the vertical force. In order to indicate stress distribution and in accordance with the practical contact of wheel and rail, it is supposed that the proportional numerical value between tangential and vertical force is 1/3. Using superposition principle, it calculates the stress distribution under the action of threedirectional loading, and analyses maximum values of the stresses, in which, the transcendental function and complex integral are treated in the process of numerical calculation. The calculation results indicates, under the action of three-directional loading, one of the maximum contact normal stressse turns into tensile stress near the contact area, and the maximum value increases 58% of the situation only uneler the action of vertical force. And the results also show, under the united action of vertical and tangential forces, the maximum shear force turns out two peak values, one is near surface, and another below swrface, and the values greatens. Under the action of three-directional loading, the peak value of maximum shear force at the position of z=0.25a, belowsurfaee, exceeds maximum value of contact normal stress, to be 8 times that under vertical force. There is also analysis of fatigue and on failure on the contact of wheel and rail.
