Uygur architectural decorative patterns classification and the development and application of information technology GuangLi1 Xinjiang Construction Vocational and Technical College, China Email:xjlg5677@163.com Keywords: Uygur architectural decorative patterns;Geometric pattern;Plant grain;Text lines and Classification of patterns;Patterns of development and application of information technology Abstract:Uygur architectural decorative patterns is an important part of Chinese traditional culture , which is reflect the history of the nation's art form.
At second ,patterns stored in paper records are also facing problems susceptible to corrosion and damage; Third, mastering the craft of decorative patterns Uyghur craftsmen in the community is not given more attention, there is no economic security, the number gradually reduced, resulting in the loss of the traditional process gradually.

Although the proof of principle has been obtained some time ago, recently a number of studies have been published aimed at optimising the joining operations to obtain best joint strength and reduced distortion and residual stress.
Strength is also improved due to a variety of mechanisms, including grain refinement, creation of additional obstacles to dislocation movement, etc.

It has been determined that was made first thin grout after grained paint on grout that occurred from sand, chaff and lime, almost whole doorjambs and floors was broached or broken, locked stairs that made by cutting from limra stone, first was lay over bulk mosaic and after wood.
In this table, emphasized numbers of floor are cumulative of ground floor and full upper floors.
Table 1: Allowed maximum numbers of floor Earthquake area Maximum numbers of floor 1 2 2,3 3 4 4 d) Limitation of floor height in pile buildings, maximum is 3,0 m through from floor to floor. r.
Numbers of Total crucial point is 17424.
In entrance of structure, Limra doorjamb and other küfeki doorjambs, profiles and grouts on wall covering was ripped, grained paint under the grout was cleaned by raking.

Furthermore, under a non-breaking load, the length of a crack that does not propagate is approximately one crystal grain [4,14].
Furthermore, considering that the length of a crack that does not propagate is approximately one grain [4], the condition in which a fatigue crack does not initiate or propagate beyond a small crack can be considered a criterion for bending fatigue failure.
The number of elements was determined by investigating the convergence of the analytical values of the actual stresses at the critical point.
The investigation was performed until the change in the values with an increase in the number of elements was less than 1%.
Based on the fatigue test method of Kato et al. [1], the number of non-fracture discontinuation cycles was set to 1.0×107 for normalizing and 3.0×106 for thermal refining.

It is the result of dislocation slip, grain boundary motion, plastic deformation and interplanar cleavage.
The dynamic radial distribution function and corresponding number density integral for variable time and temperature were calculated to explorer the relationship between the crack growth and temperature.
Based on the simulation results the atomic radial distribution function g(r) and the corresponding number integral are calculated and over a given trajectory.
Composing all the number density RDF integration curves under changing temperature and time cases and we obtained a plot as Fig. 11.
Number density integration curves The RDF curves correspond to crack growth at 200 K,300 K,500 K,700 K,900 K and 1100K are illustrated in Fig. 12.

The procedures for identifying the material are based on the following determining factors, which are used for parameters: · Age of the sample · Composition of the tadelakt (original Moroccan or to whatever recipe it has been mixed) · Pigmenting (which pigment and weight/%) · Location of manufacture (Germany/Morocco) · Technology: Technique (with stone or trowel), material (application consistency), procedure (e.g. with a rotary movement) · Number of tadelakt layers · Experience/personal style of the plasterer · Plaster base of the tadelakt plaster · Earth/lime plaster interface (lime slurry, wet in wet, combed key) · Method of hydrophobising the lime plaster (soap, wax, number of applications) All investigations undertaken to date have been preliminary tests, which were carried out in the manner of the most closely corresponding DIN.
The predetermined number of test samples has not always been met in all the test series because the main focus of attention was initially on the broad scattering of results from the, as far as possible, different test samples in order to estimate the reaction tendencies.
· Earth plaster base: natural building earth, mixed grain-size washed sand 0-2mm, barley straw 30mm
· Earth finishing plaster: natural building earth, mixed grain-size washed sand 0-2mm, barley straw 10mm
The samples differed according to the following parameters: · Age (between 6 and 16 weeks) · Pigmentation (8-10% and over pigmentation) · Number of saponification operations (1× – 3×) · Plaster base (Fermacell, lime bonding plaster, earth finishing plaster, calcium silicate) During preparation of the tests the individual layer structures already demonstrated interesting details: Older samples had a much sharper cut edges after drilling.

Macro-transport (MT) models [1] are used to describe solidification over large distances within the castings whereas micro-models [2-3] which include solidification kinetics (SK), nucleation and growth laws describe microscopic scale changes such as micro solute transport, volumetric grain density, grain growth, phase transitions and many others.
The effect of radiation heat transfer on the grain size evolution was however not coupled.
In order to save computational time, subsequent calculations were done using 10000 numbers of nodes.
Previous models Voller and Swaminathan, [21] produced solid fraction plots that have jump discontinuity at the beginning and end of the curves which were reduced by applying large arbitrary numbers (about 108).
Additionally, large arbitrary number was not applied in the current work and the transition from liquid to solid maintains a smooth changing function till the end of solidification.

The obtained effect is due to the formation of a large number of substrates for the heterogeneous nucleation of silicon crystals.
It is also worth noting that structure of the silumin cast from the lowest temperature includes a coarse-grained α(Al)+β(Si) eutectic, surrounded by silicon crystals and oblong precipitates of the AlFeSi phase.

There are a number of basic material elements that constitute a flexible circuit as Figure 1 illustrates: a dielectric substrate film (base material), electrical conductors (circuit traces), a protective finish (cover lay or cover coat), and, not least, adhesives to bond the various materials together.
Lower thickness of EN thickness will produce a more nodular surface morphology giving rise to higher penetration of immersion gold along the electroless nickel grain boundaries.
