On the other hand, few prototypes were made for receiving necessary information on manufacturing process, possibility of placing the conductive traces on any ceramic materials, operating principle of entire system.
The adhesion to substrate material was also satisfying, despite the substrate material was not intended for using in screen printing method.
We also plan to define impact of environmental elements, made from different materials, like wood, concrete, plaster, between transponder and reader for read range.

So it can achieve accurate determination of the pH value of the material.
With the development of science and technology, the method of measuring pH value will be more convenient, more automatic and precise.

In optimal case fiber mat reinforced materials are isotropic, because the fiber bundles are ideally randomly oriented.
Describing the fibrous reinforcing materials is not an already solved problem therefore there are a great number of theoretical approaches and experiments in this area [6-13] while computer aided modeling of these materials is also a frequented researching field [14].

Pipe Length Limit Analysis to Tunnel Vertical Well of Natural Gas Pipeline Xin Tian 1, a, Chi-yuan Ren 2,b 1 Apply Technology College, Southwest Petroleum University, Nanchong 637001, China 2 College of Sciences, Southwest Petroleum University, Chengdu 610500, China aemail:yuxin0824@126.com, bemail:renchiyuan@163.com Keywords: Stress analysis, Natural gas pipeline, Tunnel vertical well, Limited length.
For plastic materials, failure in the form of yield, so the ultimate stress for the yield limit, namely:for brittle materials, failure in the form of fracture, so the ultimate stress for the ultimate strength, namely: In order to ensure the strength of security components, the danger point at the maximum working stress is not allowed to (or near) the material ultimate stress.
Material allowable stress values may be the ultimate stress divided by a number n to be greater than 1, namely: Where, n is called the factor of safety, according to a variety of materials and their different working conditions from the specification or design manual found. 2.2.3 Calculations of pipe strength The strength calculation must considerate the following factors, including gas pipeline wall thickness selection, pipe stress calculation, and strength.
Mainly refers to the basic parameters of control system components in the calculation of the temperature of the pipe, installation of temperature,, allowable stress, material grades, elastic modulus, Poisson's ratio, medium density, density of pipe material, insulation thickness and density.

Today, the plastic materials are the terms used to describe an extremely large family of very different materials with different characteristics, properties and uses.
Plastics are not just one material, but a wide family of different materials.
Materials Aggregates.

One is the high-frequency with small-amplitude which is good for delivering materials and raising its capacity.
Materials in the screen surface and screen box form the vibration mass.
Thus the amplitude must be large enough to loose the materials, or the materials would stick together and lower the screening efficiency.
Elliptical vibration makes materials rolling in the screen surface and the screening time fully used.
Thus, the vibrating screen can complete the processes of materials loosing, layering and discharge effectively.

This reduces material costs, labor costs, testing equipment costs and overall project expenses. 2.
