Characteristic impedance theory In the engineering designs of strip-line, it is desirable to use the elliptic-wave guide at hand so that the elliptic strip-line can be obtained simply by changing the width of the strip instead of changing the elliptic waveguide.
The film thickness, line thickness and dielectric constant of material is fixed in the engineering designs of strip-line.

Response of Circular Footing on New Key Engineering Material - Granulated Blast Furnace Slag as Structural Fill Dr.
Granulated Blast furnace Slag (GBS) has good potential to be use as granular material in place of conventional granular materials i.e. sand and aggregate.
Common granular materials are conventional aggregate and river sand to fill such sites.
Scarcity of conventional materials in sufficient quantity required to search some other suitable materials to be use as granular fill.

The Construction Technique of the Beam Slab Structure Being Filled Large-span Prestressed Lightweight Materials Jun li Yuan Jun Li Yuan Pu Yang Vocational Technical Institute, Henan Province, China Key words: large span prestressed light material combined unit in cast-in-place concrete beam slab Abstract: With the rapid development of Chinese economy, more and more requirements of large public buildings, large space and has more functions, the engineering design, construction and bring many technical problems, in order to solve the technical problem, the construction of scientific research departments continue to research and development of new materials, new technology, new methods of construction, city of Puyang stadium the tennis project 44M*24M large span structure, adopts the ‘made of light material combined unit filled prestressed concrete cast-in-situ slab’ structure technology, solves the light, save steel, concrete, reduces the structure thickness, good economic practicability
Because of the cold weather and the average temperature at 5 degrees below zero, we take the engineering circumferential joint plug closely.
Concrete strength was detected from Tongda engineering testing Services Company in Puyang city with the conditions of test specimen and the springback test On February 15, 2011, and the strength met 95% of the design requirements and achieved the tensioning conditions of prestressed tendons.
The application prospects of the prestressed cast-in-place beam and slab structure filed by large span-lightweight materials (1) The prestressed concrete cast-in-situ hollow slab filled by lightweight materials can save 30% ~ 50% concrete and save 25% ~ 40% steel while assuring overall strength and rigidity
It is the developing direction of large span structure because of its saving raw materials, reducing the dosage of steel and concrete.

Experimental Study on Removal Characteristics of Ceramic Materials in Ultrasonic Aided High Efficiency Lapping Zhang Changjuana, Jiao Feng and Zhao Bo School of Mechanical and Power Engineering, Henan Polytechnic University, Henan,454000, China azhangcj@hpu.edu.cn Keywords: Ceramic materials, Ultrasonic aided lapping, Material removal rate Abstract.
However, due to their low plasticity, frangibility and non-conduction, engineering ceramics materials are difficult to process, especially in ultra-precise surface fabrication.

Until now, directional solidification technique becomes more and more important research area and active technology in the field of materials science and engineering.
Directional solidification of Cu-Ni alloys under deep supercooling [11] The intrinsic limitation of traditional Bridgman directional solidification makes men of science and engineering into dilemmatic situation: either solidifying the materials under lower thermal gradient, or pursuing higher thermal gradient with more complex equipments.
The development of directional solidification plays the same important roles in the field materials science and engineering.
