The main objective was to improve comprehension of earth behaviors as building material by studying these two atypical cases of adobe production.
In fact, they are much used due to the facility with which they are made (diffusion and costs) and their relative success in predicting soil behavior as building material when applied together.
Materials and Methods The adobes strength was tested using a methodology developed by the Proterra network for compress strength test [12, 13].

Introduction Chromium nitride is one of the most commonly used coating materials for casting, machining and forming applications.
Their excellent wear and hardness properties combined with its corrosion resistance make this material very appropriate for mechanical components (molding dies, machining tools and sliding parts) [1].

Materials and Methods Soil Samples.
In recent years, various crudes, such as Shengli, Caoqiao, Gudao and other crude oil, has been used as raw materials of Qilu Petrochemical Corporation.
Compared with the same water content soil, this dry diesel-contaminated soil was more like a granular material, soil particles dispersed and show a state of “sand”.

Introduction The mechanical strength and plasticity index of material was measured by tensile test, it consist of the material yield limit, ultimate strength, elongation and reduction of area equal and so on .The traditional method is that the specimen is mounted on hydraulic universal testing machine, and the force of the tensile specimen is shown in force on the dial by the chuck drive mechanism, then the data displayed on the dial was manual read by the experimental operator, and the tensile curve is plotted on graph paper sandwiched between the rollers.This requires experimental operating personnel have a wealth of experience to be able to guarantee the accuracy of the data read, and data accuracy is also difficult to ensure, and an accurate description of the key indicators was not conducive to material.

Industrialized workshop construction system is to make a flexible and versatile workshop system by integrating various production processes, construction materials, architectural design, structural design, construction and construction equipment, to ensure good quality, fast design and construction, and to ensure its adaptation to various usage conditions and to form rich and diverse architectural images.
With only limited drilling, the various combinations will meet all kinds of different production conditions and different environmental conditions, under which the construction of the workshops is performed; 2, Stereotyped making of the transportation equipment, construction equipment, structural and architectural parts that are closely related to each other to adapt to a variety of production needs; 3, Application of uniform & stereotyped construction materials, products, spare parts, etc., and to create favorable conditions for the interchange & replacement; 4, Highlighting the form, size, and the way of production & installation for basic structures and construction components, and overall coordination, and the use of scientific organization and management in the overall arrangement of various aspects of the production, transportation, construction and installation etc.
There are single T-shaped plate, double T-shaped plates, and multiple T-shaped plates and double T-shaped plates are most commonly used. 2.3 Pre-stressed concrete saddle shaped shell plates Pre-stressed concrete saddle shaped shell plate is a new kind of hyperbolic & paraboloid shell structure of plate-girder combo, which shares the advantages of hyperbolic shape, thin-wall and pre-stressed, and features low structure height, good space stiffness and it saves material.

In recent years, research of the preparation of composite coatings by electroless composite plating shows that the rigid particles dispersed in the composite coatings can improve the wear resistance of the material surface.
The specimens do reciprocating friction under the same sliding rate, and a steel ball with a diameter of 3 mm and hardness of 204 HB is used as the grinding material, the load of 2 N and frequency of 3 HZ.
The bonding strength between the substrate and coating is directly related to the reliability and durability of the material using.

But the properties of magnetic levitation components and sensors are limited because of non-perfect property of magnetic material.
Simultaneously, in order to improve machining property of material, the ferrites must be assured of fine mechanical strength.
Since 1970s hot-pressing and hot isostatic pressing have been applied to prepare high density Mn-Zn ferrite material[1,2,3], but some problems, such as lack of equipments for fabrication, high cost and difficulty of fabrication technology, have not been answered.
