For the shells which are made of one type of materials the whole entity, the frame stiffness is equivalent to cross section inertia moment.
Applying this method to the shells of different length, materials and number of frames, the same conclusion can be obtained.
The material of the pressure shell is Tc4.
The material of the pressure shell is Tc4.

Mechanical alloying (MA) process as a solid-state technique has been applied to synthesize nanocrystalline materials, quasi-crystalline phases, amorphous phases, supersaturated solid solutions and steady state or metastable state of intermetallic compounds (IMC) [11].
MA technique shows a good development in the field of advanced materials, such as W-Sn [12], Cr-Mo [13], et. al.
Experimental procedures Elemental powders of silver (Ag≥99.95%, d50=1.5µm) and copper (Cu≥99.8%, d50=21.5µm) were used as the starting materials.

Steel material for specimens is ferritic stainless steel; STS430 (similar to AISI type 430).
Japan Industrial Standards (JIS, JIS Z 2241[4]: method of tensile test for metallic materials and JIS G 4321[5]: stainless steel for building structure) specify that the yield strength is defined by 0.1% offset method for stainless steel.
Fu is tensile stress and Fy is yield stress of steel material.

By influence of the wave, surface microstructure of material is changed, and residual stress is produced in a big depth.
The material of blade was 65Mn steel, its elasticity modulus was 208 GPa, and poisson ratio was 0.288.
(2)With the effect of LSP, the blade surface layer material's residual stress increases obviously, and the maximum tensile stress reaches 412.25 MPa.

Another possible hypothesis would have been to take σzz = 0 for all layers (commonly used) but this assumption is debatable when we have a bi-phase material as it is the case here.

As the location of rural economy, politic, education and living service, rural environment is the foundation materials conditions of rural economic and social sustainable, stable and coordinated development.
Internal roads of different materials Figure 2.
The houses in rural areas mainly includes adobe houses, hybrid-structure houses with bricks and wood, hybrid- material house with bricks, cement and sand, reinforced concrete houses.
After the ownership of the land is decided, rural houses were constructed according to the owner’s own idea, so the building materials, building styles and building structures of the houses are different, meanwhile rural government has little intervene, which leads to the disorder of the rural housing visually (Fig. 4).

Materials and Methods Quality of Experimental Water.
It was due to lesser the H2O2 dosage lesser HO• was catalytically produced, the HO• firstly attacked the chromophore; when the amount of H2O2 was more, COD removal rate continued to drop, it was because the COD value was heightened by K2Cr2O7 oxidizing the rest H2O2, H2O2 had the invalid decomposition to produce H2O and O2, even if HO2• had been produced in the process of generating these end products, the oxidation ability of HO2• was inferior to that of HO•, Some difficult degeneration materials were unable to be oxidized resulted that the COD was not removed thoroughly [2]; the macromolecular refractory material was consumed completely as UV254 removal rate tended to level [3].
