Based on the formula,tangential stress, radial stress, axial stress is as follows: (1) The paper thickness and plastic thickness is (0.0225 +0.17) mm,the diameter of the n-layer paper and paper-length formula is as follows: (2) Calculating (1) and (2),the layer number is 8.The average shell diameter is 21.5mm,the average circumference La=67mm.So the theory length of the rolling layer is 537.57mm.L = 546.5972mm,which means that 1.5mm rolling shell requires 547mm thickness of power cable paper. 2) Shell strength: the longitudinal tensile strength of power cable paper is 13KN/m,transverse tensile strength is 6.5KN/m,paper thickness h is 0.17mm±0.008mm,the paper width cross-sectional area S is 170mm2, the tensile strength of 1m wide paper is 6.5KN[5],pull strength is 38.29MPa.The shell radius r is 10mm; wall thickness h is 1.5mm.Based on cylinder strength theory
C．Pharmacy to suppress Propellant uses pressing process of a number of partial pressure.According to the density of black powder and to suppress the pressure relationship[8],as shown in Table 1,combined with the pressure of drug trials,when the pressure reaches 300MPa the shell is broken.When the shell pressure reaches 200MPa and 250MPa, the shell consistency is better,the charge density respectively reach 1.75g/cm3 and 1.78g/cm3,so 250MPa pressure should be selected.The propellant grain density is 1.78g/cm3.With center hole to suppress,the pore diameter is 4mm,hole depth is 1mm.

The inclusions always present at the matrix or grain boundary with shapes of film, particle or cluster, which would reduce their processing properties and service properties markedly [2].
Fig. 2 and Fig. 3 show the relationship between purification and the mesh number per inch (the less mesh number per inch, the larger pore size of mesh), in which the values in zero point of horizontal axis were those samples without filtered at the corresponding temperature.
According to the experimental results show α changed with the mesh number per inch obviously and the change rule varied with the filtering temperature.
After elevating filtering temperature to 750°C, the large pore of mesh (8 meshes per inch) has poor purification effect as compared with the middle or the small pore of mesh (16 or 30 meshes per inch). 0 5 10 15 20 25 30 0.00 0.05 0.10 0.15 0.20 0.25 0.30 0.35 0.40 Area percentage of Inclusion/% Meshes/inch T650 o C T700 o C T750 o C 0 5 10 15 20 25 30 0.0 0.2 0.4 0.6 0.8 1.0 dave/mm Meshes/inch T650 O C T700 O C T750 O C Table 1 Relationship between mesh pore size D and dave Mesh number per inch Mesh pore size, D /mm dave/mm Ratio of dave/D 8 3.18 1.02 0.32 16 1.59 0.64 0.40 20 1.27 0.39 0.31 30 0.85 0.37 0.44 At lower melt temperature, the large viscosity of melt and the oxidation random involvement may occurred would influence the separating of inclusion from melt.
The ratio of the mesh pore size D for different mesh number per inch with dave, listed in Table 1, ranges from 0.3 to 0.45. it indicates that there is obvious capillary effect as melt flows through the mesh pore during filtering process and the maximum diameter in the filtered melt is far smaller than the mesh pore size.

Factors affecting the corrosion of these bricks were previously investigated in a number of studies [1,3].
Some of the main corrosion parameters are the presence of a slag coating on the brick, the brick microstructure, the quality of brick components like periclase grains, type of antioxidants, graphite flakes, the resin used, thermomechanical loads, slag chemistry, viscosity and so on.
In the latter case, a large number of replications is required to get precision and a large spead of data (e.g.10-50% variation) is common.
Because of the limited number of experimental data only seven testing outputs were compared to measured data (Table 2).
Using an extension of this approach, large numbers of plant data on refractory recess thickness, slag chemistry, number of heats per day, type of steel, slag/steel volume ratio, tap-to-tap time and temperature, and the degree of mixing of ladle can be used to create a model to predict refractory corrosion.

Al-powder having three different average grain sizes (25, 100, 180 µm) and two different kinds of ß-SiC powder (10, 40 µm) were used in preparation of the mixtures. 5% pure Cu powder with an average particle size of 50 µm was added to each mixture to promote densification during hot pressing.

Comparing the porosities of the samples it can be stated that a less number of pores with a larger size develop due to cold pressing and sintering procedure, however, hot pressing results in more 0,00 0,50 1,00 1,50 2,00 2,50 0,20 0,20 0,20 0,20 0,29 0,29 0,63 2,50 2,50 10,00 18,00 RPS Area fraction (%) 5 % SiC, CP 25 % SiC, CP 20 % SiC, HP v=20 K/min v=30 K/min Ni Ni Cu 0,000 0,020 0,040 0,060 0,080 0,100 0,120 0,140 0,20 0,20 0,20 0,20 0,29 0,29 0,63 2,50 2,50 10,00 18,00 RPS Pore number x 100 (µµµµm -2) 5 % SiC, CP 25 % SiC, CP 20 % SiC, HP v=20 K/min v=30 K/min Ni Ni Cu (a) (b) Fig. 2.

A large number of research indicate that basic oxygen furnace slag (BOFS), as an active additive, may be used to prepare high performance cementitious material [3, 4], and it possibly becomes an important approach of high effect recovery utilization of steel slag in the future.
For every granularity grade, the number of measured BOFS particle was not less than 500 to ensure the stability and accuracy of measuring results. 4) According to the following formula, statistical average value of RLB of steel slag granules in the same granularity grade was calculated to explore the relationship between sphericity and granularity of granule.
where, n is the number of measured granules; RLBi is the RLB value of single granule.

In the future, we should focus on the stimulation of potential cementitious activity of BOFS and the optimization of its grain size distribution, etc.

The number of potentially dangerous equipment that has completed its established operational time, but is still being used, is permanently increasing.
The uniform boundaries of dislocations in the volume of a ferrite grain create sub-boundaries.
At investigation of the dislocation structure of neutral layers of an elbow metal the great number of micro-pores and dislocation near carbides were determined (Fig. 3 d).
This great number of micro-pores in neutral layers of an elbow metal is formed at the combined stress, which appears because of an oval of an elbow and a diffusion of vacancies while it is being maintained.
Definition of ultimate amplitudes of the relative elastic stress [σaF] or ultimate number of cycles [Nа] is carried out in view of reliability criterions (a rigid loading) (Fig. 7).

For highly elastic anisotropic metals, applied loads will cause stress concentration at the grain boundaries and at the triple junctions, which can lead to brittle failure [8, 9].
In addition, since different crystal structures have different symmetry, the number of independent elastic constants for different crystal structures is also different.
