From the block diagram of operational reliability, the roller reliability is: (11) Assuming that the reliability of the left bearing is equal to the reliability of the right bearing and the reliability of the left sealing group is equal to the right sealing group, as they are made of the same materials, the reliability function from Eq. 11 can be rewritten as follows: (12) Fig. 6.
The reliability function for case (a) is: (13) Assuming that the reliability of the left internal sensor elements are equal to the right internal sensor elements, the reliability of the left rubber ring is equal to the right rubber ring, the reliability of the left push ring is equal to the right push ring, the reliability of the left sealing ring is equal to the right sealing ring and the reliability of the left ring is equal to the right ring, as they are made of the same materials, the reliability function from Eq. 13 may be rewritten as follows: (14) The reliability function for case (b) is: (15) Assuming that the reliability of the parts of the left and right sealing group are equal to the reliability function for the quasi-ordered connection of the sealing group, the reliability function of the roller reads: (16) Where, in the preceding expressions: - RUPL(t) = RUPD(t) = RUP(t) are the reliabilities of the left (UPL), right (UPD) and internal sensor elements

Introduction Soybeans are the most important legume [1] and have been used as beneficial dietary and nutritive materials in many counties because of their high quality protein and many other functional substances like phenolic acids and isoflavones. [2] Although SBM is rich in protein content, but the raw of SBM contains a variety of anti-nutritional factors (ANFs), including soybean antigen protein (sensitization factor), trypsin inhibitor and carbohydrates (such as a-galactosyl derivatives of sucrose and non-starch polysaccharides), etc. [3, 4] These ANFs will hinder the digestion, absorption and utilization of nutrients, further, which will adverse impact on the growth and health of the animals, especially young animals. [5] Previous research on FSBM mainly carried out using single strain to ferment soybean meal and there were some shortcomings, such as unstable quality, long fermentation period, etc.
Materials and methods 2.1 Soybean meal The SBM products were obtained from COFCO Eastocean Oils & Grains Industrial Co., Ltd.

Crystal growth control system block diagram Cadmium Zinc Tellurium Crystal Growth Principle By material science know CdZnTe Crystal melting point higher, its melting point values is in connection with CdZnTe three materials ratio; for example, Te Zn0.04 Cd0.96, Crystal melting point is 1095 ℃[1].
In order to guarantee that the tellurium zinc cadmium material interior elevation of temperature is even, the elevation of temperature process uses the curve control to make it to elevate temperature slowly.

An explosion is a chemical reaction that converts the initial material into a gas at an extremely high temperature and pressure; the process occurs with extreme rapidity and emits a substantial amount of heat.
The test cylinder was made of T6061-T6 aluminum (engineering properties of the material are given in Table 2).

The pre-heating beam intensity is tuned to make the treated material heated to a level just below the melting point.
Depending upon the type of alloy required at the surface, a less expensive base material can be locally modified to improve the resistance to corrosion, wear, and oxidation.

Two approaches are currently used to achieve low-k materials: (i) by reducing the polarisabilty of materials [2], this means use of materials with chemical bonds having a polarisability lower than Si-O one.
The IC industry already uses some low-k materials.
