From the Valerio Cozzani’s and Khan’s research and analysis of past accident evidences, domino effects can be triggered by main types of primary events (accidents): fire (jet fire, pool fire, flash fire), VCE, BLEVE, Fireball, Mechanical explosion.
Domino effect is subject to different factors, the most important factors include: types of the failure equipment, hazardous substances and types of storage, the effected equipment and its properties, the distance from the accident point, the accident conditions (such as the ignition source), wind direction and the safety measures.
meant the distance from the failure equipment (primary event) to the adjacent equipment (affected event caused by domino effect) (1≤, ≤N).

The high energy ion beam irradiation of polymer is a sensitive technique to enhance its electrical conductivity, structural, mechanical and optical properties.
Electrical properties (I-V) were measured by four probe method.
It may be due to the higher rate of electronic energy loss of swift heavy ions, which affects the optical properties of polymers to a greater extent.

Based on this, the mechanical model is established and the property of stress distribution of the coal floor is analyzed, which explains the impact of water inrush.
Analysis of mining stress on coal floor After coal mining, in-situ rock mass stress field round the stope is affected by mining.
According to the characteristics of abutment pressure, the calculation simplified mechanical model is established, as shown in Fig.1.

The work reported here concentrates on resolving the energy consumption, consumables, low production efficiency of ring production, provided some reference for the rings production. 1 Introduction The traditional production of rings was alloy smelting, steel ingot casting, steel ingot cogging and forging, initial forging, punching, cutting, hot rolling forming, heat treatment process was generally taken to improve the material mechanical properties.
If directly use this ring in the hot rolling, there will be a serious hot crack which affect the quality of work-piece.

The mechanical properties of indicators higher than the standard values, it can be seen that rolling performance meet the standard requirements, which can be used to guide production. 3 Conclusions This contribution has described the process of ring product, the rings are large thick wall casting, The process of casting-rolling continuously forming was smelting casting→ ring blank→ concurrent heating and heat holding →hot rolling forming, the key process is to use waste heat directly on the hot rolling.
The mechanical properties of ring in casting-rolling continuously forming was above the standard of bearing ring, besides, it provided a reference for practical production.

In addition, an important factor that can hinder the use of laser shaping is the limited technological capabilities of the equipment.
Analysis of Publications The analysis of the factors [2] of the laser shaping process shows that the most influential of them are the following: the laser radiation power, the speed of movement of the laser beam, the size of the focusing zone, the thickness of the processed sample and the properties of the processed material.
The properties of the processed material are initial conditions, so we can change them only before the formation, for example, thermal, mechanical or other types of processing.
The choice of this steel is made in order to avoid influencing the results of formation of the mechanism of polymorphic transformations and, in general, structural changes in the processed material, which can significantly affect the formation results [8, 9].
A decrease in pitch between irradiated tracks leads to a decrease in the radius of curvature of the developed surface, while keeping all other factors stable.

A Fuzzy Control Simulation about Bearing Residual Magnetic Treatment ZHANG Fa-jun1,a, FANG Wen-jie1,b, ZHOU Chang1, LIU Zhong1 1School of Mechanical & Material Engineering of Three Gorges University, Yichang, China, 443002 adoctorzyy@126.com(corresponding author), bfangwenjie2011@163.com Key words: Bearing; Residual Magnetism; Fuzzy Control Abstract.
Bearing residual magnetism field always was partial point magnetic field, the maximum of these '"point" magnetic field were required to measure[3].Therefore, the size of residual magnetism value was related with the measured distance when measuring bearing residual magnetism, generally the near the distance between detection probe and bearing, the large the average inductive value, so in order to ensure the better control effect of demagnetization, it was selected the size of detection distance as another control input variable in the control input factors.
output factor, it was expressed as U.

According to fuzzy set theory, three variable factors were conducted with fuzzy subset division definition and treatment.

Nevertheless it has been shown that these cracks do not propagate into the substrate on exposure to steam at 650º C [5] and that the coating does not affect significantly the creep and the thermo-mechanical fatigue behavior of the substrate [15].
This estimation does not take into account possible failures caused by other factors such as spalling due to Kirkendall porosity.
It has also been shown that differences in substrate composition affect the coating morphology and may affect the coating degradation mechanism as well as its durability [14].
Therefore, the amount of N dissolved in the ferritic steel for strengthening purposes decreases and therefore may be expected to affect the mechanical properties of the alloy.
None of these effects seem to affect the coatings resistance to steam oxidation after more than 45,000 h of laboratory testing at 650º C [16].
