If confirmed, this is an important result. It is in contrast with reports of significantly high offspring sex ratios in communities exposed to active seepages of natural gas and oil and to petrochemical a...

Natural gas station is an important part of the whole natural pipeline transmission system, in which vibration a hidden danger that cannot be ignored for safe operation station. In view severe enterprise, acceleration sensors are used to test each measuring point under different working conditions, and then three-dimensional finite element model established by using numerical simulation softwar...

In order to ensure the normal operation and personnel safety of energy storage station, this paper intends analyse potential failure mode identify risk through DFMEA analysis method, then targeted treatment items, formulate effective design prevention countermeasures emergency measures, so as improve station. The reliability battery can reduce safe
