The influence of the ambient temperature in engine room and the amount of engine room ventilation on the operation of marine main diesel engine was analyzed briefly, and the countermeasures of the start of cold engine and the engine precautions under extremely cold ambient temperature condition were introduced, for example,scavenge air bypass/blow-off and exhaust gas bypass.

Construction of virtual human in virtual environment of ship engine room;

Design method of engine room based on virtual reality technology;

Application of LabView for warning terminal of marine engine room;

Preliminary study on machinery room design of a 308 000 dwt VLCC based on CSR for Double Hull Oil Tankers;

Causes analysis and countermeasures on vessel's engine room fire;

0 were employed to study the engine room fire spreading, which to verify the validity of fire extinguishing by water mist.

In this experiment,the closure with a flexible panel was used to simulate the aircraft cabin; piezoelectric actuators and sensors were adhered to the flexible panel;as to signal treatment, this paper used VC++ to make main interface and MATLAB to do background analysis work; the signal of 100 Hz was chosed as noise source.
