| Abstract: | Aimed at the problem of electronechanical equipment in ship of vibrate threshold setting.I advanced the Bootstrap method for sample expansion.First,I made use of simulation experiment,based on two kind of usual sampling methods,for count this method’s effect and feasibility;second,I advanced third pairs of suggestions on application this method;Finally,in practice we applied this method in setting the threshold of vibrant intensity on a certain kind of diesel engine,and achieved a satisfactory result. |
