Does JME support external particle effects file?if it does,have there any relevant examples that I can refer to? I’d like to refer to external particle effects file.

Do you mean some 3rd party particle software files? if so, then no. You can save jME particles in .j3o files however.

Well you can make jme use more or less any third party software, and write the missing link to the jme particle system yourself. So yes and no.
