Accessing particle system info?

How can I access the local velocity, min/max size, energy and emission of particle emitters through other scripts (ex: When var A>5 particle size =5, energy =2)?

Do you mean:

var curParicleEmitter : ParticleEmitter;

in your example above, instead of curTransform?

var curTransform : ParticleEmitter;
curParticleEmitter = gameObject.GetComponent(ParticleEmitter);
curParticleEmitter.minEnergy = 8;
