expl.	While a high powder factor may generate higher levels of vibration, noise and flyrock, a power factor that is too low may cause a blast to fail and may generate more vibration than expected for the charge per delay that was used, because of increased burden and confinement	当炸药威力大、产生的震感强、噪声大、飞石多。如果炸药威力太小、由于抵抗线和围压增加、会导致爆破失败、而且对于每次延时所用的药量而言、所产生的振动会比预计的要大
