Based on the gray static model, fracturedensity expression are worked out, and the calculated conclusion have higher precision.
用灰色静态模型建立起计算裂缝密度的表达式，计算结果精度较高。
2
The fracturedensity and their opening status controll the permeability and throughput of volcanic reservoirs and change along with the variation in lithology and lightfaces.
裂缝的密度和开启程度是渗流性和产能主控因素，其密度和充填程度随岩性岩相变化而变化。
3
Elastic parameter such as impedance, velocity, Poisson ratio etc. and pre-stack amplitude, frequency attributes can be used to quantitatively predict the fracturedensity and direction.
