采用沉积法，以甲醇、丙酮为溶剂，AP为主要原料，对超细硼粉进行包覆。
The superfine boron powder was coated by aggradation method with AP using methanol or acetone as the solvent.
顶部超覆是无沉积作用间断的证据。
低渗透性的沉积物在快速沉降过程中 ，上覆岩层产生的不均衡压实可产生相当大的超压 ，这是沉积盆地形成高压的主要机制。
Overpressure mechanism is researched from the aspects of compaction disequilibrium, hydrocarbon generation and rock salt sealing according to the geophysical and geochemical data.
