1·If this pressure reduction is enough to cause dissociation, then gas from the hydrate layer is released and can be extracted at the same time.

如果压降足以产生离解，则天然气将从水合物地层中释放出来，此时即可进行开采了。

2·Dissociation and ionization of air bring on lower drag coefficients of the orbiter than that obtained from perfect gas model, while the location of pressure center moves forward.

空气的离解和电离导致轨道器的阻力系数比完全气体计算值低，压心位置前移。

3·The dissociation rate is zero order with respect to its effective oxygen content, and is first order with respect to the water vapor pressure.

它的分解反应速率对有效氧含量是零级的，对水汽分压是一级的。

4·The influences of pressure, composition and the dissociation degree of CH3I on gain are investigated in detail.

研究了各种压力条件下成份比和CH_3I离解度对增益系数的影响。
