二项式方程

Since conventional binominal and exponential deliverability equations ignore the effect of stress sensitivity, the open flow potential calculated by it is always bigger than actual value.

常规二项式和指数式产能方程忽略了应力敏感的影响，计算的无阻流量一般大于实际值。

It is shown by the calculation result of the well Heba1 deliverability that the open flow potential by pseudo pressure binominal exponential deliverability taking stress sensitivity into consideration is more coincidence with the actual, which is of reference in developing such gas reservoir with high pressure.

河坝1井的产能计算结果表明，考虑应力敏感的拟压力二项式产能方程所计算的无阻流量更加符合实际，对于开发类似高压气藏具有一定的参考意义。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
