Unlike Wells designed to pump crude, oil sands don't have the same production decline rate.
Of this, State-owned and State holding enterprises reaped 152.6 billion yuan, showing a lower decline rate of 4.1 percent.
Comparably, the decline rate of the services is less than the manufacturing and probably revitalises in advance.
Therefore, it is of great significance to study the reserve production ratio and establish the relationship between the reserve production ratio and the decline rate.
Because the decline rate of oxygen saturation is certain, according to the change of numerical value, we can accurately calculate how long the patient's life is.
