Because the exploration difficulty increased, the reserve accreting velocity was obviously slowed down and there was a rapid drop in the reserveproduction ratio.
但由于勘探难度增大，使储量增长速度明显放慢，储采比快速下降，若无新的发现，将无法保证长期高产稳产。

Therefore, it is of great significance to study the reserveproduction ratio and establish the relationship between the reserveproduction ratio and the decline rate.
因此，研究储采比并建立储采比与递减率之间关系具有重要的意义。

The Federal Reserve policy makers noted a continuing1 drop in sales and production. Their decision to lower the cost of borrowing money was not expected at this time.
