Thus, the PFR was optimal for immobilized cells to produce L-malic acid in ammonium fumarate system.

因此，在富马酸铵体系中用固定化酶生产L-苹果酸采用填充床反应器更佳。

The ejection fraction (EF) and peak filling rate (PFR) were decreased and the time of peak filling rate (TPFR) was prolonged.

冠心病组射血分数、峰值充盈率减少，峰值充盈时间延长。

Plug flow reactor(PFR) and Continuous stirred tank reactor(CSTR) were studied to compare their performance for treating dairy manure.

对推流式反应器（PFR）和完全混合式反应器（CSTR）用于牛粪液厌氧消化的性能进行了比较研究。

NOTE: if you must remove any component and sent to workshop, print the PFR (Post Flight Report) and TDS (Trouble Shooting Data) (if existed), then attach printed documents on the part.

注：如果有部件要拆下送修，打印相关的PF R(航后报告)和TDS(排故数据)(如有)，并将其附在所拆下的部件上。
