1·The effect of temperatures on endogenous respiration rate was significant.

而温度对比内源呼吸速率的影响十分显著。

2·There was low nitrogen removal rate (18.8%) by endogenous respiration without carbon sources added.

当不投加外部碳源时（内碳源），通过内源呼吸代谢作用进行反硝化效果最差，脱氮率仅有18.8%。

3·These conclusions provide a basis for endogenous respiration rate becoming a control parameter of SBR.

这些结论为呼吸速率成为SBR工艺的控制参数提供了基础。

4·The relation of MLSS between the endogenous respiration rate and the maximum respiration rate are investigated and compared respectively based on activated sludge process.

以活性污泥为研究对象，分别测定了内源呼吸速率及最大呼吸速率同污泥浓度的关系，并进行了比较。

5·The pectin esterase (PE) activity was not obviously associated with the firmness. The activity of PG changed in a certain degree with fluctuation respiration and endogenous ethylene level.

多聚半乳糖醛酸酶活性与呼吸强度和内源乙烯的变化趋势较为一致，而果胶甲酯酶活性在整个贮藏期中由高到低变化较为平缓。
