Pum blossoms remain us of the beauty of the nature before spring sets in.

梅花让我们想起了春天来临之前大自然的美丽。

Tank elevation is to be approx. 3 meters above pum suction for NPSH requirements.

为满足NPSH要求，罐的标高应该大约位于泵进水口3米之上。

The analysis also shows that the intensity of parametric oscillation is a multi-valued function of the pum…

理论分析还指出，由于存在与泵浦强度有关的衰减系数，使参量振荡信号强度与泵浦强度呈多值关系。

The partition of unity method (PUM) and Level Set Method (LSM) are briefly introduced in sections 2 and 3, respectively.

第2和第3节分别简要介绍单位分解法和水平集法；

PUM is less expensive, lower management require and faster to implement than VERP, which is more in line with the actual management status of nature reserves.

经分析，PUM方法较VERP而言能够减少资金投入、缩短评估周期以及降低对管理者的要求，更符合我国自然保护区管理实际。
