PQD的翻译

Investigating the levels of lipid peroxidase ( LPO) and superoxide dismutase ( SOD) in serum, bronchoalveolar lavage fluid ( BALF) and alveolar macrophage ( AM) were determined in 40 chronic bronchitis patients with Pulmonary Qi Deficiency ( PQD) Syndrome and 36 normal subjects.

检测40例慢性支气管炎肺气虚证患者及36名健康人外周血、支气管肺灌洗液（BALF）中超氧化物歧化酶（SOD）、过氧化脂质（LPO）以及肺泡巨噬细胞（AM）内SOD含量。

A new classification method for power quality disturbance ( PQD) based on singular value ( SV) feature vectors of S-transform ( ST) time-frequency matrixes ( TFM) has been proposed.

提出了一种基于S变换时频矩阵奇异值特征向量的电能质量扰动分类方法。

Aimed at power quality disturbance ( PQD), several transformation-based analysis methods are introduced. By comparing those methods, a method is brought forward based on the wavelet packet ( WP) energy chart.

针对电能质量扰动问题，通过介绍几种基于变换理论的电能质量扰动检测和分类方法，对比分析各种方法之利弊，提出了基于小波包能量谱的电能质量短期扰动检测与分类新方法。
