衰減倍數 的英文怎麼說
中文拼音 [shuāijiǎnbèishǔ]
衰減倍數
英文
damping factot-
The influence of various waterpower and configuration parameters on heat transfer is analysed and the rules of convective heat transfer coefficient and the ratio of heat transfer enhancement with mass flux are obtained. at the same time, we gain important results as below : as for resonance chamber with certain configuration, self - oscillation can be generated under suitable configuration and waterpower parameters. for the same configuration resonance chamber, the intensity of the self - oscillation is changed by the waterpower parameters
當流量及壓差降低至一定程度時，共振腔還可能削弱換熱；加熱功率的提高會增加流體（水）的溫度，流體的粘度會隨著降低，這會減少對流體脈動的阻礙，使脈動衰減得更慢，而脈動幅度的增加會增強換熱，故加熱功率對有脈動的對流換熱是有影響的；自振腔產生的流體脈動頻率是自振腔固有頻率或其整數倍，流體脈動頻率過高或過低都不利於對流換熱，存在一有利於強化換熱的頻率范圍。A protection algorithm can be judged as having strong capability of anti interference if it can eliminate decaying direct current component and high harmonic whose frequency is not the integer times of system base - frequency
