recurrent frequency 中文意思是什麼
recurrent frequency
解釋
重發頻率-
In the process of solving, poles are obtained from recurrent formula, modal vector are obtained from superposition formula not residuary. decoupled equation is derived when vibration source is part correlation, severely coupling appears in the process of input and output then frequency response function cannot directly get according to method mentioned above, decoupling is first problem
當輸入完全相關時，頻響函數無解，可繞過頻響函數，直接運用線性系統的迭加原理來求響應，極點由遞歸公式得出，模態矢量由疊加公式求出，而不是由留數求得的相應的公式。 -
The year of 2003 is in the declining phase of cyler 23 and the frequency of the solar - eruption is low, so the recurrent geomagnetic strom is dominant in all the geomagnetic activities
由於2003年處于太陽活動下降年，太陽爆發活動頻次減小，地磁活動主要以重現型地磁暴佔主導。 -
This feature perfectly combine the frequency in acoustics level and the temperament in music semantic level, we use the cosine distance of this feature to represent the similarity of two music clips, then we design a group of algorithms that is inspired from the thought of edit distance and dynamic programming. they segment the feature vectors into groups at first, then through group similarity match, group recurrent detect, merge recurrent group and structure label joined algorithms to complete the music structure label task. because this is a really new field of research and no good method of evaluation had been finding, we propose a new evaluation method and the results of the experiments show that it is a good method
然後設計了一組源於編輯距離和動態規劃思想的音樂結構分析演算法，首先將特徵向量分組，然後經過組相似匹配、組重現檢測、重現組歸並和自動標注四個前後銜接的環節實現了音樂結構的自動標注，較好地實現了將音頻形式的音樂自動標注為表示音樂結構的三元組列表形式，由於這是一個新的領域，目前還沒有比較好的量化評價方法，本文提出一種新的評價方法，並用它來評價結構分析的結果，取得了較好的效果。
