对于大跨斜拉桥（润扬长江大桥北汉斜拉桥）的1024维频响函数可以仅用27个（或17个）主元来提取其主要特征，精度可满足工程需要。
Based on the anisotropy of magnetic susceptibility ( ams ) , the hannuoba basalt was probably originated from two volcanoes that locate in the northeast and north - northwest directions , respectively which is consistent with the field observation
基于磁化率各向异性测定，推断张北汉诺坝玄武岩是由位于北东和北北西两个方向的古火山口喷发而成，这与野外观察一致。
The dynamic behavior of a long span cable - stayed bridge ( north bridge of runyang yangtse river bridge ) is calculated , the frequency response function ( frf ) is compressed using principal component analysis ( pca ) , and the frf is then reconstructed based on a few , principal components
摘要针对润扬长江大桥北汉斜拉桥进行动力分析，采用主元分析对其频响函数进行了有效降维，并根据降维后的主元重构了结构频响。
