本文应用扩展的卡尔曼滤波估计结构动态参数，文中提出一种简便的减缩变量卡尔曼游波方法，采用等效线性化原理识别结构的非线性参数。
A reduced Kalman filter method for estimating the dynamic parameters of structures is presented in the paper. The results of calculation and test show that this method is effective.
天渐渐黑了。小鱼小虾都忙着钻进石头缝里、海藻丛里、沙子里睡觉了。但是小海鬼波迪却还在四处游着。
It was getting dark. Fish shrimp are busy drilling rock crevices, algae bushes, the sand bed. But the small sea ghost Bodi still swimming in four.
这样能量会像波频一样游遍身体中的各个经脉，直达大脑。
Then the energies move like wave frequencies throughout the channels within the physical structure, moving right up to the brain.
虽然我游好波是如此强烈，我对石头虚线这样的力量，它留给我懵了。
Though I swam well the waves were so strong that I was dashed against a rock with such force that it left me senseless.
虽然我游好波是如此强烈，我对石头虚线这样的力量，它留给我懵了。
Though I swam well the waves were so strong that I was dashed against a rock with such force that it left me senseless.
