The study has focused on: 1 The research background and the current state of the power measurement were analyzed systematically, and then wavelet-based power measurement algorithm was certified feasible for astable signals; 2 We developed a new method of RMS and power measurement based on Dmeyer wavelet.

Firstly, this paper investigated roundly the basic theory of the ambient vibration method, analyzed systematically the main methods of ambient vibration identification, and discussed their advantages and disadvantages. Then we established the finite element model of structural dynamics and test model and analyzed their mutual relation, improved MUSIC method and correlation function method in the harmonic identification, and gave the subspace method and correlation function method based on continuous model, which is multi-harmonic retrieve technique. And then, this paper also puts forward least-squares method to estimate directly structural physical and modal parameters; this approach replaced the derivative operator in the continuous time model with an equivalent approximation, and estimated the physical parameters of structures by the least-squares method. And then, we discussed the approximation methods of derivative and their convergence. Finally, this paper researched the modal parameters of a frame structure by the simulation and test. The results demonstrated that subspace method, correlation function method and the least-squares method are effective and stable respectively.

和女儿聊天可以得到钢琴键，然后往左走，跳下去可得盔甲，如果不跳下去继续往左走就打BOSS，此怪重点在他会变色，用相应颜色的魔法才能打到它，打完以后得到风管，同时城堡礼拜堂左边的门打开了，继续前进，进入右边岔路部分后，先到下面的门，再走到最下面，右边第一场景往上跳，最右边破墙可以得到320个矿石，然后就可以回到岔路了，往上走可以遇到司教，和他说话可以得只有下水道，途中宝箱是250个矿石，最后走右边的门，这里的路有假，带上老太太给的鬼火宝珠，可以看到真实道路，往跳下可得盾牌，最右边就是BOSS，是一只狼，注意多跑动，打完BOSS，得到十字徽章，现在去城堡礼拜堂了

Fluxgate sensor inducts the environment magnetic field, outputs the compass course signal to the CPU system. This signal then is transformed into digital signal. CPU processes it and then gains compass course. When use rotary mathod to measure the deviations, CPU first collects timed the compass course come from the Fluxgate sensor, then calculates automatically their deviations and the correspondent coefficients. Based on all this, CPU can calculates out the real-time magnetic course or the real-time ture course, then sents them to display on the digital displayer.
