查询词典 valid function

The two methods are presented for non-stationary leakage signals based on original feature gradate. One is a combination of the peak-peak and grads, the other is mean energy method, with the methods eliminate influence of noise and the stress concentration identification is improved. Based on the relativity for wavelet coefficient square, the signal singularity detection theory of wavelet transform was employed to determine metal magnetic memory. Experiment shows that the method is valid for leakage signal.

针对含有噪声非平稳性的漏磁信号，在原有信号特征量梯度的基础上，给出了新的时域空间梯度和峰-峰值组合特征量，以及能量峰值处理方法，有效消除了随机噪声对磁记忆信号的影响，提高了应力集中区的识别率；从磁记忆信号的奇异性检测角度出发，通过多尺度小波系数的平方相关一致性来确定真正的应力集中区；实验验证了所提方法的有效性。

First, the basic concept of VR and review of the present research method of architecture presentation are introduced, it proves that VR is necessary and reliable to represent architecture as a new method. Second, geometrical optimized method and texture optimized method are discussed specially, along with the analysis of characteristic of ancient and modern architectures. In the third part, the exhibition effect of optimized technique proved that the technique proposed in this dissertation is feasible and valid, which is applied in the Grand Leshan Buddha and Olympic Park separately.
