This paper proposes a non-linear adaptive filtering method based on analyzing the performance of the conventional adaptive methods in the cases of that the NBI can be modeled as a single tone,an autoregressive stochastic process or narrow band BPSK digital modulation signals.

在分析线性自适应滤波抑制单频干扰、自回归过程窄带干扰和窄带BPSK调制信号干扰的性能的基础上，提出了一种非线性自适应波抑制方法。

The AR spectrum is not restricted by length of data, and AR spectrum parameters are sensitive for law of condition change. Autoregressive transformation is made to vibration signals, and then AR spectrum coefficients are got which can be utilized as feature vectors. Fault diagnosis method for centrifugal pump Based on AR and 2D-HMM is produced in this paper. The topology of this model and its parameters were introduced too.

利用AR谱不受数据长度的限制，AR模型参数对状态变化规律反映敏感的特点，以振动信号做自回归变换后的AR谱系数作为特征向量，将基于AR的2D-HMM引入到离心泵故障诊断中，提出了一种基于AR的2D-HMM故障诊断方法，并论述了该模型的拓扑结构和主要参数以及相应的训练和识别算法。

Avoid using buffers containing sodium azide, which may quench HRP signals.

That Babette's infidelity was rooted in an uncontrollable fear of dying is especially important, since it signals the convergence of Jack's fear of dying and his fear of plots.

这芭贝特不忠是植根于一种无法控制的恐惧死亡是特别重要，因为它信号的收敛性杰克的恐惧的死亡和他的恐惧阴谋。

Experiment with vibration signals of ball bearing is conducted, which shows that this method has adequate classification ability.

这对于关键设备的在线状态监测和状态评估，具有重要的工程应用价值。

The wide bandwidth bandpass filter is designed to suppress the fundamental and third harmonic signals.

设计宽带带通滤波器的目的是为了抑制基波和三次谐波。

The pattern spectrum entropy and the barycenter scale location of the spectrum curve were used to input data to the support vector machine to identify different types of signals.The experimental...

答：很多时候，它表明一个人的真实感受，这可能是相反的实际上正在发言。

He said that the business department with its customers to exchange the results showed that, although this year to bear a greater loss, but they are still actively seeking opportunities to rebound, with the result of the exchange fund clients showed that some Consensus has been formed, the current stock price adjustment should be able to fully reflect the risks (for example, a negative growth in 2009 profits) as long as there is no hard landing for the economy, a growing number of stocks have begun to show the value of the investment, on the other hand, the economy and earnings are still In a clear downward trend, investment strategy on economic policies still need to wait for the stock market and policy signals the emergence of two major turning point, the majority of investors in 2400 have not yet reflect the sharp point of the will of the holdings; However, if the market continued to fall, the brave will not hesitate On the left side of the transaction provide us with the risk.

他说，与客户业务部门交流的结果显示，虽然今年承受更大的损失，但他们仍在积极寻求与外汇基金的客户端显示的结果反弹的机会，一些共识已经形成，目前的股价调整应能充分反映风险（例如，在2009年利润负增长），只要没有经济方面，越来越多的股票已经开始硬着陆显示另一方面的投资价值，经济和收入仍处于明显的下降趋势，对经济政策的投资策略仍然需要等待股市和政策信号的两个重要转折点，出现了大多数投资者在2400年还没有反映的控股公司将尖，但是，如果市场继续下跌，勇敢不会在交易左侧毫不犹豫地提供了我们的风险。
