In chapter 4, the Newlands harmonic wavelet is improved and a new type of wavelet with better time-frequency characteristic is constructed. Frequency band of signal can be divided arbitrary with the improved harmonic wavelet so that the phenomena of aliasing are reduced. Several typical fault signals in Electromechanical System are analyzed with it. In addition to the improved harmonic wavelet in chapter 4, a new half-complex wavelet is presented to improve the complex wavelet, which is given by Chaari.O. A unilateral recursive algorithm is derived to improve the real-time characteristic. A parameter n is imported to make the time-frequency and filtering characteristics of it better and its ability of extracting fault feature is enhanced.

第四章通过对Newland谐波小波的改进构造频域紧支撑、时域性能良好的新型小波函数，可实现信号频带的任意划分，从而减少频带混叠现象，采用改进的谐波小波对多种典型的机电系统故障信号进行了分析；以Chaari.O复小波为基础构造了一个半复小波，从提高复小波算法的实时性出发，推导了半复小波单向递推算法，通过给原小波设置可调参数的方法，实现了一种能满足小波基本条件的复值小波，可以通过参数的调整调节小波滤波器在Hilbert空间的时频特性和相应的滤波性能，以加强半复小波对故障特征的提取能力。

It is well established that Cav1.2 encoded L-type calcium channel is prevailing component in cardiac system, while Cav1.3 encoded one dominant expressed in neuron and neuroendocrine cell. However, our and others' previous works have shown that Cav1.3 encoded LTCC was also found in the heart tissues, especially in pacemaking cells of sina atrial node, atrioventricular node and atrium.

最初人们认为心脏中的 L 型钙通道仅包括α1C（Cav1.2），但后来发现α1D（Cav1.3）在心脏中也有表达，并且优势表达于窦房结、房室结和心房，加之发现它在比较低的膜电位（－60~50mv）激活而且α1D基因敲除小鼠表现出窦性心动过缓和房室传导阻滞，所有这些都表明α1D 在维持正常的心脏节律中发挥着至关重要的作用。
