在行耳廓血管瘤剥脱手术的8例中有1例在分离结扎腮腺区血管时误伤面神经颈面干，术中行神经断端缝合，半年后面瘫基本消失。8例行剥脱术治疗耳廓血管瘤的患者经8个月至4年随访，除1例可见局限性血管隆起外，未见复发。

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。

Under the male-supremacy system in ancient western society, the marital rape in the criminal-law theory could undoubtedly have not a leg to stand on with the "male immunity" supported by "wife's commitment" and other arguments. Since the latter half of the 20th century, when a feminist movement for equal political, economic and sexual rights swept across western countries with an irresistible momentum in the on-going industrial revolution, people have begun to cast doubt upon the "male immunity" and write off the principle in the crime of rape.

古代西方在传统夫制社会下的男强女弱、男主女从的模式之下，刑法理论中的婚内强奸难以占得一席之地，主要缘于以"妻子承诺论"和"促使女方报复论"为理论支撑的"丈夫豁免"。20世纪中后期以来，在工业革命的背景下，西方各国开始了一场规模空前、势不可挡的以追求政治、经济、性权利平等为目标的女权运动，人们开始逐步反思检讨"丈夫豁免"的正当性，摒弃了强奸罪中的"丈夫除外"原则。
