Firstly, it discusses the principle of adaptive interference chancellor, including broad band signal and narrow band signal; Secondly, it analysises one common algorithm used in adaptive interference chancellor, that is, LMS algorithm and its anamorphosis algorithm especially normalized LMS algorithm pointing out their relationship. After then, the paper talks about the structure and reality of canceling broad band noise in narrow band signal and narrow band noise in broad band signal and gives it's result simulation analyzing the factors affecting the power of the algorithm. In the last party, it gives the hardware design and assembly language software design using TMS32OC3 1, including the result of simulating.

首先，本文讨论了自适应干扰对消的原理，并对窄带信号和宽带信号两种进行了分别分析；然后本文对自适应干扰对消中常用的算法—LMS算法进行了分析，同时也讨论了LMS算法的变形算法，尤其是归一化LMS算法，并指出了这些算法的相同和不同之处；此后，本文讨论了窄带信号中的宽带干扰对消和宽带信号中的窄带干扰对消的结构及实现方法并给出了住址的结果，分析了影响干扰对消效果的因素；在论文的最后，给出了用TMS320C31实现窄带信号中的宽带干扰对消的硬件设计和汇编程序设计，以及汇编语言程序的结果，并就此结果与高级语言程序的结果作了比较。

Initial growths of disturbances are measured by means of hot-wire anemometry. Due to the detected signals with low signal to noise ratio, the coherence function is used to eliminate background noise during data reduction.

在扰动增长的初始阶段，信号的信噪比非常地低，根据相关谱分析方法，应用相干函数，将扰动信号有效地提取出来，测量了初始扰动的增长。

The comparison of the three noise values indicated that while the product of pulse width and angular frequency is larger than 1, the pulse width jitter would contribute considerable power to the total noise power spectrum, which is consistent well with the theoretical analysis.

比较三个噪声值表明了：在脉冲宽度角频率积Tω＞1的情况下，脉冲宽度抖动对总噪声量有较大贡献，脉冲宽度抖动不可忽略。

At last, the paper bring forward the restrain measure for not same noise, anticline scatter noise and the temperature change.

最后对干涉型光纤陀螺的误差机理进行了研究，提出了对光纤非互易性噪声、背向散射噪声和温度变化的抑制措施。

In accordance with the contradictory between the antinoise ability and detection accuracy, according to the characteristics that the noise is uncorrelation among different frequency channels and the signal has relatively more energy than the noise in each channel, the mutual-energy cross technique is proposed.

针对检测中抗噪能力和检测精度的矛盾，根据噪声在分解的每个频道间彼此互不相关，而信号相对噪声在每个频道却有较大能量的特点，提出了互能量交叉的噪声抑制方法。

It can be testified by experiments that the filters can attenuate both Gaussian noise and impulse noise.

实验结果表明，该算法对于高斯噪声和脉冲噪声都有很好的降噪能力。

Nevertheless,or exactly for that reason,it is the place that is still full of extreme neglect and even hostility toward the noise's aesthetic and political possibilities ,only the lives of every samll and minor activity that has its own aural qualities could not be accumulated and sustained here;the condition for listening to the sound of the collectives of the 'small poeple' and the 'tiny machines',under or maybe beyond the threshold of audibility ,dosesn't seem to be secured sufficiently.surely,this kind of problem is not confined in the particular locality like seoul,or south korea.anyway,this tension and the sense of the absence of condition,together,have been the main source of the two koren resident noise-making.

然而，或许更是因为，这是一个对噪音美学与政治的可能性充满轻蔑与敌视的地方，在这里，那些有自身听感氛围与质量的小众活动不能够集聚起来并很好的持续下去；对於那些倾心于此类音乐并集合在一起的"弱小个体"们和那些"微型机器"，必然是早就远离或超越了肤浅的旋律性和可听性的门槛，看起来并不能稳定地被安置，当然，此类问题不只被局限在一个小的局部，首尔，韩国，无论在哪，这一切产生的张力连同其状况本身，反复地显现在我们眼前，交织在一起，构成了两个韩国人创作原生噪音的来源。

Metrorrhagia is also gynaecological problems of common diseases.
