An on-line blind source separation algorithm of non-stationary mixed signals is presented. The algorithm uses the multiple time-delayed decorrelation and natural gradient rule to obtain the stationary point of the cost function, only a small number of observed samples is needed to minimize the Frobenius norm of the correlation matrices, so the computing cost is low and continuous separation calculation could be realized by on-line operation.

利用一种基于多时延解相关准则的代价函数和自然梯度原则，分别推导出非平稳信号在瞬态线性混合及卷积混合情况下的在线盲分离算法，仅通过对有限个时延样本的相关矩阵进行Frobenius范数最小化运算得到分离矩阵，计算工作量小，无需对样本进行分块处理，可实现对信号的连续跟踪操作。

Based on experimental results for conventional ultrasonic creeping wave,straight beam probe,small angle longitudinal wave,micro-paralleling creeping wave,an approach is proposed to select small angle longitudinal wave and micro-paralleling creeping wave to detect strut porcelain insulator.The choice of ultrasonic apparatus,probe and test block,the adjustment manner of working sensitivity and sweep speed,the principle of decision defect are presented.

在总结分析传统超声爬波法、横波法、普通直探头法、小角度纵波斜探头法和微型并联爬波法等几种常用的支柱瓷绝缘子超声波检测方法优缺点的基础上，通过试验分析了采用小角度纵波斜探头结合微型并联爬波探头对支柱瓷绝缘子进行超声波检测的工艺方法，确定了用该法对瓷绝缘子进行超声波检测的仪器、探头和试块的选用，探伤灵敏度和扫描速度的调整方法以及缺陷判定的原则。

Results:Under the laparoscopy,1 patient had a normal pelvis,the other 9 persons got conglutinant pelvis(7 were caused by chronic pelvic inflammation,1 by operation,1 by endometriosis),3 got wide conglutination between the back wall of uterus and rectum,depression of rectum disappeared;1 got pelvic inflammatory cyst;4 got endometriosis,and one of which got bilateral ovarian cyst and bilateral ovarian small teratoma.

结果：1例盆腔正常；9例盆腔粘连（慢性盆腔炎引起7例，手术引起1例，子宫内膜异位引起1例），其中3例子宫后壁与直肠广泛粘连，直肠窝消失；1例盆腔炎症包块；4例子宫内膜异位，其中1例双侧卵巢小巧克力囊肿合并双侧卵巢小畸胎瘤。

What arrived, however, were small pads of meat wrapped incrisp bacon, and little potatoes with their skins on, which had been rolled in hot butter and crisped in thepan.

可上来的却是脆熏猪肉包着的小肉块和拌着热黄油在锅里炸脆的带皮小马铃薯，还有微甜的胡萝卜条。

The results show that increasing the ball numbers and mandrel extension length may reduce the ovalization, but leads to more remarkable wall thinning; the ovalization becomes more severe with the larger bending angle; the smaller the relative bending radius, the larger the ovalization is; the ovalization and wall thinning degrees are both smaller in the case of pressure die with dry lubricant; and under the same bending condition, the ovalization of LF2M tube is larger than the one of 1Cr18Ni9Ti tube.

结果表明，增加芯头个数与芯棒伸长量都能减小弯管的截面畸变，但两者都导致弯管壁厚减薄量增大；随着弯曲角度的增加，截面畸变越严重，相对弯曲半径越小，无芯棒与芯头支撑段弯管的截面畸变愈严重；在压块无润滑情况下，弯管的截面畸变和壁厚减薄量都小，并且在同等弯曲条件下，1Cr18Ni9Ti弯管的截面畸变小于LF2M弯管。

The so-called wavelet coefficient block consists of those wavelet coefficients of an image that are only related to a local region of the image.

所谓小波系数块是指图像的部分小波系数，它们只与图像的某个局部相关。

Firstly, the proposed metric acquires the watermark embedded map based on the characteristics of human visual system. Then, the 3-level discrete wavelet decomposition is implemented, and the digital watermark is embedded into each wavelet coefficient block according to the watermark embedded map.

提出的方法首先结合人类视觉系统的特性检测原始图像的纹理丰富区域，获得水印嵌入指示图；然后将原始图像进行3层小波分解，根据水印嵌入指示图在每个小波系数块内利用量化的方法嵌入自定义水印；最后通过失真图像的水印复原率实现对图像的客观质量评价。
