基于激光除锈轮廓特征,在进行电网设备除锈控制参数确定时,主要依托于单一的轮廓几何特征,导致除锈后表面粗糙度偏差较大。设计一种以轮廓几何特征融合为核心的参数自适应确定方法,根据激光除锈工作原理,建立激光除锈有限元模型。采用边界矩分析算法,提取电网设备除锈的多个轮廓几何特征;融合多个轮廓几何特征,设计基于融合特征的参数确定方法,有效选择各项控制参数;通过响应面分析,自适应确定电网设备激光除锈控制参数。实验结果表明:该方法可使除锈后表面粗糙度与目标表面粗糙度值之间偏差减小2.7μm,与其他激光除锈控制参数设置结果相比,除锈后表面粗糙度偏差降低了54.24%、63.51%。

Newly developed sintering aid Na5.6Cu1.2Sb10O29 (NCS) and lead-bismuth-free piezoceramics (Na0.5K0.44Li0.06) Nb0.95Sb0.05O3 (NKLNS) were prepared by the conventional solid state reaction. The effects of sintering aid NCS on the electrical properties of NKLNS were investigated. It was found that the addition of a proper amount of sintering aid NCS to NKLNS is effective not only on improving the density and the piezoelectric activity, but also on reducing the dielectric loss of NKLNS. The NKLNS doped with 0.4 mol% NCS has a piezoelectric constant d33 as high as 261pC/N and an electromechanical coupling factor k33 above 60%. These results show that NCS-doped NKLNS is a promising and practicable candidate for lead-bismuth-free piezoceramics.

OBJECTIVE To investigate the advantages of applying microdebrider re- moval of juvenile-onset recurrent respiratory papillary epithelioma (JO- RRP), using an endoscopy-assisted prop-up laryngoscope. METHODS The degree of severity of the neoplasms was divided into 3 scores (i.e. 1 point for a slight degree, 2 points for a moderate and 3 points for a severe degree). The involvement of 22 respiratory and diges- tive sub-areas was evaluated and the total accumulative scoring and the scores for the lesions in the vocal area were calculated and sub - grouped. All the papillary epitheliomas were excised using a laryngeal micro-debrider or the micro laryngeal forceps under endoscopy-assist- ed suspension laryngoscopy. The differences between applications of the two modes of treatment for the cases of the groups with same scoring were compared as follows: the operation time, interval of operation, recent vocal quality after operation, postoperative scarring and incision of the trachea, as well as the distribution of tumors in a re-operation. REsuLTS The 142 operative procedures were performed in 33 pediatric patients, with application of a laryngeal microdebrider in 14 cases and ex- cision in 19. Compared to the excision group (EG), the laryngeal mi- crodebrider group (MDG) displayed many superior features, such as a short operation time, long interval between operations, obvious improve- ment in vocal quality soon after operation, and a low frequency of subse- quent tumors. There was a significant difference between these modes of the operation. A postoperative incision of the trachea was required in 2 cases of EG, whereas no post-operation was needed in the MDG. CONCLUSION There are many advantages in using laryngeal micro-de- brider removal of JO -RRP. The procedure is simple and convenient, having a distinct operating field, precise incision, minor wounds, fewer complications and better vocal quality soon after operation, as well as quicker rehabilitation and longer inte
