We retrospectively evaluated the clinical outcome of penile prosthesis implantation （PPI） in Chinese patients with severe erectile dysfunction （SED）. From July 2000 to December 2011, 224 patients （mean age： 35.9±11.8 years, range： 20-75 years） with SED underwent PPI by experienced surgeon according to standard PPI procedure at our centre. A malleable prosthesis （AMS 650） was implanted in 45 cases （20.1%）, and a three-piece inflatable prosthesis （AMS 700 CXM or AMS 700 CXR） was implanted in 179 cases （79.9%）. Surgical outcomes, including postoperative complications, clinical efficacy and couple satisfaction, were evaluated over than 6 months postoperatively using medical record abstraction, IIEF-5, quality of life （QoL） scores, and the patient/partner sexual satisfaction score proposed by Bhojwani etaL Of the 224 patients eligible for the study, 201 subjects （89.7%） completed follow-up. All of patients could perform sexual intercourse post PPI with the mean postoperative IIEF-5 and QoL scores were 20.02±2.32 and 5.28±0.76, respectively, which were significantly improved compared with the preoperative scores （6.29±1.5 and 2.13±0.84, P〈0.01）. Of the 201 men, mechanical malfunction occurred in four cases （2.0%） and three cases were re-implanted new device, and two cases （1.0%） developed a mild curvature of the penis. Scrotal erosion with infection occurred in one case with diabetes mellitus （0.5%） and required complete removal of the implanted AMS 700 CXM. Satisfactory sexual intercourse at least twice per month was reported by 178 men （88.6%）, and overall satisfaction with the PPI surgery was reported by 89.0% of men and 82.5% of partners. Patient satisfaction in the three-piece inflatable prosthesis group was higher than in the malleable prosthesis group （P〈0.05）. Satisfaction, however, between the types of prostheses, did not differ in the partner survey. PPI is a safe and effective treatment option for Chinese patients with SED and experienced surgeon perform PPI ac

The ba-, La- and Ag-doped polycrystalline Ca2.9M0.1Co4O9 （M=Ca, ba, La, Ag） thermoelectric bulk samples were pre- pared via citrate acid sol-gel synthesis method followed by spark plasma sintering technique. The bulk samples were characterized and analyzed with regard to their phase compositions, grain orientations as well as microstructures. The high temperature thermoelec- tric transport properties of the bulk samples were studied in detail. All bulk samples were found to be single-phased with modified body texture. The electrical resistivity was modulated as a result of carrier concentration modification, however the carrier transport process was not influenced; the Seebeck coefficient was deteriorated simultaneously. The total thermal conductivity was remarkably reduced, on account of the decreasing of phonon thermal conductivity. The thermoelectric properties of the ba-, La-, and Ag-doped bulk samples were optimized, and the ba-doped Ca2.9ba0.1Co4O9 system was found to have the highest dimensionless figure of merit ZT0.20 at 973 K, which was remarkably higher than that of the un-doped sample.

The curve of the relation between fracture elongation and temperature for unltrafine grained low alloy hypoeutectoid steels generally shows that three peaks occur at temperatures just below A_ c1, between A_ c1 and A_ c3, and just above A_ c3, When these steels are subjected to superplastic tensile test at different temperatures, the value of the last one is the lowest and the other two peaks are different one from another depending on components, microstructures and deformation conditions of the steels.

Recently, the space bvp of real or complex numbers consisting of all sequences whose differences are in the space lp has been studied by basar, Altay [Ukrainian Math. J. 55（1）（2003）, 136-147], where 1 ≤ p ≤ ∞. The main purpose of the present paper is to introduce the space bvp（F） of sequences of p-bounded variation of fuzzy numbers. Moreover, it is proved that the space bvp（F） includes the space lp（F） and also shown that the spaces bvp（F） and lp（F） axe isomorphic for 1 ≤ p ≤∞. Furthermore, some inclusion relations have been given.

研究了在交变载荷作用下,化学镀液渗注到裂纹尖端的沉积行为对裂纹扩展速率的影响。用扫描电镜观察了化学沉积处理后裂纹面的形貌,并用能谱仪和X射线衍射仪对裂纹尖端镀层进行了成分和物相分析,最后将未处理试样与化学沉积处理过试样的裂纹扩展速率进行对比。结果表明:裂纹尖端发生了明显的镍磷合金的沉积行为,且在裂纹尖端进行化学沉积处理能有效降低裂纹扩展的速率。
