| 1 | Microstructure and Tribological Behavior of Al2O3 Particle Reinforced Al Matrix Composites Fabricated by Spark Plasma Sintering显示文摘Nanoparticles and microparticles reinforced Al matrix composites were fabricated by spark plasma sintering, and the microstructure and tribological properties were investigated systemically. The nano-Al2O3 particle and micro-Al2O3 particle uniformly dispersed in Al matrix composites. The introduction of nanoparticles is beneficial to the decrease of friction coefficient and wear rate, while microparticles are responsible to the high friction coefficient, resulting in the abrasive wear. With the introduction of both nanoparticles and microparticles, their synergic effect will lead to the variation of tribological behavior. | 杨坤 AN Linan CHENG Laifei | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，5： | 2 |

| 4 | Ceramic Nanocomposites Reinforced with a High Volume Fraction of Carbon Nanotubes显示文摘Multi-walled carbon nanotubes(MWNTs) were incorporated into precursor-derived ceramics made from a polysilazane.A ceramic nanocomposite reinforced with about 35 vol%of carbon nanotubes(CNTs)was fabricated by infiltrating CNT-preform with liquid-phased polymeric precursor followed by pyrolysis.The nanocomposite has a dense structure without micro-cracks.The results reveal that the nanocomposite has lower indentation hardness but higher fracture energy than non-reinforced ceramic from the microindentation tests results.The effect of the CNTs on the mechanical properties of the nanocomposite should be discussed accordingly. | 杨坤 CHENG Laifei AN Linan SHAO Gang | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，1： | 1 |
| 5 | Report from 24 hours reproductive health hotline in Shanghai:a preliminary analysis on first 9 months hotline data显示文摘Objectives: To study reproductive health needs of Shanghai people, and to develop appropriate measures to meet their needs.Methods: Statistical analysis of 24 hours reproductive health hotline data 4,000 random sampled sex questions, comparing answers from differen t gender and different questions (sex questions vs other non-sex questions).Results: During the first 9 months a total of 44,216 calls wer e received by medical staff. The callers included various age groups (aged 12-7 8), different marital status, from Shanghai and outside. In total, the numbers o f men and women on hotline calls were almost same. The contents of the hotline c ounseling covered all aspects of reproductive health care; among them, the issue concerning male and female sex problems and prenatal and infant health care con stituted 26.5% and 34% respectively. Men asked questions about sex more frequent ly than women, whereas women asked questions more about baby care. Questions a bout sex problems were asked more often in the late evening until next early mor ning. Conclusions: Shanghai people showed higher needs in sexual heal th care, prenatal care and baby care. When they came across some related problem s or confusions, they would like to receive the professional instant counseling. Relevant health care programmes should be established in order to meet the fer tile-aged public's reproductive health needs. | Hu Xiaoyu(胡晓宇) Tong Chuanliang(童传良) Chen Junling(陈军玲) Xiao Zhiqin(肖志琴) Cheng Linan(程利南) | 2002 | 生殖医学杂志2002，11，z1： | 0 |
