采用连续高功率固体NdYAG激光辐照,使预置于NiTi合金表面的Ti粉在N2环境中形成TiN增强Ti基复合材料涂层。选择适当的激光辐照工艺参数,获得致密的TiN增强金属基复合材料激光改性层。SEM观察及EDAX成分分析结果表明,TiN/Ti金属基复合材料表面改性层与基体NiTi合金存在良好的冶金结合,界面处成分均匀过渡,表面Ni含量极低。显微硬度测试及磨损实验表明,TiN/Ti金属基复合材料改性层显著提高了NiTi合金的表面硬度和耐磨性,激光表面改性层可有效地改善NiTi合金作为生物医学材料使用的表面成分和性能。

目的了解早产儿学龄前的睡眠特点,为早产儿干预措施的建立提供依据。方法采用多中心回顾性队列研究的方法,根据自愿原则,自2017年3月至2018年11月从广州、中山、深圳3家医院病案系统筛选202名4~6岁儿童,其中早中期早产儿(胎龄<34周)40名、晚期早产儿(胎龄34~36周)56名、足月儿106名(胎龄≥37周)。问卷包括儿童基本情况调查表及儿童睡眠习惯问卷中文版。结果相比于足月组,早中期早产组的夜间睡眠时间较短[(9.07±0.75)(9.33±0.59)h,β=-0.33],日均总睡眠时间较短[(10.39±0.86)(11.05±1.32)h,β=-0.70],睡眠持续得分较高[(4.60±1.57)(3.97±1.25)分,β=0.58],睡眠呼吸障碍得分较高[(3.78±1.27)(3.41±0.71)分,β=0.49];晚期早产组的异态睡眠得分较低[(8.40±1.65)(8.75±1.72)分,β=-0.57],差异均有统计学意义(P值均<0.05)。胎龄对学龄前儿童的日均总睡眠时间有正向预测作用(β=0.06),胎龄越大的学龄前儿童日均总睡眠时间越长;胎龄对睡眠呼吸障碍得分有负向预测作用(β=-0.06),胎龄越大的学龄前儿童睡眠呼吸障碍问题越少。结论早中期早产儿睡眠问题较多,主要为睡眠持续和睡眠呼吸障碍问题。应关注早中期早产儿的睡眠问题。

An amorphous magnetic material system(Co20Fe47Ta20B13)1-xOx is fabricated by magneto sputtering. Three stages of magnetization behavior exist when oxygen content changes in the system. As the oxygen increases, the absence of percolation effect of magnetic nano-particles makes the multi-domain structure broken so that high coercivity appears in the samples with proper oxygen content. A temperature-dependent Stoner–Wohlfarth model is used to explain the magnetization properties at relatively high temperature. Magnetizations with magnetic field in and out of the sample plane are also investigated to prove the mechanisms. This work provides a systematic study of a new kind ofv amorphous magnetic system and is helpful for us to know more about this type of material.

A pure dielectric metamaterial absorber with broadband and thin thickness is proposed,whose structure is designed as a periodic cross-hole *** pure dielectric metamaterial absorber with high permittivity is prepared by ceramic reinforced polymer *** with those with low permittivity,the absorber with high permittivity is more sensitive to structural parameters,which means that it is easier to optimize the equivalent electromagnetic parameters and achieve wide impedance matching by altering the size or shape of the unit *** optimized metamaterial absorber exhibits reflection loss below-10 dB in 7.93 GHz–35.76 GHz with a thickness of 3.5 mm,which shows favorable absorption properties under the oblique incidence of TE polarization(±45°).Whether it is a measured or simulated value,the strongest absorbing peak reaches below-45 dB,which exceeds that of most metamaterial *** distributions of power loss density and electric and magnetic fields are investigated to study the origin of their strong absorbing *** resonance mechanisms are proposed to explain the phenomenon,including polarization relaxation of the dielectric and edge effects of the cross-hole *** work overcomes the shortcomings of the narrow absorbing bandwidth of *** demonstrates that the pure dielectric metamaterial absorber with high permittivity has great potential in the field of microwave absorption.
