For the purpose of solid waste co-disposal and heavy metal stabilization,foam glass-ceramics were produced by using municipal solid waste incineration(MWSI)bottom ash and fly ash as main raw materials,calcium carbonate(CaCO3) as foamer and sodium phosphate(Na3PO4) as foam *** influences of the raw material composition,foaming temperature and foaming time on the properties were ***,bulk density,mechanical property and leaching of heavy metals were analyzed *** product,foamed at 1150℃ for 30 min with 14% fly ash and 74% bottom ash,exhibits excellent comprehensive properties,such as high porosity(76.03%),low bulk density(0.67 g·cm-3) and high compressive strength(10.56 MPa).Moreover,the amount of leaching heavy metals,including Cr,Pb,Cu,Cd and Ni,in foam glass-ceramics is significantly lower than that of the US EPA hazardous waste *** study not only realizes the integrated utilization of bottom ash and fly ash,but also addresses a new strategy for obtaining foam glass-ceramics.

It was found that typical Nbss /Nb5Si3 eutectic lamellar structure formed in the Nb-Mo-Si alloy. The interface between Nbss and Nb5Si3 phases was so strong that the alloy fractured mainly in the cleavage mode. In this paper, the fourth element was added with the aim of modifying interface structure. The microstructural characterization and the fracture toughness of Nb-17Si-10Mo ternary alloy doped with Ga, In, Zn and V, respectively, were investigated. It was revealed that the lamellar structure maintained with the addition of Ga and In, whereas it changed slightly with Zn and V additions. Moreover, a little increase in fracture toughness of Nb-17Si-10Mo ternary alloy was obtained through the addition of Ga and Zn.

Glass-ceramics have been prepared by using stainless steel slag, fly ash and coal fly ash that were figobtained from industrial solid waste. The crystallization behavior and mechanical characterization of the glass-ce-ramics with different （CaO ＋ MgO）/（SiO2 ＋ Al2O3） content ratios were studied. While the basicity decreases from 1.2 to 0.9 cm^-3, the bridge oxygen content increases from 1.18 ~ 10^21 to 1.34 ~ 10^21 cm^-3. According to the deconvolution of Raman spectra, the relative abundance of the stretching of Si-Onb bond （Q^n units） can be obtained. The increase in the Q^3 units dominates the polymerization in the process of decreasing basicity. This change in bonding is demonstrated to lead to polymerization of the glass network and the increase in crystallization activation energy from 336.0 to 360.7 kJ·mol^-l. The results demonstrate that the production of the glass-ceramics from industrial steel slag, fly ash and coal fly ash is cost-effective and offers advantages over other production methods.

Background： Nowadays, social media tools such as short message service, Twitter, video, and web-based systems are more and more used in clinical follow-up, making clinical follow-up much more time- and cost-effective than ever before. However, as the most popular social media in China, little is known about the utility of smartphone WeChat application in follow-up. In this study, we aimed to investigate the feasibility and superiority of WeChat application in clinical follow-up. Methods： A total of 108 patients diagnosed with head and neck tumor were randomized to WeChat follow-up （WFU） group or telephone follow-up （TFU） group for 6-month follow-up. The follow-ups were delivered by WeChat or telephone at 2 weeks, 1, 2, 3, and 6 months to the patients after being discharged. The study measurements were time consumption for follow-up delivery, total economic cost, lost-to-follow-up rate, and overall satisfaction for the follow-up method. Results： Time consumption in WFU group for each patient （23.36 ± 6.16 min） was significantly shorter than that in TFU group （42.89 ± 7.15 min）（P 〈 0.001 ）; total economic cost in WFU group （RMB 90 Yuan） was much lower than that in TFU group （RMB 196 Yuan）. Lost-to-follow-up rate in the WFU group was 7.02% （4/57） compared with TFU group, 9.80% （5/51 ）, while no significance was observed （95% confidence interval [CI]： 0.176-2.740; P = 0.732）. The overall satisfaction rate in WFU group was 94.34% （50/53） compared with 80.43% （37/46） in TFU group （95% CI： 0.057-0.067; P = 0.034）. Conclusions： The smartphone WeChat application was found to be a viable option for follow-up in discharged patients with head and neck tumors. WFU was time-effective, cost-effective, and convenient in communication. This doctor-led follow-up model has the potential to establish a good physician-patient relationship by enhancing dynamic communications and providing individual health instructions.

通过在涡轮级进口周向上设置周期性总温分布,将转静干涉以及进口温度不均匀分布对声场的影响分离到各个周向模态上。通过均匀进口熵条件以及非均匀进口熵条件下的两个算例进行比较,直观的得出涡轮进口非均匀熵对涡轮转子后的声场的影响。算例结果表明:在只受周期进口总温分布影响的周向模态上,非均匀进口熵条件对声场的影响明显。相比均匀熵进口条件,非均匀熵进口条件下的总声功率级,一倍叶片通过频率下BPF增加约0.23 dB,二倍叶片通过频率增加约2.64 dB,通过数值方法验证了间接燃烧噪声。
