Objective： Population-based cancer registration data in 2012 from all available cancer registries in Shandong province were collected by Shandong Center for Disease Control and Prevention （SDCDC）. SDCDC estimated the numbers of new cancer eases and cancer deaths in Shandong province with compiled cancer incidence and mortality rates. Methods： In 2015, there were 21 cancer registries submitted data of cancer incidence and deaths occurred in 2012. All the data were checked and evaluated based on the National Central Cancer Registry （NCCR） criteria of data quality. Qualified data from 15 registries were used for cancer statisties analysis as provincial estimation. The pooled data were stratified by area （urban/rural）, gender, age group （0, 1-4, 5-9, 10-14, ..., 85＋ years） and cancer type. New cancer cases and deaths were estimated using age-specific rates and corresponding provincial population in 2012. The Chinese census data in 2000 and Segi＇s population were applied for age-standardized rates. All the rates were expressed per 100,000 person-year. Results： Qualified 15 cancer registries （4 urban and 11 rural registries） covered 17,189,988 populations （7,486,039 in urban and 9,703,949 in rural areas）. The percentage of cases morphologically verified （MV%） and death certificate-only cases （DCO%） were 66.12% and 2.93%, respectively, and the mortality to incidence rate ratio （M/I） was 0.60. A total of 253,060 new cancer cases and 157,750 cancer deaths were estimated in Shandong province in 2012. The incidence rate was 263.86/100,000 （303.29/100,000 in males, 223.23/100,000 in females）, the age-standardized incidence rates by Chinese standard population （ASIRC） and by world standard population （ASIRW） were 192.42/100,000 and 189.50/100,000 with the cumulative incidence rate （0-74 years old） of 22.07%. The cancer incidence, ASIRC and ASIRW in urban areas were 267.64/100,000, 195.27/100,000 and 192.02/100,000 compared to 262.32/100,000, 191.26/100,000 and 188.48/100,000 in

The AIN particle reinforced aluminum matrix composites with 50% volume fraction were fabricated by squeeze-casting technology. The thermal expansion behavior and its response to thermal cycling were studied between 20℃ and 400℃. Compared with four theoretical models, the measured CTEs of the composite lie within the elastic bounds derived by Schapery’s analysis. Schapery’s model and Kerner’s model agree well with the CTEs of the composites at lower temperature and elevated temperature, respectively. Strain hysteresis was observed between heating and cooling curves during cycling. This was attributed primarily to the anelastic behavior of the matrix induced by matrix residual stresses.

石墨烯具有明显优于传统高性能材料(例如陶瓷颗粒、碳纤维和碳纳米管等)的极高的弹性模量(高于1000GPa)、断裂强度(高于120GPa)和优异的导热性能(约5300 W/(m·K))[1],因此石墨烯一直被视为一种理想的复合材料的增强材料,这也是石墨烯的一个非常重要的应用领域。另一方面,作为增强体材料,陶瓷颗粒[2]、碳纤维[3]和碳纳米管[4]等已在铝基复合材料中大量研究;但是石墨烯或者石墨烯纳米微片(GNPs)增强的铝基复合材料的研究还刚刚起步[5-7]。目前文献中报导的制备石墨烯/Al(包括GNPs/Al)复合材料的方法主要为固态法(使用最多的方法为粉末冶金法)[8-10],而采用液态法制备的石墨烯/Al复合材料的研究尚未见文献报导。本文在前期研究工作基础上,利用压力浸渗专业技术制备了工业级石墨烯纳米微片增强的Al-20Si(GNFs/Al-20Si)复合材料,并研究了石墨烯纳米微片对复合材料显微组织与性能的影响。研究结果表明,石墨烯纳米微片的强化效果非常明显,同时液态法也是可以制备石墨烯/Al复合材料的一种有效方法。

Hexagonal microtube ZnO was firstly grown on single crystal p-Si (111) substrates by hydrothermal method, and fabricated Ag/n-ZnO and Au/n-ZnO Schottky junction. Schottky effective barrier heights were calculated by I-V measurement. It is confirmed that the presence of a large amount of surface states related possibly to lattice imperfections existed near the surface leads to the pinning of the surface Fermi level at 0.35eV below the conduction-band edge. Then the fabricated Schottky barrier junctions are evaluated for their use as UV photodetectors.

The in situ reaction procedure and microstructure evolution of a graphite fiber reinforced Ti-Al composite （Grf/Ti-Al） was investigated, and the stability of TiAl3 at high temperature was discussed. As-cast material was prepared by pressing molten pure aluminum into a preform, which was composed of titanium particles and graphite fibers. The in situ reaction procedure of the as-cast material was investigated by differential scanning calorimetry （DSC）, and phases in the products were detected by X-ray diffraction （XRD）. Experimental results showed that TiAl3 was formed first. With an increase in temperature, TiC and Al4C3 were observed, but TiAl3 decreased. In the final product, Al2O3 and TiO2 were observed. It was considered that the previous forming TiAl3 decomposed, then TiC precipitated, and subsequently, oxidation resulted in the formation of Al2O3 and TiO2.

以环塔里木盆地阿克苏、喀什、和田及巴州4个地区红枣园为研究对象,测定0~20、20~40、40~60 cm土壤有机碳(SOC)、全氮(TN)、全磷(TP)含量并分析其化学计量比。结果表明,果园土壤SOC、TN、TP含量及其化学计量比除TP含量和C∶N外均低于中国土壤平均水平。0~60 cm土壤SOC、TN含量及C∶P、N∶P均表现为阿克苏地区最高,和田地区最低;土壤TP含量表现为阿克苏地区最高,巴州地区最低;C∶N表现为巴州地区最高,喀什地区最低。随土层深度的增加,4个地区土壤SOC、TN、TP含量及C∶P、N∶P均降低;除和田地区外,其他地区土壤C∶N均随土层深度的增加而升高。冗余分析结果表明,果园土壤SOC、TN、TP含量及其化学计量比受到纬度、经度和电导率等环境因子的影响。综上所述,环塔里木盆地红枣园土壤总体上表现出养分分配不均的现象,建议在施肥过程中适当增加氮肥的施用和有机肥的配施。

"家园"与"存在"是贯穿格非小说的两大主题。在传统与现代、乡村与城市、本土与全球、存在与现实等充满张力的矛盾关系中,格非一直在叩问和探寻着现代人"存在"的正途和理想的家园。某种意义上而言,格非对存在的追问与其乌托邦冲动相关联,因为乌托邦不仅指向"未来"社会,同时"也是对人的内在世界和存在状况的分析。"①格非对"存在"与"家园"的持续关注与探寻,对大众消费文化和娱乐文化的警惕与对抗,既源于深沉而强大的乡愁乌托邦情感冲动。

The liquid-phase coating method was used to deposit Y2O3 ceramic on the surface of α-Al2O3. The coated-Al2O3p/6061AI composites were produced using squeeze casting technology. The microstructure and tensile properties of the composites were analysed and studied. The results showed that the coated AI2O3 particles are able to disperse homogeneously in the aluminum liquid. The microstructure of the composites is more even in comparison with that of as-received powders. The tensile testing indicated that mechanical properties of the coated-AI2O3p/6061AI composites are better than those of uncoated particles. In the composite with 30% volume fraction, the tensile strength, yield strength as well as elongation is increased by 29.8%, 38.4% and 10.3%, respectively. The SEM analysis of fracture indicated that the dimples of the coated-Al2O3p/6061Al composites are more even.
