The effects of TiO2 additives on densification,microstructure and microwave dielectric properties of CaSiO3 materials have been investigated.The microstructure of CaSiO3 doped with TiO2 was analyzed using X-ray diffraction(XRD),scanning electron microscopy(SEM)and microwave dielectric measurement.The pure CaSiO3 ceramics sintered at 1360℃ exhibited microwave dielectric properties: a dielectric constant εr value of 6.9,a quality factor Q×f value of 26,611 GHz,and a temperature coefficient of resonant frequency τf value of-27.5ppm/℃.

臭氧(O_3)是最主要的空气污染物之一。水稻是世界上最重要的粮食作物,准确评估近地层O_3浓度升高对水稻生长发育的影响具有重要意义。尽管前人对O_3胁迫下水稻生长和产量响应的基因型差异作了少量的报道,但均是在气室(封闭式或开顶式)条件下进行。同气室相比,开放式空气中O_3浓度增高(FACE,Free Air ozone Concentration Enrichment)系统代表了目前我们对未来稻田

摘要：文化渗透于社会生活的各个方面，英文翻译不可避免地受到文化因素的影响。只有深刻地把握不同文化背景知识、不同民族思维模式的差异，以及对英汉两种语言风格的理解，才能进行成功的翻译。反过来，翻译也有助于学生对文化的对比和跨文化理解。 关键词：翻译；文化；对比；理解 中图分类号：G632.0 文献标识码：A 文章编号：1992-7711（2017）02-0017 近些年来，翻译中的文化问题越来越
