The development of microwave sensors in recent two years in China are in troduced with an emphasis on spaceborne sensors without the applications in cluded. The microwave sensors as the main payloads to be boarded on the future operational satellites, such as FY-3 meteorological satellites and HY-2 marine satellite are introduced with much in detail. Besides these, four new sensors are outlined, i.e. the imaging radar altimeter,synthetic aperture radiometer, and polarimetric radiometer. Two recently conducted flight experiment campaigns are also introduced with results shown.

拓跋鲜卑是东汉檀石槐鲜卑部落联合体的西部鲜卑之一,是与匈奴融合发展起来的新部族。献帝隣确立的“十氏百世不通婚”制与周代“同姓百世婚姻不通”的实质内容相同,主旨均是繁育壮大父系宗族。这为建立人伦有等的父系宗族社会奠定了制度基础,也成为拓跋鲜卑族和华夏族建立早期国家、迈向文明道路的标识。正是基于“十氏百世不通婚”的制度规范,鲜卑十氏通过与外姓族广泛通婚,形成强大的拓跋鲜卑部落联合体乃至邦国,进而建立代、魏王国,并发展为北魏帝国,结束了五胡十六国之乱,完成了中国北方的统一。与拓跋鲜卑族和华夏族早期通过征伐等强力方式与异姓族结婚不同,华夏族在周代探索出“化干戈为玉帛”“合二姓之好”的文明道路,形成孝敬父母的华夏文明传统,生成以“和不同”为基本特征的文化基因。这种“和不同”“和平发展”的精神成长为中华文明的核心基因,是中华民族生命强韧、文化绵延广博的智慧渊源。

为评估铜陵矿区开采后废弃场地土壤重金属对人体健康和生态环境的潜在风险,以铜陵矿区典型废弃地块为例,采用单因子污染指数法和内梅罗污染指数法进行土壤环境质量评价,并结合健康风险评价模型分析地块土壤重金属污染的人体健康风险。结果显示:研究区域土壤达到重度污染水平,As、Co、V、Tl的浓度超过筛选值,研究区综合风险指数为625.94,风险等级较强;其中采样点S4附近潜在生态风险指数最大,达到“极强”等级,存在复合污染趋势。风险评价结果表明,经口摄入是该地区土壤重金属主要风险暴露途径,非致癌风险和致癌风险均为不可接受。其中As和Tl为主要风险来源,应引起重视。结论表明该地区已存在显著的潜在健康风险,本地块应重点关注Cd、As、Hg和Tl元素的污染情况,在后期开发利用过程中,需密切关注该地区重金属污染状况并进行土壤治理管控。

党的十八大以来,以习近平同志为核心的党中央坚持把解决好“三农”问题作为全党工作的重中之重,把解决好14亿人民的吃饭问题作为治国理政的头等大事。“把饭碗牢牢端在自己手中”是习近平关于粮食安全的重要战略论断。这是习近平在清楚认识国内人多地少和国际粮食贸易量有限的现实、总结历史经验、强调粮食供求紧平衡的基础上,得出的重大论断。国家粮食安全战略充分体现了习近平关于粮食安全的战略论断。习近平关于粮食安全的战略论断的深刻内涵主要有:耕地保护是战略根本,发展种业是战略源头,保障种粮收益是战略动力,党政同责是战略责任,粮食储备是战略后盾,节约粮食是战略节流。“把饭碗牢牢端在自己手中”这一战略论断对抓好粮食安全和农产品供给保障具有高屋建瓴的指导意义。

Foliar diseases are common in most maize-producing regions and have caused serious yield reduction in China. To evaluate genetic resistance of parental lines actively used in maize breeding programs to major foliar diseases, 152 maize inbred lines were tested against northern corn leaf blight(NCLB), southern corn leaf blight(SCLB), Curvularia leaf spot(CLS),gray leaf spot(GLS), common rust, and southern rust from 2003 to 2005. A small number of lines exhibited highly resistant reactions to common rust and southern rust, but none were highly resistant to NCLB, SCLB, CLS, and GLS. Although 53.3%, 40.8%, and 80.7% of lines were resistant to NCLB, SCLB, and common rust, the resistance in most lines was *** to CLS, GLS, and southern rust was rare in this collection of maize lines. Five lines,313, Chang 7-2, Qi 319, Qi 318, and Shen 137, were resistant to five diseases tested. Lines belonging to heterotic subgroup PB exhibited better resistance to the foliar diseases than lines from other heterotic subgroups, such as BSSS, PA, Lancaster, LRC, and PA. The results will be of benefit to breeders for selecting lines in disease resistance breeding programs.
