An international cooperative study of the Late Cretaceous biota and non-marine strata including the Cretaceous-Paleogene(K--Pg) boundary in Jiayin near the Heilongjiang River,China during 2002-2010,is summarized in this paper. The strata includes the Upper Cretaceous Yong'ancun-,Taipinglinchang-,Yuliang-zi-,and Furao formations,and the Paleocence wuyun Formation consisting of Baoshantou Member and a Coalbearing Member. Seven palynological assemblages from Santonian to Paleocene are recognized,which is used for definition of the K--Pg boundary. Through the palynological analysis of three drilled boreholes (XHY-2005,2006,2008) in Xiaoheyan of western Jiayin,the K--Pg boundary is defined within 20. 00-20. 05 m in the borehole XHY-2006 (as a standard boundary) which is just between the top of Furao Formation (late Maasterichtian) and the base of Baishantou Member (early Danian) . These new research results are supported by paleo- magnetic,geochemical and other analyses,also. On the other hand,the presence of eight taxa of Maasterichtian dinosaurs (mostly hadrosaurids) have been recognized by the authors; and two mega-plant assemblages from the Yong'ancun Fm (Santonian) to Taipinglinchang Fm (Campanian) are confirmed. These research a-chievements indicate that the Upper Cretaceous-Paleocene in Jiayin can be well correlated to the strata in the neighboring Zeya-Bureja basin,Russia. The K--Pg boundary definited in Jiayin is the first well documented non-marine K--Pg boundary in China. Also the related paleoclimate,paleoenvironment and the mass extinctions in this area during the Cretaceous-Paleocene transition are also discussed.

目的研究重庆市中医院近十年治疗的3303例儿童哮喘患者,先天禀赋与后天发病存在的关联以及儿童哮喘体质分布的中医运气学趋势。方法构建3303例儿童哮喘出生、发病关联五运六气数据库,以SPSS 19.0软件单因素方差分析Duncan比较,以及描述统计,取95%置信区间方法统计不同组别儿童哮喘出生、发病分布差异。结果3303例儿童哮喘患者在先天禀赋与后天发病关联及趋势上,存在特异性的岁运、主运、客运高发人群分布。结论儿童哮喘发病人群存在特异性的中医五运六气禀赋体质与高发运气时节,中医运气学理论能够用于不同运气禀赋儿童哮喘的预防、治疗。

在大田条件下,研究了施氮量对不同类型水稻品种吸氮特性及氮肥利用率的影响。结果表明:随施氮量的增加,不同类型水稻品种的吸氮量、百千克籽粒需氮量均增加;产量随百千克籽粒需氮量的增加呈先增加后减少的趋势,产量在9000～10500kg·hm-... 详细信息

在大田条件下,研究了施氮量对不同类型水稻品种吸氮特性及氮肥利用率的影响。结果表明:随施氮量的增加,不同类型水稻品种的吸氮量、百千克籽粒需氮量均增加;产量随百千克籽粒需氮量的增加呈先增加后减少的趋势,产量在9000～10500kg·hm-2的百千克籽粒需氮量集中在1.9～2.2kg。在本试验条件下,镇稻88、武运粳7号、8优161、常优1号的氮肥利用率随施氮量的增加呈上升的趋势,而武育粳3号、8优父、扬稻6号、扬籼4号、两优培九、汕优63的氮肥利用率随施氮量的增加呈上升的趋势,至中肥处理达最大,高肥处理则显著下降;产量与氮肥利用率呈极显著的线性相关性,产量在9000～10500kg·hm-2的氮肥利用率都在40%左右。
