| 1 | A Study of Mesoproterozoic Iron Cosmic Micro-spherules from 1.8 Ga and 1.6 Ga Old Strata in the Ming Tombs District,Beijing显示文摘众多的铁宇宙微小球体被发现了 fromMesoproterozoic 阶层包括 Changzhougou 形成(1.8 Ga ) 和明墓区域的 Dahongyu 形成(1.6Ga ) ,北京。每从 Dahongyu 形成的硅化的碳酸盐岩石每一件岩石样品的 3.69 kg 从 Changzhougou 形成 and56 谷物的一张粗糙的沙岩床的底部拿的一件沙岩样品的 2 kg 有宇宙的小球体的 1 ~ 30 谷物。借助于第二等的电子形象分析的宇宙的小球体的表面质地是相同的,那些从国内的参考书任何一个或国外报导了。到目前为止 1.8Ga 的 geo 年龄和从 Changzhougou 和 Dahongyu 形成的宇宙的小球体的 1.6 Ga 可能比那些在世界上报导旧。表格 1 给电子探查分析宇宙的小球体 for30 小球体谷物的数据, 44 测试如下削尖(%) :FeO, 80-95;Cr_2O_3;0-9.56;NiO, 0-0.78;咕咕叫, 0-0.46;显示 Cr_2O_3 内容更高, FeO 内容比在 Dahongyu 形成在 ChangzhougouFormation 降低。象他们岩石在 Changzhougou 和出现在 Table2 的 Dahongyu 形成之间极大地改变的主人一样的宇宙的小球体的氦 isotopic 数据。在 ~3He/~ 4He 的 Changzhougou 形成对 Dahongyu 形成 are57.5/1.23 的宇宙的小球体的数据(10 ^(-8)) ;并且在 ~ 4He 的 55.54/809.60 (10 ^(-6)cm^3STP/g) ;那些 Changzhougou 形成的粗糙的沙岩对在 ~3He/~ 4He 的 Dahongyu 形成 are3.39/2.59 的硅化的碳酸盐(10 ^( 在 ^ 3He 的 -8)) 和 4.56/2.34 (10 ^(-6)cm^3STP/g) 。氦同位素的分析数据的比率为宇宙的小球体和他们的主机岩石是不同的;例如, the^3He/~4He (10 ^(-8)) 价值是 16.96 和 0.48,并且 ~ 4He (10 ^(-6) cm^3STP/g ) 是 12.18 并且 345.98for Changzhougou 和 Dahongyu 形成分别地。世界的最旧的微晶学被发现了在,这被报导中央原生地 Satakunta 形成,芬兰。然而,宇宙的小球体从中央原生地 Changzhougou 和 Dahongyu 形成比从 Satakunta 形成的那些是 200 ~ 400 Maolder。而且,一碳的球粒状陨石谷物作为从 DahongyuFormation 在太阳的星云形成的最早的遗体第一次被发现。 | SONG Tianrui HE Zhengjun WAN Yusheng and LIU Yanxue Institute of Geology,Chinese Academy of Geological Sciences,Beijing 100037 | 2007 | Acta Geologica Sinica(English Edition)2007，81，4： | 3 |
| 2 | QNE1 is a key flowering regulator determining the length of the vegetative period in soybean cultivars显示文摘The soybean E1 gene is a major regulator that plays an important role in flowering time and maturity.However,it remains unclear how cultivars carrying the dominant E1 allele adapt to the higher latitudinal areas of northern China.We mapped the novel quantitative trait locus QNE1(QTL near E1) for flowering time to the region proximal to E1 on chromosome 6 in two mapping populations.Positional cloning revealed Glyma.06G204300,encoding a TCP-type transcription factor,as a strong candidate gene for QNE1.Association analysis further confirmed that functional single nucleotide polymorphisms(SNPs) at nucleotides 686 and 1,063 in the coding region of Glyma.06G204300 were significantly associated with flowering time.The protein encoded by the candidate gene is localized primarily to the nucleus.Furthermore,soybean and Brassica napus plants overexpressing Glyma.06G204300 exhibited early flowering.We conclude that despite their similar effects on flowering time,QNE1 and E4 may control flowering time through different regulatory mechanisms,based on expression studies and weighted gene co-expression network analysis of flowering time-related genes.Deciphering the molecular basis of QNE1 control of flowering time enriches our knowledge of flowering gene networks in soybean and will facilitate breeding soybean cultivars with broader latitudinal adaptation. | Zhengjun Xia Hong Zhai Yanfeng Zhang Yaying Wang Lu Wang Kun Xu Hongyan Wu Jinglong Zhu Shuang Jiao Zhao Wan Xiaobin Zhu Yi Gao Yingxiang Liu Rong Fan Shihao Wu Xin Chen Jinyu Liu Jiayin Yang Qijian Song Zhixi Tian | 2022 | Science China(Life Sciences)2022，65，12： | 1 |
| 3 | Agricultural Investment Project Decisions Based on an Interactive Preference Disaggregation Model Considering Inconsistency显示文摘Agricultural investment project selection is a complex multi-criteria decision-making problem,as agricultural projects are easily influenced by various risk factors,and the evaluation information provided by decisionmakers usually involves uncertainty and inconsistency.Existing literature primarily employed direct preference elicitation methods to address such issues,necessitating a great cognitive effort on the part of decision-makers during evaluation,specifically,determining the weights of criteria.In this study,we propose an indirect preference elicitation method,known as a preference disaggregation method,to learn decision-maker preference models fromdecision examples.To enhance evaluation ease,decision-makers merely need to compare pairs of alternatives with which they are familiar,also known as reference alternatives.Probabilistic linguistic preference relations are employed to account for the presence of incomplete and uncertain information in such pairwise comparisons.To address the inconsistency among a group of decision-makers,we develop a pair of 0-1mixed integer programming models that consider both the semantics of linguistic terms and the belief degrees of decision-makers.Finally,we conduct a case study and comparative analysis.Results reveal the effectiveness of the proposed model in solving agricultural investment project selection problems with uncertain and inconsistent decision information. | Xingli Wu Huchang Liao Shuxian Sun Zhengjun Wan | 2024 | Computer Modeling in Engineering & Sciences2024，139，6： | 0 |
