浅层地温对作物种子发芽和生长具有重要作用。本文利用五道沟实验站近50年浅层地温(0~40 cm)实测资料,采用Mann-Kendall检验、斯皮尔曼相关性分析、气候要素变化趋势分析和其他气候要素筛选,分析研究区近50年浅层地温年、季尺度演变规律,提出浅层地温与气温、降水量、风速、日照时数和水汽压力差多气象要素的相关性,并构建了多元回归预测模型。结果表明,(1)年际变化上,研究区域各层地温均呈现上升趋势,各层地温的变化趋势基本一致。各季浅层地温变化趋势不尽相同,冬季地温趋势率最大,春季、夏季和秋季浅层地温升温趋势在较小范围内波动。(2)在Mann-Kendall突变检验中,0、10、15、20和40 cm浅层地温分别在2012、2018、2015、2017和2017年发生突变,在这些年份发生突变后地温有明显上升趋势。(3)冬季浅层地温与气温呈极强正相关关系(R2>0.8),不同季节下研究区风速、日照时数和水汽压力差与浅层地温存在一定的线性相关性。(4)建立了不同季节浅层地温与各气候因子预测模型,并且用该模型对2022年月平均地温进行拟合检验,该模型精度较高,可用于研究区地温预测。

西岭金矿床位于三山岛金矿床东侧,是当前胶东金矿集区内新发现的单一矿体规模最大、埋藏最深的金矿床。在地质观察的基础上,开展了不同深度的黄铁矿热电性特征研究。结果表明:西岭金矿床黄铁矿热电系数离散范围和离散度整体较大且相对稳定;浅部黄铁矿热电导型均为N型,而深部均为P型;成矿温度主要集中在250~360℃之间,属中—高温热液型金矿床;计算得出黄铁矿热电导型变化梯度值较小,并估算出矿体剥蚀率约为75%。综合黄铁矿各类热电性特征参数,认为西岭金矿床深部仍有较大的找矿前景,矿体最大埋深可达-3000 m标高。已知金矿体具有向NE侧伏的规律,认为沿着NE侧伏方向至-3000 m标高处是有效的深部找矿靶区位置。西岭金矿床黄铁矿热电性特征研究可为胶东地区金矿床的深部找矿预测提供科学依据。

MicroRNAs （miRNAs） are endogenous 22-nt RNAs, which play important regulatory roles by post-transcriptional gene silencing. A computational strategy has been developed for the identification of conserved miRNAs based on features of known metazoan miRNAs in red flour beetle （Tribolium castaneum）, which is regarded as one of the major laboratory models of arthropods. Among 118 putative miRNAs, 47% and 53% of the predicted miRNAs from the red flour beetle are harbored by known protein-coding genes （intronic） and genes located outside （intergenic miRNA）, respectively. There are 31 intronic miRNAs in the same transcriptional orientation as the host genes, which may share RNA polymerase II and spliceosomal machinery with their host genes for their biogenesis. A hypothetical feed-back model has been proposed based on the analysis of the relationship between intronic miRNAs and their host genes in the development of red flour beetle.

Chinese Journal of Chemical Engineering 2013年第2期21卷 199-204页

Four kinds of Ca-based sorbents were prepared by calcination and hydration reactions using different precursors: calcium hydroxide, calcium carbonate, calcium acetate monohydrate and calcium oxide. The CO2 absorption capacity of those sorbents was investigated in a fixed-bed reactor in the temperature range of 350-650℃. It was found that all of those sorbents showed higher capacity for CO2 absorption when the operating temperature higher than 450℃. The CaAc2-CaO sorbent showed the highest CO2 absorption capacity of 299mg·g-1. The morphology of those sorbents was examined by scanning electron microscope (SEM), and the changes of composition before and after carbonation were also determined by X-ray diffraction (XRD). Results indicated that those sorbents have the similar chemical compositions and crystalline phases before carbonation reaction [mainly Ca(OH)2], and CaCO3 is the main component after carbonation reaction. The SEM morphology shows clearly that the sorbent pores were filled with reaction products after carbonation reaction, and became much denser than before. The N2 adsorption-desorption isotherms indicated that the CaAc2-CaO and CaCO3-CaO sorbents have higher specific surface area, larger pore volume and appropriate pore size distribution than that of CaO-CaO and Ca(OH)2-CaO.

Solar driven carbon dioxide(CO_(2))recycling into hydrocarbon fuels using semiconductor photocatalysts offers an ideal energy conversion pathway to solve both the energy crisis and environmental degradation ***,the ubiquitous presence of carbonaceous contaminants in photocatalytic CO_(2) reduction system and the inferior yields of hydrocarbon fuels raise serious concerns about the reliability of the reported experimental *** in this perspective,we focus on the accurate assessment of the CO_(2) reduction products,systemically discuss the possible sources of errors in the product quantification,elaborate the common mistakes spread in the analysis of reaction products obtained in 13CO_(2) labelling experiments,and further propose reliable protocols for reporting the results of these isotopic tracing ***,the challenges and cautions in the precise measurement of O_(2) evolution rate are also depicted,and the amplification of the concentration of O_(2) in photoreactors well above the limit of detection is still demonstrated to be the most effective solution to this troublesome *** hope the viewpoints raised in this paper will help to assessment the reliability of the reported data in future,and also benefit the beginners that intend to dive in the photocatalytic CO_(2) reduction area.
