The soil organic carbon (SOC) pool is the largest component of terrestrial carbon pools. With the construction of a geographically referenced database taken from the second national general soil survey materials and based on 1546 typical cropland soil profiles, the paddy field and dryland SOC storage among six regions of china were systematically quantified to characterize the spatial pattern of cropland SOC storage in china and to examine the relationship between mean annual temperature, precipitation, soil texture features and SOC content. In all regions, paddy soils had higher SOC storage than dryland soils, and cropland SOC content was the highest in Southwest china. Climate controlled the spatial distribution of SOC in both paddy and dryland soils, with SOC storage increasing with increasing precipitation and decreasing with increasing temperature.

研究了稀土元素Pr对快淬(Nd1-xPrx)10.5(FeCoZr)83.5B6(x=0,0.2,0.4,0.6,0.8,1.0)合金显微组织结构和粘结磁体磁性能的影响。通过部分过快淬获得由非晶和微晶共同组成的条屑,在实验优化的退火条件下晶化处理后,制备出最佳磁性能的系列粘结磁体。随Pr含量的增加,磁体的内禀矫顽力Hci单调上升,剩磁Br单调下降,(BH)m在x=0.6～0.8处达到最大值70.6kJ·m-3。Pr元素使合金非晶态的晶化转变温度和转化能降低,合金的显微组织结构变得较粗大和较不均匀,从而使快淬粘结磁体剩磁降低,但Pr2Fe14B化合物较高的磁晶各向异性场使磁体的内禀矫顽力提高。

将武钢中温沥青和太钢高温沥青在不同压力下炭化 ,进一步对所得沥青焦进行了高温热处理 ;利用扫描电子显微镜 (SEM)和光学显微镜观察所得沥青焦形貌。结果表明 :低压炭化时 ,沥青焦体积密度小 ,疏松、多大孔 ,主要为流线区域型各向异性结构 ;高压炭化时 ,沥青焦体积密度明显变大 ,孔变小且均匀分布 ,主要为小区域型和细镶嵌型各向异性显微结构。考察了不同炭化压力对浸渍增密航空刹车用C/C复合材料的增密效率的影响 ,结果显示 ,对整个沥青而言的宏观残炭率明显高于只针对样品而言的实际残炭率 ,因此有必要进行高压浸渍 /炭化实现快速增密。利用XRD和显微硬度测试仪检测了不同炭化压力所得沥青焦热处理后的石墨化度和显微硬度 ,发现高压下形成的沥青炭更难于石墨化 ,但石墨化度与显微硬度和热处理后的粗糙层 (RL)
