简介:送检地下水水型为HCO3^--SO4^2--Ca^2+-(Mg^2+)型,酸碱度为中性、水介质属氧化型(Eh=640my)、低矿化,样品水中各项水质分析项目为,K^++Na^+,Ca^2+,Mg^2+,Fe^3+,Cl^-,SO4^2-,HCO3^-,CO3^2-,NO3^-,OH^-;所对应分析值为0.670×10^-3,1.200×10^-3,0.400×10^-3,1.79×10^-3,0.036×10^-3,0.88×10^-3,2.074×10^-3,10^-5.863,0.035×10^-3,10^-7.07。
简介:合成了六铝酸盐SrNiAl11O19并用XRD、UVDRS、TGDTA和TEM等技术对其进行了表征。在750℃于SrNiAl11O19上进行的甲烷与二氧化碳重整反应表明,这类催化剂较Ni/SrAl12O19具有较大活性和低积碳能力,在催化反应过程中可有效地抑制Ni颗粒的增大。
简介:采用与示波器同步的扫描场探测光磁共振,使光磁共振信号稳定;选择扫场的同一点(最好选在峰点或谷点)作参考点。有利于结合实际情况测地磁场水平分量BE11。
