Study on paleoclimatic records from cave calcite deposits［J］.

洞穴碳酸钙沉积的古气候记录研究［J］。

The paleoclimatic implication of susceptibility and carbonates content is not clear, and they can't be used as strict proxy.

黄土-古土壤中的磁化率值和碳酸钙含量古气候意义不明确，仅可作为参考气候代用指标。

Thirdly, in reproducing pedological process and sandstorm activity, grain- size, magnetic susceptibility , Calcium carbonate and pH value of soil four indexes have good instructions.

三在再现成壤环境及沙尘暴活动时，粒度、磁化率、碳酸钙和土壤pH值这四项指标有着较好的指示意义，而且各指标之间对应良好。

The peak of grain-size hit 50 ~ 10um and Calcium carbonate value correspond the weak pedological process, in this period the sandstorm activity aggravated.

这些气候代用指标为本文研究关中平原中西部地区全新世以来的成壤环境演变和沙尘暴研究提供了良好的条件。50～10μm粗粉沙、碳酸钙曲线峰值对应于成镶微弱，沙尘暴活动加剧的时期。

Furthermore,the dispersivity of PESA could be further enhanced by combination with other inorganic or organic...

对PESA与其他几种分散剂进行复配，其中加入与碳酸钙的质量比为1.8%的PESA、0.7%的六偏磷酸钠和0.1%的十二烷基硫酸钠3元复配的分散性能和稳定性最佳。

The scale inhibition mechanism of PESA was proposed on the basis of characterization of transformation of calcium carbonate crystal by means of X-ray Diffraction and scanning electron microscopy. The effect of temperature on corrosion inhibition efficiency of PESA was investigated and the Bockris substitution model is proposed to study the thermodynamics of inhibiting process of PESA. The calculation results show the adsorption of PESA on carbon steel is a spontaneous exothermic process with the increase of entropy.

通过X射线衍射和扫描电镜分析手段研究了聚环氧琥珀酸加入前后碳酸钙垢晶型的变化，在此基础上探讨了聚环氧琥珀酸的阻垢机理；考察了温度对聚环氧琥珀酸缓蚀性能的影响，根据Bockris置换模型，计算出中性水质中聚环氧琥珀酸在碳钢表面吸附的热力学函数，计算结果表明：聚环氧琥珀酸在碳钢表面的吸附是一个放热、熵增、自动发生的过程。
