Examples
- The primary bands run at about 106 , 87 , 67 , 53 , 4538 , 33 , 26 and 14kda . in addition , there are 6 other components in water - soluble matrix ( wsm )
3 、海缥峭中镁( mg )含量低，银( sr )含量高的特点，适合于文石的形成。 - The smectite - to - illite transformation has close relation with sedimentation and thermal history of basins . so illite can indicate period of oil formation . dating of authegenic illite is an important task
伊利石的形成与盆地的沉积和热演化有密切关系，它可以指示油气的形成时代，因此测定成岩伊利石的形成年龄是一个重要的课题。 - Ettringite in cement hydration products " value k " method of xrd and some accurate results were obtained . this method shows practically significant in studying the formation mechanism and stability of ettringite
摘要本文用x射线衍射法定量分析了水泥水化产物中的钙矾石，得到了较为准确的结果，该方法对研究钙矾石的形成机理和膨胀机理提供了重要的参考依据，具有理论和实际意义。 - This paper provides a review of the reported case about the micro - structure of thaumasite and its micro - analysis methods , the characteristic properties and the composition of thaumasite and the formation mechanism of thaumasite and the main factors affecting its formation etc
摘要主要介绍了碳硫硅钙石的组成与结构，分析鉴别方法以及水泥基材料中碳硫硅钙石的形成反应机理及其影响因素。 - The studies indicate that different content of pyrophyllite and dolomite can cause the following three cases : ( 1 ) making the refractory point decrease linearly and , to some extent , influencing the microstructure and properties of sintered body ; ( 2 ) acceleratingmullite formation during sintering , reducing thermal expansion coefficient of bond , reinforcing the matching nature and improving the flexural strength and shock strength ; ( 3 ) preventing sic grinding tool from generating black core , expanding suitable sintering temperature range of sic grinding tool
同时，也不同程度地影响了磨具烧结体的微观结构和性能； ( 2 )可促进在烧结过程中莫来石的形成，降低结合剂的热膨胀系数，加强了结合剂与磨料的匹配性，提高了磨具的抗折强度和抗冲击强度； ( 3 )在一定温度范围内还可防止碳化硅磨具出现黑心现象，拓宽了碳化硅磨具的烧结温度适应范围。
