The dispersion of the modified nano - sized caco3 in the pvc matrix was observed in tem ( transmission electron microscope ). the influences of surface treatment and the contents of nano - sized caco3, extrusion technology and other additives on the properties of the composites were investigated. the results show that the surface treatment of the nano - sized caco3 particles with wet method enlarged the specific surface area and reduced the surface energy of the particles, and made the particles dispersed at the nanometer level in the pvc matrix, which improved the mechanical properties of the composite
本課題為了解決納米caco _ 3在pvc中的分散問題，對納米caco _ 3粒子進行了濕法處理，採用雙螺桿擠出法制備出具有良好性能的pvc -納米caco _ 3復合材料；對復合材料的力學性能和加工性能進行了測試；利用tem （ transmissionelectronmicroscope ，透射電子顯微鏡）觀察了納米caco _ 3粒子在pvc基體中的分散情況；討論了納米caco _ 3的表面處理方法、納米caco _ 3的含量、復合材料的制備工藝以及各種助劑對復合材料各項性能的影響。 -
Rayleigh wave method is a jumped - up and effective in - situ test. we can inverts the velocity structure of the strata through the quantitive interpretation of dispersion curve of rayleigh wave with this method, then distinguish and determine the physico - mechanical properties of the strata by the wave velocity in order to solve the geotechnical problems
瑞利波法是近年米新興的、行之有效的原位測試方法，該法通過定量解釋實測瑞利波頻散曲線，反演地層速度結構，利用波速區分和確定地層物理力學特性，以解決巖土工程問題。
