C. PALS measurements were performed for dynamically cured EPDM/PP blend as afunction of composition. The variation of free volume properties is compared with themechanical properties, and we preliminarily discuss the internal correlation betweenthem. 2. Natural polymer and its 〓 modified system PALS measurements were performed on pure chitosan and 〓-containingchitosan as a function of temperature from 290K to 380K.

c。研究了不同组分比的动态硫化乙丙橡胶／聚丙烯共混物的自由体积特性，观察到两相之间的部分相溶程度随着组分的变化而改变， D MTA、DSC的结果也证实了上述结论，与力学性能等实验结果进行比较得到了共混物的相溶性与宏观力学性能的内在联系。2。

It was found that the mechanical properties of the joints decreased by the alclad and it will be increased dramatically by removing the alclad. The effect of alclad on the bottom surface is larger than on the top surface. The mechanical properties of 2024-T3 joints will fall down because alclad is entrapped into the welded joints by the rotating and stirring tools during the friction stir welding, similar with "inclusion" in fusion welding.

研究结果表明，包铝层的存在明显降低了2024-T3铝合金搅拌摩擦焊接头的力学性能；去掉包铝层后接头的性能显著提高；下表面包铝层对接头性能的影响大于上表面包铝层；当2024-T3铝合金表面带有包铝层进行搅拌摩擦焊接时，在搅拌头的旋转和搅拌作用下，包铝层被卷入焊缝中，形成类似于熔焊的&夹杂&，从而使得接头的力学性能下降。
