The indentation loading curve with a spherical diamond tip was employed to determine the yield strengths and hardening indices of Cu films which were prepared on silicon substrates by different ways with the same thickness of 1. 5μm. The result showed that the yield strength of the Cu film depends on the deposition technology, and is much higher than that of the bulk material.

结果表明，在薄膜厚度相同的条件下，铜膜的屈服强度与铜膜的制备方法有关，选择IBED法较MS法可获得更高的屈服强度〓此外，由两种方法所镀制铜膜的屈服强度均远高于其体材，这与铝膜的情况相一致，说明薄膜与整体材料在强度方面存在显著差异的结论具有普遍性。

The grafting effect and mechanism was charac- terized by FTIR,The heat stability of unvulcanized and dynamical mechanical proper- ty of vulc- lcanizates of SBR and SBR-g- were tested by TG and DMA respectively. medium-resistance properties of SBR and SBR-g- vulcan- izates were also investigated.The results showed that addition of St accelerated GMA grafting onto SBR and control the decomposition of SBR. When the conditions were GMA/St/DCP was 8/4/0.3 and grafting temperature was 160℃.
