摘要
用未硫化的甲基乙烯基硅橡胶和接枝室温硫化硅橡胶（ＲＴＶ）作正电子湮没实验的结果表明，甲基乙烯基硅橡胶的τ１、τ２均较ＲＴＶ的短，而τ３；较长。对这一现象作了定性的解释。
A methylvinyl silicone rubber and a room-temperature vulcanized(RTV) graft silicone rubber were studied with the positron annihilation technique. It is shown that τ 1 and τ 2 for the RTV rubber are longer than those in the former, but τ 3 is shorter than these for the former. A qualitative explanation for the facts is given.
