When vulcanizates are cured by hydrosilylation, which is catalysed by chloroplatinic acid catalyst, vulcanizates can be cured adequately when C_1 gum, C_2 gum and C_3 gum are used. And their suitable amount used is 10-14 phr.

当C_1胶、C_2胶和C_3胶应用于二甲基二苯基硅橡胶时，由于硅橡胶体系中同时存在大量的苯基和稠环基团，二者会产生协同效应，所得样品具有较好的耐辐照性能。

Two inducible and extracellular chitosanases secreted by Penicillium sp. D-l were purified by ammonium sulfate precipitation as well as gel filtration. The purified enzymes of ChoA and ChoB had molecular masses of 93 and 21 kDa by SDS-PAGE. Both ChoA and ChoB have an acidic pH optimum, which were 4.0. The enzymes were stable over the pH range 3 to 5 for 1 h.
