| 摘要 |
The invention provides a reaction system comprising: a first reaction promoter capable of converting a first substrate into a first substance; and a plurality of microcapsules, each of said microcapsules comprising a second reaction promoter encapsulated within an encapsulant, said second reaction promoter being capable of converting a second substrate into a second substance. The second substrate is capable of passing through the encapsulant to contact the second reaction promoter and the second substance is capable of passing out of the microcapsules through the encapsulant. In the reaction system, either (a) the first substance is, or is capable of being converted into, the second substrate and, in operation, the conversion of the second substrate by the second reaction promoter occurs to a greater extent than the conversion of the first substrate by the second reaction promoter and the conversion of the second substance by the first reaction promoter is low, or (b) the second substance is, or is capable of being converted into, the first substrate and, in operation, the conversion of the first substrate by the first reaction promoter occurs to a greater extent than the conversion of the second substrate by the first reaction promoter and the conversion of the first substance in the microcapsules is low. |
