They can be classificated to two kinds. One kind is build by photomultiplier; another kind is build by MCP. The mechanism of delayed luminescence is discussed with subradiation. A photon count system is built. To proof the biophoton is a kind of ultra weak photon stream originate from exothermic reaction, and primarily discuss the relationship between the delayed luminescence and proteins activity, we chose microphyllous banyan leave , ficus elastica leave, gingkgo leave, Chinese fan palm leave, and cinnamomum camphora leave as biological samples. The ultra weak photon emission from normal biosamples, and proteins inactivated biosample were measured separately with photon count system. The results showed that the delayed luminescence of biosamples have

The whole sintering process of SHS converter fettling materials can be divided into three steps. The first step is the decomposition reaction of carbonates and sodium nitrate, which is an endothermic reaction. The second step is the SHS reaction, i. e. thermite reaction, the metal of Al reacts with CO〓, O〓, NO〓, Fe〓O〓 to form Al〓O〓. The speed of thermite reaction is very quick, and accompanied with large amount of heat emission and temperature rise. The third step is the reaction of spinels formation. The Al〓O〓 produced by SHS reacts with MgO to form spinels.
