The results showed as follows:Maize grown in the treatment of compound fertilizer containing urea alone had significantly lower germination rate than the maize receiving mixed CO(NH2)-N/NH4+-N or mixed NO3——N/NH4+-N in compound fertilizers in Udic Isohumisols.However,there was no significant affect of nitrogen forms on maize germination rate in Udic Cambosols.

结果表明，在黑土上，施用酰胺态氮为单一氮素形态的复混肥料时，玉米的出苗率明显下降；而用部分铵态氮替代酰胺态氮后制成的混合态氮和由铵态氮与硝态氮构成的复混肥对玉米的出苗率影响较小；不同氮素形态配比的复混肥对潮土上生长的玉米出苗影响较小，各处理的出苗率可达到90%以上。

The electronic structures and the non-linear optical properties of bis schiff base and their derivatives have been studied using FF/HF method.The effects of electron donor/acceptor on nonlinear optical property were examined at the molecular level.As a result,the NLO coefficients of the substituted compounds are all larger than the unsubstituted compound.Among them, the β value of compound 4 is the largest one.

Zirconia/graphite compound mold core was prepared by the coating, in which the silicon sol was used as binder and zirconia was used as refractory materials. The application feasibility of metal particles as a coolant in the solidification process was studied, and the application of metal particles as subsidiary coolant in the liquid metal cooling of directional solidification were analyzed and studied in this investigation. The conclusions can be drawn as follows: 1 The zireonia/graphite compound cores fabricated by brushing coating which was prepared by making silicon sol agglutinated zirconia as a refractory material were casteded at 800℃and 1000℃respectively, and the results show that the strength of the mold core is strong enough to meet the requirement of practical casting.
