The effects of two types of emissive materials on operation properties of M type cathode were also investigated.
To remove residual organic materials, the sample was heat treated at 500 °C for 2 h and nano emissive materials were produced.
During the impregnating process, it was observed that the melting point of emissive materials produced by the sol-gel combustion was lower than that of emissive materials synthesized by the ball-milling method, which is about 100 ͦC.

Effect of dynamic change of activities of enzymatic in Sugarcane field with different coating material wei-sheng Shi 1, a, hai-ming Liu, zheng Peng, yu-shu He and fu-jie Zhang 1 Faculty of Modern Agriculture Engineering, Journal of Kunming University of Science and Technology, Kunming 650500,China a shiweisheng888@sina.com Key words: coated material ; activities of enzymatic; dynamic change; Abstract: the effect of dynamic change activities of enzymatic in Sugarcane field with different coating material was studied With three kinds of coated compound fertilizer as raw materials.
In such an environment, the coated compound fertilizer as raw materials of the Idesia polycarpa var.vestita oil can induce the soil enzymatic activities of sucrase more effectively than the coated compound fertilizer as raw materials of polyolefins.
