Cobalt and sulfur content of cathode material of the thermal battery was determined separate using potentiometrie titration and sulful transform methods,acquire the determination way of cobalt bisulfide content of sample atomic distribut of cobalt and sulfur in sample by calculate experimental data of Cobalt and sulfu atomic distribute.

The experiment and study on material proportioning and sintering process paramter of basic sirttered ores are done by use of ertnogonal oxperimental procedure under the condition of raw material of Laiwu Iron and Steel General works, and optimum raw material proportioning and sintering process parameter of sintered ore are established.

As the annual slowly\|increased price influences the depreciation of fixed assets, the method of accounting it by the historical cost principle is put forward because such a method can better embody the matching principle as well as the principle of stability.

Through expounding the conception of the intangible assets and analyzing on the cost-like treatment and the capitalized treatment,and as for the affirmation and the discovery of the intangible assets,this paper puts forward a treating method that is based on the capitalization and gives consideration to both the conservatism and matching principle.

In this study,the best ratio of raw materials and the technical parameters of the produce were decided.

The parasitic rate and control effect kept increasing with the spore ratio of Trichoderma to A.
