A proposed testing method of lubricating oil and lubrication characteristics and lubrication quality for gasoline engine, when the engine oil is used for longtime of period. The result shows that the characteristics of engine oil were changed at 30,000km driving distance to the viscosity of 7.82, viscosity index 3, lubrication 40um and at 75,000km driving distance the viscosity of 76.01, viscosity index 10, lubrication of 88. The lubrication characteristics and quality of lubrication and performance of lubricating oil was changed rapidly for the driving of distance. The result dose not consider the properties of fuel used.

Since virus resistant plant was developed by using coat protein of TMV, plant virologists have attempted to produce numerous virus resistant plants by using the viral movement protein, antisense RNA, catalytic RNAs, anti-viral protein antibodies. These strategies have been limited to the developement of broad-spectrum virus resistant plants. The purpose of this study was to produce broad-spectrum virus resistant plants using the ssDNA specific single-chain antibody fragments (scFv). Single-chain antibody fragments are recombinant proteins composed of variable domains of an immunoglobulin fused by a flexible linker DNA. ssDNA specific scFv gene was amplified by polymerase chain reaction (PCR) with mixed primer designed by conserved sequence in each variable fragment. Recombinant scFv gene was cloned into plant transformation vector pBI121 to express in plants. The cloned scFv gene (pBI-scFv) was transformed into tobacco by agrobacterium mediated transformation. We have obtained four putative transgenic plant lines.
