The distribution of gear's contact stress, root stress, and contact engagement line in the engagement situation of gear pairs, were obtained on the base of explicit integration method. 3. Adopting the method of system matrix, the torsional vibration differential equation of general shafting was gained. The simple harmonic forms of excitation torque under the normal combustion or piston flameout of in-line engine and v-type engine were analysed. The decoupled algorithm of free vibration and forced vibration and the solution to the vibration damper's energy of resistance and the off-resonance calculation were studied. The sensitivity formulations of the natural frequency and vibration mode to physical parameters of system were derived by solving the eigenvalue problem. These sensitivity formulations provided the theoretical base for the dynamic modification of structure.

Our project is based on Cenozoic volcanic rocks and deep seated xenoliths in it to reconstruct the source composition and ctructure. We did field investigation, collection of samples, determination of age and composition characteristics of selected samples. The new achievements are following. 1 recognized a potassic metasomatic source of the Cenozoic volcanic rocks through an integrated research of volcanic rocks and their sources. 2 analysis of TM images suggests the Tuoyun basin is a basin with a volcano group instead of a simple volcano-tectonic basin. We found several volcanic craters and cone, and detected three such craters. 3 systematic reseach of volcanic sections and collection of samples both of volcanic rocks and xenoliths, the later includes peridotite, granulite, gneiss and variety of megacrysts. This is propitious to our further research at this rigion. We would like to point that we collected some peridotite large than 20cm in diameter. It could used to variety of analysis and end the history without mantle chemistry records in the region. 4 we got a U-Pb SHRIMP age of 3.87 Ma for the Kangxiwa basalt.It is the youngest record of U-Pb SHRIMP age in China and provide a chronology restriction for last uplifting of Tibet plateau. 5 the investigation of alkali syenite-synogranite in Taxkogan suggests that the origin of Parmir syntex is related to the Cenozoic magmatism.
