牡丹江市对俄经贸合作的变动趋势及对策建议

中俄边境贸易开始升温，双边经贸合作逐步走向成熟，牡丹江市对俄经贸合作既面临新的发展机遇，也存在一些不利因素。牡丹江市应审时度势，利用优势，争取批准牡丹江市为边境开放城市，开通绥芬河、东宁边民互市贸易区，授予部分边境贸易管理权，加速转变贸易方式，调整进出口贸易结构，扩大经济技术合作的领域，扩大劳务输出，建立边贸法律仲裁机构，开通对俄直接通话。

Combined deformation of filament-wound cylinder and application to torsion vibration control

The combined deformation and mechanical properties of filament-wound cylinder of filament reinforced composite materials are investigated. A method of using filament-winding composites to reduce the amplitude of torsion vibration in the case of special stimulated vibration is established. A design formula of anisotropic filament-wound cylinder to reduce the torsion vibration of axle components is obtained. The results indicate that by putting the filament-wound cylinder on an axis, the torsion vibration of the axis can be reduced effectively.
