| 3. | Methods : the graded model of rats was set up by using the dev ice of the improved fluid - percussion model , then we observed the changes of bra in tissue of rats 方法:采用自行改进的液压冲击模型装置产生大鼠液压冲击脑外伤模型,对大鼠脑组织进行肉眼和光镜观察。 |
| 4. | Therefrom , this thesis puts forward the shock model with seven individually independent sources and structure three - dimensional exponential distribution , which its edge distribution is only bivariate distribution of marshall - olkin 由此,本文提出七个相互独立冲击源的冲击模型,构造了三维指数分布,并且它的二维边缘分布恰是marshall - olkin二维指数分布。 |
| 5. | In this paper , the effect of velocity pulse in near field ground motions is emphasized and the influence of velocity pulse to acceleration velocity and displacement in earthquake ground motions is analyzed by using simple impact modal 摘要着重介绍了几次地震中出现的近场地震动的速度脉冲特性,并利用简化冲击模型来分析速度脉冲效应对地震动加速度、速度、位移的影响。 |
| 6. | Exponential distribution is the most important distribution in relia - bility theory . in reliability history . famous marshall - olkin applied the fatal shock model with three mutually independent shock sources to build bivariate exponential distribution 在可靠性数学理论中,指数分布是一类很重要的分布。可靠性历史上著名的marshall - olkin ,利用三个相互独立冲击源的致命冲击模型,建立了二维指数分布。 |
| 7. | Meanwhile the 0 dimension 1 dimension plane wall 2 dimension models are established . using the mathematic and ansys software the numerical and soluble analyses can be got for the thermal shock model of the piston . compare the simulation results to the test results the temperature field and stress field can be got which are quite close the thermal shock situation 同时建立活塞热冲击的集总参数、 1维平壁和2维模型,应用mathematic软件和ansys软件,对所建立的活塞热冲击模型进行了解析和数值分析,利用模拟计算与试验结果相结合的方法,获得接近于内燃机活塞热冲击的温度场与热应力场分布,从而更加全面深入地了解在热冲击条件下活塞的温度场和应力场变化规律。 |
