| 2. | It is shown that distribution of dynamic response of dam is mainly alike . the maximum acceleration , the maximum displacement and the maximum shear stress are different obviously 可以看出,两种方法算得的坝体动力反应分布规律基本一致,但坝体的峰值加速度、峰值位移及峰值动剪应力等均有明显的差别。 |
| 3. | Kickdown ( depressing the accelerator beyond full throttle ) = downshifting to a lower gear = maximum acceleration . once the desired speed is attained , ease up on the accelerator - the transmission shifts up again 似乎是说油门踩到底时,压下这个开关,降档加速,当希望的速度达到时,再自动升档,是否这么理解? |

| 5. | The numerical results show that the horizontal variation of response acceleration of gravity retaining wall is quite small since its lateral rigidity is large enough , the response at a given height level can be considered as the same , the maximum accelerations at different heights on the central vertical line can describe the distribution of earthquake load along the wall height in static analysis very well 数值结果显示,重力式挡土结构刚度很大,地震加速度反应在水平方向差异很小,可看作是同步的,可取中心线上各点最大加速度来描述静力法中地震作用沿高度的变化规律。在沿墙高度方向,加速度分布不是呈直线变化,比较复杂,总的变化趋势大体一致。 |
| 6. | 2 . studying the effects of soft layer and hard layer on seismic response . we further investigate the behavior of both the soft layers and the hard layers with the shear wave speed less than 500m / s effecting on the maximum acceleration and the shape of response spectrum , respectively 本文基于已有研究结果进一步分析了软夹层对场地地震动谱形状和峰值加速度的影响,以及剪切波速小于500m s的硬夹层对场地地震动谱形状和峰值加速度的影响,统计分析了软、硬夹层对场地地震反应影响的特点规律和程度。 |
| 7. | This paper uses the program to calculate the dynamics performance of small slack coupler that designed by qiqiha ' er vehicle ( grounp ) company . by compared maximum coupler force and maximum acceleration of car body with common slack coupler at condition of train starting , braking , emergency braking and releasing , we verified that small slack coupler is better than common slack coupler in dynamics performance . this paper also calculated the train dynamics performance parameter with different buffer and braking system , running in different line and using different operating method 本文利用列车纵向动力学模拟程序,计算了齐齐哈尔车辆(集团)公司研制的13号小间隙防脱车钩的纵向动力学性能,通过比较各个车钩间隙下列车最大纵向车钩力和列车最大加速度的数值,得出小间隙车钩在列车启动工况、常用制动工况、紧急制动工况、缓解工况的纵向动力学性能都较原有车钩性能优异的结论。 |
| 8. | Under the control of a current loop , the system can make advantage of the motor ' s ability of over - current with a maximum limit , as a result , the motor can implement constant - current staring under a maximum let - through current . therefore , the motor ' s rotational speed can rise at a maximum acceleration and reach the given speed within the shortest time 在电流环的控制下,系统在起动的时候能够最大限度的发挥电机的过流能力,使电机以最大允许的起动电流恒流起动,则电机转速可以以最大的加速度上升,并且以最快的时间达到给定转速。 |
