1) period migration
周期偏移
1.
The interpolation format in time domain and step-by-step integration algorithms are adopted from literature \ and wilson-θ method is used bo discuss some precision problems of algorithms for dynamic respectively from the views of interpolation function, satisfaction to dynamic equation, period migration and amplitude decay yielded by numerical calculation.
采用文献 [1]的时间域插值格式和逐步递推计算格式以及wilson -θ法的插值格式和逐步计算方法 ,分别从插值格式角度、满足动力学方程的角度以及数值计算产生的周期偏移和振幅衰减角度对动力学问题中有关逐步计算格式的精度问题进行了讨论。
2) offset for replenishment cycle
补货周期偏移量
3) sliding period
滑移周期
1.
Based on the basic principle of sliding grid method, a new concept of sliding period was proposed and used to simulate the flow fields in stirred vessels with novel combined inner and outer agitators which are rotating in opposite directions.
以滑移网格法的基本思想为出发点提出了滑移周期的概念。
5) periodic bias
周期性偏压
1.
At the same time, the DLC film deposited at periodic bias is.
结果表明:在无偏压或周期性负偏压下制备的DLC薄膜的sp3含量比连续负偏压下制备的薄膜的sp3含量要高;同时在周期性偏压下制备的薄膜表面较光滑,其表面粗糙度仅为0。
6) eccentricity cycles
偏心率周期
1.
2% error in calculating the current orbital model for the last 250Ma makes possible stratigraphic subdivisions based upon eccentricity cycles.
介绍了偏心率周期在地层和古气候研究方面的新发展。
补充资料:创建偏移剖面
要创建偏移剖面,必须通过在“草绘器”中进行草绘以定义切口轮廓。然后,垂直于草绘平面投影此轮廓。单击 或“视图”(View)>“视图管理器”(View Manager)。“视图管理器”(View Manager) 对话框打开。单击“剖截面”(Xsec)。单击“新建”(New)。出现一个缺省的剖面名称。按 ENTER 键。“剖截面创建”(XSEC CREATE) 菜单打开。单击“偏移”(Offset)>“一侧”(One Side) 或“双侧”(Both Sides)>“完成”(Done)。“选取”(SELECT) 对话框打开。选取草绘平面,并定义查看方向和草绘方向。进入“草绘器”。选取用于尺寸标注的参照图元。草绘剖面轮廓并单击 退出“草绘器”。 在“视图管理器”(View Manager) 中,单击“显示”(Display)>“设置可见性”(Set Visible)。“可见性”(Visibility) 对话框打开。单击“显示剖面线”(Show X-Hatching) 查看剖面。单击 预览或单击 接受选取的选项。
