计算单元

The arithmetic/ logic unit is the functional unit that provides the computer with logical and computational capabilities.

计算或逻辑单元：计算器是为计算机提供逻辑和计算能力的功能单元。

In the process of elliptic curve digital signature verification, the elliptic curve scalar multiplication and the elliptic point addition, which are under different coordinates, need to be calculated twice and once, respectively. With operands allocation, the two operations in the thesis are using the shared registers and arithmetic units as well as the same modular inverse process. No extra resource is needed for the introduction of point addition. Hence the resource utilization efficiency is optimized.

论文对这两种不同坐标系下的计算进行了寄存器和运算单元的统一调度，使它们的求逆运算共用同样的流程，减小了控制状态机的复杂度，并且在实现标量乘法的基础上，没有增加额外的运算单元或寄存器，点加运算的所有计算资源均和标量乘法公用，最大限度的提高了资源利用率。

The distribution of Gauss points is also given. By using this kind of beam element, the finite element program is worked out and proved to be feasible and efficient by comparing with representative examples and experimental results.

在此基础上编制了有限元程序，通过与经典算例和试验结果的对比分析表明，这种梁单元能以较少的单元划分获得较高的精度，从而节省了计算时间，具有更高的计算效率。

The finite element analysis is applied to the frame of a 8 t truck based on ANSYS. The geometrical model and the finite element analysis model with the solid92 element are built. Based on the models, the stress and deformation of the frame are calculated. It may be applied for the improvement of the frame.

四结点蜕化壳单元和刚体壳单元分别用来建立板和模具的有限元模型；更新Lagrange法和速率型本构关系被用来处理板料变形中的大应变和大转动；材料模型采用塑性各向异性屈服与等向强化模型；通过主从面模型定义板料和模具的接触，接触算法采用运动约束法，摩擦力用库仓定律计算；并利用动力松弛法对回弹过程进行了计算。

In this method, FEM and BEM decrease the calculation time, and tetrahedral element method can avoid deformation element.

有限元和边界元相结合的方法大大减少了计算工作量和计算时间；模型中采用四面体单元剖分线性单元网格，很好地避免了传统方法中出现的准六面体畸形网格。

The workunits generated at first by the S5R4 workunit generator all at the upper end of the runtime variation for a given frequency band. They should average out over time, but at the beginning we got all "bad" ones.

S5R4目前的任务单元计算时间都偏长（译注：所以导致得分率的实际降低比例超过了25%），以后的任务单元计算时间平均来说会比较正常，但现在最早这批全是时间比较长的

In order to remedy this kind of shortage, this paper presents a quick volume rendering method, for the finite element data field of dam seismic response, choices the slicing direction relying on the element surface which normal line has the smallest included angle with the view direction, slices elements to many quadrilaterals, blends the colors of these quadrilaterals by using OpenGL blending technology, and then superimposes all elements one by one.

为了弥补传统体绘制静止画面不能明确判断场值集中部位的不足，提出一种快速体绘制算法，针对大坝地震反应有限元计算数据场，根据每个单元法线与视线夹角最小的表面来选择剖切方向，将单元剖切成多个四边形面后，对单元的绘制顺序进行合理排序，利用OpenGL图形库函数进行颜色融合，再将各个单元依次叠加，从而生成了三维数据场的体绘制图。

Compared with common quadratic elements, this kind of interpolation method achieves the same accuracy by adding a rotation degree of freedom on every vertex without using midpoints of edges or interior points. Whether consider from the running time or the space that data occupied, this sort of element is more effective than 8-nodes quadrilateral.

和一般的二次单元相比较，这种插值方法不需要使用单元边中点或者内部节点进行插值，仅在每个顶点上增加一个转角自由度就可以得到和二次元相当的精度；无论从运算时间还是数据所占用的空间来考虑，这类单元的计算花费均大大低于八节点四边形二次单元。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
