查询词典 parametric curve

If you bent or folded rock, the inside of the curve was in a state of compression, the outside of the curve was under great tension, and somewhere in the middle was the surface of no strain.

&假如你把一块岩石弯曲，曲面的内侧会是一种紧缩的状态，外侧则处于巨大的张力，而在中间的某处则是光滑无痕的平面。&

Concerning with the selection of the ways of calculation the thesis indicates all of them including layerwise summation method, double curve method and logarithm curve method can meet the demands of the projects.

在研究课题对于计算方法的选择，认为分层总和法、双曲线法和对数曲线法均能满足工程需要。

This paper not only fits the desired elastic potential energy curve to the summation curve of generated elastic potential energies by the balancer, but also provides a concrete design approach in synthesizing the four-bar linkage elastic balancers to modify the dynamics of the original system and therefore reduce actuator torque and force.

系统之弹性位能曲线常为不规则，本文提出以附加弹性平衡器之方式，不仅符合期望之弹性位能曲线，同时亦提供一套具体之四连杆及弹簧平衡器设计方案，以修正原系统之动态行为，并降低制动器输出之力矩和力量。

Experiments were carried out to verify the static model. Experimental results show that the experimental curve matched well with the simulated curve, and there was certain error between them (maximal static error is 0.035 rad). The error cause was analyzed. Then the experiments were carried out to measure the dynamic performances of the side-sway joint. Experimental results show that the step response time of the joint was about 2 s steady value's tolerance zone ?

完成了侧摆关节静态特性试验，试验结果与仿真曲线基本吻合，验证了静态模型的正确性，但存在一定误差（最大静态误差为0.035 rad），分析了误差原因；对侧摆关节进行了动态特性试验，试验结果表明对于不同的期望值角度阶跃信号，侧摆关节开环阶跃响应时间大约是2 s

Based on the analysis of current oscillation region of stable electric fielddomains in I-V curve,it is shown that when the applied bias voltage is changedwithin positive slope regions of I-V curve,the domain boundary between the high-and low-electric field domains does not moved,and the size of electic fielddomains regions is also not altered,while the electric filed strengths are adjusted tokeep the current conservation.

通过对稳态电场畴情况下I-V曲线中电流振荡区域的分析，证明当外加偏压在正微分电导区变动时，超晶格的高低电场畴之间的畴边界不发生移动，畴的大小不变，只是相应的电场强度做些调整以使电流守恒成立。

For example, a 19th-century mathematical curiosity called the "space-filling curve"- a sort of early fractal curve - recently resurfaced as a model for the shape of the human genome.

例如，19世纪一个数学家的好奇心-叫做&空间-充满曲线&-一种早期的分形曲线-最近重新浮出水面，作为模拟人类基因组形状的模型。

虽然会破坏我曾经希望得到的披萨定理，但我这些日子确实不再吃很多美国披萨了。上一篇：办公室八卦是好是坏？

This controller adopts different control actions according to the phase space composed by error and error change to meet the requirements. The corresponding relations between phase space and response curve of the seven different actions of this controller are analysed and curve is studies through actions.

七态控制器是根据在偏差和偏差的变化所构成的相空间上通过不同控制作用以达到满足要求的控制器，分析此控制器的7种不同作用力在相空间和响应曲线的一一对应关系，通过作用力来研究曲线。

At present,people often predict soft-ground settlement with the method of exponential curve and double-curve extent;but the result is not ideal.

With the boundary point and the known adjacent relations, an overall marching procedure can go on and the iteration process stops until the intersection curve is self-closed or reaches the border of the composite surface. In the later case, the marching must be repeated from the starting point in the reverse direction until the intersection curve reaches the other border of the composite surface.

由一个交点出发，通过计算跟踪方向和跟踪步长，迭代计算出下一个精确的交点；利用边界点和近曲面点计算方法，根据曲面片的拓扑关系找到交线所经过的下一张曲面片，从而使跟踪过程继续下去，直至形成封闭交线环而停止该交线段的跟踪，或到达复合曲面的边界后由首交点反向跟踪到达复合曲面的另一边界。
