查询词典 perform

For example, a small low-cost wide-field refractor like the 80mm f/5 "short tube" achromats cannot easily compete with the performance of an expensive 3 element Apochromat, nor should it be expected to. These inexpensive scopes don't generally perform as well at higher powers, but they were never designed to do so.

比如像80F5这种小的低成本宽视场折射镜和与价格昂贵的三片APO根本没法比，虽然这些廉价的镜子高倍表现不好，但是它的设计本来也不是为了上高倍。

The result shows that the mixed boundary condition can greatly reduce the calculation area without affecting accuracy of the solution.It is followed by the higher accuracy of Dirichlet boundary condition which makes the boundary error greater when measured points is near the boundary, so we must take a sufficiently large border region.The homogeneous boundary condition has relatively large error, but the use of non-triangle poles devices makes apparent resistivity calculation error become small, because of elimination of the effect on potential difference for the infinite boundary. In inversion, in order to save computing time, homogeneous boundary conditions are often used to perform finite element forward calculation.

结果表明，混合边界条件精度最高，可大大缩小求解区域而不影响计算精度，其次是Dirichlet边界条件精度较高，但测点越靠边界误差会越大，必须取足够大的边界区域，齐次边界条件的误差比较大，但如果采用非二极装置，通过电位差计算得到的视电阻率，由于无穷远边界对电位差的影响基本消除，视电阻率计算误差与混合边界条件下的接近，在反演中，为了节省计算时间，经常使用齐次边界条件进行有限元正演。

A new method to perform the apportionment of system reliability with Genetic Algorithm and Fuzzy Logic is presented.

摘 要：提出一种使用遗传算法和模糊逻辑相结合进行系统可靠性优化分配的新方法。

It may be helpful to perform preliminary tests during which the temperature is varied to establish an approximate value fot the FT.

进行先期试验是有益的，其中温度可以变化，借此确定一个 FT 的大致的数值。

A good certified arborist with integrity will only perform ISA accepted practices .

一个良好的认证 arborist 与完整性，只会履行的ISA接受的做法。

In the picture all procedures need the handicraftsman purify it, and its color only involves black, white, ashy accent, therefore the folk and the style of archaize perform well.

画中所有程序都是有手工艺人精制而成，且色彩只有黑，白，灰调，所以画的民间性和仿古性表现处理的很好。

Scrub jays know that other jays are thieves and that stashed food can spoil; sheep can recognize faces; chimpanzees use a variety of tools to probe termite mounds and even use weapons to hunt small mammals; dolphins can imitate human postures; the archerfish which stuns insects with a sudden blast of water, can learn how to aim its squirt simply by watching an experienced fish perform the task.

蜂鸟知道其他哪些蜂鸟是小偷并破坏藏匿食物的地方；羊可以识别面孔；猩猩知道用各种小工具挖掘白蚁洞甚至用小武器捕猎小动物；海豚会模仿人类的姿势；印度喷水鱼捕食时会用水喷晕猎物，而学习怎样瞄准这一技巧仅通过观察前辈的做法。

I know that I can not expect to perform the arduous task with equal ability and success.

我知道我不能期望以相同的能力和功绩来执行这艰难的任务。

Now let them to perform their skillful aria respectively.

"If therefore", argues Bellarmine we can offer our prayers and our satisfactions in behalf of those detained in purgatory, because we are members of the great body of Christ, why may not the Vicar of Christ apply to the same souls the superabundant satisfaction of Christ and his saints--of which he is the dispenser?

" "因此，如果"，认为贝拉明（德indulgentiis ，十四）"我们可以提供我们的祈祷和我们满意的代表那些被拘留在炼狱，因为我们是成员的伟大基督的奥体，为什麼可能不是牧师基督适用於同样的灵魂满意的过剩是耶稣和他的圣人-他是在配药？
