A simulation can typically involve over 10,000 evaluations of the model, a task that was once only possible with the help of super computers.

模拟能够包含超过10,000个模型的评估，一项曾经只能借助超级计算机的帮助才能完成的任务。

Simulation results also might help in tweaking the process model to make simulation runs perform closer to the expected performance measurements.

模拟的结果还可以帮助对流程模型进行调整，以使得模拟运行执行的结果与期望的性能测定结果更为接近。

Using a NASA computer simulation, Oman and colleagues model the climate's response to the smoke from fires brought about by regional nuclear war.

奥曼和他的同事使用宇航局的一台计算机模拟器，提出了地区性的核战争引发的冲天大火、漫天烟尘，这时气候会有何反应的模型。

So the moral here, again, is whenever you're doing an implementation of a simulation, you do need to have some underlying theory about the model.

所以这里的寓意还是,不管你在做什么东西的仿真程序，你需要有一个,模型的底层程序。

Indeed, one principal purpose of the Bolshoi simulation is to compute and model the evolution of dark matter halos thereby rendering the invisible visible for astronomers to study, and to predict structures that astronomers could then seek to observe.

The researchers used a computer simulation model to estimate how many lives the screening programme could save, using data on death rates and the numbers of people affected by cancer from between 1975 and 2004.

The new computer simulation allows doctors and physicists to model the faulty heart beats (arrhythmias) that can cause cardiac arrest, and run episodes of arrhythmia time and again, looking for the best way of treating it.
