数学模型设计能确定理论上属理想的情况。

Mathematical modelling can determine <em>theoretically</em> ideal conditions.

理论上这可能是对的；

<em>Theoretically</em> this may be true;

但是理论上是能够完成。

But you <em>theoretically</em> can do it.

从理论上来说，宇宙是无限的。

The universe is <em>theoretically</em> infinite.

这是理论上的正确位置。

This is the <em>theoretically</em> correct location.

理论上讲，两者是相通的。

<em>Theoretically</em> speaking, both is interlinked.

从理论上讲，这是可能的。

The models are <em>theoretically</em> self-consistent.

这些模型在理论上能够自圆其说。

The models are <em>theoretically</em> self-consistent .

从理论上讲，原子亦是如此。

<em>Theoretically</em>, atoms should behave this way, too.

理论上，答案显而易见。

<em>Theoretically</em> – yes, in reality – the answer is clear.
